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.

## Installation

The Shopify Liquid Language Server is a [Shopify CLI](/docs/storefronts/themes/tools/cli/cli-2/commands) theme command.

## Usage basics

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

<p>
<div class="react-code-block" data-preset="terminal">
<div class="react-code-block-preload ThemeMode-dim">
<div class="react-code-block-preload-bar "></div>
<div class="react-code-block-preload-placeholder-container">
<div class="react-code-block-preload-code-container">
<div class="react-code-block-preload-codeline-number"></div>
<div class="react-code-block-preload-codeline"></div>
</div>

</div>
</div>


<script type="text/plain" data-language="bash">
shopify theme language-server
</script>

</div>
</p>


## Features

The Language Server offers the following features:

- [Documentation on hover](/docs/storefronts/themes/tools/shopify-liquid-vscode#documentation-on-hover)
- [Code completion and documentation](/docs/storefronts/themes/tools/shopify-liquid-vscode#liquid-code-completion-and-documentation)
- [Code formatting](/docs/storefronts/themes/tools/shopify-liquid-vscode#code-formatting)
- [Theme checks](/docs/storefronts/themes/tools/shopify-liquid-vscode#theme-checks)
- [Code navigation](/docs/storefronts/themes/tools/shopify-liquid-vscode#code-navigation)

To learn more about the features, refer to the [Shopify Liquid VS Code extension user guide](/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).
