packhorse

API for updating multiple packages like package.json and bower.json.

Installing

$ npm install packhorse

API

packhorse

packhorse.load(packages) -> promise(pack)

Accepts an Array of package configuration and loads them into the Pack. A package can be a:

• path to a package (string)
• an object with:
  • path (string)
  • optional (boolean)

packhorse.load([
 './package.json', // required
 './bower.json', // required
 {path: './component.json', optional: true} // optional, will be ignored if not present
])
.then(function (pack) {
  // use Pack API
});

Paths are resolved relative to the current working directory for the process. The first package will be considered the "leader" for pack.get calls. Packages where optional is true will be excluded if they are not found.

In addition to load, packhorse exposes the Pack and Package constructors.

Pack

A Pack controls batch operations across many Package instances.

get(key) -> any

Gets data from the first package stored at key.

set(key [, value]) -> pack

Sets a value on all packages in the pack. set can be called with a key value pair or an object.

read() -> promise(pack)

Reads in data for all packages in the pack. Returns a promise that resolves when all packages have been read.

write() -> promise(pack)

Updates data for all packages in the pack. Returns a promise that resolves when all packages have been written.

paths() -> Array

Returns an array containing the paths of each package in the pack.
