Setup editors

Oxlint editor extensions start the language server with oxlint --lsp from your project installation, so oxlint must be installed in the project.

See Quickstart to install and run Oxlint from the command line.

Supported editors

• VS Code (and Cursor, etc.)
• Zed
• JetBrains
• coc.nvim
• Other editors

VS Code

Install

Download the official Oxc VS Code extension from:

• Visual Studio Marketplace
• Open VSX Registry

The extension is compatible with other VS Code-based editors, including Cursor.

Use (recommended setup for teams)

1. Recommend the extension in your repository so contributors install the same tooling.

Create .vscode/extensions.json:

{
  "recommendations": ["oxc.oxc-vscode"]
}

2. Enable fix-on-save (optional).

Add to .vscode/settings.json:

{
  "editor.codeActionsOnSave": {
    "source.fixAll.oxc": true,
  },
}

3. Enable type-aware linting (optional).

If you'd like to use type-aware rules and show type-related lint violations, ensure that typeAware is set to true in your VS Code settings (.vscode/settings.json):

{
  "oxc.typeAware": true,
}

You also need to ensure oxlint-tsgolint is installed in your project. See the type-aware linting docs for more details.
