I am using NPM in a WP project.
I already have a grunt task that compiles my separate SCSS files into CSS files and then minifies them into one default.min.css file when running grunt (that's good.)
My main issue is that I would like to include different npm packages such as fontawesome, bootstrap etc. where they also would be minified into that one minified min.css file, together with my own files.
I would also like to know how to do this for my own *.js files uglify'd with different packages i'm using (jquery-ui, owl-carousel, etc.)
Please find below my Gruntfile.js, this is my first Gruntfile.js so feel free to include any constructive remarks.
Thanks,
Bud
Gruntfile.js
module.exports = function (grunt) {
grunt.initConfig({
sass: {
dist: {
files: [{
expand: true,
cwd: 'resource/scss/',
src: ['*.scss'],
dest: 'resource/builds/css/',
ext: '.css'
}]
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['sass', 'cssmin']
},

}]
}
}
});
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-concat');
grunt.loadNpmTasks('grunt-contrib-cssmin');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default',['cssmin', 'uglify', 'watch']);
};
For the last few days my grunt copy task is missing out some files. The task itself is the unedited task from SailsJS:
module.exports = function(grunt) {
grunt.config.set('copy', {
dev: {
files: [{
expand: true,
cwd: './assets',
src: ['**/*.!(coffee|less|scss|sass|js)'],
dest: '.tmp/public'
}]
},
build: {
files: [{
expand: true,
cwd: '.tmp/public',
src: ['**/*'],
dest: 'www'
}]
}
});
grunt.loadNpmTasks('grunt-contrib-copy');
};
I'm using Bower for dependencies within my assets folder which are copied to .tmp/public by Grunt.
Some facts:
it's always the same files which are missing (lib/marked.js, angular-elastic/elastic.js, angular-ui-select/dist/select.js, angular-slugify/angular-slugify.js)
it worked for quite some time - I didn't change anything in the task, just in the assets (but not in the vendor) folder.
grunt copy --verbose also doesn't list these files.
OS is win10.
New to gruntjs and currently using it for moving some npm distributions to a public/js folder.
Here is the code:
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
copy: {
bootstrapCss: {
src: "./node_modules/bootstrap/dist/css/bootstrap.css",
dest: "./public/css/bootstrap.css"
},
bootstrapTheme: {
src: "./node_modules/bootstrap/dist/css/bootstrap-theme.css",
dest: "./public/css/bootstrap-theme.css"
},
bootstrap: {
src: "./node_modules/bootstrap/dist/js/bootstrap.js",
dest: "./public/js/libs/bootstrap.js"
},
backbone: {
src: "./node_modules/backbone/backbone.js",
dest: "./public/js/libs/backbone.js"
},
backboneLocalstorage: {
src: "./node_modules/backbone.localstorage/backbone.localStorage.js",
dest: "./public/js/libs/backbone.localStorage.js"
},
requireJs: {
src: "./node_modules/requirejs/require.js",
dest: "./public/js/libs/requirejs.js"
},
underscore: {
src: "./node_modules/underscore/underscore.js",
dest: "./public/js/libs/underscore.js"
},
jquery: {
src: "./node_modules/jquery/dist/jquery.js",
dest: "./public/js/libs/jquery.js"
},
requireJsText: {
src: "./node_modules/requirejs-text/text.js",
dest: "./public/js/libs/requirejs-text.js"
}
}
});
// Load the plugin that provides the "uglify" task.
grunt.loadNpmTasks('grunt-contrib-copy');
// Default task(s).
grunt.registerTask('default', ['copy']);
};
Is there any way to make this code smaller, rather than have lots of individual copy commands?
Thanks
I would go about this by creating two targets in my copy configuration, one for JS and one for CSS. I would use some of the features provided by Grunt for dynamically building the files object to save me from typing and maintaining each destination path. This way, when I want to add files, I need only add their paths to the respective src array.
grunt.initConfig({
copy: {
js: {
expand: true,
cwd: './node_modules',
dest: './public/js/libs/',
flatten: true,
filter: 'isFile',
src: [
'./bootstrap/dist/js/bootstrap.js',
'./backbone/backbone.js',
'./backbone.localstorage/backbone.localStorage.js',
'./requirejs/require.js',
'./underscore/underscore.js',
'./jquery/dist/jquery.js',
'./requirejs-text/text.js'
]
},
css: {
expand: true,
cwd: './node_modules',
dest: './public/css/',
flatten: true,
filter: 'isFile',
src: [
'./bootstrap/dist/css/bootstrap.css',
'./bootstrap/dist/css/bootstrap-theme.css'
]
}
}
});
Grunt's dynamically built files objects is in the structure of:
files: [
{
expand: true, // Enable dynamic expansion.
cwd: 'lib/', // Src matches are relative to this path.
src: ['**/*.js'], // Actual pattern(s) to match.
dest: 'build/', // Destination path prefix.
ext: '.min.js', // Dest filepaths will have this extension.
extDot: 'first' // Extensions in filenames begin after the first dot
},
]
But this format does not work in grunt-injector:
injector: {
options: {
destFile : 'app/static/index.html',
ignorePath: 'app/'
},
local_dependencies: {
files: [
expand: true,
cwd: 'app/static/css/',
src: ['*.css'],
dest: '/static/css',
ext: '.css'
]
}
},
Any suggestions on how I can use Grunt's specific 'dynamically built files objects' with it?
If anyone has this issue, I guess you can not use sub categories like local_dependencies.
This worked for me:
injector: {
options: {
destFile : 'app/static/index.html',
ignorePath: 'app/'
},
files: {
expand: true,
cwd: 'app/static/css/',
src: ['*.css'],
dest: 'app/static/css',
ext: '.css'
}
},
there are some js files in static/js/
1. a.js
2. b.js
3. c.js
how to config grunt.js to get below files:
1. a.min.js
2. b.min.js
3. c.min.js
as far, I have to type specific file name:
min: {
dist: {
src: 'js/**/*.js',
dest: 'js/min/xxx.min.js'
}
}
Had the same problem and found a solution that would automatically minify all my scripts separately:
uglify: {
build: {
files: [{
expand: true,
src: '**/*.js',
dest: 'build/scripts',
cwd: 'app/scripts'
}]
}
}
In grunt 0.4 you can specify multiple dest/src pairs like this:
uglify: {
dist: {
files: {
'dist/main.js': 'src/main.js',
'dist/widget.js': 'src/widget.js'
}
}
}
Or you can use expandMapping, like this:
min: {
files: grunt.file.expandMapping(['path/*.js', 'path2/*.js'], 'destination/', {
rename: function(destBase, destPath) {
return destBase+destPath.replace('.js', '.min.js');
}
})
}
And the output:
path/test.js => destination/path/test.min.js
path2/foo.js => destination/path2/foo.min.js
This below gruntjs works for me for creating minified files for all the js files under a dir
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uglify: {
build: {
files: [{
expand: true,
src: '**/*.js',
dest: 'build/scripts',
cwd: 'public_html/app',
ext: '.min.js'
}]
}
}
});
// Load the plugin that provides the "uglify" task.
grunt.loadNpmTasks('grunt-contrib-uglify');
// Default task(s).
grunt.registerTask('default', ['uglify']);
};
From the grunt docs for min:
This task is a multi task, meaning that grunt will automatically
iterate over all min targets if a target is not specified.
So you can do this:
min: {
min_a: {
src: 'a.js',
dest: 'a.min.js'
},
min_b: {
src: 'b.js',
dest: 'b.min.js'
},
min_c: {
src: 'c.js',
dest: 'c.min.js'
}
There's nothing special about the name 'dist' for these tasks.
Use the ext option to name the files .min.js instead of .js
uglify: {
build: {
files: [{
expand: true,
src: '**/*.js',
dest: 'build/scripts',
cwd: 'app/scripts',
ext: '.min.js'
}]
}
}
For explicitly export some files into separate output files (in this case all.min.js and all.jquery.js) use:
uglify: {
js: {
files : {
'js/all.min.js' : [
'js/modernizr.js',
'js/vendor/modernizr-2.6.2-respond-1.1.0.min.js',
'js/bootstrap.min.js',
'js/main.js',
'js/ZeroClipboard.min.js',
'js/bootstrap-datepicker/bootstrap-datepicker.js'
],
'js/all.jquery.js' : [
'js/vendor/jquery-1.9.1.js',
'js/vendor/jquery-migrate-1.2.1.js',
'js/vendor/jquery-ui.js'
]
}
},
options: {
banner: '\n/*! <%= pkg.name %> <%= grunt.template.today("dd-mm-yyyy") %> */\n',
preserveComments: 'some',
report: 'min'
}
},
I like to keep the original files and also create uglified ones:
uglify: {
dist: {
files: [{
expand: true,
src: '**/*.js',
dest: 'destdir',
cwd: 'srcdir',
rename: function(dest, src) { return dest + '/' + src.replace('.js', '.min.js'); }
}]
}
},
You also can use copy and grunt-mindirect.
copy: {
dist: {
src: 'a.js',
dest: 'a.min.js'
}
},
minidirect: {
all: 'js/min/*.min.js'
}
This should work.
I guess it only matters for watch tasks.
In grunt 0.4 you can do this
var filesA = 'a.js', filesB = 'b.js', filesC = 'c.js';
...
min: {
min_a: {
src: filesA,
dest: 'a.min.js'
},
min_b: {
src: filesB,
dest: 'b.min.js'
},
min_c: {
src: filesC,
dest: 'c.min.js'
}
watch: {
min_a: {
files: filesA,
tasks: ['min:min_a']
},
min_b: {
files: filesB,
tasks: ['min:min_b']
},
min_c: {
files: filesC,
tasks: ['min:min_c']
}
}
After that just start grunt watch and all will be fine automagically.
In an intention to help others who come to this page in future -
I came across a video which explains on how to minify JS files using Grunt JS here: https://www.youtube.com/watch?v=Gkv7pA0PMJQ
The source code is made available here: http://www.techcbt.com/Post/359/Grunt-JS/how-to-minify-uglify-javascript-files-using-grunt-js
Just in case, if the above links are not working:
You can minify all javascript files and combine/concat into one file using the following script:
module.exports = function(grunt){
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uglify:{
t1:{
files:{
'dest/all.min.js': ['src/app.js', 'src/one.js', 'src/t/two.js']
}
}
}
});
};
If you would like to have source maps also generated, you can enable "sourceMap" option as follows:
module.exports = function(grunt){
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uglify:{
t1:{
options : {
sourceMap : true,
},
files:{
'dest/all.min.js': ['src/app.js', 'src/one.js', 'src/t/two.js']
}
}
}
});
};
In order to retain entire folder structure while minifying JS files, you can use the following script:
module.exports = function(grunt){
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
uglify:{
t1:{
files: [{
cwd: 'src/',
src: '**/*.js',
dest: 'dest/',
expand: true,
flatten: false,
ext: '.min.js'
}]
}
}
});
};
