converge-peer-dependencies

Converge peer dependencies in package.json

Description

This tool can be applied on a NodeJS (or Babelized) project, after dependencies have been installed, to gather all peer dependencies of the dependencies in package.json, converge them, if possible, among themselves and the other dependencies, and add them back to package.json.

On success, it returns an object with existing dependencies that changed and new dependencies that were added.

{
  depChanged,
  depAdded
}

Usage

const { converge } = require('converge-peer-dependencies');

converge('./dir/to/app').then(ret => {
  console.log(JSON.stringify(ret, null, 2));
})
.catch(e => {
  console.log(JSON.stringify(e));
});

An optional options object can be provided as second argument, with the following structure.

option	default	description	example
matcher	null	boolean predicate on the package name	n => !n.startsWith('react')
