Bun v0.1.7

To upgrade:

bun upgrade

To install:

curl https://bun.sh/install | bash

curl https://bun.sh/install | bash

What's new

bun init quickly start a new, empty project that uses Bun (similar to npm init). bun init is a new subcommand in bun.

bun install now supports private npm registries & scoped (authenticated) packages

Thank you @soneymathew for your help with this.

bun install now supports lifecycle hooks for project-level package.json (not dependencies)

It runs postinstall scripts for your app's package.json, but ignores dependencies lifecycle hooks. This lets you use husky, lint-staged, and other postinstall-dependent packages tools

More new stuff:

• express is partially supported, thanks to @zhuzilin and @evanwashere. There is a lot more work to be done - it's not fast yet and it logs a spurious error on request, but it is better than not working
• bun create now lets you specify a start command so that you can say how to run the program in the output
• process.revision has the git sha that bun was built with

Breaking changes

• bun install will invalidate the lockfiles on upgrade if it exists. Unfortunately, this is necessary to support private/scoped package installs
