How do I replace the filenames listed in index.html with the output of gulp-rev?

Question

I\'m using gulp-rev to build static files that I can set to never expire. I\'d like to replace all references to the generated files in index.html to these renamed files, but I

You could do it with gulp-useref like this.

var gulp = require('gulp'),
    useref = require('gulp-useref'),
    filter = require('gulp-filter'),
    uglify = require('gulp-uglify'),
    minifyCss = require('gulp-minify-css'),
    rev = require('gulp-rev');

gulp.task('html', function () {
    var jsFilter = filter('**/*.js');
    var cssFilter = filter('**/*.css');

    return gulp.src('app/*.html')
        .pipe(useref.assets())
        .pipe(jsFilter)
        .pipe(uglify())
        .pipe(rev())
        .pipe(jsFilter.restore())
        .pipe(cssFilter)
        .pipe(minifyCss())
        .pipe(rev())
        .pipe(cssFilter.restore())
        .pipe(useref.restore())
        .pipe(useref())
        .pipe(gulp.dest('dist'));
});

or you could even do it this way:

gulp.task('html', function () {
    var jsFilter = filter('**/*.js');
    var cssFilter = filter('**/*.css');

    return gulp.src('app/*.html')
        .pipe(useref.assets())
        .pipe(rev())
        .pipe(jsFilter)
        .pipe(uglify())
        .pipe(jsFilter.restore())
        .pipe(cssFilter)
        .pipe(minifyCss())
        .pipe(cssFilter.restore())
        .pipe(useref.restore())
        .pipe(useref())
        .pipe(gulp.dest('dist'));
});

The problem is updating the asset paths in the html with the new rev file paths. gulp-useref doesn't do that.

This helped me gulp-html-replace.

 <!-- build:js -->
    <script src="js/player.js"></script> 
    <script src="js/monster.js"></script> 
    <script src="js/world.js"></script> 
<!-- endbuild -->
    var gulp = require('gulp');
    var htmlreplace = require('gulp-html-replace');

    gulp.task('default', function() {
      gulp.src('index.html')
        .pipe(htmlreplace({
            'css': 'styles.min.css',
            'js': 'js/bundle.min.js'
        }))
        .pipe(gulp.dest('build/'));
    });

I've just written a gulp plugin to do this, it works especially well with gulp-rev and gulp-useref.

The usage will depend on how you've set things up, but it should look something like:

gulp.task("index", function() {
  var jsFilter = filter("**/*.js");
  var cssFilter = filter("**/*.css");

  return gulp.src("src/index.html")
    .pipe(useref.assets())
    .pipe(jsFilter)
    .pipe(uglify())             // Process your javascripts
    .pipe(jsFilter.restore())
    .pipe(cssFilter)
    .pipe(csso())               // Process your CSS
    .pipe(cssFilter.restore())
    .pipe(rev())                // Rename *only* the concatenated files
    .pipe(useref.restore())
    .pipe(useref())
    .pipe(revReplace())         // Substitute in new filenames
    .pipe(gulp.dest('public'));
});

Rather than trying to solve this problem multiple gulp steps (which gulp-rev seems to want you to do), I've forked gulp-rev to gulp-rev-all to solve this usecase in one gulp plugin.

For my personal usecase I wanted to rev absolutely everything but as someone else raised an feature request, there should be the ability to exclude certain files like index.html. This will be implemented soon.

Answer 5

I have confronted the same problem, I tried gulp-rev-all, but it has some path problem, not very free to use.

So I figure out an solution, use gulp-rev and gulp-replace:

At first I have a replace symbol in my html(js, css) files

<link rel="stylesheet" href="{{{css/common.css}}}" />

<script src="{{{js/lib/jquery.js}}}"></script>

in css files

background: url({{{img/logo.png}}})

Second after some compile task, use gulp-replace to replace all the static files reference:

take stylus compile in development as example:

gulp.task('dev-stylus', function() {
   return gulp.src(['./fe/css/**/*.styl', '!./fe/css/**/_*.styl'])
             .pipe(stylus({
               use: nib()
             }))
             .pipe(replace(/\{\{\{(\S*)\}\}\}/g, '/static/build/$1'))
             .pipe(gulp.dest('./static/build/css'))
             .pipe(refresh());
});

In production environment, use gulp-rev to generate rev-manifest.json

gulp.task('release-build', ['release-stylus', 'release-js', 'release-img'], function() {
  return gulp.src(['./static/build/**/*.css',
                   './static/build/**/*.js',
                   './static/build/**/*.png',
                   './static/build/**/*.gif',
                   './static/build/**/*.jpg'],
                   {base: './static/build'})
             .pipe(gulp.dest('./static/tmp'))
             .pipe(rev())
             .pipe(gulp.dest('./static/tmp'))
             .pipe(rev.manifest())
             .pipe(gulp.dest('./static'));
});

Then use gulp-replace to replace the refs in static files with rev-manifest.json:

gulp.task('css-js-replace', ['img-replace'], function() {
  return gulp.src(['./static/tmp/**/*.css', './static/tmp/**/*.js'])
             .pipe(replace(/\{\{\{(\S*)\}\}\}/g, function(match, p1) {
               var manifest = require('./static/rev-manifest.json');
               return '/static/dist/'+manifest[p1]
             }))
             .pipe(gulp.dest('./static/dist'));
});
