A Node.js Perspective on MongoDB 4.0: Transactions

  • MongoDB has supported ACID for single document operations for many years, and denormalized data meant many apps didn’t need transactions.
  • In this article, I’ll demonstrate using transactions with the MongoDB Node.js driver and mongoose.
  • Transactions with Mongoose are similar to with the MongoDB driver.
  • With both Mongoose and the MongoDB Node.js driver, MongoDB will report a WriteConflict error if two transactions attempt to write conflicting data, like if two calls attempt to transfer money from the same account at the same time.
  • So download run-rs, MongoDB driver 3.1.0, and Mongoose 5.2.0 and get started with transactions today!
