file-config-reader v0.1.1

file-config-reader

A simple module for reading and merging config files that are stored "locally" (current working tree) and "globally" (home directory).

This module was built primarily for use when writing command-line (CLI) programs in Node.js. It implements some features from a few of my favorite command-line applications:

• JSHint - looks for config files not just in the working directory, but also in parent directory.
• Git - looks for config files in both a "local" and "global" location.

Instead of passing options to the command-line, it's often beneficial to store program-specific options in a configuration file. Additionally, you may want to maintain project-specific configuration files and/or a global configuration file for shared cross-project settings (i.e. 'git'). Also, when working within subdirectories of a project folder, it's often useful for a command-line utility to search upwards in the directory tree for a configuration file, so you don't constantly need to navigate back to the location of the configuration file (i.e. JSHint).

Note: Currently, this module only supports files with JSON content.

Install

npm install file-config-reader --save

Usage

> pwd
/Users/andre/dev/projects/cli_reader

> cat conf.json
{
  "projectName": "cli_reader_sample",

{
  "firstName": "Andre",
  "lastName": "Giannico",
  "email": "andre@andregiannico.com",
  age: 31
}

var FileConfigReader = require('file-config-reader');

var conf = new FileConfigReader('conf.json');

console.log(conf.firstName);

// output
"Andre"

console.log(conf);

// output
{
  projectName: "cli_reader_sample",
