Google Cloud Function Boilerplate

Setup

• Signup for Google Cloud
• Create a new project project.
• Install the gcloud cli tool.

   brew cask install google-cloud-sdk

• Login

   gcloud auth login

• Find the project id you just created and set it as the current project.

   gcloud projects list
   gcloud config set project translator-246304

Development

• (optional) If you want to use gcloud services, you'll need to create some credentials.

   gcloud iam service-accounts create chet-dev

• Add an owner policy

   gcloud projects add-iam-policy-binding translator-246304 --member "serviceAccount:chet-dev@translator-246304.iam.gserviceaccount.com" --role "roles/owner"

• Create the credentials file.

   gcloud iam service-accounts keys create credentials.json --iam-account chet-dev@translator-246304.iam.gserviceaccount.com

• Start the development server (you may have to build the first bundle npm run build before you do this.)

   npm start

• Test that its working

   curl curl http://localhost:8080/

Deploying

• Read about it here
• Build the TypeScript files:

   npm run build

• Edit the package.json deploy script to reference the name of the function you want to deploy. Currently, it's called translate.
• Deploy

   npm run deploy

• The deployment should log an endpoint url that you can test.

   curl https://us-central1-translator-246304.cloudfunctions.net/translate
