What is a JS Framework?
From a large number of advantages, we can distinguish several key ones:
- Easy implementation of SPAs (Single Page Applications) and PWAs (Progressive Web Applications);
- Organised application structure;
- Shorter and cleaner code, which positively affects the speed of development, as well as the support and elimination of errors;
- App modularity, which makes it easier for several developers to work on the application simultaneously;
- The ability to quickly create a mobile and/or desktop cross-platform application from its web version using systems such as PhoneGap or Apache Cordova.
Angular is a framework from Google for building client applications. First of all, it is aimed at developing SPA solutions. In this regard, Angular came from Angular JS. At the same time, it’s not an update to its predecessor, but a fundamentally new framework.
- Thanks to the size of its community, there is a huge number of books, online resources, and conferences dedicated to Angular. This allows developers to stay relevant, and lets clients easily find companies to support their project.
- When creating templates in Angular, the declarative programming paradigm is applied, which makes the script more lightweight and easier to read and maintain. It happens due to the fact that the code describes the needed result instead of the steps required to accomplish it.
- A large number of useful features allows you to create the most user- and developer-friendly SPAs.
- Angular lets you organise applications from separate modules, which can be mutually dependant or autonomous.
- Angular modules are versatile and easy to manage. This modularization allows developers to load only the services they need at a given time, thus making automated testing more efficient. Plus, there is no need to remember the order of loading modules in case you adhere to the principle of “one file – one module”.
- Angular uses two-way binding: any changes in the user interface are immediately reflected in the application objects and vice versa. The framework itself monitors browser events, model changes, and user actions on the page to immediately update the necessary templates.
Since the release of our article, there have been two large updates of Angular. Here is the list of the new features in a few words.
What was new in Angular 14:
- A new feature called Standalone Component enables you to build your own components and use them anywhere in your app. The biggest benefit of standalone components is that you don’t have to worry about whether they’ll function with all the other various features of your app because they’re simpler to customise than other types of components.
- A rigid form of types can now be imposed on your forms using TypeScript. This makes it simpler to ensure that your forms are valid because each entry will be checked against its type when it is submitted and validated.
- The new Angular CLI functionality known as Angular CLI Auto-Completion offers auto-completion for the Angular command line interface (CLI). The feature uses the IntelliJ IDEA Plugin, which is built on TypeScript definition files.
- A brand-new diagnosis technique known as ng-template-error is available. When your application throws an error during runtime, this diagnostic will display the offending code within the error message.
- You can immediately alter the title tag of your pages from the <head> of your stylesheet. Now that HTML has more capabilities, you can input more information in the title tag.
What is new in Angular 15:
- Single-file components. This function is very important. It implies that component layouts can now be created as separate files rather than components. Sharing common styling choices and other components between apps or files will be easier as a result.
- Module loaders. Another intriguing new tool for Angular developers is module loaders. They enable users to import the appropriate modules at runtime without relying on WebPack or a similar loader. Any build system you use, such as Babel, Webpack, or Gulp, can be hacked with a module loader. Additionally, they don’t require any additional expenses because they are so lightweight.
- New API system. A new API method is presented in Angular 15 to make it simpler for developers to use modules. They can now be used out of the box – a significant shift from the previous versions, which lacked built-in support for them. With the new API system in Angular 15, interacting with APIs is also made simpler, since you no longer need to create code for every endpoint. To build data models, gain access to authentication systems, and work with JSON data from an API endpoint, you can use already existing tools. And having less written code improves the performance of your program.
- Stability. The new Angular 15 is compatible with earlier iterations of the framework. This is a crucial feature because it allows you to continue using your current applications without having to think about them evolving over time. Access control for form inputs has been enhanced with the new forms in Angular 15. Now you can limit input values based on type or length, making your forms more secure and less error-prone, no matter the intricacy.
- MDC Based Component. The MDC-based component is a brand-new type of component that enables you to use TypeScript to create your components in a much more declarative manner than before. It also makes it simpler to modularize your application by allowing you to use additional modules like NgModule and components. So rather than constantly inventing the wheel, you can reuse your components in various applications.
- You can always tell how your component will be rendered by merely looking at the source code. If you know the state, you know the result – no need to trace the progress of the program. This is especially helpful when developing a complex application as a team.
- Client rendering is the reason why certain services are so slow. You can render React right on the server, which makes for far faster performance.
- Thanks to the support of Facebook, there is a huge amount of documentation and online resources on the network that can help you in learning and using React.
- A simple component model and server-side rendering functionality allow for a faster, more flexible approach to work while using smaller block sizes.
There was one major update of React.js to version 18. Let’s see what’s new:
- Automatic batching. React can batch numerous state updates into a single re-render to improve performance. Without automatic batching, changes could only be batched inside React event handlers. Updates inside of promises, setTimeout, native event handlers, or any other event were not batched in React by default. But now these updates will be immediately batch processed with automatic batching.
- Transitions. To differentiate between urgent and non-urgent updates, React has introduced a new idea called a transition. Updates that are urgent represent hands-on activities like typing, clicking, pressing, and so forth. In order for urgent updates to match our preconceived notions of how physical objects act, there needs to be an immediate response. They feel “wrong” otherwise. But it’s different with transitions, since the user doesn’t anticipate seeing every intermediate value displayed on the screen. So it’s often best to use both, but differentiate between them using the new TransitionAPI.
- Suspense features. If a portion of the component tree isn’t quite ready to be displayed, Suspense allows you to declaratively define the loading state for that portion. The “UI loading state” becomes a first-class declarative notion in the React programming model thanks to the suspense. As a result, we can create more advanced features on top of it.
- New client and server rendering APIs. The APIs have been redesigned to support client and server rendering. With these adjustments, users are now able to use the outdated APIs in React 17 mode while upgrading to the new APIs in React 18.
- Strict Mode Behaviors. Strict Mode now has a new development-only validation thanks to React 18. Every time a component mounts for the first time, this new check will automatically unmount and remount each component, restoring the prior state on the second mount.
Vue is a progressive framework for building user interfaces. Unlike large monolithic frameworks, Vue is perfectly suitable for gradual implementation. Its core primarily solves the problems of the presentation level, which simplifies integration with other libraries and existing projects. What’s more, Vue is great for building complex single-page applications when it is used in conjunction with modern tools and additional libraries.
Since the release of our article, there have been no major updates on Vue.
- Vue.js allows for a fast transition from other frameworks such as Angular and React, due to their similarities in terms of design and architecture.
- Reinforced HTML means that Vue.js has a lot in common with Angular. This can help you optimize HTML block processing using different components.
- Vue.js helps develop fairly large reusable templates in no time, thanks to the simple structure of the framework.
- Vue.js can be conveniently used both for building single-page applications and for progressive web application interfaces. Most importantly, small interactive features can be easily integrated into existing infrastructures without negatively impacting the entire system.
Since the release of our article, there have been no major updates on Svelte.
- Svelte is a component framework designed to compile components at build time. With this approach, you can load just one bundle.js per page to render the entire application. This makes the web solution quicker and the coding process – easier.
- Svelte renders the DOM using reactive programming, which is, in general, much faster than the Virtual DOM. As a result, Svelte provides one of the quickest renderings from any framework.
- Svelte is beginner-friendly. There is no need to manipulate the DOM when you use it. You also don’t need to comprehend framework-specific state wrappers. Variables can be accessed directly from markup, and this greatly simplifies the process of creating a new application. With Svelte, programmers can learn the basics of the component’s state work without getting lost in all the intricacies that tend to plague similar frameworks. Some technicians presume that Svelte allows writing less code. Because code is terse there is less boilerplate, which leads to having less bugs.
- Svelte is open-source software developed by enthusiasts. Thus, using the Svelte framework is not costly and allows you to implement many features for free. Also, Svelte has an active developer community on GitHub that you can join and where you can always ask for help or contribute to this technology.
- It’s a compile-time framework and doesn’t require any framework-specific runtime. It has the smallest package size of any framework.
Preact and React share many similarities, including JSX, support for the React DevTools, HMR, and SSR, as well as the same modern API, components, and virtual DOM. Furthermore, there is no need to be concerned about speed degradation because Preact components are compatible with React.
Additionally, the program is open-source and accessible to everyone online for free use. Given that its initial releases took place in the middle of 2015, it’s intriguing that the Preact community isn’t as big as that of other JS web frameworks.
Since the release of our article, there were no major updates of Preact.
- Preact JS’s small size of only 3kb is actually its primary benefit. This contributes to it being among the lightest frameworks or tools you will ever encounter. Preact, unlike its older sibling React, which has an altitude of about 40kb, delivers a faster render performance despite being smaller.
- Preact is significantly more efficient at using memory than React is, which means the garbage collector will have less work to do.
- Preact provides a powerful command-line interface tool that will help you create innovative projects fast without having to deal with web pack or Babel.
- Preact has advanced capabilities even though it is a subset of React. The most important of them is actually the LinkState module, which optimizes state changes. React updates the state using arrow functions inside of a render() procedure. This specific method is inefficient and contains a ton of extraneous code. Preact resolves this problem by utilizing the LinkState module, which, when passed an event and returned a handle function, is in charge of automatically making changes to the component state.
- Preact makes use of the same ES6 API as React. This suggests that transitioning from React to Preact is simple for developers even when a project is already in production.
Generally speaking, Backbone.js is designed to build single-page applications and coordinate various web app components.
Since the release of our article, there have been no major updates of Backbone.
- When talking about download times and responsive apps, project weight is crucial. The capacity of Backbone.js is almost 7.6 kb, meaning it’s very light. It is built on the Underscores.Js libraries and completely removes the need for jQuery. Plus, the small size makes Backbone projects easy to scale.
- Backbone.js’ central concept is extensibility. It contains several tools that can be used for scaling software. Backbone.js can also be used to develop MVC frameworks. It’s made especially easy with the LayoutManager, which provides graphics for overviews, and Marionette, which improves program code structuring.
- Backbone supports abstract code, which serves a crucial role in programming. It also makes use of object-oriented programming, since it can conceal anything but object-specific data. Furthermore, Backbone uses RESTful API instead of DOM in order to support JSON and model-specific data formats.
- Backbone is easy to learn thanks to several factors. It has a ton of online literature and guides that can be read, and has been used in numerous applications. It can also easily synchronise with the backend of your software. And if the API is set up correctly, Backbone.js can effortlessly read, write, and delete several operations at a time.
- When a project expands, the jQuery declarations multiply and become dispersed, complicating the code and making it hard to understand. This issue is resolved by the event-driven communication used in Backbone.js. All the possible changes can be controlled by adding listeners to model properties.
- With backbone.js, writers can use standardised code instead of adhering to backbone conventions, since the latter can result in longer commands.
- Ember has a sizable and well-developed package environment, so you can be confident in being able to create the solutions you need. Additionally, the framework includes a devoted website with proper categorisation of all the packages, along with detailed documentation and individual ratings for each. You can make use of the standard NPM tools or quickly build your own add-ons by running the command “Ember add-on name”.
- You can communicate with the computer’s running system using Ember’s Command Line Interface for Ambitious Web Applications. You will receive a project framework with fantastic add-ons as a result, ensuring quick rebuilds and live reloads. This is the main tool for creating codes, performing live recompilations, and conducting tests in browsers. Most well-known frameworks, including Ember, use a CLI utility, proving how versatile it is. With the help of the Ember CLI, a complete app can be created quickly with just one command. It is also possible to determine the features that the application will have from the get-go.
- With the launch of Ember 2.0, the concept of stability without stagnation was first presented. It means that even though continuous improvement is the end goal, no one should be left behind. Ember is consequently backwards-compatible, meaning that no version update should break applications that are using earlier versions. The upgrading process will proceed without issue, and the user will be fully notified of any impending changes.
- Many well-known frameworks have community as one of their key selling points, and Ember JS is one of them. You can be certain that any issue you can possibly run into has already been solved, since Github has around 900 authors and Stackoverflow has more than 24,000 questions relating to Emer. The public is welcome to participate in the community’s completely open conversations, too. Additionally, the library contains a wealth of literature on how to get the most out of the framework.
