How do I compile Typescript at Heroku postinstall?

Question

Instead of uploading the precompiled dist directory, I want to compile src at server side instead.

Here are my scripts inside package.json:

\"scripts\":

You need to call tsc from an npm script. Otherwise Heroku tries to find a global dependency named tsc.

Create a new npm script in your package.json:

"tsc": "tsc"

now replace "postinstall": "tsc" with:

"postinstall": "npm run tsc"
