Memoize the results of the path.relative function
npm install cached-path-relative
Memoize the results of the path.relative function. path.relative can be an expensive operation if it happens a lot, and its results shouldn't change for the same arguments.
$ npm install cached-path-relative
Use it just like your normal path.relative, but it's memoized:
``javascript
var relative = require('cached-path-relative')
relative('test/index.js', '.') === '../..'
`
If you want to shim path.relative globally so that you can optimize things that don't know about this module (browserify rebuild times are a good use-case here), you can just import the shim:
require('cached-path-relative/shim')
This will globally shim path.relative` so that its results are cached.
