How to attach debugger with firebase:shell - firestore clould functions

successfully configured firestore cloud functions in local.

able to run the functions locally using below command.

  1. firebase functions:shell --port=3535

firebase var data = require('./data'); wChangedEvent(data.default);

... ... printing whatever console.log there in wChangedEvent. So this is working properly.

But i need to attach debugger in visual studio code. I tried with below configuration.

   {
        "type": "node",
        "request": "attach",
        "name": "Attach",
        "port": 3535,
        "protocol": "inspector"
    },

But it is not working.

As of late 2020, this pull request added support for the --inspect-functions flag.

firebase functions:shell --inspect-functions

Unless you explicitly provide another, it will open the default node debugger port 9229.

With Jetbrains IDEs you can attach to the running process by using an "Attach to Node.js/Chrome" run configuration.

You can use the functions emulator. There is ver little documentation, but this is a good start: https://firebase.google.com/docs/functions/config-env

$ npm install -g @google-cloud/functions-emulator`

$ functions start

$ functions deploy api --trigger-http --timeout 600s

$ functions inspect api --port 9229

Create a VS Launce config:

{
  "type": "node",
  "request": "attach",
  "name": "Attach",
  "port": 9229 
}

Now you can F5 to start debugging.

This will not receive triggers from your database automatically, but it still very helpful as you can use an http request to trigger functions and debug them.

Tip: add this script to your package.json so you can easily npm run debug to build and deploy to the emulator:

"scripts": {
  ...
  "debug": "npm run build && functions deploy api --trigger-http --timeout 600s && functions inspect api --port 9229"` 
}
