Here is a quick example, for the public AddonManager API: https://firefox-source-docs.mozilla.org/toolkit/mozapps/extensions/addon-manager/AddonManager.html
To use it for your own code:
Check that JSDoc generates the output you expect (you may need to use a @class annotation on “object initializer”-style class definitions for instance)
- Create an .rst file, which may contain explanatory text as well as the API docs. The minimum will look something like
- Ensure your component is on the js_source_path here in the sphinx
Run mach doc locally to generate the output and confirm that it looks correct.
