lconf

lconf

parse local configuration files of various types. currently supported filetypes: json,yaml,yml,js (must module.exports = {};)

api

lconf supports three methods:

• parse(file:string):
  parses a configuration file located at file. note: file must be a path fs recognizes, so be sure to use ./ when needed.

• suppress(bool:boolean[default=true]):
  toggles throwing of exceptions when parsing. using suppress() will prevent throwing of errors.

• opts():
  does the actual parse, and throws errors if there are any, and we aren't suppress()-ed.

these methods can be chained together:

var lconf = require('lconf');

// parse multiple configuration files
var config = lconf().parse('./config.yaml').parse('./config.json').opts();

the resulting object will look like:

{
  "./config.yaml": {...},
  "./config.json": {...}
}

If you want to smash configuration variables into one object, see bengreenier/hulksmash.

examples

parse some config files that may or may not be present:

var lconf = require('lconf');

// parse multiple configuration files
var config = lconf()
              .parse('./idk.yaml')
              .parse('./if.json')
              .parse('./these.json')
              .parse('./are.json')
              .parse('./present.js')
              .suppress()
              .opts();

// could check config object keys to see what succeeded

reuse parsing instance:

var lconf = require('lconf');

// parse multiple configuration files
var parser = lconf();

var config = parser
              .parse('./config.yaml')
              .parse('./config.json')
              .opts();

var settings = parser
              .parse('./settings.yaml')
              .parse('./settings.json')
              .opts();

// config will have two keys (one for each .parse() filename)
// settings will have two as well.
// each call to .opts() clears previously parsed data
