Watching for changes & Typescript

Hi,

As this is the recommended way to run functions locally, is there a way to use Typescipt and to watch files?

Thanks,

Expected Behaviour: Running functions-framework --watch would restart the functions framework if any of the *.js files in the app (eg the main index.js and it’s dependancies) change

Actual Behaviour: New feature

Steps to Reproduce the Problem New feature

I just use

"debug-watch": "npx tsc-watch --onSuccess 'npx @google-cloud/functions-framework --target=sendMail'"

Based on @QuantumInformation’s excellent answer, we’ve ended up using the following:

"dev": "tsc-watch --onSuccess 'functions-framework --target=testFuction'"

Then just npm run dev.

Bonus: If you want to add the typescript source files to a different folder /app, then:

• In tsconfig.json change "outDir": "./dist" and "rootDir":"./app"
• In package.json change to "main":"./dist/index.js"
