Config overwrite

Allow your users to overwrite default config.

Install

$ npm install --save config-overwrite

Usage

The function requires two parameters, both can be an object or a path as a string. The first parameter is the global config which you provide, the second will be the local overwrite. The local file only needs to contain the keys to be overwritten.

If a version key is provided in both config files, the function will check if they are the same. If the versions do not match, the process wil be exited.

Example:

var configoverwrite = require('config-overwrite');
var config = require('./config.json');

var configuration =  configoverwrite(config, './config.local.json', function(err, response) {
  if (err)
    console.log ('error', err.message, err.stack)
  else
    return response
});

config.json:

{
  "version": "1.0.0",
  "fist": "Hello",
  "second": "Hey",
  "third": {
    "sub": "Sub levels work too",
    "sub-two": "Let's try"
  }
}

config.local.json:

{
  "version": "1.0.0",
  "first": "Bye",
  "third": {
      "sub-two": "See, it works"
    }
}

result:

{
  "version": "1.0.0",
  "fist": "Bye",
  "second": "Hey",
  "third": {
      "sub": "Sub levels work too",
      "sub-two": "See, it works"
    }
}
