gulp:自动添加版本号以请求防止浏览器缓存 [英] gulp: Automatically add version number to request for preventing browser cache
问题描述
我通过在服务器上直接构建源代码文件来部署我的项目。为了防止缓存问题,最佳做法可能是添加一个唯一编号来请求url,请参阅:在Web应用程序升级时防止浏览器缓存;
在npm版本库中,我无法找到自动添加版本号的请求的工具。我在问是否有人发明过此类工具。
可能的实现可能如下:
我在 src /
文件夹,使用以下脚本标记
< script src =js / app。 js<! - %nocache% - >>< / script>
在构建过程中,它被复制到 dist /
文件夹和评论被替换为自动增量编号
< script src =js / app.js?t = 1234> ;< /脚本>
您可以使用 gulp-version-number
。它可以通过向URL添加参数来为HTML文档中的链接脚本,样式表和其他文件添加版本号。例如:
$ b
< link rel =stylesheethref =main.css> ;
变成:
< link rel =stylesheethref =main.css?v = 474dee2efac59e2dcac7bf6c37365ed0>
您甚至不必指定占位符,就像您在示例实现中显示的那样。
示例用法:
const $ = gulpLoadPlugins();
const'version':{$ b $'''','$ b''','$ b $''' :['css','js'],
},
};
$ b gulp.task('html',()=> {
return gulp.src('src / ** / *。html')
.pipe($ .htmlmin({collapseWhitespace:true}))
.pipe($。versionNumber(versionConfig))
.pipe(gulp.dest('docroot'));
});
I deploy my project by building source files with gulp right on the server. To prevent caching issues, the best practice could be adding a unique number to request url, see: Preventing browser caching on web application upgrades;
In npm repositories, I couldn't find a tool for automatically adding version number to request. I'm asking if someone has invented such tool before.
Possible implementation could be the following:
I have a file index.html in src/
folder, with following script tag
<script src="js/app.js<!-- %nocache% -->"></script>
During build it is copied to dist/
folder, and comment is replaced by autoincrement number
<script src="js/app.js?t=1234"></script>
You can use gulp-version-number
for this. It can add version numbers to linked scripts, stylesheets, and other files in you HTML documents, by appending an argument to the URLs. For example:
<link rel="stylesheet" href="main.css">
becomes:
<link rel="stylesheet" href="main.css?v=474dee2efac59e2dcac7bf6c37365ed0">
You don't even have to specify a placeholder, like you showed in your example implementation. And it's configurable.
Example usage:
const $ = gulpLoadPlugins();
const versionConfig = {
'value': '%MDS%',
'append': {
'key': 'v',
'to': ['css', 'js'],
},
};
gulp.task('html', () => {
return gulp.src('src/**/*.html')
.pipe($.htmlmin({collapseWhitespace: true}))
.pipe($.versionNumber(versionConfig))
.pipe(gulp.dest('docroot'));
});
