Deploying Firebase Cloud Function

Purpose: We used cloud function for sending push notification for user based on some triggers like new messages, group creation..etc

Let's do setup.

Before doing firebase setup, we need to install firebase tools on your machine. To do that, please execute

npm install -g firebase-tools

Step 1: Create new project & login to firebase

mkdir fcf
cd fcf
firebase login
firebase init functions

It might asks your few questions, please answer as followed

• Choose your firebase project
• Language: JavaScript
• EsLint: No
• Npm install: Yes

Step 2: Installing Required dependencies

Then, we need to follow these steps,

cd functions
npm install --save firebase-admin
npm install --save firebase-functions
npm install --save request

Step 3:

After installation, we need to replace newly created index.js file with downloaded (purchased) index.js;

Step 4: Updating Files

• Rename downloaded files to service-account-key.json
• Copy your service-account-key.json to fcf/functions/
• Open fcf/functions/index.js with any text editor & Update your databaseURL

Step 5: Deploying FCF

cd ..
firebase deploy --only functions

Note: You must be inside fcf/ (not inside fcf/functions) folder for deploying.

Step 6: Updating customToken URL

After deployment, you can see CustomTokenURL on console, which you need to update with your project/src/settings.ts
