Node.js Environment Loading environment properties from a "property file"
Example
- Install properties reader:
npm install properties-reader --save
- Create a directory env to store your properties files:
mkdir env
- Create environments.js:
process.argv.forEach(function (val, index, array) {
var arg = val.split("=");
if (arg.length > 0) {
if (arg[0] === 'env') {
var env = require('./env/' + arg[1] + '.properties');
module.exports = env;
}
}
});
- Sample development.properties properties file:
# Dev properties
[main]
# Application port to run the node server
app.port=8080
[database]
# Database connection to mysql
mysql.host=localhost
mysql.port=2500
...
- Sample usage of the loaded properties:
var enviorment = require('./environments');
var PropertiesReader = require('properties-reader');
var properties = new PropertiesReader(enviorment);
var someVal = properties.get('main.app.port');
- Starting the express server
npm start env=development
or
npm start env=production
