我需要将样式表的内容插入到 HTML 页面的 <head> 中.我如何在 Gulp 中做到这一点?
I need to insert the content of a stylesheet into the <head> of an HTML page. How can I do it in Gulp?
之前(我所拥有的):
<head>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>
之后(我想要的):
<head>
<style>
p { color: pink; }
</style>
</head>
请注意，我不需要将 CSS 内联到元素中，只需将 CSS 的内容放在 <head> 中即可.
Note that I do not need to inline CSS into the elements, but just put the contents of CSS in the <head>.
你可以轻松使用 gulp-replace，像这样:
You could easily use gulp-replace, like so:
var gulp = require('gulp'),
replace = require('gulp-replace'),
fs = require('fs');
// in your task
return gulp.src(...)
.pipe(replace(/<link href="style.css"[^>]*>/, function(s) {
var style = fs.readFileSync('style.css', 'utf8');
return '<style>
' + style + '
</style>';
}))
.pipe(gulp.dest(...));
您还可以轻松修改替换 RegEx 以处理不同的文件.
You can also easily modify the replacement RegEx to work with different files, too.
return gulp.src(...)
.pipe(replace(/<link href="([^.].css)"[^>]*>/g, function(s, filename) {
var style = fs.readFileSync(filename, 'utf8');
return '<style>
' + style + '
</style>';
}))
.pipe(gulp.dest(...));
