Rslint VS Code Extension

The official VS Code extension for Rslint, a high-performance JavaScript and TypeScript linter written in Go.

📦 Installation

• VS Code: Install the extension from the VS Code Marketplace
• Cursor/Trae: Install the extension from the Open VSX Registry.

⚙️ Configuration

The extension can be configured through VS Code settings:

rslint.enable

• Type: boolean
• Default: true

Enable/disable Rslint.

rslint.corePath

• Type: string
• Default: ""

The extension uses the nearest @rslint/core installation for each open file. This follows normal node_modules ancestry, so a monorepo can use a root installation, nested versions, or both. Runtimes backed by the same physical installation are shared within a workspace folder.

Yarn Plug'n'Play is not resolved or executed. Use a regular local installation or set rslint.corePath to an exact package directory.

Set rslint.corePath to an @rslint/core package directory to override automatic resolution. Relative paths are resolved from the workspace folder. The extension does not ship a fallback core, so the project must install one. If an installation is replaced in place without changing its package directory, reload the VS Code window so its Node-loaded code and binary refresh together.

rslint.trace.server

• Type: "off" | "messages" | "verbose"
• Default: "off"

Traces the communication between VS Code and the language server.

🔧 Auto-fix on Save

To automatically fix lint issues when saving, add the following to your VS Code settings (.vscode/settings.json):

{
  "editor.codeActionsOnSave": {
    "source.fixAll.rslint": "explicit"
  }
}

• "explicit" — Fix on manual save only (Ctrl+S / Cmd+S) — recommended
• "always" — Fix on every save, including auto-save
• "never" — Disable auto-fix on save
