The Monaco Editor is the code editor that powers [VS Code](https://github.com/Microsoft/vscode), a good page describing the code editor's features is [here](https://code.visualstudio.com/docs/editor/editingevolved).
Please mention the version of the editor when creating issues and the browser you're having trouble in. Use the following two repositories when filing issues:
* [monaco-editor](https://github.com/Microsoft/monaco-editor) -- (TypeScript, JavaScript, JSON, CSS, LESS or SCSS advanced language support, and all color-only languages like bat, coffee script, cpp, csharp, fsharp, go, ini, jade, lua, objective-c, powershell, python, r, ruby, sql, swift, vb or xml colorizers)
In IE, the editor must be completely surrounded in the body element, otherwise the hit testing we do for mouse operations does not work. You can inspect this using F12 and clicking on the body element and confirm that visually it surrounds the editor.
## Installing
```
npm install monaco-editor
```
You will get:
* inside `dev`: bundled, not minified
* inside `min`: bundled, and minified
* inside `min-maps`: source maps for `min`
*`monaco.d.ts`: this specifies the API of the editor (this is what is actually versioned, everything else is considered private and might break with any release).
It is recommended to develop against the `dev` version, and in production to use the `min` version.
## Integrate
Here is the most basic HTML page that embeds the editor. More samples are available at [monaco-editor-samples](https://github.com/Microsoft/monaco-editor-samples).
var editor = monaco.editor.create(document.getElementById('container'), {
value: [
'function x() {',
'\tconsole.log("Hello world!");',
'}'
].join('\n'),
language: 'javascript'
});
});
</script>
</body>
</html>
```
## Integrate cross domain
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:
```html
<!--
Assuming the HTML lives on www.mydomain.com and that the editor is hosted on www.mycdn.com
> Q: What is the relationship between VS Code and the Monaco Editor?<br/>
> A: The Monaco Editor is generated straight from VS Code's sources with some shims around services the code needs to make it run in a web browser outside of its home.
> Q: Why all these web workers and why should I care?<br/>
> A: Language services create web workers to compute heavy stuff outside the UI thread. They cost hardly anything in terms of resource overhead and you shouldn't worry too much about them, as long as you get them to work (see above the cross-domain case).
> Q: I see the warning "Could not create web worker". What should I do?<br/>
> A: HTML5 does not allow pages loaded on `file://` to create web workers. Please load the editor with a web server on `http://` or `https://` schemes. Please also see the cross domain case above.
