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.

Deploying instances of a web application to one or more servers manually can often be a monotonous process, and take up a significant amount of your time. With little effort, it is possible to automate the process of deploying your web application with almost zero human intervention. This article outlines a simple approach to automating web application deployments using GitHub webhooks, buildpacks, and Procfiles.

Caching is a powerful technique for increasing performance, but the whole idea behind caching works only as long as the result we cached remains valid. And here we get to the hard part of the problem: How do we determine when a cached item has become invalid and needs to be recreated?

In this article, Toptal Freelance Software Engineer Daniel Ivanov provides an ASP.NET-based solution to replace invalid cached items and assure high throughput and performance of web applications designed to handle a high load.

Thanks to rapid advances in technology, large amounts of data generated on social networks can be analyzed with relative ease, especially for those who use the R programming language and Gephi.

Static websites are simple and fast, but it’s also possible to automate updates to them to keep them fresh and relevant. Find out how to generate daily-updated HTML pages that track the latest releases of popular GitHub repositories.

The Bitcoin Lightning Network is an independent solution that’s heralded as the solution to bitcoin’s scaling problem by keeping fees minuscule and making transactions instant, away from the blockchain.

In this article, Toptal Freelance Blockchain Developer Amin Shah Gilani explores what the Bitcoin Lightning Network really is, how it can make the guarantees it provides, and its current state.

Analysts have come to recognize social network data as a virtual treasure trove of information for sensing public opinion trends and groundswells of support. In this article, Toptal Engineer Elder Santos describes the techniques he employed for a proof-of-concept that effectively analyzed Twitter Trend Topics to predict, as a sample test case, regional voting patterns in the 2014 Brazilian presidential election.

Inheriting someone else’s code can be a nightmare, especially when the code is poorly designed and lacks documentation. In this post, Toptal Engineer Juan Pablo Scida provides a case study of how he reengineered a chat server written in Node.js, transforming its original spaghetti code into a cleanly architected and designed piece of software.

Would you rather develop a statically or dynamically typed programming language? How would you devise your expression parser?

In the second part of our Stork series, Toptal Full-stack Developer Jakisa Tomic outlines his preferred approach and demonstrates how you can create a functional expression parser.

WebAssembly gives near-native performance to web apps and allows languages other than JavaScript—plus their libraries—to be used on the web. This tutorial leverages Rust and the Web Audio API to make a basic guitar tuner app that runs at 60 FPS, even on mobile.

Linux namespaces make it possible to run a whole range of applications on a single real machine and ensure no two of them can interfere with each other, without having to resort to using virtual machines. In a single-user computer, a single system environment may be fine. But on a server, where you may want to run multiple services, it is essential to security and stability that the services are as isolated from each other as possible.
