Usage

Note Android min-sdk is 19

import { Couchbase } from 'nativescript-couchbase-plugin';
const database = new Couchbase('my-database');
 
const documentId = database.createDocument({
    "firstname": "O",
    "lastname": "Fortune",
    "address": {
        "country": "Trinidad and Tobago"
    },
    "twitter": "https://www.twitter.com/triniwiz"
});
 
const person = database.getDocument(documentId);
 
 
database.updateDocument(documentId, {
    "firstname": "Osei",
    "lastname": "Fortune",
    "twitter": "https://www.twitter.com/triniwiz"
});
 
const isDeleted = database.deleteDocument(documentId);

Synchronization with Couchbase Sync Gateway and Couchbase Server

import { Couchbase } from 'nativescript-couchbase-plugin';
const database = new Couchbase('my-database');
 
const push = database.createPushReplication(
  'ws://sync-gateway-host:4984/my-database'
);
push.setUserNameAndPassword("user","password");
const pull = database.createPullReplication(
  'ws://sync-gateway-host:4984/my-database'
);
pull.setSessionId("SomeId");
pull.setSessionIdAndCookieName("SomeId","SomeCookieName");
 
push.setContinuous(true);
pull.setContinuous(true);
push.start();
pull.start();

Listening for Changes

database.addDatabaseChangeListener(function(changes) {
  for (var i = 0; i < changes.length; i++) {
    const documentId = changes[i];
    console.log(documentId);
  }
});

Query

const results = database.query({
  select: [], // Leave empty to query for all
  from: 'otherDatabaseName', // Omit or set null to use current db
  where: [{ property: 'firstName', comparison: 'equalTo', value: 'Osei' }],
  order: [{ property: 'firstName', direction: 'desc' }],
  limit: 2
});

Transactions

Using the method inBatch to run group of database operations in a batch/transaction. Use this when performing bulk write operations like multiple inserts/updates; it saves the overhead of multiple database commits, greatly improving performance.

import { Couchbase } from 'nativescript-couchbase-plugin';
const database = new Couchbase('my-database');
 
database.inBatch(() => {
    const documentId = database.createDocument({
        "firstname": "O",
        "lastname": "Fortune",
        "address": {
            "country": "Trinidad and Tobago"
        }
        "twitter": "https://www.twitter.com/triniwiz"
    });
    
    const person = database.getDocument(documentId);
    
    
    database.updateDocument(documentId, {
        "firstname": "Osei",
        "lastname": "Fortune",
        "twitter": "https://www.twitter.com/triniwiz"
    });
    
    const isDeleted = database.deleteDocument(documentId);
});
