gulp-remanifest

一个实现文件名hash值替换的gulp插件.

此插件基于 gulp-rev-replace.

Install

npm i gulp-remanifest -D

使用

添加以下代码到 gulpfile.js:

简单的字符串替换

const remanifest = require('gulp-remanifest');
const manifestJson = require('manifest.json');

gulp.task('remanifest', function(){
  gulp.src(['*.html'])
    .pipe(remanifest({ manifest: manifestJson }))
    .pipe(gulp.dest('output/'));
});

添加替换前缀字符串和自定义匹配逻辑

const remanifest = require('gulp-remanifest');
const manifestJson = require('manifest.json');

gulp.task('remanifest', function(){
  gulp.src(['*.html'])
    .pipe(remanifest({ 
      manifest: manifestJson,
      prefix: 'build/',
      matched: function(source, unreved, reved) {
            const ext = path.extname(unreved);
            const _unreved = unreved.replace(new RegExp(ext + '$'), '');
            return source.replace(new RegExp(_unreved + '(.([A-Za-z0-9.]{5,}))?' + ext + '(\s{0,})?(["|\'])', 'gim'), reved + '$3$4');
          }
    }))
    .pipe(gulp.dest('output/'));
});

源文件

<link rel="icon" type="image/x-icon" href="assets/icon.png"/>
<link href="index.css" rel="stylesheet">
<script src="src/index.js"></script>
<script>
  require('src/index.js');
</script>

manifest.json

{
  "index.js": "index.b0ce1e8.js",
  "index.css": "index.4f36a77.css",
  "assets/icon.png": "assets/icon.4336db5.png"
}

替换后输出

<link rel="icon" type="image/x-icon" href="assets/icon.4336db5.png"/>
<link href="index.4f36a77.css" rel="stylesheet">
<script src="index.b0ce1e8.js"></script>
<script>
  require('index.b0ce1e8.js');
</script>

如果manifest.json的值更新了，可以无缝替换.

{
  "index.js": "index.b0ce1e8e4d1ff123.js",
  "index.css": "index.4f36a77fg1f37dg8.css",
  "assets/icon.png": "assets/icon.4336db5fs51w34.png"
}

<link rel="icon" type="image/x-icon" href="assets/icon.4336db5fs51w34.png"/>
<link href="index.4f36a77fg1f37dg8.css" rel="stylesheet">
<script src="index.b0ce1e8e4d1ff123.js"></script>
<script>
  require('index.b0ce1e8e4d1ff123.js');
</script>
