Node-config

node-config steps

node-config

1) install the config module
npm install config

2) create a directory called ‘config’ in your application directory

3) create a file inside the ‘config’ directory called ‘default.json’
4) create a file inside the ‘config’ directory called ‘localhost.json’
5) create a file inside the ‘config’ directory called ‘development.json’
6) create a file inside the ‘config’ directory called ‘stage.json’
7) create a file inside the ‘config’ directory called ‘production.json’
8) create a file inside the ‘config’ directory called test.json’

In each json file, setup a corresponding mongodb connection string:

For example, in localhost:

{
  "dbString" : "mongodb://localhost:27017/homepage-app"
}

In your package.json file add the following scripts:

 "scripts": {
    "start": "node server.js",
    "localhost": "NODE_ENV=localhost node-dev server.js",
    "development": "NODE_ENV=development node-dev server.js",
    "test": "NODE_ENV=test node server.js",
    "stage": "NODE_ENV=stage node server.js",
    "production": "NODE_ENV=production node server.js"
  }

***********************************************************************************

In your db file, when connecting to the database, do something like this:

// fire up the database
var mongoose = require('mongoose');

// mongodb connection string
var dbString = require('config').dbString;
// log
console.log("Connecting to " + dbString + " ...");

// connect to mongo db
mongoose.connect(dbString);
// add to log (this should be callback)
console.log("Connected!")

// export the module to the application
module.exports = mongoose.connection;


***********************************************************************************


To start to the application run the corresponding npm script.  For example, to run locally, do:

npm run-script localhost

To run in development

npm run-script development
