- When you pass `new Response` an S3 file, it turns into a redirect to a presigned expiring URL so that you don't waste your server's resources downloading to S3 and sending to the user
- The API is designed to work very similarly to Response, Blob, and Bun.file(path), so you can read from S3 just like from the local filesystem or fetch().

- In the next version of Bun `bun.lock` is the new lockfile in `bun install`
- [Not loaded yet]
- yeah
- Merge conflicts are inevitable, and that's why we put each package and it's dependencies on a single line. Fewer lines means easier merge conflicts.
- Bun will continue to support the binary `bun.lockb` for awhile. `bun.lock` will be the default for `bun install` after Bun v1.2. To try the new text-based lockfile before then, use the `--save-text-lockfile` flag and upgrade to --canary.
- Unlike bun.lockb, this lockfile is human readable, which is important when working in teams The lockfile format is jsonc, like tsconfig.json. Trailing commas and comments are allowed.
