Bun v1.1.39 introduced bun.lock, a JSONC formatted lockfile. bun.lock is human-readable and git-diffable without configuration, at no cost to performance. Learn more.
Use the --yarn flag to generate a Yarn-compatible yarn.lock file (in addition to bun.lock).
terminal
bun install --yarn
To set this as the default behavior, add the following to your bunfig.toml file.
bunfig.toml
[install.lockfile]
print = "yarn"
To print a Yarn lockfile to your console without writing it to disk, “run” your bun.lockb with bun.
terminal
bun bun.lockb

# THIS IS AN AUTOGENERATED FILE. DO NOT EDIT THIS FILE DIRECTLY.
# yarn lockfile v1
# bun ./bun.lockb --hash: 9BFBF11D86084AAB-9418b03ff880c569-390CE6459EACEC9A...
