Configure git to diff Bun's lockb lockfile

<Note> 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. In 1.2.0+ it is the default format used for new projects. [**Learn more.**](/pm/lockfile#text-based-lockfile) </Note>

To teach git how to generate a human-readable diff of Bun's binary lockfile format (.lockb), add the following to your local or global .gitattributes file:

*.lockb binary diff=lockb

---

Then add the following to you local git config with:

git config diff.lockb.textconv bun
git config diff.lockb.binary true

---

To globally configure git to diff Bun's lockfile, add the following to your global git config with:

git config --global diff.lockb.textconv bun
git config --global diff.lockb.binary true

---

How this works

Why this works:

• textconv tells git to run bun on the file before diffing
• binary tells git to treat the file as binary (so it doesn't try to diff it line-by-line)

In Bun, you can execute Bun's lockfile (bun ./bun.lockb) to generate a human-readable version of the lockfile and git diff can then use that to generate a human-readable diff.
