firebase Push notification from custom server Using Admin SDK(Node js)
Example
At first initilize the firebase sdk and admin SDK
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp({
credential: admin.credential.cert({
//your admin credential certificate generated from the console. Follow this [link][1].
}),
databaseURL: "https:///<PROJECT_NAME>.firebaseio.com"
});
Create a payload JSON string as in the first example.
var payload = {
notification: {
title: "Title of the notification,
body: "Body of the notification",
},
data:{
//required key value pair
}
};
Then call different send methods to send the notification.
For Topic
admin.messaging().sendToTopic("/topic/", payload)
.then(function(response) {
console.log("Successfully sent message:", response);
})
.catch(function(error) {
console.log("Error sending message:", error);
});
});
For device
admin.messaging().sendToDevice(token, payload).then(response=>{
response.results.forEach((result, index) => {
const error = result.error;
if (error) {
console.error('Failure sending notification to', tokens, error);
} else{
console.log('Sucessfully sent to '+tokens);
}
});
