I have a React app that I am transforming, uglifying and browserfying via Grunt. My grunt file looks like this...
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
browserify: {
dist: {
files: {
'./Scripts/build/App.js': ['./Scripts/src/**/*.js']
},
options: {
browserifyOptions: {
debug: true
},
transform: [ require('grunt-react').browserify ],
ignore: './Scripts/src/**/*-test.js'
}
}
},
uglify: {
my_target: {
files: {
'./Scripts/build/App-min.js': ['./Scripts/build/App.js']
}
}
},
watch: {
scripts: {
files: ['./Scripts/src/**/*.js'],
tasks: ['browserify', 'uglify'],
options: {
spawn: false
},
},
},
})
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-browserify');
grunt.loadNpmTasks('grunt-contrib-watch');
}
You will notice the ignore property of the browserify task is telling it to ignore any file with -test.js in the filename, the reason being that my tests are stored in folders directly next to the file I am testing (as seems to be the convention when looking at the React Flux examples) and I don't want the test files being bundled in to my app.js file. Can anyone tell me if I am doing this wrong because so far it doesnt seem to be working at all? The test files get bundled into app.js and then I get console errors about jest not being defined.
Did a bit of lateral Googling and found a post on stack Here
It seems that you can add files to the src array and if you prefix them with a '!' it marks them as ignored files.
My now working grunt file....
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
browserify: {
dist: {
files: {
'./Scripts/build/App.js': ['./Scripts/src/**/*.js', '!./Scripts/src/**/*-test.js']
},
options: {
browserifyOptions: {
debug: true
},
transform: [ require('grunt-react').browserify ]
}
}
},
uglify: {
my_target: {
files: {
'./Scripts/build/App-min.js': ['./Scripts/build/App.js']
}
}
},
jest: {
options: {
coverage: true,
testPathPattern: /.*-test.js/
}
},
watch: {
scripts: {
files: ['./Scripts/src/**/*.js'],
tasks: ['browserify', 'uglify'],
options: {
spawn: false
},
},
},
})
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-jest');
grunt.loadNpmTasks('grunt-browserify');
grunt.loadNpmTasks('grunt-contrib-watch');
}

I have a pretty basic setup with sass, watch and uglify but for some reason I can't get watch to detect when a js file is saved. It works fine for SCSS/CSS (compiles and reloads.) If I run 'grunt uglify' it bundles my JS files, and if watch is running (in another console instance) it will detect it and trigger the reload.
I've tried lots of combinations and I have a feeling it's something really dumb I'm doing/not doing but I'm just not seeing it.
my gruntfile.js:
module.exports = function(grunt) {
grunt.registerTask('default', ['sass', 'uglify']);
grunt.initConfig({
sass: {
dist: {
options: {
style: 'expanded'
},
files: { 'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/main.css': 'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/main.scss' }
}
},
uglify: {
my_target: {
files: {
'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/js/site.js': [
'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/lib/jquery/dist/jquery.js',
'fivesixtwo.com/src/FiveSixTwo.com/wwwroot/lib/*.js'
]
}
}
},
watch: {
options: {
livereload: 35729,
},
html: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/Views/*.cshtml'],
},
sass: {
options: {
livereload: false
},
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/*.scss'],
tasks: ['sass']
},
css: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/css/main.css'],
tasks: []
},
scripts: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/js/site.js'],
tasks: ['uglify']
}
}
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-sass');
grunt.loadNpmTasks('grunt-contrib-uglify');
};
Look at your watch config:
scripts: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/js/site.js'],
tasks: ['uglify']
}
You are only watching for a single js files changes called site.js. To watch all your sources use this config:
scripts: {
files: ['fivesixtwo.com/src/FiveSixTwo.com/wwwroot/lib/*.js'],
tasks: ['uglify']
}
Use the same pattern as in the uglify config. I assumed you are not going to modify jquery itself.
I can't figure out why jQuery is being ignored when running my Grunt task. Here is what it looks like:
module.exports = function (grunt) {
// Configuration
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
// Concat
concat: {
js: {
src: [
'js/vendor/jquery.js',
'js/app/graph.js',
],
dest: 'app/build/js/app.js'
}
},
// Uglify
uglify: {
options: {
preserveComments: false
},
my_target: {
files: {
'app/build/js/app.min.js': [
'app/build/js/app.js'
]
}
}
});
};
When I check app.js, jQuery is part of it, but not in app.min.js. So I suspect something is wrong with the Uglify part.
github.com/gruntjs/grunt-contrib-clean This is not strictly necessary, jQuery should be included if that's all you've got. Do a test on the included site to be sure it's not just hiding somewhere in the uglified code.
I don't think your syntax is right, please try instead this:
uglify: {
development: {
options: {
preserveComments: false
},
files: {
'app/build/js/app.min.js': 'app/build/js/app.js'
}
}
And call it as: grunt.registerTask('default', ['concat', 'uglify:development']);
Not sure if this will help at all or if there even is any difference between the two, but you could try setting up your uglify config similarly to your concat config... e.g:
module.exports = function (grunt) {
// Configuration
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
// Concat
concat: {
js: {
src: [
'js/vendor/jquery.js',
'js/app/graph.js',
],
dest: 'app/build/js/app.js'
}
},
// Uglify
uglify: {
options: {
preserveComments: false
},
js: {
src: ['app/build/js/app.js'],
dest: ['app/build/js/app.min.js']
}
}
});
};
Also, I think you were missing an extra bracket
Curious about whether there’s a way to use both Autoprefixer and Compass in Grunt without having to specify a different output path for each task.
I currently have my .scss files in a folder named source. The compass task compiles these into a folder named build. I want to then run Autoprefixer without having to specify another different output path (i.e. still be in the build directory).
Is it not possible to run Autoprefixer on a compass compiled CSS file without specifying a different output path? Is it possible to run both at the same time perhaps?
Here’s the section of my gruntfile it relates to if it’s of any help. What I run in terminal is grunt watch:
compass: {
options: {
sassDir: 'style/source',
cssDir: 'style/build',
outputStyle: 'expanded',
}
},
watch: {
css: {
files: ['style/source/**/*.scss'],
tasks: ['compass'],
options: {
spawn: false,
}
}
},
Refs:
https://github.com/nDmitry/grunt-autoprefixer
https://github.com/gruntjs/grunt-contrib-compass
If you do not specify an output location for Autoprefixer, it will just use the input location and overwrite the files. Here’s the updated section of the gruntfile if it’s of help to anyone:
autoprefixer: {
css: {
src: 'style/build/**.css',
}
},
watch: {
options: {
livereload: true,
},
css: {
files: ['style/source/**/*.scss'],
tasks: ['compass', 'autoprefixer:css'],
options: {
spawn: false,
}
}
}
You may also want to add map: true to the autoprefixer call.
Here is a working copy for your goal :
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
autoprefixer: {
css: {
src: 'css/*.css',
options: {
map: true
}
}
},
compass: {
css: {
options: {
config: 'config.rb'
}
}
},
watch: {
css: {
files: '**/*.scss',
tasks: ['compass:css', 'autoprefixer:css'],
options: {
interrupt: true
}
}
}
});
grunt.loadNpmTasks('grunt-autoprefixer');
grunt.loadNpmTasks('grunt-contrib-compass');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.registerTask('default', ['watch']);
};
I have recently discovered grunt as it is used within an opensource project I have started to work on. Having not worked with grunt before I am struggling to see how it works, or in my case doesn't.
The grunt file is supplied by the project and I assume it works for everyone else. I have installed grunt and the necessary grunt modules have all installed in the "Node_modules" directory.
When running the grunt file the first process performs a number of concatenations and this seems to work fine. The concatenated files are created.
All of the other steps do not seem to execute. The files they are intended to create are not created. There is no error message displayed on the console when grunt is executed.
I'm stumped - anyone have any clues what might be the problem.
The grunt file is :
/*global module:false*/

The output from the console is as follows :
Running "jshint:globals" (jshint) task
>> 0 files lint free.
Running "concat:dist" (concat) task
File "chrome/js/requester.js" created.
Running "concat:requester_html" (concat) task
File "chrome/requester.html" created.
Running "concat:requester_tester" (concat) task
File "chrome/tester.html" created.
Done, without errors.
Given that the tasks are defined like this:
grunt.registerTask('default', ['jshint', 'concat']);
grunt.registerTask('package', ['concat', 'handlebars', 'sass', 'compress']);
the output you show is what you'd expect if you are running grunt without a task name. It runs the jshint and concat tasks.
If you want to run the tasks associated with package, then you have to run grunt package to run those tasks.
It looks like I did not understand "tasks" within grunt.
Instead of executing "grunt" which runs the "default" tasks, I had to execute "grunt package" which runs the tasks that I was interested in.
As Louis said, you have to specify the right task to run.
But you can also create or modify the tasks you have in order to make it simpler. In your example you may include package in the default task. Because concat task is already executed inside package, you may just replace it in the default task:
grunt.registerTask('default', ['jshint', 'package']);
grunt.registerTask('package', ['concat', 'handlebars', 'sass', 'compress']);
and, in order to build your site, just type
grunt
both jshint and package tasks will be executed
I am having a go at grunt for optimizing my Durandal SPA. It seems to work great but now I would like to output a second file called libs.js which is the merged uglified version of all my required libraries but my first dist is getting ignored and still the only file I get is main-built.js
I only get one file so app/libs.js never gets created. I also have no grunt errors.
Here is my Gruntfile:
module.exports = function (grunt) {
grunt.initConfig({
durandal: {
libs: {
src: [
"../scripts/jquery-1.9.1.js",
"../scripts/typeahead.js",
"../scripts/jquery-ui-1.10.3.js",
"../scripts/knockout-3.0.0rc.js",
"../scripts/toastr.js",
"../scripts/q.js",
"../scripts/breeze.min.js",
"../scripts/bootstrap.js",
"../scripts/moment.js",
"../scripts/lodash.js",
"../scripts/respond.js",
"../scripts/knockout-sortable.js",
"../scripts/knockout-bootstrap.js",
"../scripts/knockout.validation.js",
],
dest: 'scripts/libs.js',
options: {
uglify2: {
compress: {
global_defs: {
DEBUG: false
}
}
}
}
},
dist: {
src: [
"app/**/*.*",
"scripts/durandal/**/*.*"
],
options: {
baseUrl: "app/",
mainPath: "app/main.js",
out: "app/main-built.js",
uglify2: {
compress: {
global_defs: {
DEBUG: false
}
}
}
}
}
}
});
grunt.loadTasks('tasks');
grunt.registerTask('default', ['durandal']);
};
This is JavaScript. If you create an object like { a: 'a', a: 'b' }, the first key will be overwritten by the second by the VM.
Instead of configuring it like this:
dist: {
// config goes here
},
dist: {
// config goes here
}
Try
libs: {
// config goes here
},
main: {
// config goes here
}
