Cloud Function: firebase deploy does not work

I am deploying cloud function but the TypeScript does not compile to Javascript. It does not event create lib/index.js

When I run firebase deploy, it shows the error that

Error: There was an error reading functions/package.json:

firebase deploy --debug shows the following log:

Error: There was an error reading functions/package.json:

 functions/lib/index.js does not exist, can't deploy Cloud Functions

Having trouble? Try firebase [command] --help

I have just tried it on another colleague’s Macbook, it works on his system perfectly, but not on my system.

Kindly help me with this.

Does functions/lib/index.js exist? Have you built your project before deploying? (npm run build).

I’d suggest adding npm run build to your deploy script:

package.json:

 "scripts": {
     "lint": "tslint --project tsconfig.json",
     "build": "tsc",
     "serve": "npm run build && firebase serve --only functions",
     "shell": "npm run build && firebase functions:shell",
     "start": "npm run shell",
-    "deploy": "firebase deploy --only functions",
+    "deploy": "npm run build && firebase deploy --only functions",
     "logs": "firebase functions:log"
   },

This randomly happened to be after I accidentally introduced a dependency from a file in /src on a function declared in /test. This caused the compiler to change the output structure and resulted in lib/src/... and lib/test/.... Moving the /test dependency to /src fixed the issue.
