I have always been of the understanding there are no common sense rules about how to create a minimal Node.js application with Babel. In my search for these answers, it seemed that every tutorial I came across showed something different. As a result, I wanted to streamline this project setup for my readers and myself, so I developed a common…

You may be already using npm (node package manager) for installing libraries (node packages) to your JavaScript projects. For instance, in Node.js you may be used to Express.js for creating REST APIs . In frontend development, you may be used to React.js to build component-based web applications. This makes you a consumer of the npm ecosystem…

This tutorial demonstrates how to setup testing with Mocha, Chai, and Sinon in Node.js. Whereas the previous tutorial has already shown you how to setup your Node.js application, this tutorial sets up a testing environment for your Node.js project. Let's dive into it by setting up Mocha with Chai and Sinon as testing framework. Node.js with Mocha…

Node + Express + PostgreSQL is a powerful tech stack for backend applications to offer CRUD operations. It gives you everything to expose an API (Express routes), to add business logic (Express middleware and logic within Express routes), and to use real data with a database (PostgreSQL). It's perfect for establishing a PERN (PostgreSQL, Express…

Node + Express + MongoDB is a powerful tech stack for backend applications to offer CRUD operations. It gives you everything to expose an API (Express routes), to add business logic (Express middleware and logic within Express routes), and to use real data with a database (MongoDB). It's perfect for establishing a MERN (MongoDB, Express, React…

Eventually every Node.js project running with Express.js as web application will need a database. Since most server applications are stateless, in order to scale them horizontally with multiple server instances, there is no way to persist data without another third-party (e.g. database). That's why it is fine to develop an initial application with…

This is a tutorial for setting up MongoDB on MacOS. You might be wondering why there's a need for another setup guide for MongoDB in the first place, since there are a few across the web. I found many tutorials and guides on how to set it up, but found most of them to be unclear and outdated, based on old MongoDB versions. The checklist is not…
