How to start using rxdb CDN


// Include RxDB and RxJS libraries
const { RxDB, RxMongo } = require('rxdb');
const Rx = require('rxjs');

// Initialize RxDB with RxMongo adapter
RxDB.plugin(RxMongo);
const db = new RxDB({ url: 'localhost:27017/mydb' });

// Define a schema for a simple document
const mySchema = {
  title: 'MyDocument',
  properties: {
    id: 'number',
    name: 'string',
  },
};

// Create a model based on the schema
const MyDocument = db.model(mySchema);

// Create a new document
const newDocument$ = Rx.Observable.from({ name: 'New Document' }).pipe(
  MyDocument.create(),
);

// Save the document to the database
newDocument$.subscribe((doc) => {
  console.log('Document saved:', doc.toJSON());
});

// Update the document
const updateDocument$ = Rx.Observable.interval(2000).pipe(
  map(() => MyDocument.update({ id: 1 }, { $set: { name: 'Updated Document' } })),
);

// Subscribe to updates
updateDocument$.subscribe(() => {
  MyDocument.findOne({ id: 1 }).subscribe((doc) => {
    console.log('Document updated:', doc.toJSON());
  });
});

// Cleanup
db.destroy().subscribe();
