Some platforms have an overwhelming number of options for web frameworks. Node.js, the event-driven server-side JavaScript environment, is one such platform. Whether it’s the minimalist Express or the full-blown MVC web framework Sails.js, Node.js seems to have it all.

In this article, Toptal Freelance Software Engineer Chuoxian Yang explores four of the most popular Node.js web frameworks and discusses how each framework stands out from the rest of the crowd in Node.js.

Today, a massive amount of data is available in the form of networks or graphs. For example, the World Wide Web, with its web pages and hyperlinks, social networks, semantic networks, biological networks, citation networks for scientific literature, and so on.

A tree is a special type of graph, and is naturally suited to represent many types of data. The analysis of trees is an important field in computer and data science. In this article, we will look at the analysis of the link structure in trees. In particular, we will focus on tree kernels, a method for comparing tree graphs to each other, allowing us to get quantifiable measurements of their similarities or differences. This an important process for many modern applications such as classification and data analysis.

Kubernetes (“K8s”) won the battle of container orchestration tools. Now AWS, Azure, and Google Cloud each offer a managed Kubernetes version. How do they compare?

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.

Understanding the Input/Output (I/O) model of your application can mean the difference between an application that deals with the load it is subjected to, and one that crumples in the face of real-world uses cases. Perhaps while your application is small and does not serve high loads, it may matter far less. But as your application’s traffic load increases, working with the wrong I/O model can get you into a world of hurt.

Robot Operating System, a framework for building robot applications, allows developers to assemble a complex system by connecting existing solutions for small problems.

In this article, Toptal engineer Adnan Ademovic gives us a step-by-step tutorial to building software for an onboard computer that allows us to remotely control and monitor a robot and running it in a simulated world using Robot OS.

Developing a new programming language from scratch tends to create unique challenges, followed by unconventional solutions that may go against some programming dogmas.

In Part 3 of our Stork series, Toptal Full-stack Developer Jakisa Tomic elaborates on how C++ macros can help and why expression implementation might not be as straightforward as expected.

Centrality and text analysis allow users to get more out of their social network data. Here’s how you can leverage them using R and Gephi.

Gone are the days where front-end developers for web applications could use ad-hoc JavaScript with jQuery and such all in a single JavaScript file. Modern web applications require more effort from the developer to adopt an overall architecture and development process. Building such front-end applications relies on lots of external dependencies and modular source code, and these elements necessitate automation to save developers time and reduce the chances of mistakes.

In this article, Toptal Freelance Software Engineer Eric Grosse shows us how various combinations of the popular tools Webpack, Browserify, Gulp and Npm can benefit us by enhancing our development environment and allowing us to focus on writing the app itself.

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.

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.
