JavaScript the Hard Parts: Build a Messaging Client

Learn async JavaScript to create real-time, interactive web apps.

JavaScript the Hard Parts: Build a Messaging Client

Ready to level up your asynchronous JavaScript skills?

In this hands-on workshop, we’ll build on the concepts from JavaScript the Hard Parts: Async & Promises as you create your very own browser-based messaging client. Guided by our expert Codesmith instructor, Marselena Sequoia, you’ll dive into real-world coding as you fetch data from a custom server, update the DOM in real-time, and build a fully interactive chat experience— right from your browser.

What you’ll learn:

  • Async/await patterns for seamless, real-time communication
  • How to fetch and post data using a custom server API
  • Techniques for building dynamic, data-driven user interfaces
  • A practical introduction to client-server communication on the modern web

By the end of this workshop, you’ll have built a functioning mini messaging app—and gained the confidence to tackle more complex, server-connected applications in your coding journey.

Is this workshop right for you?

This workshop is open to all experience levels! We recommend completing the Precourse unit on our free learning platform CSX, to set yourself up for success, but no prior experience is required. Whether you’re just curious or ready to begin a new career path, this workshop is designed to meet you where you are.
