我正在敲打这个;
我想根据开发环境或生产来改变我的html文件。我在Stackoverflow上关注了一个主题,但不知何故preprocess-context参数始终是文件中的最后一个。好的,我会加入一些片段。
一块Grunt.js
//Grunt task to automate environment configuration for future tasks.
env : {
//USER : 'raymond',
//PATH : '/bin:/usr/bin',
options : {
/* Shared Options Hash */
//globalOption : 'foo'
},
dev: {
NODE_ENV : 'DEVELOPMENT'
},
prod : {
NODE_ENV : 'PRODUCTION'
}
},
//Grunt task around preprocess npm module.
preprocess : {
options: {
context : {
DEBUG : true,
now : '<%= grunt.template.today() %>',//@TODO .toISOString()
ver : '<%= pkg.version %>'
}
},
dev : {
options : {
context : {
url : 'http://www.<%= pkg.name %><%= pkg.tld.dev %>',
concat : '<%= pkg.name %><%= pkg.tld.dev %>.concat.js',
uglify : '<%= pkg.name %><%= pkg.tld.dev %>.concat.min.js',
css : '<%= pkg.name %><%= pkg.tld.dev %>.css',
cssMin : '<%= pkg.name %><%= pkg.tld.dev %>.min.css'
}
},
src : 'index.html',
dest : 'dist/dev/index.html'
// @TODO write to dist/dev-directory fails cause probably permissions checked it;
// I have to 777 on www-data to run Nginx properly. Strange cause raymond is part of group www-data
},
prod : {
options : {
context : {
url : 'http://www.<%= pkg.name %><%= pkg.tld.prod %>',
concat : '<%= pkg.name %><%= pkg.tld.prod %>.concat.js',
uglify : '<%= pkg.name %><%= pkg.tld.prod %>.concat.min.js',
css : '<%= pkg.name %><%= pkg.tld.prod %>.css',
cssMin : '<%= pkg.name %><%= pkg.tld.prod %>.min.css'
}
},
src : '<%= preprocess.dev.src %>',
dest : 'dist/prod/index.html'
}
},

这是index.html的输出,由preprocess渲染:dev;
<!-- <script src="http://www.myradon.net/js/myradon.net.concat.js"></script> -->
<script src="http://www.myradon.net/js/myradon.net.concat.min.js"></script>

_gaq.push(['_trackPageview']);
(function () {

ga.type = 'text/javascript';

正如你所看到的那样@if NODE_ENV =='DEVELOPMENT'被忽略但是preprocess:dev的上下文参数被传递给@if NODE_ENV =='PRODUCTION'这对我来说真的没有任何意义。你有线索吗?!

好吧,伙计们我正在使用Grunt-processhtml。它完全符合我的想法。您可以在上下文中设置变量。删除html块,基于envirenment设置url或metatags innerHTML非常好。唯一的缺点是,可能有一个设置,它留下html-comment-markup来处理html代码。

我不知道这是否重要,但我使用单一&#39; =&#39;就像每个例子一样: grunt-preprocess on npm
<!-- @if NODE_ENV='production' -->
<script src="some/production/lib/like/analytics.js"></script>
<!-- @endif -->
