NPM Shrinkwrap to Yarn lockfile

Migrate your npm-shrinkwrap.json to a yarn lockfile without a headache!

The migration consists of three steps:

• extract the dependency versions from the npm-shrinkwrap.json;
• save and lock down these versions in the package.json (by removing the version leniency, i.e. ~ and ^);
• generate a new yarn.lock file from the updated package.json.

Installation

yarn global add shrinkwrap-to-lockfile

How to use

shrinkwrap-to-lockfile [npm-shrinkwrap-file] [package-file]

That's it!
