putTransaction lets you submit multiple database operations as a single atomic batch. Either all operations succeed, or the entire batch fails. You will never see partial updates. This API will return a promise that gets resolved once the transaction has been fully applied and durably persisted to the database.
userbase.putTransaction({
databaseName: 'example-database-name',
operations: [
{ command: 'Insert', item: { example: 'Sample Item A' } },
{ command: 'Update', item: { example: 'Sample Item B' }, itemId: '0002' },
{ command: 'Delete', itemId: '0003' }
]
}).then(() => {
// transaction applied
}).catch((e) => console.error(e))
