Best way to deploy TypeScript function to Cloud Function? #254
Description
I am using the TypeScript template to write the function and I faced some issues trying to deploy it using the gcloud functions deploy command.
I tried:
- The intuitive commando:
gcloud functions deploy pocReadFromBigQueryWriteToFirestore \
--runtime nodejs10 --trigger-http --allow-unauthenticated
Got the error
Deploying function (may take a while - up to 2 minutes)...failed.
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed: index.js does not exist; Error ID: e1b2ac36
- Then, passing a source argument pointing to the build/src directory.
gcloud functions deploy pocReadFromBigQueryWriteToFirestore \
--source=build/src \
--runtime nodejs12 --trigger-http --allow-unauthenticated
Got this error in the cli
Deploying function (may take a while - up to 2 minutes)...failed.
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Function failed on loading user code. This is likely due to a bug in the user code. Error message: Error: please examine your function logs to see the error cause: https://cloud.google.com/functions/docs/monitoring/logging#viewing_logs. Additional troubleshooting documentation can be found at https://cloud.google.com/functions/docs/troubleshooting#logging. Please visit https://cloud.google.com/functions/docs/troubleshooting for in-depth troubleshooting documentation.
And this one on the functions logs:
2021-02-04T17:47:55.029ZpocReadFromBigQueryWriteToFirestore Provided module can't be loaded.
Default
2021-02-04T17:47:55.029ZpocReadFromBigQueryWriteToFirestore Did you list all required modules in the package.json dependencies?
Next, I tried copying the package.json into the build/src folder and rerun the same command as above.
Deploying function (may take a while - up to 2 minutes)...failed.

Finally, I got it working by copying package.json to build/src/package.json and removing the scripts prepare, pretest and posttest. So, I got to think and I wonder:
- Why and how this scripts affect the deployment?
- What is the best strategy to deployment?
Thanks!
