Node.js

To protect client data, your system must identify and block uninvited visitors. Create a REST API using Node.js, TypeScript, and Express, enhanced with JWT support.

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.

Node.js developers often find themselves working with chaotic code that’s anything but clean. This can obviously cause productivity issues and outright errors.

In this article, Toptal Full-stack Developer Jay Huang will introduce you to error-handling in Node.js and demonstrate how you can build a robust error-handling system yourself.

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.

The main artifact of all your work is most likely plain text files. So why don’t you use Notepad to create them? Find out how the Language Server Protocol can transform text editors into code editors, without coupling.
