比如把coffee文件写在coffee/controller/文件夹下，新建js/controller文件夹，使用grunt运行项目，将自动编译coffee到相应的js文件夹下。
module.exports = function(grunt) {
// 项目配置信息.
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
jshint: {
options : {
jshintrc: '.jshintrc',
// eqeqeq: true,
// tradiling: true,
ignores: ['node_modules/**/*.js']
},
all: ['**/*.js']
},
coffee:{
compile: {
options: {
sourceMap: false,
bare: true
},
files: [{
expand: true,
cwd: "coffee/",
src: '**/*.coffee',
dest: 'js/',
ext: '.js'
}]
}
},
watch: {
coffee: {
files: ['**/*.coffee'],
tasks: ['coffee:compile']
// },
// js: {
// files: ['**/*.js'],
// tasks: ['jshint'],
// options: {
// livereload: true
// }
}
},
nodemon: {
dev: {
script: 'bin/www',
options: {
args: [],
ignoredFiles: [],
watchedExtensions: ['js'],
watchedFolders: ['./'],
debug: true,
delayTime: 1,
env: {
PORT: 3000
},
cwd: __dirname
}
}
},
concurrent: {
tasks: ['watch','nodemon'],
options: {
logConcurrentOutput: true
}
}
});
// 加载"uglify"插件..
grunt.loadNpmTasks('grunt-contrib-watch');
grunt.loadNpmTasks('grunt-contrib-coffee');
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-nodemon');
grunt.loadNpmTasks('grunt-concurrent');
//grunt.loadNpmTasks('grunt-ssh');
grunt.option('force', true);
// 注册默认任务.
grunt.registerTask('default', ['concurrent']);
};
