rework-class-prefix

rework-class-prefix Build Status

Add a class prefix to further sandbox CSS styling for third-party imports.

This comes in handy when you want to import two different CSS modules that might have conflictings styles. For example, if module A and module B both have a .media class selector that have different use cases, you can run them through rework-class-prefix and result in something like .a-media and .b-media.

Example input

.grid { /* ... */ }
.grid-row { /* ... */ }
.grid-row-col { /* ... */ }

Example output classPrefix('flx-')

.flx-grid { /* ... */ }
.flx-grid-row { /* ... */ }
.flx-grid-row-col { /* ... */ }

Installation

npm install --save rework-class-prefix

Usage

var fs        = require('fs'),
    rework    = require('rework'),
    classPrfx = require('rework-class-prefix');
 
var css = fs.readFileSync('css/my-file.css', 'utf8').toString();
var out = rework(css).use(classPrfx('my-prefix-')).toString();

In a gulpfile

var gulp        = require('gulp'),
    name        = require('gulp-rename'),
    rework      = require('gulp-rework'),
    reworkNPM   = require('rework-npm'),
    classPrefix = require('rework-class-prefix');
 
gulp.task('css', function() {
  return gulp.src('index.css')
    .pipe(rework(reworkNPM(), classPrefix('prfx-')))
    .pipe(name('index-prefixed.css'))
    .pipe(gulp.dest('css'));
});

Using the ignored option

var fs        = require('fs'),
rework    = require('rework'),
classPrfx = require('rework-class-prefix');
 
var css = fs.readFileSync('css/my-file.css', 'utf8').toString();
var out = rework(css).use(
            classPrfx('my-prefix-', { ignored: [/\.ng-/, 'some-class-to-ignore'] })
