Bem-config NPM

bem-config

Usage

var bemConfig = require('bem-config');
var optionalConfig = { plugins: { create: { techs: ['styl', 'browser.js'] } } };
var projectConfig = bemConfig(optionalConfig); // returns BemConfig instance

options

All options are optional:

name // base name for rc files. Default value is bem.
cwd // Default value is process.cwd().
defaults // extends found configs with this object
pathToConfig // custom path to config on FS
fsRoot // custom '/' directory
fsHome // custom $HOME directory
plugins // array of paths to plugings to require

Async API

config.get().then(function(conf) {
    console.log(conf); // config is a merge of CLI args + optionalConfig + all configs found by rc
});

level

var config = require('bem-config')();
config.level('path/to/level').then(function(levelConf) {
    console.log(levelConf); // merged level config
});

library

var config = require('bem-config')();
config.library('bem-components').then(function(libConf) {
    console.log(libConf); // library config
});

levelMap

var config = require('bem-config')();
config.levelMap().then(function(levelMap) {
    console.log(levelMap); // all levels hash with their options
});

module

var config = require('bem-config')();
config.module('bem-tools').then(function(bemToolsConf) {
    console.log(bemToolsConf); // merged config for required module
});

configs

var config = require('bem-config')();
config.configs().then(function(configs) {
    console.log(configs); // all found configs from all dirs
});
