A package which allows for modular configuration loading from a specified directory
The package exports a class that can be instantiated to read configuration files from any specified directory.
Respondent requires 2 parameters. The first being the path to directory of your configuration files. The second being any environment variables you want to pass through to be loaded into your configuration files, the value is appended to the process.env global. That means whatever environment variables you pass through can be accessed via process.env
const Path = require('path');
const Respondent = require('respondent');
let config = new Respondent({
rootDir: Path.join(__dirname, 'config'),
env: {
someEnvValue: 'hello world' // In your configuration files, you can use `process.env.someEnvValue` to access this environment variable
}
});The get method in Respondent is used to retrieve specific values. The has method is used to determine if the value exists. Respondent uses dot notation in order to specify a path to a specific value. The syntax is as follows:
[fileName].[path]
app.name
app.database.host
It should be noted that if a file/value does not exist, no error will be thrown. Instead the return value is undefined and a debug message is outputted to the console.
Assume the following directory structure
├── main.js
└── config
└── app.js
app.js
module.exports = {
name: 'Respondent',
database: {
host: '127.0.0.1',
username: 'root'
},
options: {
currency: 'GBP'
}
};main.js
'use strict';
const Path = require('path');
const Respondent = require('respondent');
let config = new Respondent({
rootDir: Path.join(__dirname, 'config')
});
let name = config.get('app.name'); // 'Respondent'
let databaseHost = config.get('app.database.host'); // '127.0.0.1'
let databaseUsername = config.get('app.database.username'); // 'root'
let databasePassword = config.get('app.database.password'); // undefined
let currency = config.get('app.options.currency'); // 'GBP'
let country = config.get('app.options.country', 'United Kingdom'); // 'United Kingdom'
let hasCountry = config.has('app.options.country'); // false/**
* Retrieve the root path of the config directory.
*
* @returns {string}
*/
Respondent#getRootDirectory();
/**
* Retrieve a value from the specified path.
*
* @param {string} valuePath
* @param {string} defaultValue
* @returns value
*/
Respondent#get(valuePath, defaultValue);
/**
* Check if the specified path & value exists.
*
* @param {string} valuePath
* @returns {boolean}
*/
Respondent#has(valuePath);Respondent makes use of mocha in order to conduct it's unit tests, thus contributions should be submitted with unit tests relevant to your work.
