Firestore backend for Storex.

Usage

$ npm install @worldbrain/storex @worldbrain/storex-backend-firestore

See main Storex repo for futher docs

Limitations

• You can only sort by one field, and that field must be the one you're filtering by (Firestore docs)
• You cannot use the $ne operator (Firestore docs)
• No logical ORs (Firestore docs)
• Skipping the first X items in an ordered retrieve is done client-side, so it is recommended to increase the lower limit of your resultset instead (findObjects({foo: {$gt: X + Y}}) rather than findObjects({foo: {$gt: X}, {skip: Y}}))

TBD

• Automatic security rule generation
• Ability to easily move StorageModules to Firebase Functions
• Back-end agnostic automatic processes, which whould be Firebase Functions listening to certain queries in this backend
• Subcollection support (after investigations on real-world performance benefits)
• Media field support integrating with Firebase Cloud Storage

Note: Firebase Realtime database support should be a separate back-end

Development

Create a new Firebase project for unit testing, and create the file <this-repo>/private/firebase.json (in .gitgnore so it doesn't accidentally go public) with the following contents:

{
    "apiKey": "xxxx",
    "authDomain": "xxx.firebaseapp.com",
    "databaseURL": "https://xxxx.firebaseio.com",
    "projectId": "xxxxx",
    "storageBucket": "xxxx.appspot.com",
    "messagingSenderId": "xxxxx"
}

Then continuously run the tests while developing:

$ npm run test:watch
