Accessing JSON file content from Firebase storage

I'm currently working on extracting the data from a JSON file stored in my Firebase in order to utilize it for searching within my Google action. So far, I have managed to retrieve the file, but I'm unsure of which method to employ next. I am looking for something akin to a toString() method to transfer the contents of the JSON file into my action.

After scouring through , I am contemplating whether to use get() or createReadStream(), however, there isn't enough information available to determine the best course of action.

const { conversation } = require('@assistant/conversation');
const functions = require('firebase-functions');
const admin = require('firebase-admin');

const defaultApp = admin.initializeApp({
  credential: admin.credential.applicationDefault()
});
const database = admin.firestore();
var storage = defaultApp.storage();
const bucket = storage.bucket('gs://NAME_OF_BUCKET.appspot.com');
const jsonFile = bucket.file('FILE_NAME.json');

I would greatly appreciate any assistance as I've been diligently searching for a solution without luck so far! Thank you!

Answer №1

For this particular situation, you have the option of using either download() or createReadStream(). Depending on the size of the JSON file (if it's relatively small, let's say under 1MB), download() might be the easier choice as it eliminates the need to handle streams. On the other hand, createReadStream() is more suitable for scenarios involving processing large files in chunks, such as when passing it through a compression library before saving it to a disk.

const contents = await jsonFile.download();
console.log(contents);
const parsedContents = JSON.parse(contents);
