We actually don't need to use an .ini file for configuring our apps, as shown in a previous example. The purpose of the example was just to show you how to use a Node module, not the recommended practice.
As a side effect of how require() works, Node supports JSON-based configuration files by default. Create a file with a JSON object describing the configurations, save it with a .json extension, and then load it in the app file using require().
Note
It is important to ensure that the file extension is .json and the JSON object confirms to the JSON specification, or else it will throw an error.
Here is an example of a JSON-based config file:
{
"development": {
"db_host": "localhost",
"db_user": "root",
"db_pass": "root"
},
"production": {
"db_host": "192.168.1.9",
"db_user": "myappdb",
"db_pass": "!p4ssw0rd#"
}
}This is how you would load it:
var config = require('./config.json')[app.get('env')];
