## Integrating the AMD version of the Monaco Editor in a cross-domain setup
|
|
|
|
Here is the most basic HTML page that embeds the editor, using AMD, in the case that the editor sources are hosted on a different domain (e.g. CDN) than the document origin.
|
|
|
|
More self-contained samples are available at [monaco-editor-samples](https://github.com/Microsoft/monaco-editor-samples).
|
|
|
|
If you are hosting your `.js` on a different domain (e.g. on a CDN) than the HTML, you should know that the Monaco Editor creates web workers for smart language features. Cross-domain web workers are not allowed, but here is how you can proxy their loading and get them to work:
|
|
|
|
Assuming the HTML lives on `www.mydomain.com` and the editor is hosted on `www.mycdn.com`.

# Option 1: Use a data: worker URI
|
|
|
|
* `https://www.mydomain.com/index.html`:
|
|
```html
|
|
<script type="text/javascript" src="http://www.mycdn.com/monaco-editor/min/vs/loader.js"></script>
|
|
<script>
|
|
require.config({ paths: { 'vs': 'http://www.mycdn.com/monaco-editor/min/vs' }});
|
|
|
|
// Before loading vs/editor/editor.main, define a global MonacoEnvironment that overwrites
|
|
// the default worker url location (used when creating WebWorkers). The problem here is that
|
|
// HTML5 does not allow cross-domain web workers, so we need to proxy the instantiation of
|
|
// a web worker through a same-domain script
|
|
window.MonacoEnvironment = {
|
|
getWorkerUrl: function(workerId, label) {
|
|
return `data:text/javascript;charset=utf-8,${encodeURIComponent(`
|
|
self.MonacoEnvironment = {
|
|
baseUrl: 'http://www.mycdn.com/monaco-editor/min/'
|
|
};
|
|
importScripts('http://www.mycdn.com/monaco-editor/min/vs/base/worker/workerMain.js');`
|
|
)}`;
|
|
}
|
|
};
|

|
require(["vs/editor/editor.main"], function () {
|
|
// ...
|
|
});
|

</script>

# Option 2: Host on your domain a worker proxy

```

self.MonacoEnvironment = {
