# Cloud Functions for Firebase Sample Library
This repository contains a collection of samples showcasing some typical uses of [Cloud Functions for Firebase](https://firebase.google.com/features/functions).
Samples are available for **Node** (1st and 2nd gen) and **Python** (2nd gen).
> Note: Python support in Cloud Functions for Firebase is a public preview. This means that the functionality might change in backward-incompatible ways. A preview release is not subject to any SLA or deprecation policy and may receive limited or no support.
### What's Cloud Functions for Firebase?
Cloud Functions is a hosted, private, and scalable Node.js environment where you can run JavaScript or Python code. [Cloud Functions for Firebase](https://firebase.google.com/features/functions) integrates the Firebase platform by letting you write code that responds to events and invokes functionality exposed by other Firebase features.
## Prerequisites
> All samples require the Blaze pay-as-you-go billing plan to deploy. Learn more about [pricing](https://firebase.google.com/pricing#cloud-functions).
To learn how to get started with Cloud Functions for Firebase by having a look at the [Getting Started Guide](https://firebase.google.com/docs/functions/get-started), trying the [quickstart samples](/Node/quickstarts) and looking at [the documentation](https://firebase.google.com/docs/functions).

## File: Node/instrument-with-opentelemetry/README.md
# Instrumenting Cloud Functions for Firebase with Open Telemetry
This sample demonstrates instrumenting your Cloud Functions for Firebase using [OpenTelemetry](https://opentelemetry.io).
See Firebase Summit 2022 Talk "Observability in Cloud Functions for Firebase" for motivations and context.
Open Telemetry SDK provides both automatic and manual instrumentation, both of which are demonstrated here. See [OpenTelemetry JS documentations](https://opentelemetry.io/docs/instrumentation/js/) for more information about how to use and configure OpenTelemetry for your javascript project.
## Notable Files
* `./tracing.js`: Initializes OpenTelemetry SDK to automatically instrument HTTP/GRPC/Express modules and export the generated traces to Google Cloud Trace.
* `./.env`: Configures `NODE_OPTIONS` to preload the `tracing.js` module. This is important because OpenTelemtry SDK works by monkey-patching instrumented modules and must run first before other module is loaded.
* `./index.js`: Includes sample code for generating custom spans using the OpenTelemetry API. e.g.:
```js
const opentelemetry = require('@opentelemetry/api');
const tracer = opentelemetry.trace.getTracer();
await tracer.startActiveSpan("calculatePrice", async (span) => {
totalUsd = await calculatePrice(productIds);
span.end();
});
```
## Deploy and test
1. Deploy your function using firebase deploy --only functions
2. Seed Firestore with mock data.
3. Send callable request to the deployed function, e.g.:
```
$ curl -X POST -H "content-type: application/json" https:// -d '{ "data": ... }'
```

## File: Node/fcm-notifications/README.md
# Send Firebase Cloud Messaging notifications for new followers.
This sample demonstrates how to send a Firebase Cloud Messaging (FCM) notification from a Realtime Database triggered Function. The sample also features a Web UI to experience the FCM notification.
## Functions Code
See file [functions/index.js](functions/index.js) for the code.
Sending the notification is done using the [Firebase Admin SDK](https://www.npmjs.com/package/firebase-admin). The Web client writes the individual device tokens to the realtime database which the Function uses to send the notification.
The dependencies are listed in [functions/package.json](functions/package.json).
## Sample Database Structure
Users sign into the app and are requested to enable notifications on their browsers. If they successfully enable notifications the device token is saved into the datastore under `/users/$uid/notificationTokens`.:
```
/functions-project-12345
/users
/Uid-12345
displayName: "Bob Dole"
/notificationTokens
1234567890: true
photoURL: "https://lh3.googleusercontent.com/..."
```
If a user starts following another user we'll write to `/followers/$followedUid/$followerUid`:
```
/functions-project-12345
/followers
/followedUid-12345
followerUid-67890: true
/users
/Uid-12345
displayName: "Bob Dole"
/notificationTokens
1234567890: true
photoURL: "https://lh3.googleusercontent.com/..."
```
## Trigger rules
The function triggers every time the value of a follow flag changes at `/followers/$followedUid/$followerUid`.
## Deploy and test
This sample comes with a web-based UI for testing the function. To test it out:
1. Set up your Firebase project:
1. [Create a Firebase project](https://firebase.google.com/docs/web/setup/#create-firebase-project)
1. [Register your web app with Firebase](https://firebase.google.com/docs/web/setup/#register-app)
1. Enable **Google Provider** in the [Auth section](https://console.firebase.google.com/project/_/authentication/providers)
1. Clone or download this repo and open the `fcm-notification` directory.
1. You must have the Firebase CLI installed. If you don't have it install it with `npm install firebase-tools` and then configure it with `firebase login`.
1. Configure the CLI locally by using `firebase use --add` and select your project in the list.
1. Install dependencies locally by running: `cd functions; npm install; cd -`
1. Deploy your project using `firebase deploy`
1. Open the app using `firebase open hosting:site`, this will open a browser.
1. Start following a user, this will send a notification to them.

## File: Node/delete-unused-accounts-cron/README.md
# Periodically delete unused accounts
This sample demonstrates how to delete the accounts of users who have not signed-in in the last month.
## Functions Code
See the file [functions/index.js](functions/index.js) for the code.
**Note:** This function uses Cloud Scheduler, which can have associated costs. Your project must be on the Blaze payment plan as these features require billing information. See the [Cloud Scheduler pricing page](https://cloud.google.com/scheduler/pricing) for more information.
The dependencies are listed in [functions/package.json](functions/package.json).
## Deploy and test
To set up the sample:
- Create a Firebase Project using the [Firebase Developer Console](https://console.firebase.google.com)
- Download this sample e.g. `git clone https://github.com/firebase/functions-samples`
- Enter the sample directory `cd functions-samples/2nd-gen/delete-unused-accounts-cron`
- Setup the sample with your project `firebase use --add` and follow the instructions.
- Install node dependencies of your Functions `cd functions; npm install; cd -`
- Deploy your project using `firebase deploy`.
- The Cloud Scheduler job should then run once a day and delete any inactive users. You can manually run the task by [navigating to Cloud Scheduler in the Google Cloud Platform Console](https://console.cloud.google.com/cloudscheduler).

## File: Node/call-vertex-remote-config-server/client/README.md
Test client for call-vertex-remote-config-server
================================================
Introduction
------------
This is a basic web app that calls the `callVertexWithRC` function. The
function uses values stored in Remote Config server templates with
the Firebase Admin SDK to dynamically update Vertex AI Gemini API
parameters. Access is controlled using Firebase App Check.
- [Read more about Remote Config for servers](https://firebase.google.com/docs/remote-config/server).
- [Read more about App Check](https://firebase.google.com/docs/app-check).
- [Read more about the Vertex AI Node.js Client library](https://cloud.google.com/nodejs/docs/reference/aiplatform/latest).
Important: Vertex AI and Cloud Functions require a billing account. Review
[Vertex AI pricing](https://cloud.google.com/vertex-ai/pricing) and
[Firebase pricing](https://firebase.google.com/pricing) before running
this function. If you're new to Firebase and Google Cloud, check to see if
you're eligible for a
[$300 credit](https://firebase.google.com/support/faq#pricing-free-trial) and
a Free Trial Cloud Billing account.
Get started
---------------
1. Create a [Firebase project and register a web app](https://firebase.google.com/docs/web/setup#create-firebase-project-and-app).
2. [Create a ReCAPTCHA Enterprise key](https://firebase.google.com/docs/app-check/web/recaptcha-enterprise-provider#project-setup)
in the same project.
3. [Enable App Check](https://firebase.google.com/docs/app-check/web/recaptcha-enterprise-provider)
in the Firebase console with the ReCAPTCHA Enterprise site key you created.
4. Copy your Firebase project config and your ReCAPTCHA Enterprise site key
into the appropriate places in `config.ts` in this directory.
5. In this directory, run `npm install`.
6. Set up and deploy the function as described in [../README.md](../README.md).
7. In this directory, run `npm run dev` to run the client.
To run this app against the `callVertexWithRC` function running in the Firebase
emulator, ensure that `testMode`in `main.ts` is set to `true`. Before testing
with a deployed (i.e., not emulated) function, set `testMode` to `false`.
TIP: You can build the client and deploy to Firebase Hosting by running
`npm run build` from the `client` directory. Hosting deliverables are
generated and saved in `client/dist` and you can then deploy to
the emulator or Firebase Hosting from the parent directory. We recommend
deploying to the emulator first--you can use the following command to
deploy the function and web client simultaneously:
firebase serve --only functions,hosting

## File: Node/call-vertex-remote-config-server/README.md
Call the Vertex AI Gemini API with Remote Config and App Check
==============================================================
Introduction
------------
This is a sample callable function that authenticates clients with App
Check and then sends queries to Gemini using the Vertex AI Gemini API. Vertex
AI model parameters (including the model itself) are controlled by
Remote Config server features included in the Firebase Admin SDK for
Node.js.
Use the web client provided in `client/` to test the function.
- [Read more about Remote Config for servers](https://firebase.google.com/docs/remote-config/server).
- [Read more about App Check](https://firebase.google.com/docs/app-check).
- [Read more about the Vertex AI Node.js Client library](https://cloud.google.com/nodejs/docs/reference/aiplatform/latest).
Important: Vertex AI and Cloud Functions require a billing account. Review
[Vertex AI pricing](https://cloud.google.com/vertex-ai/pricing) and
[Firebase pricing](https://firebase.google.com/pricing) before running
this function. If you're new to Firebase and Google Cloud, check to see if
you're eligible for a
[$300 credit](https://firebase.google.com/support/faq#pricing-free-trial) and
a Free Trial Cloud Billing account.
Get Started
---------------
1. Follow the instructions in client/README.md to create a Firebase project,
enable ReCAPTCHA Enterprise, enable and enforce Firebase App Check, and add
your Firebase config and ReCAPTCHA Enterprise key to the client config.
2. Enable [recommended Vertex AI APIs](https://console.cloud.google.com/vertex-ai).
3. Configure a Remote Config server template on the Firebase console. Use the template
described in
[Use server side Remote Config with Cloud Functions and Vertex
AI](https://firebase.google.com/docs/remote-config/solution-server#implementation-create-template),
which contains all of the parameters used in this function sample.
4. Install dependencies: `cd functions && npm install`
5. If you haven't already done so, install firebase-tools:
`npm i firebase-tools@latest`
6. Log into Firebase:
`firebase login`
7. Deploy the function. We recommend testing in the
[Firebase emulator](https://firebase.google.com/docs/remote-config/solution-server#implementation-deploy-and-test-in-emulator):
`firebase emulators:start`
8. If testing in the emulator, verify that `testMode` is set to `true` in
`client/main.ts`, then start the client:
`cd client && npm run dev`
TIP: If you're using the emulator, you can deploy both the function and hosting
to the emulator. From the `client` directory, run `npm run build`.
Then, from the parent directory, run `firebase server --only functions,hosting`.
Open http://localhost:5000 to access and test the web client's connection
to the `callVertexWithRC` function.
0. Open the [client app in a browser](http://localhost:5173) and enter a
prompt. To access the Vertex AI Gemini API, make sure that you have

## File: Node/app-distribution-feedback-to-jira/README.md
# Send in-app feedback to Jira
This [code](functions/index.js) demonstrates how to use a Firebase Cloud Function triggered by an
[in-app feedback Firebase Alert from App Distribution](https://firebase.google.com/docs/functions/beta/reference/firebase-functions.alerts.appdistribution.inappfeedbackpayload),
and stores the feedback details (including screenshot) in Jira.
You can customize this code to work with your own Jira configuration (eg on-premise support, custom issue types, etc).
## Quickstart
This sample code uses Jira's built-in APIs to create issues for in-app tester feedback. For simplicity it uses [basic authorization](https://developer.atlassian.com/cloud/jira/platform/basic-auth-for-rest-apis/).
1. [Generate an API token](https://id.atlassian.com/manage-profile/security/api-tokens) via your Jira profile.
Note: If the tester who files feedback does not have a Jira account, the user who generates this token will be marked as the issue's reporter.
2. This [code](functions/index.js) uses [parameterized configuration](https://firebase.google.com/docs/functions/config-env#params) to prompt for the required configuratio. To start the process, run:
```bash
$ firebase deploy
```
This will store the `API_TOKEN` using [Google Cloud Secret Manager](https://cloud.google.com/secret-manager) and the remaining settings in an `.env` file which will contain the following variables, customized to your Jira project:
```bash
JIRA_URI=""
PROJECT_KEY=""
ISSUE_TYPE_ID=""
ISSUE_LABEL="
