Minimize Heap Allocations in Node.js

Memory management has always been a source of huge concern in Computer Science. Each piece of software is assigned a small portion of a computer’s finite memory; this memory has to be well-managed (carefully allocated and deallocated). With its efficient automatic garbage collection mechanism, Node.js tries to handle the tedious task of memory management and free up developers to work on other tasks.


Nest.js vs. Express.js: A Contest of Node Frameworks

What a time to be alive! The information age we are currently in has given us more data and choices about, well, everything. But let’s be honest, do any of us actually feel like we’re more informed than we were? Because all this information comes with more choices. Expanded choice is actually an “explosion of choice” – in other words, if the world were a restaurant, the menu is so long you spend more time choosing your order than actually eating it.


Secure Your Node.js App with JSON Web Tokens

A JSON Web Token (JWT) is an open standard (RFC 7519) that securely sends and receives data between parties (in the form of a JSON object). In this article, we’ll implement JWT authentication to secure a Node.js application. We’ll also find out what JWT is all about and build a demo app. Let's get going!


Is Deno better than Node.js?

The Deno runtime for JavaScript and TypeScript is created on Rust and the V8 JavaScript engine, equivalent to Node.js. Developed by Ryan Dahl, Node.js' original creator, it is designed to correct errors he made when he first envisioned and unleashed Node.js in 2009. To recapitulate, he was dissatisfied with the lack of security, the lack of module resolution through node_modules, and the differing behaviour of the browser, among other things, which provoked him to implement Deno.


How To Avoid SSR Load Issues in Node.js

In my experience consulting the past few years, one thing has become clear: everyone struggles with scaling their SSR apps, no matter the chosen framework. SSR is expensive — running a lot of code intended for the browser, on the server, to pre-generate markup. Lately, web frameworks have been making strides in improving things, Solid.js being a great example of fast, performant SSR.


4 Ways to Minimize Your Dependencies in Node.js

We all know the joke about how node_modules is the heaviest object in the universe. For example, a project that uses only fastify, knex, typescript, and uuid generates an 83MB node_modules folder! That's huge! And those four packages are far from a complete set for a relatively small back-end. A more realistic size for node_modules is north of 100MB, in some cases reaching 1GB.


Build a CRUD App with Node.js and MongoDB

Choosing the right tool for a web application can be tricky. But if you do, it will make things a lot easier for you. Depending on your application, combining Node.js and MongoDB works well most of the time — especially if you use a front-end framework like React (MERN), Angular (MEAN), or Vue (MEVN). In this tutorial, you will learn how to create a CRUD application using Node.js and MongoDB and write some basic tests for your Node.js API.


Distributed Tracing Support in N|Solid [10/10] The best APM for Node, layer by layer.

Complex modern systems are the new reality for infrastructure teams, and this is due to the evolution of Cloud Computing and working with Distributed systems, containerization, and microservices by default. The teams now have different infrastructures and virtual services with which they must take care of scalable, reliable, and performative applications.
