Pigura

Simple configuration file loader.

What is It?

1. Let's say you have a file named config.json containing your app settings.

2. You have a file named config.prod.json containing your app settings for PRODUCTION.

3. Running your app on development mode, will only load config.json.

4. Running your app in production, will load both config.json, MERGED with config.prod.json

5. You dont need to copy all the settings from config.json to config.prod.json. Just the settings to override. Removing the need to maintain both files in sync.

Install

Choose 1 of 3 options:

Install from NPM:

npm install pigura

Install latest from GitHub:

npm install github:kosinix/pigura

Tied to a specific version/release from GitHub:

npm install github:kosinix/pigura#1.0.0

Quickstart

You only need to provide 3 parameters:

• configName - The path to your config file relative to your app's root dir

• appDir - App's root dir

• env - The env variable. The default value is "dev". Any other value will load the config file + config.env file. See Convention.

• logging (optional) - true to use console.log

    const pigura = require('pigura');
  
    let configLoader = new pigura.ConfigLoader({ 
        configName: './config.json',
        appDir: path.resolve(__dirname),
        env: 'dev'
    })
  
    let config = configLoader.getConfig();
    console.log(config)
  

Examples

The recommended way to switch between environments is to use NODE_ENV. There are other ways as well but pigura does not care how you get the env variable.

Production Environment using NPM Script

In your package.json scripts section

{
    ...
    "scripts": {
        "prod": "set NODE_ENV=prod&& node index.js",
    }
    ...
}

In the command line you type:

npm run prod

Then in your main file:

let configLoader = new pigura.ConfigLoader({ 
    configName: 'config.json',
    appDir: path.resolve(__dirname),
    env: process.env.NODE_ENV // Pass to pigura
})
let config = configLoader.getConfig();
console.log(config)

This will:

• Read the contents of config.json
• Read config.prod.json and merged it with config.json. The same settings in config.prod.json will override the settings in config.json

Get Base Config Only

You can get the base config only, disregarding the env variable, and child configs:

let config = configLoader.getConfig(true);

Convention

Naming

Base config:

`${configName}.json` - config.json

Child configs:

`${configName}.${env}.json` - config.sandbox.json

Why "." as separator for env?

So you can name your configs with dash separators:

config-foo-bar.json
config-foo-bar.sandbox.json
config-foo-bar.prod.json

Or:

configFooBar.json
configFooBar.sandbox.json
configFooBar.prod.json

Test

Install mocha globally

npm install mocha -g

Run test

npm test
