grunt-contrib-uglify

I have a grunt tasks to concat and minify all my javascript files into one single file and the javascript file is in dist folder. "dist/<%= pkg.name %>.min.js'" "Gruntfile.js" module.exports = function (grunt) { grunt.initConfig({ pkg: grunt.file.readJSON("package.json"), concat: { options: { separator: ';' }, dist: { src: ['src/main/resources/app/js/**/*.js', 'src/main/resources/app/config/*.js', 'src/main/resources/app/app/js'], dest: 'dist/<%= pkg.name %>.js' } }, uglify: { options: { banner: '/*! <%= pkg.name %> <%= grunt.template.today("dd-mm-yyyy") %> */\n' }, dist: { files: { 'src/main

I'm using Grunt to concat and minify files (with grunt-contrib-uglify and grunt-contrib-concat ) and I wanted to add a source map. The uglify docs say to just add an option for sourceMap set to a boolean of true. But when I add that to my tasks (I've tried a couple different ones) the process runs fine until it gets to the source map part, then I get: Writing true...ERROR Warning: Unable to write "true" file (Error code: undefined). Use --force to continue. The concatenation is done, the minification is done. But... no luck with the sourcemap. Sample from my Grunt file: uglify: { options: {

I recently started using GruntJS through Yeoman and I like the idea of Javascript minification, but it presents difficulties during development. I tried to disable uglify,usemin, etc in different combinations in the Gruntfile but everything seems to be dependent on another thing and breaks the process. Is there a simple way to disable minification? I am using the latest versionof Grunt offered by Yeoman to date, I found that older solutions have a different Gruntfile setup than that usd with Yeoman. Here is my Gruntfile: // Reads HTML for usemin blocks to enable smart builds that automatically

I have been trying to install Grunt. When I run grunt I receive the following list of messages and warnings: Local Npm module "grunt-contrib-copy" not found. Is it installed?

Is there a way to combine and minify all bower installed libraries into 1 file automatically? First I tried the most basic approach: combine all .js files from all subdirectories: uglify: { options: {compress: true}, my_target: { files: { 'vendor.js': ['bower_components/**/*.js'], } } } But this is obviously a bad approach. It also doesn't work because of too many errors. I manually deleted all the files and kept only 1 (main) file that each library has, and it worked. Is there a way to do this all automatically? Also, is it advisable to do it? (i.e. combine all vendor libraries into 1 file) I

I'm using grunt-contrib's concat and uglify modules to process some javascript. Currently if src/js/ is empty, they will still create an (empty) concat'd file, along with the minified version and a source map. I want to task to detect if the src/js/ folder is empty before proceeding, and if it is, then the task should skip (not fail). Any ideas how to do this? The solution may not be the prettiest, but could give you an idea. You'll need to run something like npm install --save-dev glob first. This is based on part of the Milkshake project you mentioned. grunt.registerTask('build_js', function
