language-tools

• Purpose: Svelte Language Tools provides editor integrations and language support for Svelte files, enabling features like syntax highlighting, diagnostics, and autocompletion. It implements the Language Server Protocol (LSP) to power IDE plugins, including the official VSCode extension.

• Target Audience: Developers working with Svelte who want enhanced editor support, including type checking, linting, and intelligent code completion.

• Key Features:

  • Supports .svelte files, which mix HTMLx and JavaScript with Svelte-specific syntax.
  • Includes a language server (svelte-language-server) for LSP-compatible IDEs.
  • Provides a CLI tool (svelte-check) for type checking and diagnostics.
  • Offers a VSCode extension (svelte-vscode) for seamless integration.
  • Converts Svelte files to TypeScript-compatible JSX/TSX (svelte2tsx) for better tooling support.

• Framework Support: Primarily focused on Svelte, with deep integration for TypeScript and JavaScript workflows.

• Development: Built with TypeScript and uses pnpm workspaces for managing multiple packages. Contributions are encouraged, and the project includes detailed setup and testing instructions.
