Yarn.Lock

Contents

Description

The Yarn package manager improves on npm, because it writes yarn.lock files that contain a complete version resolution of all dependencies. This way a deterministic deployment can be guaranteed.

Synopsis

Documentation

type Lockfile = MKMap PackageKey Package Source #

Yarn lockfile.

It is a multi-keyed map (each value can be referenced by multiple keys). This is achieved by using an intermediate key ik.

Attention: Might be changed to a newtype in a future release.

parseFile Source #

Arguments

:: FilePath

file to read

-> IO (Either LockfileError Lockfile) 

Convenience function, combining all parsing steps.

The resulting Lockfile structure might not yet be optimal, see fromPackages.

parse Source #

Arguments

:: FilePath
