lockfile
Read, write, and convert npm (v1, v2) and yarn (classic and berry) lockfiles in any directions with reasonable losses.
Motivation
Every package manager brings its own philosophy of how to describe, store and control projects dependencies.
This is awesome for developers, but literally becomes a pain in *** *** headache for isec, devops and release engineers.
This lib is a naive attempt to build a pm-independent, generic, extensible and reliable deps representation.
The package manifest contains its own deps requirements, the lockfile defines the deps resolution snapshot*, so both of them are required to build a dependency graph. We can convert this data into a normalized representation for further analysis and processing (for example, to fix vulnerabilities). And then, if necessary, convert back to the original format.

Install
yarn add @antongolub/lockfileUsage
import { parse, format } from '@antongolub/lockfile'
const parsed = parse({
lockfile: './yarn.lock',
workspaces: {'': './package.json', 'foo': './packages/foo/package.json'},
})
// output
