Launch yourself into Ethereum smart contract development with the Truffle framework! In this tutorial, Toptal Freelance Ethereum Developer Radek Ostrowski shows you how to create a practical ĐApp in the Solidity language, complete with its own ERC20 token.

There are many programming platforms used to develop games, and there are a plethora of devices to play them on, but when it comes to playing games in a web browser, Flash-based development still leads the way.

What if we could port these games to HTML5 Canvas technology and play them on mobile browsers as well? In this article, Toptal engineer Avinash Kaza gave a solution to this.

The humble ERC20 token specification has become the de facto standard for Ethereum tokens. If you come across an Ethereum smart contract, chances are it’s ERC20-compliant.

In this guide, Toptal Freelance Ethereum Developer Gilad Haimov demonstrates how you can create and deploy your own ERC20 token in under an hour.

Elasticsearch provides a powerful, scalable tool for indexing and querying massive amounts of structured data, built on top of the Apache Lucene library.

Building on the foundation of Elasticsearch and the Elasticsearch-Ruby client, we’ve developed and released our own improvement (and simplification) of the Elasticsearch application search architecture that also provides tighter integration with Rails. We’ve packaged it as a Ruby gem named Chewy.

This post discusses how we accomplished this, including the technical obstacles that emerged during implementation.

Modern web development is a constant balance between client-side and server-side execution. This guide breaks down their responsibilities, trade-offs, and how contemporary architectures combine both to optimize performance, security, and user experience.

In this follow-up to his first highly popular AngularJS tutorial, Toptal engineer Raoni Boaventura guides you through the steps of setting up your project, including scaffolding, dependency management, and preparing it for testing.

Writing code that is easily testable takes some effort and planning. However, some patterns exist that can be used to write simple and functional code, making it easier to test them when the time comes.

In this article, Toptal engineer Joshua Mock shares some useful tips and patterns for writing testable code in JavaScript that are both simple to understand and simple to implement.

One of the most capable, extensible and popular front-end frameworks is AngularJS, and one of the most useful components of the AngularJS framework is something called a directive. In this article, the four functions that execute as a directive is created and applied to the DOM will be explored.

GraphQL is a domain-specific language for data query and manipulation by Facebook. It is meant to replace the de facto REST standard in API creation.

In this article, Toptal Freelance GraphQL Developer Ioram Gordadze creates a GraphQL API from scratch, summarizing problems new GraphQL developers face. He also teaches us to rethink the standard methods used in REST APIs in a more GraphQL-friendly manner.

Maintainable Express.js code after scaling means making common code more feature-rich while reducing boilerplate. Find out how to enable promise-based route code and centralize both error handling and normal-results handling in Express.js apps.

Considering you can include as much plain JavaScript as you like in your TypeScript project, what factors should you consider when choosing TypeScript for your application? Let’s explore.
