Web Front-end

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.

Time and date manipulation is notoriously difficult. Developers encountering time zone rules, leap seconds, differences in locale-specific formatting are wise to resort to popular time and date manipulation libraries. But without thinking about how exactly they work, it’s still easy to create all sorts of obscure bugs.

Git provides basic branching operations, but advanced patterns are left up to the user. The popular “Git flow” branching model helps, but can also complicate some common procedures.

Thankfully, a new variation retains the benefits, while streamlining everyday work.

The release of Vue 3 brought about substantial performance improvements, but they should not overshadow the introduction of new features and paradigms.

In this article, Toptal Full-stack Developer Luka Mikec introduces you to the new Composition API and explains what Vue 3 means for code expressiveness, organization, and reuse.

Pandoc is a software package capable of converting documents into various formats, and since it’s available as a Docker image, it’s easy to run.

In this article, Toptal Site Reliability Engineer (SRE) Phillip Edwards demonstrates how you can easily create a robust publication chain using Pandoc, Docker, and a pinch of Markdown.

Adopting declarative-style programming techniques allows teams to create web applications that are easier to extend and maintain.

In this article, Toptal Full-stack Developer Peter Suggate demonstrates how to leverage declarative programming and finite-state machines in JavaScript.

Mastering your IDE can go a long way toward improving productivity. However, many are reluctant to dive into customization and optimization.

In this article, Toptal JavaScript Developer Boris Yordanov explains how you can become a VSCode power user by leveraging official documentation and using a few practical tools.

JavaScript frameworks based on React can help you build a fast, reliable mobile app, but it’s not always easy to determine which framework is best for your project. Choosing the wrong framework can result in an app with slow and redundant code.

JavaScript expert Sean Wang builds the same natural language processing mobile application using Cordova, Ionic, and React Native, then discusses the advantages and limitations of each.

Employing a test-driven development (TDD) approach in React projects tends to be straightforward, especially with the aid of Jest and Enzyme. However, there are a few things to look out for.

In this article, a Toptal JavaScript expert demonstrates his React TDD process, from epics and user stories to development and production.

A relatively recent addition to React, hooks have already changed React development for the better through improved code readability and state management. But how do we test them?

In this article, Toptal React Developer Avi Aryan outlines why it is crucial to test hooks and introduces us to his React Hooks testing routine.

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.

Hooks have already changed the way we use React for the better. Add TypeScript to the mix, and developers can leverage static typing and type transformations to reduce the noise of many interface descriptions.

In this article, Toptal Software Developer Nicolas Zozol demonstrates hooks and TypeScript in React and explains how this powerful combo can save time and streamline your code.

“Every year the internet breaks,” goes the saying, and developers usually have to go and fix it. Is this true when it comes to the long-awaited Angular version 9?

Mobile and web applications typically need a back-end server, which requires maintenance, updates, backups, and more. So why not dispense with them?

In this article, Toptal Java Developer Phillip Edwards outlines how you can use Google Firebase to develop serverless applications without incurring a lot of costs.

Toptal’s JavaScript Speed Coding Challenge invited creative solutions from the beginning. As the week played out, competitors got closer and closer to the maximum theoretical score. Then something unexpected happened…

Inspired by stale-while-revalidate cache control logic, modern sites implement stale-while-refresh logic on the UI side. Thankfully, React Hooks make this logic painlessly reusable across components.
