What's Web Component Libraries?

Web Component Libraries are collections of reusable UI components built using Web Components standards, allowing for encapsulation, interoperability, and reusability across different frameworks and applications. These libraries leverage technologies like Custom Elements, Shadow DOM, and HTML Templates to create components that can be easily integrated into any web project, regardless of the underlying framework. Examples include Stencil, Lit, and Svelte, each offering unique approaches to building and managing web components while promoting best practices in web development.

Feature Comparison: svelte vs lit vs @stencil/core

Component Creation

  • svelte:

    svelte enables component creation using a unique syntax that combines HTML, CSS, and JavaScript in a single file. It compiles components into highly optimized JavaScript, eliminating the need for a virtual DOM and resulting in faster updates and smaller bundle sizes.

  • lit:

    lit provides a straightforward way to create web components using template literals and reactive properties. It emphasizes simplicity and performance, allowing developers to define their component's structure and behavior with minimal code.

  • @stencil/core:

    @stencil/core allows you to create web components using a simple, declarative syntax with support for TypeScript, JSX, and CSS. It provides a powerful CLI and build system that automatically handles tasks like code splitting, lazy loading, and generating documentation.

Performance

  • svelte:

    svelte offers exceptional performance by compiling components into efficient JavaScript code that updates the DOM directly, bypassing the need for a virtual DOM. This results in faster rendering and updates, making Svelte one of the most performance-oriented frameworks available.

  • lit:

    lit is designed for high performance, with a focus on minimizing re-renders and efficiently updating the DOM. Its use of reactive properties and efficient rendering algorithms ensures that components update quickly and use minimal resources.

  • @stencil/core:

    @stencil/core generates highly optimized web components with features like tree shaking, lazy loading, and automatic polyfills for older browsers. This ensures that the components are lightweight and only load the necessary code, improving overall performance.

Reactivity

  • svelte:

    svelte has a built-in reactivity system that automatically tracks changes to variables and updates the DOM when those variables change. This makes it easy to create highly interactive components with minimal effort.

  • lit:

    lit features a reactive programming model that automatically updates the DOM when reactive properties change. It uses a simple API to define reactive properties, making it easy to create dynamic and interactive components.

  • @stencil/core:

    @stencil/core provides reactivity through the use of decorators and state management within components. It supports one-way data binding and allows for reactive updates when component properties change.

Community and Ecosystem

  • svelte:

    svelte has a passionate and rapidly growing community, with a rich ecosystem of plugins, tools, and resources. Its unique approach to component development has garnered a lot of attention, making it a popular choice among modern web developers.

  • lit:

    lit has an active and vibrant community, with strong support from Google and a growing ecosystem of libraries and tools. It is widely used for building web components and has a rich set of documentation and resources.

  • @stencil/core:

    @stencil/core has a growing community and is backed by Ionic, which provides a rich ecosystem of components and tools for building web applications. Stencil is increasingly being adopted for creating design systems and component libraries.

Ease of Use: Code Examples

  • svelte:

    Creating a simple web component with svelte

    <script>
      export let name = 'Svelte';
    </script>
    
    <style>
    h1 {
      color: green;
    }
    </style>
    
    <h1>Hello, {name}!</h1>
    
  • lit:

    Creating a simple web component with lit

    import { LitElement, html, css } from 'lit';
    
    class MyGreeting extends LitElement {
      static styles = css`h1 { color: blue; }`;
    
      render() {
        return html`<h1>Hello, Lit!</h1>`;
      }
    }
    customElements.define('my-greeting', MyGreeting);
    
  • @stencil/core:

    Creating a simple web component with @stencil/core

    import { Component, h } from '@stencil/core';
    
    @Component({
      tag: 'my-greeting',
      shadow: true,
    })
    export class MyGreeting {
      render() {
        return <h1>Hello, Stencil!</h1>;
      }
    }
    
How to Choose: svelte vs lit vs @stencil/core
  • svelte:

    Choose svelte if you prefer a modern framework that compiles your components into highly efficient JavaScript at build time, resulting in smaller bundles and faster runtime performance. Svelte is great for building entire applications or components with a focus on simplicity, reactivity, and a clean syntax that reduces the need for boilerplate code.

  • lit:

    Choose lit if you want to build fast, lightweight web components with a simple and expressive API for rendering. Lit is particularly suited for projects that require high performance and minimal boilerplate, making it easy to create dynamic and interactive components with a focus on reactivity and declarative rendering.

  • @stencil/core:

    Choose @stencil/core if you need to create highly optimized, framework-agnostic web components with a focus on performance and standards compliance. Stencil is ideal for building a design system or a library of reusable components that can be used across multiple projects and frameworks.

What is Svelte?

Svelte is a new way to build web applications. It's a compiler that takes your declarative components and converts them into efficient JavaScript that surgically updates the DOM.

Learn more at the Svelte website, or stop by the Discord chatroom.

Getting started

You can play around with Svelte in the tutorial, examples, and REPL.

When you're ready to build a full-fledge application, we recommend using SvelteKit:

npx sv create my-app
cd my-app
npm install
npm run dev

See the SvelteKit documentation to learn more.
