Experimenting with the new bun runtime with the astro framework.

Note: I ultimately didn’t deploy Astro with bun because of bun’s current limitations. You can watch the stream to see me work through the issues, or read the highlights below.

Highlights

• Bun is fast! Install times are significantly faster
• Sharp isn’t supported by bun yet, so I had back to Squoosh to get images working
• Netlify can’t build, there seems to be something wrong with how dependencies are installed
• Vercel can build, but the View Transitions API doesn’t work on the deployed site

• Example of React app that you can deploy to netlify using bun (bun.js, oven.sh)
