Have you have built an entire app in Lit and want to change to something else? Well, then you can place your current Lit application inside of your new framework and migrate whatever you want to the new framework's components.Īdditionally, many modern frameworks support output in web components, so that means that they can typically fit inside a Lit element themselves.ģ. If you don't like them, then you don't have to convert the entire app at once as web components work in other frameworks! Lit does not require a significant commitment to use! You can build components in Lit and add them to your existing project. In the meantime you can follow along with the Lit team's progress here.

The Lit team expects to release these tools externally on GitHub soon. At the time of writing this codelab, the Lit team has yet to release the SSR tools in a stable form, but the Lit team has already been deploying server side rendered components across Google products and has tested SSR within React applications. Lit 2 has been built with SSR support in mind. It's built with server side rendering (SSR) in mind You can simply open dev tools, select an element, and explore its properties or state.

This means that in order to inspect your components, you do not need to install any tools or exensions for your browser. Lit components are just HTML elements in the DOM. The Lit team has been working with the Lit community to help maintain projects that bring TypeScript type checking and intellisense to Lit templates at both development and build time with lit-analyzer and lit-plugin.

Though it is possible to write all of your Lit code in JavaScript, Lit is written in TypeScript and the Lit team recommends that developers use TypeScript as well! The Lit team has been working on an experimental project called which will automatically parse your Lit components and generate a React wrapper so that you do not have to use refs.Īdditionally, Custom Elements Everywhere will show you which frameworks and libraries work nicely with custom elements! First-class TypeScript support React is one of these frameworks, but it does allow escape hatches via Refs, and Refs in React are not a good developer experience. The only issues with framework interop is when the frameworks have restrictive support for the DOM. If it supports HTML elements, it supports Web Components. This means that building a component in Lit will work in current and future frameworks. Lit's components build off of a set of web standards called Web Components. The recent developer consolidation around native ES modules has been good for Lit – Lit is just normal JavaScript and there is no need for framework-specific CLIs or build handling. Though, if you want to, you can still build and optimize Lit code. With ES modules and modern day CDNs such as Skypack or UNPKG, you may not even need NPM to get started! This means that dev environments can be set up with a script tag + a browser + a server and you're up and running. With new browser features such as ES modules, and tagged template literals, Lit does not require compilation to run. LitElement (Lit's component base class) adds a minimal overhead to lit-html, but beats React's performance by 16-30% when comparing component features such as memory usage and interaction and startup times. In public benchmarks that compare Lit's templating system, lit-html, to React's VDOM, lit-html comes out 8-10% faster than React in the worst case and 50%+ faster in the more common use cases. Lit is tiny: it comes down to about 5kb minified and gzipped compared to React + ReactDOM's 40+ kb. Lit's core concepts and capabilities are similar to React's in many ways, but Lit also has some key differences and differentiators: It's small Not interested in following each individual step? Jump around as the sections do not need to be followed in order. You'll also need lit-plugin for VS Code and NPM.

How to translate several React concepts to Lit such as:Īt the end of this codelab will be able to convert React component concepts to their Lit analogs. With Lit you can build shareable components, applications, design systems, and more. Lit is a simple library for building fast, lightweight web components that work in any framework, or with no framework at all.
