How to set env variable in local development for google cloud functions?

Question

I'm trying to run cloud function on my local system for which I need to set some env variables. I'm following docs for env and for local development docs.

I'm trying to run my project via the following command:

node node_modules/@google-cloud/functions-framework --target=syncingredients --env-vars-file=.env.yaml

Where my .env.yaml looks like:

API_KEY: key
AUTH_DOMAIN: project.firebaseapp.com

Answer 1

Seems like --env-vars-file aren't supported with functions framework (https://github.com/GoogleCloudPlatform/functions-framework-nodejs/issues/38)

I would recommend the workaround suggested by relymd-djk:

pre-req:

npm install env-cmd 
npm install yaml2json

modifying the package.json scripts section with:

"scripts": {
    "start":"yaml2json .env.yaml >.env.json && env-cmd -r ./.env.json functions-framework --target=syncingredients",
    "deploy": "gcloud functions deploy myFunction --entry-point syncingredients  --trigger-http --runtime nodejs16  --env-vars-file ./.env.yaml"
}

to run the function:

npm start

Thanks to ClumsyPuffin for highlighting that it isn't an available feature so I went for dotenv

Changed the file to .env:

API_KEY="key"
AUTH_DOMAIN="project.firebaseapp.com"

And used the following command to run the function locally

node -r dotenv/config node_modules/@google-cloud/functions-framework --target=syncingredients
