Setup editors

Editor extensions use oxfmt --lsp from your project, so oxfmt must be installed locally.

See Quickstart to install Oxfmt.

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.

Team setup

1. Recommend the extension for contributors:

.vscode/extensions.json:

.vscode/extensions.json

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

2. Enable format on save in .vscode/settings.json:

.vscode/settings.json

{
  "oxc.fmt.configPath": ".oxfmtrc.json",
  "editor.defaultFormatter": "oxc.oxc-vscode",
  "editor.formatOnSave": true
}

To set per language:

.vscode/settings.json

{
  "[javascript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  },
  "[typescript]": {
    "editor.defaultFormatter": "oxc.oxc-vscode",
    "editor.formatOnSave": true
  }
}
