Bun is a modern JavaScript runtime built for speed, simplicity, and developer productivity. In this course, you will learn how to use Bun to build real, production-ready fullstack applications with TypeScript and JavaScript, all using a single, fast toolchain.
This course takes a practical, API-first approach. Instead of abstract theory, you will work directly with Bun’s core features, including its built-in web server, test runner, bundler, package manager, and database integrations. You will learn how to create backend APIs, serve frontend assets, manage environment configuration, and structure fullstack projects efficiently.
Starting from the fundamentals, you will explore how Bun differs from Node.js and other runtimes, when and why to use it, and how to migrate or start new projects confidently. As the course progresses, you will build increasingly complete applications, learning best practices for routing, middleware, data access, performance, and testing along the way.
By the end of this course, you will be able to design, build, test, and deploy fullstack applications using Bun, with a strong understanding of its APIs and ecosystem. Whether you are a JavaScript developer looking to modernize your workflow or a TypeScript user who wants faster builds and simpler tooling, this course will give you the skills to use Bun effectively in real projects.
