有没有办法将所有bower安装的库自动组合并缩小为1个文件?
首先,我尝试了最基本的方法:合并所有子目录中的所有.js
个文件:
uglify: {
options: {compress: true},
my_target: { files: {
'vendor.js': ['bower_components/**/*.js'],
} } }
但这显然是一种糟糕的做法。由于错误太多,它也不起作用。
我手动删除了所有文件,并且只保留了每个库所拥有的1个(主)文件,并且它有效。
有没有办法自动完成这项工作?
另外,建议这样做吗? (即将所有供应商库合并为1个文件)

我推荐2个不错的grunt库,Wiredep和Usemin:
的组合Wiredep:自动加载html中bower.json中识别的bower的所有依赖关系
Usemin:检测两个注释标记内的所有src,并且所有源都在dist文件夹中缩小和连接,下面是使用此包的grunt文件的一个小例子,是基于angular to yeoman的生成器这只是一个那个咕噜的简要说明

wiredep: {
options: {
cwd: 'appFolder'
},
app: {
src: ['htmlCollections'],
ignorePath: /\.\.\//
}
},
useminPrepare: {
html: 'htmlCollections',
options: {
dest: 'distributionFolder',
flow: {
html: {
steps: {
js: ['concat', 'uglifyjs'],
css: ['cssmin']
},
post: {}
}
}
}
},
usemin: {
html: ['distributionFolder+HtmlFiles'],
css: ['distributionFolder+cssFiles'],
js: ['distributionFolder+javascriptFiles']
}

只需要wiredep
uglify: {
options: { compress: true },
my_target: {
files: { 'public/vendor.js': require('wiredep')().js
} } },
cssmin: {
minify: {
files: { 'public/vendor.css': require('wiredep')().css
} } },
