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
• 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 also 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,
  },
}
