我正在使用 Grunt 来优化我的 AngularJS 应用程序以进行生产。它使用 useminPrepare 和 usemin 从我的 index.html 页面读取要合并/缩小的文件。我正在尝试让源映射工作,以便查看发生错误的位置。以下是 package.json 的相关版本:
"grunt": "0.4.5",
"grunt-autoprefixer": "2.2.0",
"grunt-contrib-clean": "~0.5.0",
"grunt-contrib-concat": "~0.3.0",
"grunt-contrib-copy": "~0.5.0",
"grunt-contrib-cssmin": "~0.11.0",
"grunt-contrib-uglify": "~0.9.1",
"grunt-rev": "~0.1.0",
"grunt-usemin": "~2.0.2",
这是我的精简版,Gruntfile.js
仅用于相关任务:
'use strict';
// usemin custom step
var useminAutoprefixer = {
name: 'autoprefixer',
createConfig: require('grunt-usemin/lib/config/cssmin').createConfig // Reuse cssmins createConfig
};
module.exports = function (grunt) {
require('load-grunt-tasks')(grunt);
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
clean: ["dist", '.tmp'],
copy: {
main: {
files: [
{
expand: true,
src: ['**', '!css/**', '!*.js', '!node_modules/**', '!*.log', '!tests/**'],
dest: 'dist/'
}
]
}
},
cssmin: {
options: {
root: './' // Replace relative paths for static resources with absolute path
}
},
rev: {
files: {
src: ['dist/assets/**/*.{js,css}']
}
},
useminPrepare: {
html: 'index.html',
options: {
flow: {
html: {
steps: {
js: ['concat', 'uglifyjs'],
css: ['cssmin', useminAutoprefixer] // Let cssmin concat files so it corrects relative paths to fonts and images
},
post: {
js: [{
name: 'concat',
createConfig: function (context, block) {
context.options.generated.options = {
sourceMap: true
};
}
}, {
name: 'uglifyjs',
createConfig: function (context, block) {
context.options.generated.options = {
sourceMapIn: '.tmp/concat/' + block.dest.replace('.js', '.js.map'),
mangle: false,
beautify: {
beautify: true
}
};
}
}]
}
}
}
}
},
usemin: {
html: ['dist/index.html']
},
uglify: {
options: {
report: 'min',
mangle: false
},
generated: {
options: {
sourceMap: true
}
}
}
});
grunt.registerTask('build', [
'clean', 'useminPrepare', 'concat', 'copy', 'cssmin', 'autoprefixer', 'uglify', 'rev', 'usemin'
]);
};
这些*.js.map
文件正在生成dist/assets/js
。revved JS 文件似乎很好地引用了它们:
//# sourceMappingURL=app.js.map
但是,查看源映射,它似乎有一个错误的目录路径和文件名:
{"version":3,"file":"app.js","sources":["../../../.tmp/concat/assets/js/app.js"] ...
知道如何使源映射与 Grunt、usemin、uglify 和 rev 一起使用吗?
