<script src="/js/a.js?v=12f3243.js"></scripts>

Usage

First, install gulp-md5-plus-always as a development dependency:

npm install --save-dev gulp-md5-plus-always

Then, add it to your gulpfile.js:

var md5 = require("gulp-md5-plus-always");

gulp.src("./src/*.css")
	.pipe(md5(10,'./output/index.html'))
	.pipe(gulp.dest("./dist"));

md5 all css files in the src folder and change these css names in the quoted html--index.html

gulp.task('img' ,function() {
    var imgSrc = './static/img/**',
        quoteSrc = './output/static/css/**/*.css', // [./output/static/css/**/*.css',./output/static/js/**/*.js']
        imgDst = './output/static/img';

    return gulp.src(imgSrc)
        .pipe(imagemin())
        .pipe(md5(10 ,quoteSrc))
        .pipe(gulp.dest(imgDst));
});

first, optimize all images in the img folder including all sub folders; then md5 all these images and change these images' names in the quoted css files ;

####note the directory of the md5ed files in the imgDst folder is the same as that of original files in the imgSrc folder; and css files can refer the image file with the same name in different folder rightly;

API

md5(size,file)

size

Type: String Default: null

Optionnal: you can pass the size to limit the size of the hash that is appended.

file

Type: String Default: null

Optionnal: the file need to replace the file name of the md5ed files. dir is also supported

Example:

	gulp.src('static/js/*')
        .pipe(md5(10,'./output/html'))
        .pipe(gulp.dest('./output'));

The sample above will append the md5 hash(length : 10) to each of the file in the static/js folder then repalce the link file name in the output/html/ using md5ed file name; at last store all of that into the output folder.
