+# decodal-wasm
+
+WebAssembly runtime package for Decodal.
+
+This package exposes the Decodal evaluator to browsers and other JavaScript runtimes that can load WebAssembly modules.
+It is generated from the Rust crate in `crates/decodal-wasm` with `wasm-pack` and is used by the official playground.
+
+Use `decodal-codemirror` separately when you need CodeMirror 6 language support.
+
+## Install
+
+```sh
+npm install decodal-wasm
+```
+
+JSR:
+
+```sh
+deno add jsr:@hare/decodal-wasm
+```
+
+## Usage
+
+```js
+import init, { evaluateProject } from 'decodal-wasm';
+
+await init();
+
+const result = evaluateProject(JSON.stringify({
+  entry: 'main.dcdl',
+  files: {
+    'main.dcdl': 'Server = { port = Int default 8080; };',
+  },
+}));
+
+console.log(JSON.parse(result));
+```
+
+The exported functions return JSON strings so callers can handle diagnostics and successful results without depending on Rust data structures.
