Bun is a modern, high-performance JavaScript runtime that combines a package manager, a testing framework, a project builder, and a set of built-in APIs. In this practical guide, you will explore through examples how Bun simplifies development and when it becomes a better choice compared to Node.js.
Course Description
The course is built around real examples and demonstrations. Instead of mechanically writing code, you will study ready-made snippets and analyses of architectural solutions to better understand the principles of how Bun works and its role in the modern ecosystem. You will learn to run JavaScript and TypeScript applications, manage dependencies, create servers, route, use Bun's built-in APIs, work with SQLite, SQL, and S3-compatible storage, WebSocket connections, testing, and building standalone applications.
You will learn to use Bun.serve() to create server applications, apply built-in tools for file and image handling, connect databases, optimize projects, and create executable files. A separate emphasis is placed on the practical simplification of development thanks to the unified Bun platform.
Practical Project
The final part of the course is dedicated to a detailed analysis of a full-fledged social network application where Bun is used as the server foundation. Through this project, you will see how routing, working with SQLite, uploading and processing images, interacting with S3-compatible storages, testing, and other Bun capabilities unite in creating a real product.
What You Will Learn
- Understand the role of Bun in the modern JavaScript and TypeScript ecosystem.
- Launch and configure projects using Bun.
- Manage dependencies and application configuration.
- Use Bun's compatibility with Node.js for a smooth transition to the new platform.
- Create HTTP servers, set up routing, and handle requests.
- Work with built-in APIs for files, images, Markdown, and environment variables.
- Connect to SQLite, execute SQL queries, and use S3-compatible storages.
- Develop WebSocket-supported applications.
- Write tests in the built-in Bun testing framework.
- Build applications and form standalone executable files.
- Analyze the architecture of a full-fledged web application in Bun.
- Determine in which projects Bun is most effective, including scenarios using AI code generation.
Who This Course Is For
The course is suitable for web developers who want to learn Bun and understand its practical advantages; specialists working with Node.js who are considering Bun as an alternative or complement; fullstack developers striving to use a single tool for server logic, dependency management, file handling, databases, testing, and application building.
