gulp-bem

This package provides simple and clear tools to build your BEM project with simple deps.js support.

Usage

Building CSS for BEM project:

var gulp    = require('gulp');
var bem     = require('gulp-bem');
var concat  = require('gulp-concat');

var levels = ['base', 'blocks'];
var tree = bem(levels);

tree.deps('blocks/page')
    .pipe(bem.src('{bem}.css'))
    .pipe(concat('index.css'))
    .pipe(gulp.dest('./dist'));

Pretty easy, eh, mate?

Take a look at getbem.com as example of full-featured web site created with BEM and gulp-bem-stub as starting template for projects!

API

bem(levels, [options])

Creates function, that used for resolving dependencies in BEM project. Returns deps function.

levels

Type: Array or String
Default: process.cwd()

Contains array of Levels. They will be used in searching for requested blocks and ordering blocks with same names in different levels.

options

Type: Object

Options, that passed to bem-naming.

bem.src(glob)

This method consumes stream of BEM objects and searches files by glob pattern in them.

All files, that contained under BEM object path, following some convention about naming. Often CSS file have name of block and added .css suffix. If BEM object describes block with modificators, then it can be block_mod_value.css. You can read about naming and directory structure at getbem.com, if there are questions about it.

glob

Type: String or Array

Same as in gulp.src method, but with some interpolation happening. To provide BEM name generation - bem.src will substitute (with supplant syntax) all properties in BEM object.

gulp-bem-debug - nice output for BEM objects in stream.
gulp-bem-specs - specifications, that used in gulp-bem.
gulp-bem-pack - packing JavaScript CommonJS files with browserify.
