Overview
The npm lockfile that pins the exact resolved versions and integrity hashes of every direct and transitive dependency in the TestCafe project for reproducible builds.
Description
This auto-generated JSON file records every dependency's specific version, registry URL, and integrity hash (SHA-512). When npm install or npm ci is run, npm reads this file to install the exact same dependency tree rather than resolving version ranges from package.json. At 18,670 lines, its size reflects the breadth of TestCafe's dependency tree.
Usage
This file is consumed automatically by npm during installation. Use npm ci in CI environments for deterministic installs based on this lockfile. Do not edit manually.
