# Svelte Language Server
A language server (implementing the [language server protocol](https://microsoft.github.io/language-server-protocol/))
for Svelte.
Requires Node 12 or later.
## What is a language server?
From https://microsoft.github.io/language-server-protocol/overview
> The idea behind a Language Server is to provide the language-specific smarts inside a server that can communicate with development tooling over a protocol that enables inter-process communication.
In simpler terms, this allows editor and addon devs to add support for svelte specific 'smarts' (e.g. diagnostics, autocomplete, etc) to any editor without reinventing the wheel.
## Features
Svelte language server is under development and the list of features will surely grow over time.
Currently Supported:
- Svelte
- Diagnostic messages for warnings and errors
- Svelte specific formatting (via [prettier-plugin-svelte](https://github.com/UnwrittenFun/prettier-plugin-svelte))
- HTML (via [vscode-html-languageservice](https://github.com/Microsoft/vscode-html-languageservice))
- Hover info
- Autocompletions
- [Emmet](https://emmet.io/)
- Symbols in Outline panel
- CSS / SCSS / LESS (via [vscode-css-languageservice](https://github.com/Microsoft/vscode-css-languageservice))
- Diagnostic messages for syntax and lint errors
- Hover info
- Autocompletions
- Formatting (via [prettier](https://github.com/prettier/prettier))
- [Emmet](https://emmet.io/)
- Color highlighting and color picker
- Symbols in Outline panel
- TypeScript / JavaScript (via TypeScript)
- Diagnostics messages for syntax errors, semantic errors, and suggestions
- Hover info
- Formatting (via [prettier](https://github.com/prettier/prettier))
- Symbols in Outline panel
- Autocompletions
- Go to definition
- Code Actions
## How can I use it?
Install a plugin for your editor:
- [VS Code](../svelte-vscode)
## Settings
The language server has quite a few settings to toggle features. They are listed below. When using the VS Code extension, you can set these through the settings UI or in the `settings.json` using the keys mentioned below.
When using the language server directly, put the settings as JSON inside `initializationOptions.configuration` for the [initialize command](https://microsoft.github.io/language-server-protocol/specification#initialize). When using the [didChangeConfiguration command](https://microsoft.github.io/language-server-protocol/specification#workspace_didChangeConfiguration), pass the JSON directly. The language server also accepts configuration for Emmet (key: `emmet`), Prettier (key: `prettier`), CSS (key: `css` / `less` / `scss`) and TypeScript (keys: `javascript` and `typescript` for JS/TS config).
Example:
Init:
```js
{
initializationOptions: {
configuration: {
svelte: {
plugin: {
css: { enable: false },
// ...
}
},
typescript: { /* .. */ },
javascript: { /* .. */ },
prettier: { /* .. */ },
// ...
}
}
}
```
Update:
```js
{
svelte: {
plugin: {
css: { enable: false },
// ...
}
},
typescript: { /* .. */ },
javascript: { /* .. */ },
prettier: { /* .. */ },
// ...
}
}
```
