how to get all documents from Firestore and make a loop (Cloud Functions)-CodePudding

I am trying to access data in my Firestore database using cloud function using Javascript I need to loop on all the documents I have (I have 7 documents), but it only returns the first document and prints it in the logs, and I don't know why. this is my code

const functions = require("firebase-functions");
const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

// Create and deploy your first functions
// https://firebase.google.com/docs/functions/get-started

exports.helloWorld = functions.https.onRequest(async (request, response) => {
  functions.logger.info("Hello logs", {structuredData: true});
  

  //loop on the document
  const facultyRef = await admin.firestore().collection('faculty').get().then((querySnapshot) => {
    querySnapshot.forEach((doc) => {
        response.send("Hello Firebase");
        //print the doc id in the logs
        functions.logger.info(doc.id);
    });
});

});

Note: It print 'Hello Firebase' in the page, and print 'hello logs' and only the first document Id in the logs

CodePudding user response：

By doing response.send() you are actually terminating your Cloud Function, see the documentation.

If you want to log all the doc IDs, do as follows:

exports.helloWorld = functions.https.onRequest(async (request, response) => {
    functions.logger.info("Hello logs", { structuredData: true });

    const facultyQuerySnapshot = await admin.firestore().collection('faculty').get();

    facultyQuerySnapshot.forEach((doc) => {
        //print the doc id in the logs
        functions.logger.info(doc.id);
    });

    // We terminate the Function AFTER the loop has completed
    response.send("Hello Firebase");

});
