Config Weaver

A simple module to support overriding config files using environment variables.

Getting Started

Install this grunt plugin next to your project's Gruntfile.js with:

npm install config-weaver --save-dev

Then add this line to your project's Gruntfile.js gruntfile:

grunt.loadNpmTasks('config-weaver');

Documentation

• the root of the client project should contain a config file named config.yaml This file should be a valid YAML file containing at least an application.name plus any values that need to be externalised an under the control of infrastructure, for example:

application:
  name: myproj     
database:
  connectionString: jdbc:postgresql://hostname:5432/dbname

• Values can be overridden via environment variables, for example:

     myproj_database_connectionString=jdbc:postgresql://hostname/newdbname

• The following code allows you to access the effective config:

var conf = require('config-weaver').config();

• This grunt task will log what the effective config would be if the application is run:

grunt show-effective-config
