SolidJS vs Vue, and Svelte

Quiz

Read this chapter to get an overview of SolidJS, Vue, and Svelte frameworks. These three frameworks share the same goal to provide easy-to-use components with efficient and fast rendering. Their goals may seem similar, but their working and internal designs are different from each other. In this chapter, we will be discussing the differences between SolidJS, Vue, and Svelte.

What is VueJS?

VueJS (pronounced like view) is a Progressive JavaScript framework for building interactive user interfaces and single-page applications. It was developed by Evan You and his team.

VueJS lets us extend HTML with HTML attributes known as directives. VueJS provides two types of directives: built-in directives and user-defined directives. VueJS uses double braces "{ { } }" for data holding.

Example

Let's have a quick look at a simple example in VueJS −

<template>
  <div>
    <h1>Welcome to {{ name }} Tutorial</h1>
    <input type="text" v-model="name" />
  </div>
</template>

<script setup>
import { ref } from "vue";

const name = ref("SoildJS");
</script>

In the above example, the ref() creates a reactive variable, and the v-model automatically binds the input value and updates the variable, and shows "Welcome to SolidJS Tutorial".

Pros of VueJS

Following are the pros of using VueJS for development −

VueJS enhances the static HTML without a build step.
Automatically embedded as web components on any page.
Helps in building single-page applications(SPA).
Provides both server-side rendering(SSR) and static site generation(SSG)
VueJS targets desktop, mobile, and WebGL.

Cons of VueJS

Following are the cons of using VueJS for development −

Smaller communities, as there are fewer third-party libraries and components than in ReactJS.
Templates, logics, and styles are grouped in a single file can lead to errors.
NativeScript VueJS is deprecated, and Ionic Vue is less popular, creating challenges for mobile development.

What is SvelteJS?

SvelteJS is a modern JavaScript framework for building interactive user interfaces that uses a compiler for the work. It was developed by Rich Harris and his team on 29 November 2016.

SvelteJS works as a compiler at build time, unlike traditional frameworks like ReactJS or VueJS, which perform the bulk of their work at runtime in the browser.

Example

Let's have a quick look at a simple example in SvelteJS −

<script>
  let name = "SolidJS";
</script>

<h1>Welcome to {name} Tutorial</h1>
<input type="text" bind:value={name} />

In the above example, let "name" be a reactive variable by default in SvelteJS, and bind:value={name} connects the input and variable for two-way binding, and shows "Welcome to SolidJS Tutorial".

Pros of SvelteJS

Given below are the pros of using SvelteJS for development −

SvelteJS is scoped styles and built-in functionalities.
No runtime framework, as the compiler does all the work.
It has great animation capabilities that help in building data visualizations.
When we write count += 1in SvelteJS, it automatically transforms it into reactive updates.

Cons of SvelteJS

Listed below are the cons of using SvelteJS for development −

Also have smaller communities, due to limited online support, tutorials, and troubleshooting resources.
As we debug compiled output, not your source code directly, it can lead to issues.
Not useful in making large applications.

What is SolidJS?

SolidJS is a Reactive JavaScript framework that is used to build high-performance interactive web applications. It was designed by Ryan Carniato, a known contributor in the JavaScript community.

SolidJS uses JSX, Component architecture, and unidirectional data flow, similar to React-based applications. SolidJS uses a compiled DOM, whereas ReactJS uses a virtual DOM for reactivity.

Example

Let's have a quick look at a simple example in SolidJS −

import { createSignal } from "solid-js";

function Demo() {
  const [name, setName] = createSignal("SolidJS");

  return (
    <>
      <h1>Welcome to {name()} Tutorial</h1>
      <input
        type="text"
        value={name()}
        onInput={(e) => setName(e.target.value)}
      />
    </>
  );
}

export default Demo;

In the above code, we have created a createSignal that creates a reactive variable called "name". So, whenever the input changes, the text updates instantly without re-rendering the component, and shows "Welcome to SolidJS Tutorial".

Pros of SolidJS

Given below are the pros of using SolidJS for development −

A fine-grained reactivity system in SolidJS helps with updates needed.
The bundle size of SolidJS is smaller, making the application faster.
SolidJS is easy to learn as compared to VueJS and SvelteJS.
Primitives can be used anywhere because the component body doesn't re-render, as there are no Hooks.

Cons of SolidJS

Following are the cons of using SolidJS for development −

It uses reactivity(signals), which can be difficult to understand for those coming from a React background.
Higher-level conditional rendering patterns do not re-render as expected sometimes.
It is not easy to find ready-made UI libraries, plugins, or third-party integrations for every use case.

Solid vs Vue vs Svelte

The following table highlights the differences between SolidJS, VueJS, and SvelteJS in terms of development −

Criteria	VueJS	SvelteJS	SolidJS
Type	Progressive JavaScript Framework	Compiler-based Framework	Reactive JavaScript Library
Reactivity	Uses ref() and reactive() APIs	Reactive by default with compiler handling	Uses fine-grained reactivity via createSignal()
DOM Handling	Virtual DOM	Compiled to minimal JavaScript (no Virtual DOM)	Compiled DOM (no Virtual DOM)
Learning phase	Easy to moderate	Moderate	Easy to learn, especially for React users
Performance	Good	High (no runtime overhead)	Very high (fine-grained reactivity)
Community Support	Large and active	Small but growing	Smaller compared to Vue and Svelte
Use Case	SPAs, SSR, SSG	Small to medium UI projects, animations	High-performance reactive web apps
