# Runtime assets

> Serve Grunt WebAssembly runtime files correctly in production

Your app must serve these runtime files:

```text theme={null}
grunt.js
_framework/*
```

If you use the npm package, these assets are in:

```text theme={null}
node_modules/@grunt/ckeditor5-grunt/_framework
```

## Requirements

* Copy runtime files into your build output
* Serve files over HTTP
* Avoid processing or rewriting runtime assets in bundling steps
* Serve correct MIME types for JS, WASM, and static files

If these files are missing or misconfigured, Grunt rendering and editing will fail at runtime.
