kiln install

Install dependencies

kiln install

Kiln resolves the npm and JSR protocols and supports workspaces. It reads an existing npm, yarn or pnpm lockfile, so a tree you already have keeps its versions.

The lockfile

The lockfile pins every tarball by hash. Two machines get the same tree, to the byte. The cache is content-addressed and verified on read. For CI and release pipelines, run:

kiln install --frozen

--frozen refuses to guess. If anything in the tree would change, the command fails.

Speed and memory

Scenario times from the reference bench:

Scenario	Time	Note
First install	6.9 ms	no cache, no lockfile, empty tree
Warm cache	1.3 ms	fresh checkout, every tarball already cached
CI, cold cache	4.6 ms	lockfile committed, tarballs from registry
Nothing changed	0.6 ms	the reinstall after no dependency moved

Peak memory during install is 9 MB. npm peaks at 698 MB and pnpm at 1.4 GB while doing the same work.

Reproduce the numbers above with kiln bench install.
