I wrote function which work on firebase function and which take an answer on request if request come from the dialog console or the Google Assistant emulator. But if I ask from Telegram this function doesn't work.
Answer like Say that one more time? or if I filled the form Responses on web I have this response.
How connect firebase function with Telegram?
'use strict';
const {
dialogflow,
Permission,
Suggestions,
BasicCard,
} = require('actions-on-google');
const firebase = require('firebase');
const functions = require('firebase-functions');
const app = dialogflow({debug: true});
app.intent('simple word', (conv) => {
conv.ask(`it's ok`);
});
exports.dialogflowFirebaseFulfillment = functions.https.onRequest(app);
The problems is that you're using the actions-on-google library, which is specifically designed to send results to the Assistant.
If you want to be able to send results to Telegram, you need to use the dialogflow-fulfillment library, which handles things slightly differently.

I am working in an android app project for my college minor project. Everything is working but now i want to add a notification feature, i.e whenever a admin posts a notice every user subscriber to that topic gets notification, i tried to follow different tutorials and documents but since i have no programming background in js/nodejs/php i couldn't understand the cloud functions.
Can anyone write the functions or lead me to the answer?
i want the function to be triggered when a new notice is added inside /Notice and send notification to all users subscribe to Notice..
i wrote the following code, after some study,
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotices =
functions.database.ref('/Notices/{nID}').onCreate((event) => {const data =
event.data;
if(!data.changed()){
console.log('Nothing changed');
return;
}else{
console.log(data.val());
}
const payLoad = {
notification:{
title: 'Message received',
body: 'You received a new message',
sound: "default"
}
};
const options = {
priority: "high",
timeToLive: 60*60*2
};
return admin.messaging().sendToTopic("bctb", payLoad, options);});
and got the error in console of firebase,what am i doing wrong here,
TypeError: Cannot read property 'changed' of undefined

Since you are not familiar with the Firebase Cloud Functions, I recommend you first go through official docs here, because without going through the basics you won't understand how they work and then go through Firebase Cloud Messaging (FCM) docs here. Once you get to know how both the service work it'll be a lot easier for you to understand and write your own cloud function. For your ease here is how your function should be like.
You can do this by simply creating an onCreate trigger function. So it will look something like:
exports.SendNotification = functions.database.ref('/Notice/{nid}')
.onCreate((snapshot, context) => {
//Your notification code here
}
Here nid is the notice id that is just created. Firebase will automatically get this id. And for sending the notification you can use Firebase cloud messaging (FCM). In this cloud function you can create a notification payload.
//send notification
const payload = {
data:{
title: "New notice has been added!",
}
};
Now you can send this notification to the app using:
admin.messaging().sendToDevice(instID, payload);
Here, instID is the instance ID. Each app installed has a unique instance ID. For sending to multiple devices you'll have to wrap the code line above in an loop to send notifications to all of the subscribed users. For this you need instance IDs of all the subscribed users.

Best of luck.
I want to integrate my Firestore using data I got in my Dialogflow project.
I was searching in the net and I found just some random things.
I wrote some console.log inside, because I want to understand how does it work, but nothing seems happening, and I don't even know where I can find my logs.
Here it is my index.js Dialogflow code:
'use strict';
// Import the Dialogflow module from the Actions on Google client library.
//const {dialogflow} = require('actions-on-google');
const {dialogflow,Permission,SimpleResponse,Image,Carousel,BrowseCarousel,BasicCard,Button,BrowseCarouselItem,Suggestions,List,MediaObject} = require('actions-on-google');
// Import the firebase-functions package for deployment.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
// Instantiate the Dialogflow client.
const app = dialogflow({debug: true});
admin.initializeApp(functions.config().firebase);
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
console.log('Request headers: ');
});
Is there something I am missing?
Sorry, but it's my first time using Dialogflow.
Since you're using the built-in editor, your logs will be in the Firebase Cloud Functions logs section. To get there
Go to https://console.firebase.google.com/ and select your project.
Select "Functions" on the left navigation.
Select "Logs" in the navigation towards the top.
I'd like to integrate my firebase project with some 3rd party API's, like the twitter API.
3rd party API
The following code will listen to new tweets containing the certain text 'little rocket man':
var Twitter = require('twitter');
// setup new twitter client
var client = new Twitter({
consumer_key: '',
consumer_secret: '',
access_token_key: '',
access_token_secret: ''
});
// open new twitter stream
let stream = this.client.stream('statuses/filter', { track: 'little rocket man' });
stream.on('data', (event: any) => {
let tweetText = event && event.text; // this should be written to the firebase db
});
Firebase Cloud Functions
The following firebase cloud functions listens to incoming HTTP GET requests on a specific route and saves data back to the firebase db:
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin'; // Firebase Admin SDK
admin.initializeApp(functions.config().firebase);
// this example uses a HTTP trigger, but how can I trigger it whenever new tweets containint 'little rocket man' are detected??
exports.addMessage = functions.https.onRequest((req, res) => {
const original = req.query.text;
admin.database().ref('/messages').push({original: original}).then(snapshot => {
res.redirect(303, snapshot.ref);
});
});
Question
How can I write the tweets I'm recieving from the twitter client back to the firebase db? If possible, I'd like to run all the code on firebase cloud functions.
Disclaimer:
I'm new to firebase and although googling around for a few hours I wasn't able to find the solution to my problem on the net. I'd like to apologize in advance, should I have overseen it.
You can't use streaming APIs like this in Cloud Functions. A function may only respond to some distinct event, such as an HTTP request, or some change in your database. Functions can't run indefinitely.
If you want to collect tweets that match some query into your database, you can use IFTTT to periodically send them to a function as they become available. I recently finished a small project that does exactly that.
I'm trying to get my Cloud Functions for Firebase to call a simple web app deployed using Google Apps Script. Can someone please point to any example or help figure out whats the reason for the error in my code below. Really appreciate your help.
--
I've created a simple webapp with Google Apps Script.
function doGet() {
return ContentService.createTextOutput('Hello world');
}
And I'm calling this using request-promise within my Firebase Cloud Function. I've tried to be as close to the Google Translate example given for Cloud Functions. However, I get the following error when the Cloud Function is invoked.
RequestError: Error: getaddrinfo ENOTFOUND script.google.com
script.google.com:443
Here is my Cloud Function code -
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const request = require('request-promise');
exports.makeUppercase =
functions.database.ref('/users/{userid}/logs/{logid}/mykey')
.onWrite(event => {
var url = `https://script.google.com/macros/s/.../exec`;
var retstr = request(url, {resolveWithFullResponse: true}).then(
response => {
if (response.statusCode === 200) {
const data = response.body;
return event.data.ref.parent.child('uppercase').set(data);
}
throw response.body;
});
});
Thanks in advance,
Regards
Rahul
I had the same issue and found this answer(https://stackoverflow.com/a/42775841).
Seems like calling Google Apps Script is considered external.
I will be implementing an elastic search index alongside my firebase application so that it can better support ad-hoc full text searches and geo searches. Thus, I need to sync firebase data to the elastic search index and all the examples require a server process that listens for firebase events.
e.g. https://github.com/firebase/flashlight
However, it would be great if I can just have a google cloud function triggered by an insert in a firebase node. I see that google cloud functions has various triggers: pub sub, storage and direct... can any of these bridge to a firebase node event without an intermediate server?

We just released Cloud Functions for Firebase. This allows you to run JavaScript functions on Google's servers in response to Firebase events (such as database changes, users signing in and much more).
I believe Cloud Functions for Firebase are what you are looking for.
Here are a few links:
Official Documentation
Intro video
Google Cloud Functions and Firebase (Google Cloud Next '17)
yes, you can trigger a Google Cloud Functions via firebase event without a server.
As per documents,Firebase allows for example you can send notifications using a cloud function when a user write into firebase database.
For that, I had to write a javascript as below
'use strict';
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.sendNotification = functions.database.ref('/articles/{articleId}')
.onWrite(event => {
// Grab the current value of what was written to the Realtime Database.
var eventSnapshot = event.data;
var str1 = "Author is ";
var str = str1.concat(eventSnapshot.child("author").val());
console.log(str);
var topic = "android";
var payload = {
data: {
title: eventSnapshot.child("title").val(),
author: eventSnapshot.child("author").val()
}
};
// Send a message to devices subscribed to the provided topic.
return admin.messaging().sendToTopic(topic, payload)
.then(function (response) {
// See the MessagingTopicResponse reference documentation for the
// contents of response.
console.log("Successfully sent message:", response);
})
.catch(function (error) {
console.log("Error sending message:", error);
});
});
