Hi everyone (again)!

In my previous blog entry, I wrote the first part of our guide to create APIs using Node.js.

In this part, I'll give a quick introduction to express.js in order to understand how the Processes engine is organised (and the rationale behind). This is a pure technical javascript post, so be warned! ⚠️

Disclaimer: the source code examples are, in most of the cases, a simplification of the real code for easier legibility and to avoid compromising our client's code.

Are you ready to learn how express.js works? Let's dive into it!
