Svelte vs. Angular vs. React: which framework is better? This question is often asked by those who work on their web development project. All three are extremely popular among developers. So, no wonder making the right choice can be challenging.

We’ll give you the first clue using the stats from Stack Overflow. Svelte leads the top favorite frameworks among developers, with over 71% dev satisfaction rate. React comes almost right after with 69%, and Angular falls slightly behind with a 55% satisfaction rate.

Today’s article will highlight the difference between Svelte JS, Angular, and React. We’ll discuss each framework’s advantages and disadvantages and compare their web development capabilities. After reading our post, you’ll have no doubts that Svelte is the best option. 

Svelte, React, and Angular: Pros & Cons Battle

Are Angular and React frameworks better than Svelte? Or are all these tech tools at about the same level? Well, we’re going to deal with that today. Let’s start with their pros and cons.

Svelte

Released in 2016, Svelte was meant to be a framework. Yet, it is a component framework developed to compile components down at the build step. It allows you to load a single bundle.js onto your page so that you can render your app.

In simpler words, you write components using HTML, CSS, and JavaScript with Svelte. During the development process, the framework compiles them into small, standalone JavaScript modules. Doing so ensures that the browser does as little work as possible, making your web app faster and code simpler.

Wrapping up, the Svelte pros are as follows:

• Easy to learn and use, No virtual DOM, Small package size, Fast rendering thanks to reactive programming, Component-based, which means you can reuse code, Client and server-side rendering support, Decent SEO support, Cross-platform

Although Svelte offers many advantages, it’s not entirely perfect. Here are some cons:

• Small community, No TypeScript support, The feature’s number may be limited

React

React is essentially a JavaScript library launched by Facebook in 2013. It is a declarative and component-based tool that enables the creation of dynamic and scalable user interfaces. React was also the first to introduce the virtual DOM.

Let’s take a quick look at its main pros:

• Easy to learn and use, Declarative, which makes code easy to debug and shows changes in components immediately, Component-based, which means you can reuse code, Flexible, Fast and performant, Large community and support from Facebook, Constant updates and innovations

Here are some cons that you may encounter in React development:

• Complex compilation of the framework, Poor documentation, The necessity of JSX syntax extension, The need to use a large number of tools

Angular

Angular is a JavaScript framework written in TypeScript. This technology is supported and constantly updated by Google, and the primary purpose of this framework is the development of single-page applications.

Let’s look at the pros that Angular offers:

• Modular, Component-based, which means you can reuse code, Detailed documentation, Numerous ready-made component, Top-notch security, Effortless work with a large code base, Fast server performance

While Angular is a decent tool for enterprise-scale products, it has some cons:

• Complex to learn, Large package size
• The need for time-consuming and complex dependency injection

Svelte vs. React vs. Angular: Comparison for Web Dev

A lot of engineers compare Svelte with other web development frameworks. As you now know, the most famous alternatives are React and Angular. So let’s discuss these three tools in greater detail.

Development Time

If we talk about the time it will take to develop your web solution, then Svelte is the winner again. This framework helps generate more readable and simple code, shorter than React or Angular. The learning curve for Svelte is likewise less steep than for the other two. All this significantly reduces development time.

Comparing React and Angular, these frameworks are quite similar regarding dev time. Yet, there are slight distinctions. React is easier to learn than Angular and provides extensive pre-built component libraries, thus, shortening the development time.

Security

Let’s now talk about the level of security offered by Angular, Svelte and React.

By default, Angular uses sanitization of input data and encoding of output data that is sent to the DOM. Thanks to this, it offers a top-notch level of security and reduces the number of vulnerabilities in your web solution.

React is considered a relatively secure framework compared to other JS tools, but it is still not entirely safe. This platform uses open-source components and does not have strong security settings by default. Hence, there is a possibility of weaknesses appearing in your product.

The same can be stated about Svelte. It is not to say that this framework offers a low level of security, but there is still some mistrust of it, especially given its newness and small community.

Installation & Project Setup

What about installing Angular, React or Svelte? See how you can do this and set up your project with these frameworks.

You need any text editor and NodeJS installed to get started with Svelte. To set up your project, you can use a degit template. 

As for Angular, ensure you have Node and NPM in your system. After that, you need to install Angular CLI and start your project. 

For React, you also need Node and NPM. After that, you should install React, where you will already be able to launch the project.

Routing

Now we offer to look at how routing occurs in the three frameworks we’re discussing today.

Svelte uses a filesystem-based router. In the codebase directories, you define the URLs that users can access. React binds URLs to components and does not support native routing because it’s a UI library. Angular enables routing to create SPAs with multiple views and navigation between them.

Frame 232

According to Stack Overflow, React is the second favorite framework with 69% of satisfaction rate among developers.

Testing

Let’s take a swift look at the testing means in React, Angular or Svelte. The Svelte and React frameworks offer their testing libraries. Angular, in turn, uses the Jasmine test framework.

Debugging

Speaking of the debugging process, Svelte is an absolute winner. It is because you get less code than with Angular and React.

As for other frameworks, debugging in Angular is easier than in React because only one tool is needed to execute the process, while React requires multiple tools.

Extensions

React offers developers the largest number of tools and libraries for creating web products. Because of this, you can bring almost any idea to life using this framework solely.

Angular also offers many well-integrated libraries and covers a wide range of features. This framework has everything you need to develop scalable web applications.

Svelte offers fewer extensions and tools than React and Angular. Yet, this is because this framework has a smaller community and is not backed up by tech giants like Facebook and Google.

Let’s summarize our comparison of React, Angular, and Svelte in the table below:

 

After learning more about the frameworks discussed, and you can already roughly decide on the choice. Read on to find out which tool your company suggests.

Framework Recommended for Web Development

If we were to choose between the frameworks described today, Svelte is our unquestionable choice. Why use Svelte instead of Angular and React?

Once again, for its benefits. They are:

• It is a component-based framework that requires no extra plugins
• It handles state management with none of the usual difficulties
• It makes use of scoped styling without needing CSS-in-JS, so no editor extensions or odd syntax is required
• It needs a simple build script to get going
• If you are starting a base project, hardly any files are needed

Furthermore, the most popular web frameworks, like Angular and React, are based on the idea of waiting until the code loading to build a virtual DOM. Only afterward can they render the page using the library.

Svelte, meanwhile, is a compiler. It compiles your components into JavaScript rather than relying on concepts like Virtual DOM to update the browser DOM. With Svelte, you can build an app much more expediently.

We also choose the Svelte for its blazing speed. It is considerably faster than Angular and React. It’s even competitive with Inferno, which is likely the speediest UI framework in the world. So, it’s a critical benefit when making a higher-speed application that can move you ahead of the competition.

 

Conclusion

We hope the facts we have provided supporting Svelte will help you make the right choice. While React and Angular are no worse, Svelte is the next-gen of frameworks. It is a lightweight and easy-to-implement solution, offering the best performance ever.

On top of the above, this framework sparks the most interest among software devs. So if you want to get a quality web product quickly and for reasonable costs, then pay attention to Svelte.
