I tried deploying a firebase functions but it keeps failing due to some issue with ESLint. I have also tried googling the answer but everything I am seeing is all Greek to me.
I have also stumbled on this and this answer but it appears they're not applicable to my scenario.
// // Create and Deploy Your First Cloud Functions
// // https://firebase.google.com/docs/functions/write-firebase-functions
//
// exports.helloWorld = functions.https.onRequest((request, response) => {
// response.send("Hello from Firebase!");
// });
//import firebase functions modules
const functions = require("firebase-functions");
//import admin module
const admin = require("firebase-admin");
admin.initializeApp(functions.config().firebase);
// Listens for new messages added to messages/:pushId
exports.pushNotification = functions.database.ref("/Message").onWrite( event => {
// Grab the current value of what was written to the Realtime Database.
var valueObject = event.data.val();
// Log the event
console.log("Push notification event triggered for " + valueObject.title);
//if(valueObject.title != null) {
//valueObject.photoUrl= "Sent you a photo!";
// }
// Create a notification
const payload = {
data: {
body:valueObject.body,
imgUrl: valueObject.imgUrl,
postUrl: valueObject.postUrl,
title: valueObject.title
},
};
//Create an options object that contains the time to live for the notification and the priority
const options = {
priority: "high",
timeToLive: 60 * 60 * 24
};
return admin.messaging().sendToTopic("Posts", payload, options);
});

Please what am I doing wrong?
The only way I can imagine that your project got into this state is if you refused to allow npm to install dependencies at the time of project creation. So when you asks you this:
? Do you want to install dependencies with npm now?
You may have answered 'No'. This would prevent the eslint package from being installed, and you would see that error.
Otherwise, you may have deleted the eslint installed package under node_modules
somehow. You can run npm install
from the functions
folder to recreate everything needed under node_modules
.
