#VSCode Extension

Editor integration for Rslint lives in the unified Rstack extension, which also provides Rstest testing and rs fmt formatting.

Install rstack.rstack from the VS Code Marketplace or, for Cursor, Trae, VSCodium, and other VS Code forks, from Open VSX.

The extension ships no tool binaries. It resolves @rslint/core from your project, so the editor runs the same version as your CLI and picks up your rslint.config.ts automatically. Rslint diagnostics are provided by the project's language server: real-time diagnostics as you type, code actions for auto-fixable rules, auto-fix on save, and multi-workspace support.

#Settings

#Auto-fix on Save

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

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