I worked with extensions for roughly 4 years on a handful of separate projects. I had managed a framework which abstracted over all APIs (including the insane old Safari one). While I can't share the framework, I have designed a code base architecture which allows incremental abstraction of APIs, uses typed message passing between scripts (with errors being propagated too), unit and integration tests or automation for compilation of the extension for each store according to their respective rules. This architecture is my IP and although I don't actively work with extensions on day to day basis anymore, I still do take on contracts to lay foundations or migrate existing projects. If this is something you're interested in, reach out to me via email in my bio.
