Best Android Libraries For App Development

“An app is not all about technology. It is a dream towards the future”. Everyone around us who has a smartphone must be using tons of android apps in their daily life. From purchasing goods online to attending online classes, we all need one application to fulfill our demands. It would be very difficult if we don’t have an application for our work. So have you ever wondered how these apps are made?


Android App Development is the most preferred technology at the present time. It allows people to explore the world of Android and gain exposure as much as they want. It is a process of creating android applications for devices running on the Android Operating System. Android apps can be written in programming languages like Java, C++, Kotlin, and Python.


However, to cut short the chase of writing elongated codes for every application, we make use of android libraries. They are programs that implement behaviors and have a well-defined interface as well as programming languages. They help the developer in creating optimized apps without getting tired as the process can be accomplished within a few steps by using some well-defined pre-written codes instead of writing them from scratch. It’s impossible to overlook the construction of bug-free, highly responsive apps with minimal resources. Not to forget the precise, quick, effortless, and featured-rich android app development attained by them.


Let’s take a look at some awesome libraries that can help us to create better Android apps.


 Image loading Libraries:-

Working with images is one of the inevitable parts of Android app development. If one is willing to display efficient images on the application, it needs to take care of the image caching. So in this article let’s discuss some image loading libraries in Android.

  • Picasso – By using Picasso the process of displaying images from external locations is simplified. It also supports complex image transformation, automatic caching to the disk image view recycling, and also downloads translation in an adapter. What’s unique is that this library handles every stage of the process; it starts from handling HTTP requests and also handles the caching of the image.
  • Glide – Glide is similar to Picasso and can load images from many sources while taking care of caching and keeping a low memory impact when doing image manipulation. It provides animated GIF support that handles image loading, caching, fetching, displaying or decoding and is one of the top image loading libraries for android that is recommended.


Video Displaying Libraries:-

Displaying videos poses another difficult task during development. The process and details to take care of can be too numerous to handle. In this category, however, the most popular and powerful one is Exoplayer.

  • Exoplayer – There is an Android media library developed by Google that provides an alternative to the built-in Android MediaPlayer for playing Audio and Video both locally and over the internet. Exoplayer supports the features that are not currently not supported by Android Media Player like DASH and Smooth streaming adaptive playbacks.


Dependency Injection Libraries:-

Dependency injection is a concept where an object does not need to configure its dependencies. Instead, dependency is passed by another object. This principle helps us to decouple our classes from their implementation. It is worth noting that this is a good software engineering practice because it makes our code loosely coupled, which makes it easier to maintain and test. There are many dependency injection libraries but Dagger 2 seems to be the lord of them.

  • Dagger 2 – Dagger 2 is a fully static, compile-time dependency injection framework for both Java and Android. When developing a large application you don’t want to handle dependency injection yourself because the code will grow quickly and become extremely difficult to maintain. Dagger helps this because it creates dependency injection graphs in compile-time via annotation.


Networking Libraries:-

Here are the tools that you need for establishing any kind of network communication within the Android app.

  • Retrofit – Retrofit allows you to define your rest API as an interface you can flexibly manipulate the API requests, body, header, query parameters, and much more via annotations which can make everything clean and simple. Lastly, it also allows synchronous API execution which at times is a lifesaver.


View Binding Libraries:-

View binding libraries emerged when assigning views to variables and having access to them in the activity class. Libraries in this area are limited. Basically, there is one worth mentioning.

  • Butterknife – Butterknife is a library that helps us assign ids to views easily thereby avoiding the excess findViewById. According to the documentation, “Butterknife is like Dagger only infinitely less sharp”. This means that view binding can be seen as a form of Dependency Injection. In butterknife, annotations are used to generate boilerplate code for us instead. But unfortunately, this tool is now deprecated. Developers are switching to View binding. View binding is a feature that enables you to more efficiently write code that interacts with the viewer.


Scanning Libraries:-

These are useful for including the scanning functions in any android application.

  • CAMView – It is a basic access library for Android cameras that includes a QR scanner. It’s a simple Android library for using the device camera in apps. Structuring the layout files gives developers rapid access to a variety of functionalities. Low-level procedures such as camera, orientation, setup, streaming, and many more are handled by this library. It can be used for gaining access to users’ cameras and utilizing them to accomplish tasks, such as scanning barcodes with a built-in ZXing decoding engine.


Drawing Libraries:-

These libraries assist developers in making their apps creative by allowing for creative drawing and out-of-the-box thinking.

  • MyLittleCanvas – This library is used for facilitating efficient working with canvas on android, where now one may use objects instead of methods. It is used to provide features to TextViews such as a custom underline. One can also use Canvas techniques to implement RectShape, LineShape, RoundRectShape, TextShape, DrawableShape, CircleShape, and PathShape.
  • AnimatedPieView – This library is best suitable for those developers who prefer to include animations in their applications. It provides the feature of including animations while drawing charts, the transformation between a ring chart and a pie chart, positioning of the text field as well as alpha animation on touch.


In order to find the ideal library to be used while creating an application, one can consider the factors of reliability of authors, the popularity of a library, authentication of a library’s license, highly recommended libraries, well-written library, open-source and key features of the library.

Being an Android Developer is a difficult job. To construct an industry-standard working application, you’ll need to be familiar with the libraries, languages, and other tools. Android app libraries make the development process easier for developers.

One of the main reasons for adopting Android libraries is to speed up and optimize the development of Android apps. Instead of executing these activities from the start, these Android libraries provide developers with basic pre-written codes or other pieces that they can use immediately.

Thus, making use of these inbuilt android features helps the developer to save loads of time and effort while bringing his imagination into the reality of an app via android development.

Practices for securing your native mobile apps

In today’s world, the phone has access to practically all of our personal and sensitive information, from conversations to healthcare records and bank account information. When data becomes a valuable resource, many people want to profit from it, but some of them are unwilling to ask your permission first. As a result, mobile app security is not a benefit or a feature, it is a bare necessity. App security should be a priority at any given time to avoid any sort of information breach.


When you consider our current relationship with our smartphones containing mobile apps, you’ll realize that a large portion of our life-critical data is floating around in cyberspace, accessible to a plethora of hackers.  One breach and the criminal has direct access to our name, age, home address, account details, and even our current location within a few meters.


With all this at stake, we understand that native mobile apps are a target focus for all malicious activities and thus there is a dire need to practice mobile app security right from the developing stage.


What is mobile app security?

It is the process of examining and testing mobile applications, web applications, and APIs to ensure that they are safe from potential attacks. Alternatively, it is the process of protecting high-value mobile applications and your digital identity from all types of fraud.

Some examples of application security are malware, tampering, key loggers, reverse engineering or any other form of interference or manipulation.


Common threats to mobile app security

  • Insecure communication: Data is often shared in a client-server method in apps. When the app sends data, it does so through the internet and then through the mobile device’s carrier network. Attackers could take advantage of mobile security flaws to intercept users’ data or sensitive information as it travels across the network.
  • Data leakage: When downloading an app, users frequently fill up prompts to begin using it without thoroughly considering the application’s permissions. This pattern can be used by some apps to obtain more information about users for future advertising purposes or to resell it for a hefty amount.
  • Insecure data storage: It can occur in a variety of locations throughout your mobile app, including cookies stores, binary data stores, and databases. The risk of employing an insecure data storage system is that it could be hacked owing to problems with frameworks, jailbroken devices, or malicious attacks. If an attacker acquires access to a database or device, they can alter a legitimate app to extract data for their own use.
  • Reverse engineering: If an attacker can see one’s code, they will be able to devise more effective attacks against one’s application. It can be used to figure out how the program works on the back end, edit the source code, and reveal encryption mechanisms in use, among other things. As a result, the code written for a mobile app could be exploited against the developer, posing serious security threats.
  • Inadequate logging and monitoring: Logs and audit trails provide visibility into all network operations, allowing your firm to quickly troubleshoot faults, detect incidents, and track occurrences. They’re also beneficial for meeting regulatory standards. Inadequate or incorrect logging and monitoring generate information gaps, making it difficult to prevent and respond to a security problem.
  • Cryptography problems: Mobile cryptography protects data and applications, and it’s essential for security. Developers may employ encryption algorithms that have known flaws or don’t utilize encryption at all. Threat actors can take advantage of these flaws or steal data from a hacked mobile device.


Now, let us discuss the practices that should be followed by the developers and/or the users to keep their mobile apps safe and secure.

  • Strong authentication enforcement: Developers should make sure that their applications preferably take strong alphanumeric passwords. It’s also worth requiring users to update their passwords on a regular basis. Biometric identification employing facial ID or fingerprints can improve security for particularly sensitive applications.
  • Source code security: Because the majority of code in a native mobile app is client-side, mobile malware may readily trace faults and vulnerabilities in the source code and design. Reverse-engineering is commonly used by attackers to repackage well-known programs into malicious ones. After that, they post the programs to third-party app stores in order to lure unwary consumers. Encrypting the source code, which ensures that it cannot be read, can be considered a good way to defend your application from these attacks.
  • Code obfuscation: Obfuscation is the process of changing the application’s source code into something unreadable and is difficult to read by humans. Before developing the application, this is generally done by automated tools. The only purpose is to make reverse-engineering your source code from a generated application more difficult. Developers should incorporate tools to discover and address security problems when designing applications.
  • Secured server and network connections: Because of dangers such as man-in-the-middle attacks through WiFi and cellular networks, IT developers should encrypt all communications between mobile apps and app servers. If your server is hacked, one is most likely to lose the app’s data, along with his/her users’ confidence, and the brand’s reputation.
  • Best and latest cryptography implementation: If you want your encryption efforts to pay off, key management is essential. Never hard code the keys because this makes them easy to steal for attackers. Keep your keys in a safe place and never save them locally on your device. Even the most widely used cryptographic algorithms, such as MD5 and SHA1, are frequently insufficient to meet the constantly changing security needs. This is why it’s critical to stay current with security algorithms, and to employ encryption methods like AES with 512-bit encryption, 256-bit encryption, and SHA-256 for hashing whenever possible.
  • Scanning and testing: By testing the applications for malicious intent, malware and adware can be eliminated. Virtual sandboxing and signature-based scanning technologies can both be used to detect malware. Malware scans should be run on the server for mobile workspace and virtual mobile solutions.
  • Backend security: A client-server approach is used in the vast majority of mobile applications. Because the authentication and API transport protocols change from one platform to the next, it’s important to double-check all APIs for the mobile platform you’re working on. One needs to always check who is accessing the services and keep critical data in memory to a minimum.
  • Data caching optimization: Cached data is typically stored on mobile devices to improve the performance of an app. As a result, those particular apps and devices become more vulnerable, and attackers can easily hack and decode the cached data; which results in frequent data stealing. If the nature of the data is particularly confidential, one can demand a password to use the app. This will help to mitigate the risks connected with cached data.
  • Secured APIs: Unauthorized APIs that aren’t well-coded can unintentionally provide a hacker access to sensitive information. APIs are used for the majority of jobs nowadays, and ignoring them could result in substantial security risks. Even though it makes a coder’s life easier, it also provides a backdoor for attackers to take advantage of privileges.



Always keep in mind that security isn’t something you can put up like a structure and then forget about. You must monitor and review security policies and practices in a proactive and comprehensive manner. The most important or crucial thing is to provide current solutions to the problem.

Web App vs Mobile App: What Should Your Startup Choose?

For years, the argument between online and mobile apps has raged on. In the internet market, desktop purchasing still has a significant value, but smartphone business sales are currently on the rise.

The world of web apps and mobile apps has grown to such an extent that the debate has shifted to specific online media vs. other online media.

Before coming to a conclusion and choosing sides, let us first weigh out both options by understanding the key differences between the two.


Web apps

In layman’s terms, a web application or mobile website is a responsive website that responds to being seen on a smartphone and offers interactivity. They function in the same way that downloadable apps do, but are accessed via one’s internet browser. Being responsive here states that these applications can adapt or shrink down to the size of the device we are using to view them.

For Example, Google drive, Netflix, Microsoft office, and pocket.

  • Functionality: Web apps are more versatile and offer a wider range of functions, including those specifically designed for mobile apps as well.
  • Sustainability: these are self-sustainable i.e. they run on an active internet connection and do not require regular updating of features.
  • Build and design: programming languages like JavaScript, CSS, HTML, and Python are commonly used to create web apps. There is no standard development kit but developers still have access to referential templates. These are typically faster and easier to create.


Mobile apps

Apps designed for smartphones, tablets, and other small touch devices are known as mobile apps. They are installed and downloaded from an app store, and they have access to system resources. They are installed and operated on the device itself.

For Example, Instagram, Snapchat, and Facebook.

  • Functionality: Mobile app users often get more limited functionality, as many of these apps are designed to serve a particular purpose.
  • Sustainability: Mobile apps must be downloaded and installed before they can be used. They may also work offline. They do, however, necessitate the user downloading updates on a regular basis.
  • Build and design: A mobile web app is usually made up of Client-side scripting languages, such as JavaScript or CSS, that rely on your browser to run programs. Languages like Python, Objective-C, and Java are commonly used for server-side scripting. There’s also HTML, which is used as a markup language.


Because they are both mobile-driven, it is evident that both mobile and web apps appear to be excellent options. One needs to consider the company’s business purpose and, ultimately, the end goals to evaluate whether or not a web app or mobile app is appropriate.


Firstly,  let us have a look at the different criteria that help web apps to outweigh the features of mobile apps.

  • Vicinity or accessibility: Users can visit a web app via a browser on a variety of devices immediately at any given time. Apps, on the other hand, necessitate the user downloading and install the app before viewing the content or the application itself.
  • compatibility: A web app can reach the audience on a variety of mobile devices, whereas native apps require the development of a separate version for each device type. Web apps can be operated on all devices having a stable internet connection.
  • Shareability and outreach: A simple link of a web app can be used to share URLs between users. It has a significantly broader reach than a mobile app because it is available across platforms and can be readily shared among users as well as search engines.
  • Cost-effective: a web app is comparatively less expensive or cost-effective to build than a mobile app as it requires fewer resources and labor.
  • Time effective: along with being cost-effective, a web app is considerably time effective as well when it comes to both development and usage.
  • Visibility: Because one can find pages displayed in search results and included in industry-specific directories, mobile websites are considerably easier for users to find. Apps are usually restricted to manufacturer app stores in terms of visibility.
  • Lifespan or longevity: The usual shelf-life of an app is very short, thus unless your software is truly unique and/or beneficial, its longevity on a user’s device is uncertain. On the other hand, mobile websites are always available for consumers to return to.


Now, we ponder the different criteria that help mobile apps to outweigh the features of web apps.

  • Customization or personalization: Mobile apps are designed in such a way that users can make essential modifications to the way they want to use them. Users’ experiences can be enhanced by features that allow them to save data, set preferences, and share media assets on social media.
  • Interactive: apps such as gaming apps involving high user interaction are likely to provide an enhanced user experience than web apps.
  • Native functionality: Even if web apps are getting better at accessing mobile-specific services like click-to-call, SMS, device libraries, GPS functions, and accessing a user’s camera or processing power, an app will still do so much efficiently.
  • Offline capacity: mobile apps are capable of working and providing access to content offline locally. This is ideal for use in places with no internet access or wireless connection.
  • Faster services: Mobile apps are quicker than mobile websites. The capacity of apps to save data locally and get the appropriate dataset promptly is a functional benefit as compared to web apps.
  • Instant update notifications: The ability to send push notifications to consumers who have the app loaded on their smartphone is an intrinsic feature of apps, allowing app publishers to communicate directly with users. It keeps customers informed about new offers and forthcoming sale seasons that are relevant to their preferences.


Most web design and development companies would advise you to build a website first and then a mobile app later because this is the most cost-effective alternative. You will benefit from having all of your material displayed on a single website interface. Furthermore, upgrading content on a mobile app is easier than updating content on a website.


However, to make a decision or choice, you need to consider the following

  • The target audience of your company – their needs, interests, wants and goals
  • Products and services offered by your company
  • Essentiality of user experience for your products or services
  • Importance or need of user interaction for the same – need for user engagement
  • The popularity of a mobile app or web app in your venture’s niche
  • Company’s budget to invest and develop either of them


As India transitions to a digital economy, all enterprises and start-ups are hard at work developing websites and mobile apps. But the question is, which one will help your company grow? The main concept is that in the future, everyone will have an Android phone rather than a laptop or other device, but people still prefer viewing the details in a larger screen display or interface in order to get a clearer insight and easier functioning.

Unless you’re launching a mobile-focused business, building a website first is the way to go. Rather than investing a major portion of your budget in the development of an app. Alternatively, you may work on making your website more user-friendly.

In conclusion, there are numerous factors to consider before deciding whether you should build applications or websites or go for the development of both. It is entirely up to you and your business plan.

Best Practices in CSS

CSS stands for Cascading style sheet that is used to style and layout web pages. For example, you can use CSS to change your font size, color, family, etc. To use CSS like a pro, you must follow some tricks to keep your code clean and optimized. Whether you are an expert or a beginner you must follow these steps that are best for your website design.


1. Organized code

You don’t need to put all of your CSS in one file unless you’re going to use it. If a user arrives at the home page, only the styles for that page should be included. Essential styles are the ones that the user sees after the page loads, while non-essential styles are those that have been concealed, such as dialogue, snack bars, and notifications. Elements or components that must be activated by the user.

Maintain a sense of order. Instead of throwing in ids and classes in whatever sequence that comes to mind, use a logical framework. It will assist you in remembering the cascading aspect of CSS, which allows you to use style inheritance in your stylesheets.


2. Top-Down approach

It’s always a good idea to organize your CSS so that you can find parts of your code easily. A top-down approach that addresses styles as they arise in the source code is what I recommend.

The readability of your CSS is crucial, despite the fact that most users don’t realize why. Because you’ll be able to identify elements faster if your CSS is well-read, it will be a lot easier to maintain in the future. Furthermore, you never know who might need to look at your code in the future.


3. Lazy Loading

There are various ways to lazy load CSS, but using bundlers like WebPack and experimenting with dynamic import makes it a lot easier. You can make your own Javascript CSS loader or use the <link> tag to delay non-critical CSS when including stylesheets in your website.

Images and iframes can both benefit from lazy loading. This image or iframe should not be loaded until it is visible in the viewport.”


4. Shorthand CSS

You may wish to specify padding-top or border-right at times, but I’ve found that I frequently return to these to add more, so I’ve adopted the habit of always using the shorthand to make it easy to update without providing many attributes. It’s simpler to alter and has fewer lines of code.

When writing CSS, you can significantly reduce the size of your code by using shorthand. You can mix styles in one line for elements like padding, margin, font, and others. A div, for example, may contain the following styles:

#box {

    margin-left: 5px;

    margin-right:   7px;

    margin-top: 8px;


It can be written as


    margin: 8px 7px 0px 5px;



5. Utility Classes

If you frequently utilize the same tricks or styles, make them into class utils that can be applied directly to the HTML element. These are things like a center with display flex or grid for me, so I make a class called .center-flex and a class called .center-grid. To automate these repetitious style combinations, use class utilities.


6. Consistent code

The importance of consistency cannot be overstated. Even if you’re doing everything wrong, stick with it because it’ll be easier to correct afterward. Adopt a CSS approach, organize styles in the same way, establish how many levels you nest selectors, and so on. Define your personal style and stick to it, refining it through time.

Making sure your CSS is consistent goes hand in hand with keeping your code readable. You should start creating your own CSS “sub-language” that allows you to label things easily. There are certain classes that are created nearly in every theme, and you can call them by the same name every time. For example, use .caption-left to float images with a caption to the left.


7. Preprocessors

A preprocessor goes through your raw files and turns them into a stylesheet. CSS preprocessors enable you to write less CSS in a more efficient and effective manner. They’re jam-packed with tools and features that will help you manage your CSS, avoid duplication, and modularize it. Using a preprocessor such as LESS or SASS aids in the creation of clean code.


8. Avoid Inline CSS

Only the use of the !important flag can overwrite an inline style, and as you’ll see in the next block, the !important flag can be problematic, even though inline styles require it. A further reason to avoid them is that you included an external stylesheet for a reason, and that reason is to keep style and structure distinct (HTML). There are exceptions, but if you have a style in your external stylesheets, a style in HTML, or a style in Javascript, it becomes difficult to track what is causing the change, and it becomes difficult to manage as the codebase increases.

Content and presentation are mixed up when inline styles are used. Inline styles are just as terrible as relying on strictly appearance HTML elements like the font. It results in clumsy code, as each HTML file must be modified individually in the event of a style change, rather than a single global modification in a single external stylesheet.


9. Avoid !important

You’ll need to add the !important flag if you’re using Bootstrap and actually want to replace a style, but why are you using Bootstrap in the first place? If you find yourself needing to utilize the !important flag, it’s usually a hint that something is wrong. You might be using a difficult-to-overwrite third-party library; you might be using inline styles; you might be using selectors that are too particular; you might have a CSS hierarchy or order issue, or you should try to grasp how CSS specificity is computed.

However, you should avoid doing so because using !important with a large number of elements will eventually result in !important losing its meaning. Because every CSS rule now bypasses selector specificity.


10. Relative Units

You should make an effort to use relative units more frequently. Words like em, rem, percent, vw, vh, fr, and so on. Although there are occasions where these value units are required, setting fixed values with px and pt should be reserved for static design. Your website and units should be flexible, much like the browser.

Ems is more scalable with different browser screens and mobile devices than pixels, which are a more static means to describe font sizes. With the rise of multiple forms of online browsing (laptop, mobile, etc. ), ems and rems are gradually becoming the standard for font size measures since they provide the most versatility.



Comments are the most integral part of all programming, markup, and scripting language. Commenting is beneficial; use it! Add a comment if you develop difficult hacks or find scenarios when something works but you don’t understand why. Add comments for complicated items, organize your CSS, assist others to understand your reasoning and plan, and help you make sense of your mess when you return to it later.

Simply type /* behind the comment and */ to close it, as shown below:

/* This is a CSS Comment */


12. Reset CSS

Every browser has a different default style for the elements, so it’s possible that your object will look one way in one browser and another, or that it will have an extra border or shape that you weren’t anticipating. By resetting or normalizing your CSS, you can expedite these processes and ensure that your style looks consistent across all browsers. Browser inconsistencies such as heights, font sizes, margins, and headings are essentially eliminated when you reset your browser. The reset ensures that your layout is consistent across all browsers.


13. CSS Compressors

CSS compressors reduce the size of CSS files by eliminating line breaks, white spaces, and merging elements. This combination can significantly reduce file size, resulting in faster browser loading. CSS Minifier and HTML Compressor are two great online CSS compression tools. It’s worth noting that while reducing the size of your CSS can improve efficiency, it also reduces readability.


14. Browser Developer tools

Modern web browsers include a number of essential features that any web developer should have. All of the major browsers, including Chrome, Firefox, Safari, and Edge, now provide these development tools. You may visually inspect, alter, and edit CSS in real-time using the Chrome and Firefox developer tools, which include features like debugging JavaScript, evaluating HTML, and viewing errors.


15. Validate your CSS
Validating your CSS gives you more than a sense of accomplishment: it also aids in the detection of flaws in your code. If anything doesn’t appear right when you’re working on a design, try running the markup and CSS validator to see what issues come up. Usually, you’ll discover that you neglected to close a div or that a semicolon in a CSS attribute was missing.



This concludes our CSS  Best Practices Guide. Understanding, writing, and organizing CSS is an art form. No one can become a better CSS writer overnight; it takes time and effort. These have been quite beneficial to me in my CSS adventure, and I am confident that they will be beneficial to you as well.

How to Boost Your Web App Speed by 10x!

In this tech-savvy generation, having a web application for your business is a necessity. More and More people are moving towards e solutions for their real-world problems. Like booking a cab, buying groceries, online shopping for clothes, and many more. So, If you want to reach a huge target audience for your business, having a website is a must.

However, only having a web app will not suffice, you need to have a marvelous web application to come into the eye of your target audience. Business owners who are considering developing new web applications or who are responsible for maintaining current ones must recognize the importance of application speed. Think of all the times you browsed a website on your laptop or mobile and it didn’t open or work properly in the first two minutes. As soon as something like that happens, you either start refreshing the page or close the website and move to another one. Remember the time, when you downloaded an app and it wasn’t working properly and in the first five minutes you uninstalled it from your device. So, we can say that the first few minutes when a user visits your web applications are very crucial. Those few minutes can make or break your brand’s image in the eye of the user. Keeping this in mind, we can understand the fact that the speed of our web application is an influential factor for your web app.

 In this blog, we’ll learn about 10 ways by which we can increase the speed of our web app. Let’s get started.


1. Use Caching

Defining caching mechanisms for users’ browsers can help the app run faster. Don’t forget to specify the caching techniques for the user’s browser to improve the performance of your web app. Although browsers make every effort to regulate caching, they believe it is usually wiser to prevent caching by default rather than caching by request.


2. Remove Render-blocking JavaScript and CSS

CSS and JavaScript that block rendering should be limited — this enhances the user experience. Accessibility, maintainability, customization, consistency, portability, and performance are all dependent on the Stylesheet. You can improve the user experience by using non-blocking assets and allowing users to fetch and render HTML markup before the CSS is loaded and parsed. JavaScripts follow the same rule. Aside from that, you may expect the CSS and JS files to be compressed for use. This will minimize the file size and increase the speed with which your web app loads.


3. Images

PNGs should only be used when absolutely necessary; otherwise, JPEGs should be used. For logos and other images, JPEGs are always preferable over PNGs. This is because PNG images are large and take longer to load, slowing down the application’s performance. Second, you must examine the image resolution required and design images accordingly.

At the backend of every image, there is some redundant data that can slow down the pace of your app. Therefore, you must remove metadata from your photos, minimize their size, and speed up your web app. SVG pictures could be used for graphics visuals since they are vector-based, display high-quality at all resolutions, and are yet small. As a result, you might consider using these for icons or logos.


4. Server-side Rendering

As not every JavaScript solution for single-page apps has increased server-side rendering, it’s best to stick with more developed options like React and Angular2.


5. Mobile First CSS

If your customers have older devices, switching to non-bloated CSS would be a wise decision. It will assist in reaching a 10x increase in app speed. This is because non-bloated CSS makes extensive use of classes, limiting the lines of code read by the browser. Aside from that, the finest application development companies also recommend using mobile-first CSS. It’s built on the premise that app developers should wrap all desktop CSS in media queries and use mobile as the default. Because mobile device browsers don’t read the code in media queries, your app will execute faster, resulting in more efficient web app development.


6. CDNs

The CDN (Material Delivery Network) is a worldwide distributed system of proxy servers that works to provide high-availability and high-performance content to users. It can considerably improve the time it takes for clients all across the world to respond to your assets. As a result, you should pay attention to them. The implementation of a content delivery network can enhance user response times to files.


7. HTTP Requests


A long load time can be a disruptive and frustrating experience for your users. Mobile users will have a particularly bad experience, as most of them will have to wait until every asset on a webpage is downloaded before the page even begins to appear in their mobile browser. So, we must try to minimize HTTP requests.


8. HTTP compression 

Web performance can be improved by using HTTP compression. HTTP compression reduces the size of data transmitted. We recommend allowing compression for all files, with the exception of those that have already been compressed, because it improves web performance significantly. To compress data, all major browsers support gzip with the Content-Encoding header. This enables the transmission of fewer bytes to browsers, resulting in speedier content delivery. Incompatible browsers, you can also employ a more efficient brotli compression technique.


9. Lazy loading

One of the most important performance gains for first page loads with several images is to load the images only when they are in or near the viewport this is known as Lazy Loading. To achieve the same outcome, you may either utilise the IntersectionObserver functionality incompatible browsers or alternative tools such as react-lazyload.


10. HTTP/2 Protocol

The HTTP network protocol has been updated to HTTP/2 (h2 in DevConsole). Because of the following differences between HTTP/1.x and HTTP/2, switching to HTTP/2 may increase performance:

  • HTTP/2 is a binary protocol, not a textual one. It’s easier to parse and more compact.
  • HTTP/2 is multiplexed, meaning it can send several requests at the same time over a single TCP connection. It eliminates the need to worry about browser connection restrictions per server or domain sharding.
  • It reduces request/response size overhead by using header compression.
  • Allows servers to send answers in advance. This is a particularly intriguing feature.


The web is being taken over by mobile apps. The speed of the web app has a significant impact on its success. The capacity to launch programs at breakneck speed ensures that your company stands out in a crowded market! With the growing popularity of mobile applications over desktop websites, it’s critical that you take the necessary steps to increase the speed of your web app. the speed of your web app, which will not only improve the user experience but also help you construct a successful web app in order to stand out from the competitors. Remember that a lightning-fast application can help you carve out a special place in the customer’s mind and spirit! As a result, your application’s conversion rate may improve.

In a growing application, performance is a never-ending process that usually necessitates regular adjustments throughout the entire stack. There are a plethora of intriguing ideas to try. I hope that this information encourages you to consider performance in your application:
