Monaco Editor
The Monaco Editor is the code editor that powersVS Code, a good page describing the code editor's features is here .
Issues
Please mention the version of the editor when creating issues and the browser you're having trouble in.
This repository contains only the scripts to glue things together, please create issues against the actual repositories where the source code lives:
monaco-editor-core:Issues -- npm module (Issues with the editor itself) monaco-typescript:Issues -- npm module (Issues with JavaScript or TypeScript language support) monaco-languages:Issues -- npm module (Issues with bat, coffee script, cpp, csharp, fsharp, go, ini, jade, lua, objective-c, powershell, python, r, ruby, sql, swift, vb or xml) Known issues
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 .
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:

FAQ
Q: What is the relationship between VS Code and the Monaco Editor?
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: What is the relationship between VS Code's version and the Monaco Editor's version?
A: None. The Monaco Editor is a library and it reflects directly the source code.
Q: I've written an extension for VS Code, will it work on the Monaco Editor in a browser?
A: No.
Q: Why all these web workers and why should I care?
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: What is this loader.js ? Can I use require.js ?
A: It is an AMD loader that we use in VS Code. Yes.
