browser (Rust/WASM core).\n\n## Build\n\n```bash\npnpm install\npnpm build:wasm # build WASM (web + Node)\npnpm build # compile TS and copy WASM into packages/fastmd/dist\n```\n\n## Test\n\n```bash\npnpm test # unit tests; integration tests run when WASM is built\n```\n\n## Benchmark\n\n**fastmd only:**\n\n```bash\npnpm build:wasm:node\npnpm bench\n```\n\n**Compare vs react-markdown and Bun’s native markdown:**\n\n1. Build WASM: `pnpm build:wasm:node`\n2. Optional: install react-markdown for comparison:\n ```bash\n pnpm add -D react-markdown react react-dom\n ```\n3. Run comparison (Node):\n ```bash\n pnpm bench:compare\n ```\n4. Or run under **Bun** (uses Bun’s runtime; Bun’s native markdown is included if your Bun version exposes it):\n ```bash\n bun run crates/fastmd-core/bench/compare.bench.ts\n ```\n\nSame fixture and iteration count for all parsers; output is ops/sec so you can compare.\n\n## Usage\n\n**Node.js** (sync, no init):\n\n```js\nimport { parseToTokens, renderHTML } from \"@abhi1264/fastmd\"\nconst tokens = parseToTokens(\"# Hello\\n\")\nconsole.log(renderHTML(tokens, \"# Hello\\n\")) //

Hello

\n```\n\n**Browser** (async init once):\n\n```js\nimport initfastmd, { parseToTokens } from \"@abhi1264/fastmd\"\nawait initfastmd()\nconst tokens = parseToTokens(\"# Hello\\n\")\n```\n\nSee [docs/INIT.md](docs/INIT.md) and [docs/STREAMING.md](docs/STREAMING.md).\n\n## Supported syntax\n\n| Feature | Supported |\n|--------|-----------|\n| Headings (`#`–`######`) | ✅ |\n| **Bold** (`**` / `__`) | ✅ |\n| *Italic* (`*` / `_`) | ✅ |\n| ~~Strikethrough~~ (`~~`) | ✅ |\n| `Code` inline | ✅ |\n| Fenced code blocks (`` ``` ``) with optional language | ✅ |\n| [Links](url) | ✅ |\n| Autolinks `` | ✅ |\n| Blockquotes (`>`) | ✅ |\n| Unordered lists (`-` / `*` / `+`) | ✅ |\n| Ordered lists (`1.` …) | ✅ |\n| Horizontal rule (`---` / `***`) | ✅ |\n\n**Not supported:** raw HTML, tables, task lists, definition lists, footnotes, front matter. Use a full CommonMark/GFM parser if you need those.\n\n## Render options\n\n`renderHTML(tokens, src, options)` accepts:\n\n- `linkTarget` – e.g. `\"_blank\"` for links\n- `headingIdPrefix` – prefix for heading `id` (slug from text)\n- `codeClassPrefix` – prefix for code block class (e.g. `\"language-\"` for syntax highlighting)\n\n## React components (optional)\n\nFor custom React components per element (like react-markdown):\n\n```js\nimport { parseToTokens, renderToReact } from \"@abhi1264/fastmd/react\"\nconst tokens = parseToTokens(\"# Hi\\n\")\nconst nodes = renderToReact(tokens, \"# Hi\\n\", {\n a: (props) => ,\n})\n```\n\nRequires `react` as peer. Import from `fastmd/react`.\n\n## Token format\n\nParse returns a flat `Uint32Array`: 4 u32 per token `[kind, start, end, aux]`. Use `tokensFromBuffer(buf)` to get `Token[]`, or `parseToTokens(md)` for the full string → tokens pipeline. `start`/`end` are UTF-16 code unit offsets for correct `src.slice(start, end)` in JS.\n","readmeFilename":"README.md"}
