Pre-compiled tree-sitter grammars for 306 programming languages with TypeScript types.

What This Package Provides

• Parser access — load a tree-sitter language parser by name without wiring individual grammar crates or packages.
• Code intelligence primitives — parse trees, functions, classes, imports, exports, symbols, docstrings, diagnostics, and syntax-aware chunks.
• Shared cache model — parsers are fetched and cached once, then reused by every call in the process.
• Same catalog as every binding — Rust, Python, Node.js, Go, Java, PHP, Ruby, .NET, Elixir, WASM, Dart, Kotlin Android, Swift, Zig, and C FFI use the same grammar set.
• Node-first TypeScript API — native NAPI package with typed parser and query helpers.

Installation

npm install @xberg-io/tree-sitter-language-pack

Quick Start

import { getParser } from "@xberg-io/tree-sitter-language-pack";

const parser = getParser("python");
const tree = parser.parse("def hello(): pass");
console.log(tree.rootNode.toString());

Features

• 306 languages — pre-compiled tree-sitter grammars covering every major programming language and many minor ones.
• On-demand download + cache — parsers fetched at first use; subsequent runs hit the local cache.
• Code intelligence — extract functions, classes, imports, exports, symbols, docstrings, and diagnostics with one API.
• Syntax-aware chunking — semantic chunks for RAG/LLM pipelines.
• Polyglot bindings — native APIs across 15 languages: Rust, Python, TypeScript/Node.js, Go, Java, C#, Ruby, PHP, Elixir, WebAssembly, Dart, Kotlin, Swift, Zig, and C/C++ via alef.
