I use a cloud function as a webhook receiver, so every time I get a webhook I want to update firestore with some data for example. I don't get how to use firestore in my clound function.
I tried this:
const admin = require("firebase-admin");
...
admin.initializeApp();
res.send(admin.database().ref("/tmp_list/1uMW9ED3YGMfERHZiKJc").get());
All do not seem to be able to initilise this. I also tried:
admin.initializeApp(functions.config().firebase);
As explained in the documentation, the following should do the trick:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
Then, to interact with the Realtime Database in an HTTPS Cloud Function you should do along the following lines:
exports.date = functions.https.onRequest(async (req, res) => {
const db = admin.database();
const dataSnapshot = await db.ref("tmp_list/1uMW9ED3YGMfERHZiKJc").get();
const data = dataSnapshot.val();
// ...
res.send(data);
});
Since you tagged your question as google-cloud-firestore, note that in order to interact with Firestore in an HTTPS Cloud Function you should do as follows:
exports.date = functions.https.onRequest(async (req, res) => {
const db = admin.firestore();
const docSnapshot = await db.doc("tmp_list/1uMW9ED3YGMfERHZiKJc").get();
const data = docSnapshot.data();
// ...
res.send(...)
});
