yarn link doesn't run prepublish script, so what else can I do to develop an ember addon locally?

I have an addon that is linked to my app (for local dev) using yarn link

This creates a symlink in node modules to the addon directory.

However, I am using ember-cli-typescript, which has a prepublish script that builds my .ts files into .js, so when I am developing locally, prepublish doesn't get run, my .js do not get created, and the app crashes.

Maybe I could .gitignore all the .js and have them get built in ember-cli-build.js ?

Or should I be doing something besides yarn link for local dev?
