Fork notes:

• removed all that is not related to lock file parsing
• removed types annotations
• simplified build process
• replaced/inlined external deps, except js-yaml

So, no package contains only parsing yarn.lock file functionality and can be used in browser env.

yarn-lockfile

Parse and/or write yarn.lock files

Usage Examples

1const fs = require("fs");
2const lockfile = require("@yarnpkg/lockfile");
3// or (es6)
4import fs from "fs";
5import * as lockfile from "@yarnpkg/lockfile";
6
7let file = fs.readFileSync("yarn.lock", "utf8");
8let json = lockfile.parse(file);
9
10console.log(json);
11
12let fileAgain = lockfile.stringify(json);
13
14console.log(fileAgain);
