High-performance Markdown parser compiled to WebAssembly.

Installation

bun add @sylphx/synth-wasm-md

console.log(tree)

Performance

WASM parser provides ~2-5x speedup over pure JavaScript implementation for large documents.

| Document Size | JS Parser | WASM Parser | Speedup | |---------------|-----------|-------------|---------| | 1KB | 0.5ms | 0.3ms | 1.7x | | 10KB | 2ms | 0.8ms | 2.5x | | 100KB | 15ms | 4ms | 3.8x |

API

parse(markdown: string): Promise<WasmTree>

Parse Markdown text into an AST.

parseSync(markdown: string): WasmTree

Synchronous parse (requires WASM to be pre-initialized with initWasm()).

initWasm(): Promise<void>

Initialize the WASM module. Called automatically on first parse(), but can be called manually for eager initialization.

version(): Promise<string>

Get the version of the WASM parser.
