bun-development

To set up a new Bun project with TypeScript, initialize the workspace using Bun and apply Bun-friendly TypeScript settings like bundler module resolution. You can then configure dev, test, and build scripts to leverage fast iteration and execute TypeScript directly without extra compilation.

Migrating a Node.js project to the Bun runtime involves identifying Node-to-Bun changes for imports and globals, then substituting recommended Bun equivalents for performance. You must also update dependency management commands to use bun add and bunx for one-off executions.

You run tests using the bun test command with common options for watch or hot mode, and bundle production builds using Bun.build. This workflow accelerates JavaScript and TypeScript development by executing code directly and bundling outputs efficiently.

Bun handles dependency management through commands like bun add, remove, and update. It manages lockfiles using the binary bun.lockb format or text lockfiles, and utilizes bunx for running one-off commands without globally installing packages.

When moving from Node.js to Bun, runtime differences primarily affect imports and global variables. You need to identify Node-to-Bun changes and apply correct migration notes to ensure Node compatibility while troubleshooting runtime differences.

Bun supports executing TypeScript files directly, accelerating JavaScript and TypeScript development by eliminating the need for a separate compilation step. You can run code immediately, leverage watch mode for fast iteration, and bundle with Bun.build.
