How to import CSV or JSON to firebase cloud firestore

Question

Is there a way to import CSV or JSON to firebase cloud firestore like in firebase realtime database?

Answer 1

I used the General Solution provided by Maciej Caputa. Thank you (:

Here are a few hints. Assuming that you have an Ionic Firebase application installed with the required Firebase node modules in the functions folder inside that solution. This is a standard Ionic Firebase install. I created an import folder to hold the script and data at the same level.

Folder Hierarchy

myIonicApp
    functions
        node_modules
            firebase-admin
ImportFolder
    script.js
    FirebaseIonicTest-a1b2c3d4e5.json
    fileToImport.json

Script Parameters

const admin = require('../myIonicApp/functions/node_modules/firebase-admin'); //path to firebase-admin module
const serviceAccount = require("./FirebaseTest-xxxxxxxxxx.json"); //service account key file

admin.initializeApp({
  credential: admin.credential.cert(serviceAccount),
  databaseURL: "https://fir-test-xxxxxx.firebaseio.com" //Your domain from the hosting tab
});

Creating the Service Account Key File

• In the Firebase console for your project, next to the Project Overwiew item, click on the gear icon and select Users and permissions
• At the bottom of the screen, click Advanced permission settings

• This opens another tab for the Google Cloud Platform Console
• On the left select the Service Accounts item
• Create a Service Account for an existing Service Account

I simply added a key to the App Engine default service account

The Create key function will offer to download the key to a JSON file

JSON Data Structure

To use the script provided, the data structure must be as follows:

{
  "myCollection" : {
    "UniqueKey1" : {
      "field1" : "foo",
      "field2" : "bar"
    },{
    "UniqueKey2" : {
      "field1" : "fog",
      "field2" : "buzz"
    }...
}
