Firebase cloud function for file upload

Question

I have this cloud function that I wrote to upload file to google cloud storage:

const gcs = require(\'@google-cloud/storage\')({keyFilename:\'2fe4e3d2bfdc.js         


        

Answer 1

I managed this by downloading the file to the tmp instead.

You will need:

const mkdirp = require('mkdirp-promise');

Then, inside onChange. I created tempLocalDir like so:

const LOCAL_TMP_FOLDER = '/tmp/';
const fileDir = (the name of the file); //whatever method you choose to do this
const tempLocalDir = `${LOCAL_TMP_FOLDER}${fileDir}`;

Then I use mkdirp to make the temp directory

return mkdirp(tempLocalDir).then(() => {
// Then Download file from bucket.
const bucket = gcs.bucket(object.bucket);
return bucket.file(filePath).download({
  destination: tempLocalFile
}).then(() => {
    console.log('The file has been downloaded to', tempLocalFile);
    //Here I have some code that converts images then returns the converted image
    //Then I use
    return bucket.upload((the converted image), {
        destination: (a file path in your database)
    }).then(() => {
        console.log('JPEG image uploaded to Storage at', filePath);
    })//You can perform more actions of end the promise here

I think my code achieves that you were trying to accomplish. I hope this helps; I can offer more code if necessary.
