Setup Cloud Functions support push notification on Mobile App
Refer tutorial from https://firebase.google.com/docs/functions/get-started
1. Set up Node.js and the Firebase CLI
You'll need a Node.js environment to write functions, and you'll need the Firebase CLI (which also requires Node.js and npm) to deploy functions to the Cloud Functions runtime. From among the supported Node.js versions available for Cloud Functions, we strongly recommend Node.js 8 for getting started. For installing Node.js and npm, Node Version Manager is recommended.
Once you have Node.js and npm installed, install the Firebase CLI via npm:
| Code Block |
|---|
npm install -g firebase-tools |
2. Initialize Firebase SDK for Cloud Functions
...
Structure of your project
| Code Block |
|---|
myproject
+- .firebaserc # Hidden file that helps you quickly switch between
| # projects with `firebase use`
|
+- firebase.json # Describes properties for your project
|
+- functions/ # Directory containing all your functions code
|
+- .eslintrc.json # Optional file containing rules for JavaScript linting.
|
+- package.json # npm package file describing your Cloud Functions code
|
+- index.js # main source file for your Cloud Functions code
|
+- node_modules/ # directory where your dependencies (declared in
# package.json) are installed
|
Edit package.json file, add new module request to dependencies object
| Code Block |
|---|
{
"name": "functions",
....
"engines": {
"node": "8"
},
"dependencies": {
.....
"request": "^2.88.0"
},
....
}
|
Then run cd functions/ && npm install (from project folder) to update project modules.
