gulp-md5-replace

md5 plugin for gulp ,md5 the static files(eg javascript style image files) ;then replace the filenames in css or the html if needed by passing the file or dir in the first parameter, if you want to replace the encrypted filenames to newly generated encrypted filenames or you want to specify the length of md5 filename, you can passing an opts object in the second parameter.

Usage

First, install gulp-md5-replace as a development dependency:

npm install --save-dev gulp-md5-replace

Then, add it to your gulpfile.js:

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

gulp.src("./src/*.css")
	.pipe(md5('./output/index.html', {length: 10, isEncrypted: true}))
	.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(quoteSrc, {isEncrypted: true}))
        .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(file, opts)

file

Type: String Default: null

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

opts

Type: Object Default: null

Optionnal: you can pass the length to limit the length of the hash that is appended and the isEncrypted to replace the specific filenames or encrypted filenames

Example:

	gulp.src('static/js/*')
        .pipe(md5('./output/html', {length: 10, isEncrypted: true}))
        .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.

Thank You
