Get Root Path - NodeJS

* Stop counting dots - get the project root path with a single import
* (...or a single require if you're oldskool)
* Memoizes the result for rapid lookups after initial run

What is the root path?

* The nearest directory up the file system tree with a package.json file.

Installation

npm install --save get-root-path

Basic usage

import { rootPath } from 'get-root-path';

path.join(rootPath, 'build/app/client');

* If you set the APP_ROOT_PATH environment variable, it will return the
value of APP_ROOT_PATH as the root path instead.

Real-world usage

import { rootPath } from 'get-root-path';

const app = express()
.use('/', express.static(path.join(rootPath, 'build/app/client')));

What it does

* No magic: it just finds the nearest parent (ancestor?) directory containing a package.json file
* 99% of the time this will be the project root of the file doing the lookup.
