Project Bun

Project Bun is an experiment exploring a minimal Bun app that uses core Bun APIs and as few dependencies as possible.

It includes:

• A vanilla Bun HTTP server that handles requests, including:
  • form posts
  • streaming React from the server using the renderToReadableStream API
  • a websocket server
  • serving a client-side bundle using Bun.build that hydrates the server-rendered React
• A basic example using a counter to increment and decrement a counter stored in global state
• A basic example using server-rendered react that lets you create tasks via traditional form posts and store them in a SQLite database using Bun's native SQLite driver
• A basic chat app that hydrates React on the client, connects to the Bun websocket server and allows a user to send messages
• Watchs and reloads the dev server using Bun watch

Bun has a lot of interesting APIs that are surprisingly capable and fun to build with. The only dependencies used are React and React DOM.

Obligatory Disclaimer: this was purely for fun, is not production ready, and should be used for reference only.

Development

To install dependencies:

bun install

To run:

bun migrate src/db/migrations/2024-10-04-tasks.sql # migrate the tiny sqlite database
bun dev

This project was created using bun init in bun v1.1.29. Bun is a fast all-in-one JavaScript runtime.
