Express.js

Maintainable Express.js code after scaling means making common code more feature-rich while reducing boilerplate. Find out how to enable promise-based route code and centralize both error handling and normal-results handling in Express.js apps.

Our Express.js REST API series ends with a bang! Learn how to add a Dockerized MongoDB instance, Mongoose, JWT authentication, user permissions, and automated testing with Mocha, Chai, and SuperTest.

The Express.js REST API journey continues! Move from models to full DAOs and DTOs, validate requests with middleware, separate services from controllers, and prepare for a real database.

Learn practical TypeScript patterns with interfaces and extended classes. Avoid messy console.log() statements with Winston and the Node.js debug module. Create an Express.js-powered REST API back end from scratch!

As patterns go, REST APIs are so useful and ubiquitous that every web developer, regardless of language or platform, should know how to build them.

In this article, Toptal JavaScript Developer Marcos Henrique da Silva shows how to create a simple and secure REST API for user management on Node.js.

Missing the luxury of a good, old-fashioned remote control when the laptop is beyond easy reach? Transform your old smartphone into a remote and learn some basic Node.js/Express/Pug along the way.

While Ruby has Rails and Python has Django, the dominant application development framework for Node has yet to be established. But, there is a powerful contender gaining steam: LoopBack, an open source API framework built by StrongLoop, the creators of Express.

Let’s take a closer look at LoopBack and it’s capabilities by turning everything into practice and building an example application.

After much thought, I decided to engineer a solution to the idea abandonment problem. I call it the ‘Init’ project (or Init.js).

The core of the idea is to have a single project to start them all, to let the developer or the technical founder make all of the essential decisions at once, and receive an appropriate starting template based on those decisions.
