Unable to run firebase functions locally the ES6 imports are not working

[lohanidamodar]

Hi, I am using firebase-function-tools to write my firebase functions. However I am unable to run firebase functions on emulators locally. Imported import {functions} from 'firebase-functions' , functions is undefined. And there are other imports that are not working too. Is there any solutions. Thank you.

Hi @lohanidamodar

The import for the functions would look like this:

import * as functions from 'firebase-functions'

For me that works when I publish the functions but I haven't tried it with the emulators. I rather have a project just for development and test everything there ;)

I hope that this can help you. Let me know if you have more issues.

Check this out. It looks like it works. We just can't use the import

Thanks for providing firebase-function-tools.

Can I use the loadFunctions with ES6? Any sample?

[TarikHuber]

Did you try it with import loadFunctions from 'firebase-function-tools'

[tonprince]

Will try again and replace exports with variable.

@tonprince do you have any updates on this?

I switched to new cloud functions 2nd gen.

Hi there! I'm experiencing this issue as well. When trying to deploy the functions on local emulator, the follow error is thrown:

⬢ functions: Failed to load function definition from source: FirebaseError: Failed to load function definition from source: Failed to generate manifest from function source: Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/augustogiavedoni/-----/-----/backend/functions/node_modules/camelcase/index.js from /Users/augustogiavedoni/-----/-----/backend/functions/node_modules/firebase-function-tools/lib/load.js not supported.
Instead change the require of index.js in /Users/augustogiavedoni/-----/-----/backend/functions/node_modules/firebase-function-tools/lib/load.js to a dynamic import() which is available in all CommonJS modules.

Seems to me that the problem is that firebase-function-tools uses an outdated version of the camelcase package (currently using v5.3.1 and latest is 7.0.1).
