IDE docs and troubleshooting

Svelte Language Tools contains a library implementing the Language Server Protocol (LSP). LSP powers theVSCode extension, which is also hosted in this repository. Additionally, LSP is capable of powering plugins fornumerous other IDEs.

A.svelte file would look something like this:

<script>letcount=$state(1);letdoubled=$derived(count*2);letquadrupled=$derived(doubled*2);functionhandleClick(){count+=1;}</script><buttononclick="{handleClick}">Count: {count}</button><p>{count} * 2 = {doubled}</p><p>{doubled} * 2 = {quadrupled}</p>

Which is a mix ofHTMLx and vanilla JavaScript (but with additional runtime behavior coming from the svelte compiler).

This repo contains the tools which provide editor integrations for Svelte files like this.
