tsc: command not found / App Platform

Trying to deploy Node.js app (with TypeScript) with App Platform

I am getting tsc: command not found when trying to run build.

This is part of my package.json

"scripts": {
    "build": "tsc",
    "start": "node dist/index.js",
    "watch": "tsc -w",
    "dev": "nodemon dist/index.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  },

Tried to run npm install --only=dev && npm run build && npm prune --production

as was suggested in the threads below, but got: Your build job failed because it was terminated. This often happens due to resource exhaustion. Error code: BuildJobTerminated

Did "build": "npm install --only=dev && tsc" and it looks like its working.

When you push/publish your project, the Node environment changes from development to production… and in production mode, the tsc doesn’t work since typescript is added as a devDependency…

I solved this problem by adding typescript and @types/node to my regular dependencies by running npm install typescript @types/node

it works like a charm!

This is likely due to the fact that “typescript” package is a development dependency. You should move it to production dependency since the env is production.

Thanks @madrianhorning 🙏 npm install --only=dev fixed it for me.
