Grunt task duplicate key - javascript

I have a grunt file with tasks and jshint giving me a warning for duplicate keys on below:
clean: ['public', 'build', 'css/main.css', 'css/print.css'],
clean : {
aftertest :['js/libs']
},
How can I make this in one key, so that by default it runs ['public', 'build', 'css/main.css', 'css/print.css']?

You should use different targets for this.
grunt.initConfig({
clean: {
build: ['public', 'build', 'css/main.css', 'css/print.css'],
aftertest: ['js/libs']
}
});
Then in your build alias you might want to use it like so:
grunt.registerTask('build', ['clean:build', 'stylus', 'jade', 'jshint']);
Whenever you have more than a single target for one task, it's best to explicitly name them so that you'll know, in the future, what each target's purpose is.

The error it's because the object you are passing to grunt.initConfig has two keys with the same name.
This is a Gruntfile.js example for gjslint task
module.exports = function(grunt) {
// Project configuration.
grunt.initConfig({
watch: {
files: ['<%= jshint.files %>'],
tasks: ['jshint', 'qunit']
},
gjslint: {
options: {
flags: [
'--nojsdoc'
],
reporter: {
name: 'console'
}
},
app: {
src: ['www/app/**/*.js']
}
}
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-gjslint');
grunt.registerTask('build', 'Grunt build taskt...', function() {
grunt.log.write('you can log here some stuff...').ok();
});
};

Uglify not working with Grunt 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.

Using both Compass and Autoprefixer in Grunt

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']);
};

Gruntfile.js - Throwing error 'Recursive process.nextTick detected"

I have defined a simple Gruntfile.js per the official instructions and yet I am getting a warning when I run the grunt watch ('$ grunt watch') or grunt default task ('$ grunt ').
The error is:
(node) warning: Recursive process.nextTick detected. This will break
in the next version of node. Please use setImmediate for recursive
deferral.
I have read the related StackOverflow question and answer here: grunt throw "Recursive process.nextTick detected", but that didn't resolve my issue.
My Gruntfile.js is:
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
concat: {
options: {
separator: ';'
},
dist: {
src: ['client/app/**/*.js'],
dest: 'client/dist/<%= pkg.name %>.js'
}
},
uglify: {
options: {
banner: '/*! <%= pkg.name %> <%= grunt.template.today("dd-mm-yyyy") %> */\n'
},
dist: {
files: {
'dist/<%= pkg.name %>.min.js': ['<%= concat.dist.dest %>']
}
}
},
jshint: {
files: ['client/app/**/*.js', 'server/**/*.js'],
options: {
// options here to override JSHint defaults
globals: {
jQuery: true,
console: true,
module: true,
document: true
}
}
},
watch: {
files: ['<% jshint.files %>'],
tasks: ['jshint']
}
});
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-concat');
grunt.registerTask('default', ['watch']);
grunt.registerTask('test', ['jshint']);
grunt.registerTask('build-dev', ['jshint', 'concat']);
grunt.registerTask('build', ['jshint', 'concat', 'uglify']);
};
OK. I figured it out. And dagnabbit, the bug was in the same Gruntfile that I copied hither from thither.
Node did NOT like the watch instructions to reference the jshint.files property and then call the jshint task. So instead, I put the files in explicitly as follows. After changing the following lines (with context):
watch: {
files: ['client/app/**/*.js', 'server/**/*.js'],
tasks: ['jshint']
}
the grunt watch and default tasks (the default task was performing the watch task), it worked without any warnings!
So I know this question has been answered, but I'll share my insights into this error as it proved to be a colossal waste of time.
Here's my original Gruntfile:
module.exports = function (grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
watch: {
dev: {
files: ['**/*.js', 'public/stylesheets/**/*.scss'],
tasks: ['express:dev'],
options: {
spawn: false
}
}
},
express: {
dev: {
options: {
script: 'server.js',
node_env: 'development'
}
}
}
});
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-express-server');
grunt.registerTask('default', ['express:dev', 'watch']);
};
In a similar vain to Chad, I resolved the issue by removing js files from my watch task, which restarts Express. The below configuration of the aforementioned task works fine for me:
watch: {
dev: {
files: ['public/stylesheets/**/*.scss'],
tasks: ['express:dev'],
options: {
spawn: false
}
}
},

grunt watch & connect

I am kinda new to grunt and want to use it with Jekyll and some LESS-compiling.
My problem now is, I already have fully functioning LESS-comipiling with live reload and watch task and can build my jekyll site through grunt, but how do I run something like the jekyll serve or grunt-connect and grunt watch simultaneously?
I want a grunt task that provides the watching of my LESS-files etc, builds the jekyll site and then runs a small web server with grunt-connect or whatever.
My Gruntfile.js so far:
'use strict';
module.exports = function (grunt) {
grunt.initConfig({

}
},
serve: { // Another target
options: {

drafts: true
}
}
},
connect: {
server: {
options: {
keepalive: true
}
}
}
});
// Load tasks
grunt.loadNpmTasks('grunt-contrib-clean');
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-less');
grunt.loadNpmTasks('grunt-jekyll');
grunt.loadNpmTasks('grunt-contrib-connect');
// Register tasks
grunt.registerTask('default', [
'clean',
'less:dist',
'uglify',
'jekyll:dist'
]);
grunt.registerTask('dev', [
'watch'
]);
};
You need to tell connect what directory to serve up in the configuration using the "base" option, in this case it would be the static _site directory. You can also change the port to whatever you want, but you end up navigating to localhost:9009 with my example
connect: {
server: {
options: {
livereload: true,
base: '_site/',
port: 9009
}
}
}
You will also want to add a watch task for when you change your html templates. Something like this would work.
watch: {
html: {
files: ['**/*.html', '!_site/**/*.html'],
tasks: ['jekyll:dist']
}
}
Then create a "serve" task like Wallace suggested.
// Start web server
grunt.registerTask('serve', [
'jekyll:dist',
'connect:server',
'watch'
]);
Lastly run "grunt serve" in the command line and navigate to localhost with the port you specified.
As commented by #jiggy
The key change is to not set keepalive to true. Keepalive will block
all subsequent tasks from running. So long as connect is followed by
watch the server won't terminate.
I spent 2 days desperately trying every gruntfile-configuration I could find on the internet. Never worked. Then I found this https://stackoverflow.com/a/24765175/1541141.
Use grunt-contrib-connect, NOT grunt-connect. grunt-connect is blocking...
Hope it helps.
I think the heart of your solution is to create a new task or edit an existing task, like so:
// Start web server
grunt.registerTask('serve', [
'jekyll:dist',
'connect:livereload',
'watch'
]);
...which you would run with a $ grunt serve. less, jshint, uglify and connect are already included under watch.

Grunt file does not complete

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*/
module.exports = function(grunt) {
// Project configuration...

grunt.registerTask('default', ['jshint', 'concat']);
grunt.registerTask('package', ['concat', 'handlebars', 'sass', 'compress']);
};
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
