I just downloaded a fresh copy of yeoman. When I build using grunt, I see that all my images have been converted and their file names have been renamed.
However, the references in the html file do not reference the new names.
Any idea why?
imagemin: {
dist: {
files: [{
expand: true,
cwd: '<%= yeoman.app %>/img',
src: '{,*/}*.{png,jpg,jpeg}',
dest: '<%= yeoman.dist %>/img'
}]
}
},
usemin: {
html: ['<%= yeoman.dist %>/{,*/}*.html'],
css: ['<%= yeoman.dist %>/styles/{,*/}*.css'],
options: {
dirs: ['<%= yeoman.dist %>']
}
},
ngapp/views/main.html
Renaming is done by the grunt-filerev task in your Gruntfile. The usemin task takes care of updating the references to those renamed files for scripts, stylesheets and images, but doesn't support inline styles. You should either move the background-image reference within a stylesheet or disable the rev task.
The problem is probably that your url for the image in your HTML file is a relative path and and usemin can't resolve the new path of the image to your url. See #eddiemonge comment on github for a better explanation: https://github.com/yeoman/grunt-usemin/issues/108
I had the same problem and fixed it by using a fixed path (/img/demo/red-green.png, in your case) which works fine as long as your distribution directory uses /img and img is also off the root of your app when doing development.

We are trying to compile our sass files to css files, however we want to compile each individual sass file into an individual css file (one-to-one).
For example our product_view.scss should have a product_view.css.
However all configurations we have tried create one css file for everything called styles.css in our "out/css" folder.
sass: {
dist: {
options: {
compass: true,
style: 'expanded'
},
files: [{
expand: true,
cwd: '<%= pkg.src %>/assets/sass',
src: ['*.scss'],
dest: '<%= pkg.src %>/assets/media/out/css',
ext: '.css'
}]
},
},
I use grunt-contrib-compass (Compass) to compile my SASS, which has some nice extras. For example, compass includes a reset utility you can use by using
#import 'compass/reset';
But disregarding that, compass also outputs every file individually (as long as it does not start with _ which are files that can be included but won't be compiled by themselves). Here is the setup I use in my gruntfile:
compass: {
'default': {
options: {
sassDir: "css/sass/",
cssDir: "css/",
outputStyle: "compressed"
}
}
}
I have a Yeoman project scaffolded with 'webapp-generator' which contains a static website with nested HTML files, resembling this structure:
-root/
index.html
-directory/
file1.html
-directory2/
file2.html
-js/
(revved .js files)
-css
(revved .css files)
I'm using usemin and filerev tasks to update the filerevved file paths on the .html documents. It updates all file names correctly on js/css/images and it works correctly on the root index.html.
However, on the nested HTML files, it doesn't replace the reference to the correct nested path.
For example.
js/scripts.js gets renamed to js/827385.scripts.js
In index.html
<scripts src="js/scripts.js"></scripts>
resolves to: <scripts src="js/827385.scripts.js"></scripts>
But in directory/file1.html (or any other nested html file)
<scripts src="../js/scripts.js"></scripts>
gets also converted to: <scripts src="js/827385.scripts.js"></scripts>
Ignoring the ../ relative path
Is there any way to tweak the Grunt tasks to be aware of the relative depth of the file within the directories to keep the relative indicator ../ in the renamed path?.
Below is the code snippet for the relevant Grunt tasks.
PS: I have already followed some of the possible answers in this Stack Overflow question: How should I configure grunt-usemin to work with relative path to no avail.
// Renames files for browser caching purposes
rev: {
dist: {
files: {
src: [
'<%= config.dist %>/scripts/{,**/}*.js',
'<%= config.dist %>/styles/{,**/}*.css',
'<%= config.dist %>/images/{,**/}*.*',
'<%= config.dist %>/styles/fonts/{,**/}*.*',
'<%= config.dist %>/*.{ico,png}'
]
}
}
},
// Reads HTML for usemin blocks to enable smart builds that automatically
// concat, minify and revision files. Creates configurations in memory so
// additional tasks can operate on them
// <%= config.dist %>
useminPrepare: {
options: {
dest: 'out',
// root: '<%= config.app %>'
},
html: '<%= config.app %>/index.html'
// root: '<%= config.app %>'
},
// Performs rewrites based on rev and the useminPrepare configuration
usemin: {
options: {
assetsDirs: [
'<%= config.dist %>',
'<%= config.dist %>/images',
'<%= config.dist %>/styles'
]
},
html: ['<%= config.dist %>/**/*.html'],
css: ['<%= config.dist %>/styles/**/*.css']
},
In my case I've found out that the problem was usemin configuration in the html files:
If you have in your index.html this usemin directive:
<!-- build:js styles/jquery.js -->
<script src="bower_components/jquery/dist/jquery.js"></script>
<!-- endbuild -->
In directory/file1.html you should try to use a full path in it:
<!-- build:js /scripts/jquery.js-->
<script src="../bower_components/jquery/dist/jquery.js"></script>
<!-- endbuild-->
which will be converted to something like <script src="/scripts/jquery.34ad31c3.js"></script>.
I am using yeoman webapp to scaffold a basic application. I use bower install --save to install a couple of libraries which make their way into bower_components folder. Now I run grunt build and to my surprise the index.html file in the dist folder refers to the bower_components folder for the js files. I had expected the build process to automatically concatenate these files and put the concatenated script in the dist folder and make the index.html file refer to this concatenated file. What should I do to make this happen by default.
Just facing the same issue on one of my project, a warning because of a bad file targeter was stopping the grunt build, and since the usemin task is the last to be run, my scripts was perfectly concatenated and minified, but the references in my html was not updated.
If you have like me an error, try to fix it or to run a grunt build --force to pass it.
If no, check that your scripts are correctly surrounded by the build tags
<!-- build:js({.tmp,app}) scripts/vendor.js -->
...
<!-- endbuild -->
And that you have correctly configure your rev, useminPrepare and usemin tasks
Little exemple :
rev: {
dist: {
files: {
src: [
'<%= yeoman.dist %>/public/scripts/{,*/}*.js',
'<%= yeoman.dist %>/public/styles/{,*/}*.css'
]
}
}
},
useminPrepare: {
html: '<%= yeoman.app %>/views/index.html',
options: {
dest: '<%= yeoman.dist %>/public'
}
},
usemin: {
html: '<%= yeoman.dist %>/views/{,*/}*.html',,
css: ['<%= yeoman.dist %>/public/styles/{,*/}*.css'],
options: {
assetsDirs: ['<%= yeoman.dist %>/public']
}
},
Also ensure that your build task is referencing to them :
grunt.registerTask('build', [
'clean:dist',
'bower-install',
'useminPrepare',
'concurrent:dist',
'autoprefixer',
'concat',
'ngmin',
'copy:dist',
'cdnify',
'cssmin',
'uglify',
'rev',
'usemin'
]);
I'm building a site using the Yeoman generator: https://github.com/Thomas-Lebeau/generator-bootstrap-less.
I've installed fancybox using bower by doing the following:
bower install fancybox --save
add the fancybox script include into my usemin build block in index.html
#import "../bower_components/fancybox/source/jquery.fancybox.css"; into my only .less file
finally, copy across the fancybox vendor images using the following config in grunt's copy task.
code:
// Gruntfile.js
...
copy: {
dist: {
files: [{
expand: true,
dot: true,
cwd: '<%= yeoman.app %>',
dest: '<%= yeoman.dist %>',
src: [
'*.{ico,png,txt}',
'.htaccess',
'images/{,*/}*.{webp,gif}']
}, {
expand: true,
dot: true,
cwd: '<%= yeoman.app %>/bower_components/fancybox/source',
src: '**/*.{png,jpg,jpeg,gif}',
dest: '<%= yeoman.dist %>/bower_components/fancybox/source'
}]
},
...
(Sorry, don't know why the formatting is glitched there.. https://gist.github.com/ptim/8555923)
This is working for me, but I'd like to take it a step further to get a better understanding of what's going on. It's working simply because I'm replicating the relative path used in app/ when I copy.
What I'd like is to have the bower assets copied in with my other images, and the paths in my html rewritten (as happens with imagemin and usemin, etc)
....
}, {
expand : true,
dot : true,
cwd : '<%= yeoman.app %>/bower_components/fancybox/source',
src : '**/*.{png,jpg,jpeg,gif}',
dest : '<%= yeoman.dist %>/images'
}]
....
How do I achieve that using the conventions of this package?
(I've seen alternate suggestions: How to rewrite urls of images in vendor CSS files using Grunt)
I've tried changing the dest: path, and adding flatten: true
Here's the trail I'm following:
grunt build finishes with copy, rev, usemin,
rev is adding a version number to the fancybox files
usemin is executes usemin:html and rewrites all the image filenames to match the rev'd files
usemin:css then runs, but doesn't list any rewrites, then grunt finishes:
Running "usemin:css" (usemin) task
Processing as CSS - dist/styles/cf3b732a.main.css
Update the CSS with new img filenames
Done, without errors.
Can anyone suggest a tweak for me?

I do not know how i can change my path using grunt tasks. I need to change my path for all files (css, js, images etc). I do not found any example how to do it ?
For example now grunt create something like that :
<script src="scripts/d41d8cd9.plugins.js"></script>
And i need something like that :
<script src="myapp/scripts/d41d8cd9.plugins.js"></script>
So i need to do it for dist , and for all path
OK. Think you need to update your rev configuration then.
rev: {
dist: {
files: {
src: [
'<%= yeoman.dist %>/myapp/scripts/{,*/}*.js',
'<%= yeoman.dist %>/myapp/styles/{,*/}*.css',
'<%= yeoman.dist %>/myapp/images/{,*/}*.{png,jpg,jpeg,gif,webp,svg}',
'<%= yeoman.dist %>/myapp/styles/fonts/*'
]
}
}
}
As of now there is no such grunt plugin exist, However I believe you can achieve the same by using grunt-string-replace plugin,
I am planning to work on similar plugin, which would make this task trivial
