Question 1

How does Lit compare to React for building web components?

Accepted Answer

Lit is focused on lightweight, standards-based web components with a smaller footprint, while React is a full framework with a larger ecosystem. Lit components are interoperable across frameworks, but React offers more integrated tools and community support for complex applications.

Question 2

What's the best way to handle state management in Lit?

Accepted Answer

Lit provides reactive state out of the box, but for complex applications, you might need additional libraries or patterns. The @lit/context package can help with passing data through the component tree using events, and @lit/task handles asynchronous operations.

Question 3

Can I use Lit with TypeScript?

Accepted Answer

Yes, Lit has excellent TypeScript support, and there's a starter kit (lit-starter-ts) for TypeScript development. The documentation at lit.dev includes TypeScript examples, making it easy to set up and use in typed projects.

Question 4

How to integrate Lit components into an existing React app?

Accepted Answer

Use the @lit/react package, which provides a wrapper to use Lit web components as React components. This allows seamless integration, though you may need to handle prop passing and event handling carefully for optimal compatibility.

Question 5

Is Lit good for SEO?

Accepted Answer

SEO can be challenging with client-side rendering; Lit's SSR support is experimental (@lit-labs/ssr), so for SEO-critical applications, you might need to wait for mature SSR or use hybrid approaches like pre-rendering with tools like Eleventy.

Question 6

How to set up routing in a Lit application?

Accepted Answer

Lit doesn't have built-in routing; you can use the @lit-labs/router package (in labs) for basic routing, or integrate third-party routers. However, this requires additional setup and might not be as polished as routing in full frameworks.
