Firestore Cloud Functions
This is code that doesn't make sense on the frontend client, e.g.
- Long-running or slow operation (database)
- Tasks that need to be run every so often (syncing email list to Mailjet)
- Anything we should't trust to clients (secrets, auth)
If you want to make and test changes, you'll have to do a bit of setup...
Installing
Adapted from https://firebase.google.com/docs/functions/get-started
$ cd functions
to switch to this folder$ yarn global add firebase-tools
to install the Firebase CLI globally$ yarn
to install JS dependencies$ firebase login
to authenticate the CLI tools to Firebase$ firebase use dev
to choose the dev project
For local development
$ firebase functions:config:get > .runtimeconfig.json
to cache secrets for local dev- Install gcloud CLI
- If you don't have java (or see the error
Error: Process java -version has exited with code 1. Please make sure Java is installed and on your system PATH.
):$ brew install java
$ sudo ln -sfn /opt/homebrew/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
$ gcloud auth login
to authenticate the CLI tools to Google Cloud$ gcloud config set project <project-id>
to choose the project ($ gcloud projects list
to see options)$ mkdir firestore_export
to create a folder to store the exported database$ yarn db:update-local-from-remote
to pull the remote db from Firestore to local- TODO: this won't work when open source, we'll have to point to the public db
Developing locally
$ firebase use dev
if you haven't already$ yarn serve
to spin up the emulators- The Emulator UI is at http://localhost:4000; the functions are hosted on :5001. Note: You have to kill and restart emulators when you change code; no hot reload =(
$ yarn dev:emulate
in/web
to connect to emulators with the frontend- Note: emulated database is cleared after every shutdown
Firestore Commands
db:update-local-from-remote
- Pull the remote db from Firestore to local, also calls:db:backup-remote
- Exports the remote dev db to the backup folder on Google Cloud Storage (called on everydb:update-local-from-remote
)db:rename-remote-backup-folder
- Renames the remote backup folder (called on everydb:backup-remote
to preserve the previous db backup)
db:backup-local
- Save the local db changes to the disk (overwrites existing)
Debugging
- Find local logs directly in the shell that ran
$ yarn dev
- Find deployed logs here
Deploying
$ firebase use prod
to switch to prod$ yarn deploy
to push your changes live! (Future TODO: auto-deploy functions on Git push)
Secrets management
Secrets are strings that shouldn't be checked into Git (eg API keys, passwords). We store these using environment config on Firebase Functions. Some useful workflows:
- Set a secret:
$ firebase functions:config:set stripe.test_secret="THE-API-KEY"
- Preview all secrets:
$ firebase functions:config:get
- Cache for local dev:
$ firebase functions:config:get > .runtimeconfig.json
