如何使用Gulp移除HTML文件中的Sourcemap注释

问题:移除Gulp处理后HTML文件中的Sourcemap注释

我将CSS文件副本的扩展名从.css改为.html,并用<style>标签包裹CSS规则,得到page-css.html文件,内容如下:

<style>
html body {
  border: solid 1rem blue;
}
html body .form-row {
  margin-bottom: 15px;
}
/*# sourceMappingURL=data:application/json;charset=utf8;base64,eyJ2ZXJzaW9uIjozLCJzb3VyY2VzIjpbInBhZ2UtY3NzLnNjc3MiXSwibmFtZXMiOltdLCJtYXBwaW5ncyI6IkFBQ0k7RUFDSTs7QUFFQTtFQUNJIiwiZmlsZSI6InBhZ2UtY3NzLmNzcyIsInNvdXJjZXNDb250ZW50IjpbImh0bWwge1xyXG4gICAgYm9keSB7XHJcbiAgICAgICAgYm9yZGVyOiBzb2xpZCAxcmVtIGJsdWU7XHJcblxyXG4gICAgICAgIC5mb3JtLXJvdyB7XHJcbiAgICAgICAgICAgIG1hcmdpbi1ib3R0b206IDE1cHg7XHJcbiAgICAgICAgfVxyXG4gICAgfVxyXG59Il19 */
</style>

我需要移除该文件中的整个Sourcemap注释,但尝试gulp-decomment、gulp-string-replace、gulp-strip-comments等插件,以及以下配置均无效:

const htmlmin = require('gulp-htmlmin');
const decomment = require('gulp-decomment');
const replace = require('gulp-string-replace');
const strip = require('gulp-strip-comments');

...

  //example 1
  .pipe(decomment({trim: true}))
  //example 2
  .pipe(htmlmin({ removeComments: true }))
  //example 3
  .pipe(strip())

完整Gulp代码示例

function genCSS(done) {
  return (
    src(paths.styles.src)
      .pipe(gulpif(!GPREP, sourcemaps.init({})))
      .pipe(sass().on("error", sass.logError))
      .pipe(
        gulpif(
          !GPREP, sourcemaps.write({
            addComment: true,
          })
        )
      )
      //CSS FILE WITH ITS SOURCEMAP IS READY FOR LOCAL DEV PURPOSES
      .pipe(dest(paths.styles.dest))

      //BEGIN THE COPIED/CONVERTED HTML FILE FOR GOOGLE APP PURPOSES
      .pipe(
        rename(function (path) {
          if (path.basename === "page-css") {
            path.extname = ".html";
          }
        })
      )
      .pipe(header("<style>\n"))
      .pipe(footer("</style>\n"))
      //ATTEMPTING TO REMOVE THE SOURCEMAP - BUT IT DOES NOT WORK...
      .pipe(greplace(/\/\*# sourceMappingURL[^\n]+\n/gm,''))
      //STORE THE FILE IN A CLASP LOCATION TO PUSH UP TO GOOGLE
      .pipe(dest(paths.styles.apps))
      .pipe(msync.stream())
  );
  done();
}

可行解决方案

方案1:修正gulp-replace的正则表达式

原正则未匹配到注释结尾的*/,且未考虑注释前后的空白字符。替换为以下正则,确保完整匹配Sourcemap注释块:

.pipe(greplace(/\/\*# sourceMappingURL[\s\S]*?\*\//g, ''))

说明:

  • \/\*# sourceMappingURL:精准匹配Sourcemap注释的开头
  • [\s\S]*?:匹配任意字符(含换行),非贪婪模式避免误匹配其他内容
  • \*\/:匹配注释的结尾

方案2:拆分流,避免HTML分支生成Sourcemap

将本地开发用CSS和Google App用HTML的生成流程拆分,HTML分支不生成Sourcemap注释,从根源避免问题:

function genCSS(done) {
  // 处理本地开发用CSS(带Sourcemap)
  src(paths.styles.src)
    .pipe(gulpif(!GPREP, sourcemaps.init({})))
    .pipe(sass().on("error", sass.logError))
    .pipe(gulpif(!GPREP, sourcemaps.write({ addComment: true })))
    .pipe(dest(paths.styles.dest));

  // 处理Google App用HTML(无Sourcemap)
  src(paths.styles.src)
    .pipe(sass().on("error", sass.logError))
    .pipe(rename(function (path) {
      if (path.basename === "page-css") {
        path.extname = ".html";
      }
    }))
    .pipe(header("<style>\n"))
    .pipe(footer("</style>\n"))
    .pipe(dest(paths.styles.apps))
    .pipe(msync.stream());

  done();
}

这种方式无需后续移除操作,直接生成符合需求的HTML文件。
