Bun v0.8.0 ( bun.sh )

Bun is an incredibly fast JavaScript runtime, bundler, transpiler, and package manager — all in one.

Bun v0.8.0 adds debugger support, implements fetch streaming, and unblocks SvelteKit. ReadStream and WriteStream from node:tty are implemented, and .setRawMode() now works on process.stdin, unblocking several interactive CLI tools. Plus Node.js compatibility updates, bug fixes, stability improvements.
