Pessimistic Locking in Node.js with TypeORM

In this article, we will explore pessimistic locking, its main aspects, and how to implement it in Node.js using TypeORM. Pessimistic locking is a strategy to prevent concurrent access to a resource by obtaining exclusive access to the resource before making any changes. This approach ensures that other transactions cannot modify the locked resource until the lock is released.

We will use a practical example to demonstrate how to implement pessimistic locking in a Node.js application using the TypeORM library. Our example will focus on a payment processing scenario, where multiple processes might attempt to update the status of a payment concurrently.

"Vendoring" is a vile anti-pattern

What is "vendoring"?

From a comment on StackOverflow:

Vendoring is the moving of all 3rd party items such as plugins, gems and even rails into the /vendor directory. This is one method for ensuring that all files are deployed to the production server the same as the dev environment.

The activity described above, on its own, is fine. It merely describes the deployment location for various resources in an application.
