我需要更改我的 uglify 任务的配置,仅根据需要缩小文件(如这里对 jshint 任务的解释:https ://github.com/gruntjs/grunt-contrib-watch#compiling-files-as-needed )
该修改适用于 jshint 任务,但不适用于 uglify,我认为问题在于属性路径......
任何帮助,将不胜感激 ;)
这是我的 Gruntfile.js :
module.exports = function (grunt) {
grunt.initConfig({
// define source files and their destinations
jshint: {
all: ['dev/**/*.js'],
},
uglify: {
dynamic_mappings: {
// Grunt will search for "**/*.js" under "dev/" when the "minify" task
// runs and build the appropriate src-dest file mappings then, so you
// don't need to update the Gruntfile when files are added or removed.
files: [{
expand: true, // Enable dynamic expansion.
cwd: 'dev/', // 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.
},
],
}
}
watch: {
options: { spawn: false },
js: { files: 'dev/**/*.js', tasks: [ 'uglify' ] },
}
});
// load plugins
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-contrib-jshint');
// default task
grunt.registerTask('default', [ 'watch' ]);
grunt.event.on('watch', function(action, filepath) {
grunt.config(['jshint', 'all'], filepath);
grunt.config('uglify.dynamic_mappings.files', [{src: filepath }]);
});
};
