gulp-css-urlversion

Plugin inlines md5-based version of url() resources in css files to force web browsers to fetch updated resources only.

Install

$ npm install --save-dev gulp-css-urlversion

Usage

Example css/sass source:

.royal_button {
    background: url(/images/bg-royal-button.png) 0 0 no-repeat;
    width: 14px;
    height: 14px;
    cursor: pointer;
}

output css:

.royal_button {
    background: url(/images/bg-royal-button.png?v=aa73ac3b951818635c87dc4f56e9cc97) 0 0 no-repeat;
    width: 14px;
    height: 14px;
    cursor: pointer;
}

gulpfile.js:

var gulp = require('gulp'),
    sass = require('gulp-sass'),
    sourcemaps = require('gulp-sourcemaps'),
    cssUrlVersion = require('gulp-css-urlversion');

gulp.task('sass', function () {
    gulp.src('./sass/*.scss')
        .pipe(sourcemaps.init())
        .pipe(sass({errLogToConsole: true}))
        .pipe(cssUrlVersion({baseDir: './static/www/'}))
        .pipe(sourcemaps.write('../maps/newthemes/'))
        .pipe(gulp.dest(_csspath + 'css/'));
});

###Options

baseDir - root for root-relative url() resources that you want to version. By default - process.cwd() is used as a root for root-relative resources.
