How to Interact With a Database Using Various async Patterns in Node.js
It seems simple enough: Get a connection to the database, use it to do some work, then close it when you're done. But due to the asynchronous nature of Node.js, coding this sequence isn't as straightforward as it seems. There are lots of options for writing asynchronous code with Node.js, and each one requires the sequence to be coded differently. In this series, I'll provide some examples that demonstrate how to get, use, and close a connection using various async patterns.
In this parent post, I'll provide a little context on how async programming varies from traditional programming. The details of how a particular async pattern is used will be covered in its own post (see the links at the bottom).
