Why Svelte should be your next frontend framework?

Introduction

Svelte is a new frontend framework with the most love on the StackOverflow survey in 2022. It has a unique approach to solving frontend development problems. Rather than following a traditional approach of using Virtual DOM like React and Vue frameworks, it uses a compiler to convert your code into highly optimized vanilla JavaScript. This means that your application will be much more lightweight and faster, as there won't be any additional runtime code to download and parse.

So here are the top 5 reasons why you should consider Svelte for your next project.

Low learning curve

Unlike other frameworks such as React, Vue, and Angular which require the learner to learn complicated syntax and APIs, Svelte doesn't require you to use a lot of unnecessarily complicated syntax to build small or large scale applications. Svelte is the most straightforward and easy to master framework. It has a low learning curve because of the simplexity of its syntax. With some basic web development skills such as HTML, CSS, Javascript, or Typescript, you can easily start exploring and building your website with ease. Even if you're new to frontend development, you should be able to pick up Svelte without any problem.

Less boilerplate

Like most modern frontend framework today, Svelte come with pretty much everything you need to ship your product to the market as soon as possible by reducing repetitive work and making the development experience a lot greater.

  • Two-way binding support: you can easily bind data to your form control and react to any change and perform computation tasks based on the changed value.
  • Component: defined and create components for your application to reduce code duplication as well as to keep the consistency of the UI across screens and projects.
  • State management: Svelte has simple build-in state management shipped out of the box to resolve sharing state issues between multiple components.

Great Performance

Application build on Svelte is incredible fast. This is because Svelte doesn't use Virtual DOM to update the content, style, and structure of the document. Instead, Svelte compiles your source code into a highly optimized vanilla Javascript which produces a comparatively small bundle size. Thus, reducing the bandwidth required for downloading resources by the client while keeping performance overhead at runtime and the memory footprint low to increase the responsiveness of the application. This result in up to 30% performance improvement in an application written in Svelte in comparison with an identical application written in any other framework.

A better development experience

What makes people so in love with Svelte is the experience they have while developing their project. From the experience I have while migrating my entire website from NuxtJS to SvelteKit, I love the simplexity and how amazing Svelte is designed. The syntax is pretty much easy to remember. If you were a VueJS or NuxtJS developer, learning Svelte is pretty simple because most knowledge is transferable with just a syntax change while the same concept remains.

Other than the simplexity of the design, Svelte is lightning fast out of the box. In development, my entire website is taking less than 350ms to run which is x23 times faster than the same version of the website written in NuxtJS. This saves a lot of hassle when the hot reload doesn't work as intended.

Out of box Jamstack support

Jamstack is a new approach to building decoupled web applications by separating backend and frontend from being bundled together into a single complicated piece of code. Its goal is to separate the UI from the data and business logic layer in other to achieve a secure, fast performance, and high scalability application.

By developing your web application on Svelkit, you can easily deploy your product for free or at a very low cost on most CDN and edge networks such as Cloudflare Page, Netlify, Vercel, and Google Cloud Hosting and switch between them with ease since Svelkit has everything in place ready to launch.

Bonus Tips

Similar to NextJS, SvelteKit comes with End Point (API Route), which makes the framework itself even more powerful since you can expose JSON and XML as an API and can be consumed by any application. It can also accept other HTTP requests such as POST/PUT/PATCH/DELETE from the client which is a lot handy for data submission and file upload.

In conclusion, Svelte is a great way to develop robust and high performance modern web applications. But, everything always comes with a cost. Since Svelte is still new to the market, its ecosystem is still limited compared to other popular alternative frameworks such as React and Vue. So, you may encounter some bugs, unresolved issues, fewer learning resources and material, and support on the way. Nevertheless, hand on experience is always the best way to learn new things.
