About
Firestore Extension wraps the Google Firestore Web API so App Inventor apps can read, write, query, and listen to documents securely. Initialize with API key and project ID, manage collections, merge updates, verify Firebase ID tokens, and register polling listeners to react to data changes instantly.
Features
- Initialize Firestore Web API with API key and project ID
- Add, set, update, and delete documents and collections
- Query collections with where clauses and fetch all documents
- Register polling listeners for modified and removed documents
- Verify Firebase ID tokens to protect backend calls
- Return results as App Inventor lists and dictionaries
- Built with FAST tooling for consistent API surface
