+
+[![npm](https://img.shields.io/npm/v/@srcmap/remapping-wasm.svg)](https://www.npmjs.com/package/@srcmap/remapping-wasm)
+[![CI](https://github.com/BartWaardenburg/srcmap/actions/workflows/ci.yml/badge.svg)](https://github.com/BartWaardenburg/srcmap/actions/workflows/ci.yml)
+
+High-performance source map concatenation and composition powered by Rust via WebAssembly.
+
+**Concatenation** merges source maps from multiple bundled files into one, adjusting line offsets. **Composition** chains source maps through multiple transforms (e.g. TS -> JS -> minified) into a single map pointing to original sources. Alternative to [`@ampproject/remapping`](https://github.com/nicolo-ribaudo/source-map-js).
+
+## Install
+
+```bash
+npm install @srcmap/remapping-wasm
+```
+
+Works in Node.js, browsers, and any WebAssembly-capable runtime. No native compilation required.
+
+## Usage
+
+### Concatenation
+
+Merge source maps from multiple files into a single combined map:
+
+```js
+import { ConcatBuilder } from '@srcmap/remapping-wasm'
+
+const builder = new ConcatBuilder('bundle.js')
+
+// Add source maps with their line offsets in the output
+builder.addMap(chunkASourceMapJson, 0)      // chunk A starts at line 0
+builder.addMap(chunkBSourceMapJson, 1000)   // chunk B starts at line 1000
+
+const combinedJson = builder.toJSON()
+```
+
+### Composition / Remapping
+
+Chain source maps through a transform pipeline into a single map:
+
+```js
+import { remap } from '@srcmap/remapping-wasm'
+
+// Your build: original.ts -> intermediate.js -> minified.js
+// You have: minified.js.map (outer) and intermediate.js.map (inner)
+
+const composedJson = remap(minifiedSourceMapJson, (source) => {
+  // Called for each source in the outer map
+  if (source === 'intermediate.js') {
+    return intermediateSourceMapJson // upstream source map JSON
+  }
+  return null // no upstream map, keep as-is
+})
+```
+
+## API
+
+### `new ConcatBuilder(file?: string)`
+
+Create a builder for concatenating source maps.
+
+| Method | Returns | Description |
+|--------|---------|-------------|
+| `addMap(json, lineOffset)` | `void` | Add a source map JSON at the given line offset |
+| `toJSON()` | `string` | Generate the concatenated source map JSON |
+
+### `remap(outerJson, loader)`
+
+Compose source maps through a transform chain.
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `outerJson` | `string` | The final-stage source map JSON |
+| `loader` | `(source: string) => string \| null` | Returns upstream source map JSON, or `null` |
+
+Returns the composed source map as a JSON string.
+
+## Build targets
+
+```bash
+# Node.js (default)
+npm run build
+
+# Browser (ES module + .wasm)
+npm run build:web
+
+# Bundler (e.g. webpack, vite)
+npm run build:bundler
+```
