问题 This question already has answers here : Should firebase auth onCreate trigger have more data? (1 answer) Firebase Auth+Functions | create user with displayName (1 answer) Closed 8 months ago .

问题 I am new to Firestore cloud functions, and trying to run a simple function that triggers onWrite() in one collection and based on that, updates value in different one. I am hitting roadblock where value of variable (const array actually), is not recognized inside the ...get().then(snapshot) => {} method. As I understand the outer variable's scope should be inside as well, shouldn't it? What am I doing wrong? Research on this topic led me to concept of Promises, and I tried creating promise

问题 I am currently looking for the best way to create a user with additional information in a cloud function. The obvious possibility seems to create a trigger which creates a user document: functions.auth.user().onCreate((user) => { /* Create user document in firestore with base information*/ }); And afterwards add the information to the created document. (Handle the promise) But one way or another I don't feel really satisfied with this solution. I would rather do all this stuff in one go. Does

问题 I have some large binary files stored in Google Cloud Storage that require byte by byte processing. I would like to do this processing using a Cloud Function, but this would require streaming the binary data through the cloud function. Does anybody have any idea how to do this.

问题 I upload 10 files every day at 11 p.m with a Cron Job to a bucket on GCS. Each file is a .csv with a size from 2 to 30 KB . The file name is always YYYY-MM-DD-ID.csv A Cloud Function is called everytime I am uploading a file into that bucket to send those .csv files to BigQuery. The trigger type is Cloud Storage on finalise/create events. My issue is the following: On BigQuery, each value for each row/columns is multiplied by a multiple. Sometimes it's 1 (so the value is the same), often 2

问题 We are designing out our listening side of Google PubSub and will be using Google Functions for this. There are two choices, push and a backend function. Push using Http and will push messages to the function. backend function uses triggering to invoke the function. Where we are having trouble is deciding which approach may be better for our application. We have not been able to find a list of differences between these two methods within the Google documentation. Some things we have noticed

问题 I am a junior developer and I was in charge of implementing the Facebook API to an existing project. However, the business team figured out that the Google Analytics results displayed on BigQuery are wrong. They asked me to fix it. This is the architecture: What I have done is: On BigQuery, checking how close/far are the results from Google Analytics.
