park

A simple utility and CLI for getting and setting values on the closest package.json.

Mostly useful for quickly changing values or copying values to the keyboard. If you need anything more, npm and vim package.json have you covered.

Usage

CLI

First install it via npm.

$ npm install -g park

It's now available on your command line.

Get a value from package.json

$ park description
# => CLI for getting and setting package.json values. Useful for quickly changing values and copying values to the keyboard. 

Especially useful if you pipe it to your clipboard. For example, I use this all the time when starting Github repos:

$ park description | clip # clip is Windows. Mac and Linux users use pbcopy and xclip respectively. 

park accepts object strings as keys for getting nested values.

For example, scripts.test will access the test key of scripts.

$ park scripts.test
# => cd test/ && mocha . && cd .. 

Set a value in package.json

$ park main park.js
# => package.json contents 

Or with an object string:

$ park scripts.test mocha

Stream out the package.json object

It's equivalent to using cat package.json, but also works from any subdirectory.

$ park
# => package.json contents 

API

The programmatic API is more or less identical.

First install it.

$ npm install --save park

Then require it in your code. park is a function which accepts a directory path.

var park = require("park"),
    pkg = park(__dirname);

The following methods will be available on the object park(dir) returns.

pkg.read()

Returns a readable Stream of the package.json file.

pkg.read().pipe(process.stdout);

pkg.get(key)

Get a key from package.json.

pkg.get("version"); // => "1.0.0"

You can use object strings in the API too.

var chaiVersion = pkg.get("devDependencies.chai");

pkg.set(key, val)

Set a key in package.json as val and save the file. Returns a writeable Stream.

pkg.set("version", "1.0.1").on("finish", function(){
    console.log("Saved!");
});

Or with an object string.

var stream = pkg.set("bin.park", "bin/cli.js");

pkg.save()

Manually save package.json as pkg.obj. Useful if you want to edit the object manually.

pkg.path

Full path of the package.json file.

pkg.obj

package.json contents as an object.
