# Shopify Liquid Language Server

The [Language Server Protocol](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/) enables developers to provide code editing features to all code editors in a single codebase with no code editor-specific code.

***

## Usage basics

The Language Server is started by running the following CLI command:

## Terminal

```terminal
shopify theme language-server
```

***

* [Code formatting](https://shopify.dev/docs/storefronts/themes/tools/shopify-liquid-vscode#code-formatting)

* [Theme checks](https://shopify.dev/docs/storefronts/themes/tools/shopify-liquid-vscode#theme-checks)

  To learn more about the features, refer to the [Shopify Liquid VS Code extension user guide](https://shopify.dev/docs/storefronts/themes/tools/cli/language-server).

***

## Editor integration

Every editor has its own way of integrating with Language Servers, but the principle is always the same: telling the editor how to start the Language Server.

[View some example implementations in the Theme Tools repo](https://github.com/Shopify/theme-tools/wiki).
