reload-json

This module provides a way of loading JSON from disk in a way so that you know you always have the latest data without necessarily reloading the file every time the data is requested.

As an added bonus multiple requests for the same file in short sequence will be merged into a single fs.readFile

The first call will start a read of the file and then the callback is called as expected with the error or data object. If a second call happens while a read is already in progress that callback will be called when the read finishes with the same argument as the original callback.

A call to load at a later time will use a cached value unless the content has changed as determined by fs.watch. The module will also try to pre-emptively reload the files after a small delay when they change.

Usage

var Reloader = require('reload-json'),
  , reload = new Reloader()

reload.load('path/to/file.json', function (err, data) {
  // do stuff
})

Installation

npm install reload-json
