Couchbase Transactions — Node.js

ACID multi-document transactions. All operations commit atomically or roll back entirely.

Version requirement: Distributed transactions require Couchbase Server 7.0+. The 6.6 developer preview is not recommended for production.

Bank Transfer Example

await cluster.transactions().run(async (ctx) => {
    const sender   = await ctx.get(collection, 'acct_alice');
    const receiver = await ctx.get(collection, 'acct_bob');

    const senderDoc   = sender.content;
    const receiverDoc = receiver.content;

    if (senderDoc.balance < amount) throw new Error('Insufficient funds');
