For anyone having issues installing the firebase and firebase-admin packages you can run the following commands to update them to the latest version:
1. npm install -g npm-check-updates
2. npm-check-updates -u
3. npm install

Thanks for the great video btw, and very cool that you launched FireKit!

Thank you! You can delete the databaseURL line, no need to include in latest version.

If you're getting an error: 'Value for argument "documentPath" is not a valid resource path. Path must be a non-empty string.' it's because you need to either include "ItemID": "<desired doc name>" in each object or you can update lines 27 & 28 to the below to have firebase auto-generate the id for you.

.doc()
.create(obj)

Thanks for the solution. Very useful to me too...

I also made a Readme file for some error encountered( STEP 3 mainly) :

This project is for uploading json files to Firebase's Coud Firestore database.

1. Add all your .json files to the files folder

2. open terminal and run : npm install firebase firebase-admin

3. Update the part : doc(obj.itemID) to .doc(obj.itemID || obj.<YOUR_DOCUMENT_IDS) i.e Update this section to match the ID of documents within your collection, The ID will be used to create individual documents within your collection

4. open terminal and run : node uploader.js

NB: this script assumes your collections to be uploaded are not nested.

Great stuff! This is really helpful. I read an article on this subject on "medium", but it was only half of the info needed. Thanx for this.

So glad I found this before I started coding a solution on my own lol. Thanks!

my one didn't work at first but i got it working, it really depends on what type of json file that you're working with my one had object but I modified it a little bit and the main uploader.js file code and wala it worked like a charm! Here's a tip below :
menu.forEach(function (obj) {
firestore
.collection('myCollection') // this is the main collection name
.doc() // if you want auto id keep it like this (empty)
.set(obj)
.then(function (docRef) {
console.log("Document written");
})
.catch(function (error) {
console.error("Error adding document: ", error);
});
});

this code won't work if you don't have an array because " menu.forEach(function (obj) { " is an array fucntion which will work only on arrays
Best of luck !

Thanks for posting this helpful. FYI for people > code has some assumptions like you aren't storing any other directories or non json files within the "files" directory.

There's no database URL on firestore. Where can I find it?

Awesome. Just used it, and had to make changes there and there docID and it worked like a charm!

This is a great video! Thanks so much. Would love to see more stuff like this! Great work!

Great tutorial, a life saver for me. One day I will try to write something like your script in Dart.

If you want to get the document ID before it was added:

menu.forEach(function(obj) {
var newDocRef =
obj.itemId= newDocRef.id;
newDocRef.set(obj)
.then(function(docRef) {
console.log("Document written");
})
.catch(function(error) {
console.error("Error adding document: ", error);
});
});

Goodluck and you're doing great.
