我试图使用gulp-usemin
来捆绑我的CSS
和javascript
文件用于生产。gulp-usemin
在我的CSS
文件上工作得很好,但没有输出任何与我的javascript
文件相关的东西。有人能指出我哪里做错了吗?
我遇到了一个类似于使用gulp-usemin在html文件中重写丑化文件的问题,但提出的解决方案不起作用。
作为参考,我的node
版本号是v0.12.1
,我的gulp
版本号如下:
"devDependencies": {
"gulp": "^3.9.1",
"gulp-minify-css": "^1.2.4",
"gulp-rev": "^7.1.2",
"gulp-uglify": "^2.0.0",
"gulp-usemin": "^0.3.24"
}
index.html
<html>
<head>
<meta charset="utf-8">
<!-- build:css css/site.css -->
<link rel="stylesheet" href="stylesheets/style.css" type="text/css" media="all" />
<link rel="stylesheet" href="bower_components/font-awesome/css/font-awesome.min.css" type="text/css" media="all" />
<!-- endbuild -->
<!-- build:js js/site.js -->
<script type="text/javascript" src='bower_components/gsap/src/minified/TweenMax.min.js'> </script>
<script type="text/javascript" src='bower_components/d3/d3.js'> </script>
<script type="text/javascript" src='bower_components/d3-tip/index.js'> </script>
<script type="text/javascript" src='bower_components/moment/moment.js'> </script>
<script type="text/javascript" src='chart.js'> </script>
<!-- endbuild -->
</head>
<body>
</body>
</html>
gulp file
var gulp = require('gulp');
var uglify = require('gulp-uglify');
var usemin = require('gulp-usemin');
var minifyCss = require('gulp-minify-css');
gulp.task('build', function() {
return gulp.src(['index.html'])
.pipe(usemin({
css: [minifyCss()],
js: [uglify()]
}))
.pipe(gulp.dest('dist/'));
});
运行gulp build
后生成dist
目录,如下所示
dist/
css/
site.css
index.html
我生成的index。html是
<html>
<head>
<meta charset="utf-8">
<link rel="stylesheet" href="css/site.css" media="all"/>
</head>
<body>
</body>
</html>
有什么明显的我错过了吗?为什么css
块工作,而js
块静默失败?
gulp-usemin
使用的正则表达式不允许在开始的<script>
和结束的</script>
标记之间有任何空白。它也不允许type="text/javascript"
属性。
有关匹配和非匹配的示例,请参阅regex101页。
所以这个:
<!-- build:js js/site.js -->
<script type="text/javascript" src='bower_components/gsap/src/minified/TweenMax.min.js'> </script>
<script type="text/javascript" src='bower_components/d3/d3.js'> </script>
<script type="text/javascript" src='bower_components/d3-tip/index.js'> </script>
<script type="text/javascript" src='bower_components/moment/moment.js'> </script>
<script type="text/javascript" src='chart.js'> </script>
<!-- endbuild -->
应该是这样的:
<!-- build:js js/site.js -->
<script src='bower_components/gsap/src/minified/TweenMax.min.js'></script>
<script src='bower_components/d3/d3.js'></script>
<script src='bower_components/d3-tip/index.js'></script>
<script src='bower_components/moment/moment.js'></script>
<script src='chart.js'></script>
<!-- endbuild -->
