algolia-firebase-cloud-functions

This is an example of keeping a Firebase Database in-sync with an Algolia index using Google Cloud Functions

Deploy Google Cloud Function

How to use:

1. Install firebase cli (requires npm and node.js, more instructions here: https://firebase.google.com/docs/functions/get-started)

$ npm install -g firebase-tools

2. Install node packages

$ npm install

3. add your algolia credentials to your firebase function. This will save the credentials as environment variables that can be used in the function

$ firebase functions:config:set algolia.app_id="APPID" algolia.api_key="API_KEY"

4. edit index.js with the Algolia index name you would like to publish to and also the url in firebase you would like to monitor (line 7 and 9)

5. Deploy the firebase functions

$ firebase deploy --only functions

Backfill your data

In some cases you might already have existing data in firebase that you would like to sync to algolia or would like to re-sync your database. In this case I provided a backfill.js file that will transfer all the current data to algolia.

How to use:

1. Open backfill.js
2. Fill in the following values:

• ALGOLIA_APP_ID
• ALGOLIA_API_KEY
• ALGOLIA_INDEX_NAME
• path/to/service/account.json (these are your credntials to your firebase database. You can generate a private key by going to Project Settings -> Service Accounts -> Firebase Admin SDK) on the firebase webpage
• FIREBASE_URL
• FIREBASE_ITEM_NAME

3. run the script by doing $ node backfill.js
