A more friendly way to use config file when you have many env,let the env config to merge default config

npm i more-express-config --save

demo

config/app.json

{
  "hello":"app in default"
}

config/[env]/app.json

{
  "hello":"app in test"
}

app.js

var configure = require('more-express-config');

console.log(configure.get('app'));

NODE_ENV=test node app.js

output

{
  "hello":"app in test"
}

support .js, .json, .node, .yaml, .yml
