JavaScriptライブラリを醜くするためにこれを行う方法は次のとおりです。

var babelify = require("babelify");
var browserify = require('browserify');
var reactify = require('reactify');
var source = require('vinyl-source-stream');
var buffer = require('vinyl-buffer');
var uglify = require('gulp-uglify');

browserify(componentPath + "app.jsx")
    .transform(reactify)
    .transform(babelify)
    .bundle()
    .pipe(source('app.js'))
    .pipe(buffer())
    .pipe(uglify())
    .pipe(gulp.dest(buildPath));

最近すべてのライブラリを最新のものに更新するまで、これは機能していました（つまり、それがgulp-uglify問題なのか、reactifyそれともbabelify.

あなたはすでに非常に良いスタートを切っています。デバッグ ログによると、元のコードのコメントが削除されていなかったようです。/path/to/my/application/app.jsそこにあるものを確認するには、41 行目でチェックアウトする必要があります。

コメントがある場合は、コメント削除プラグインを確認することをお勧めします。私の場合、最新gulp-strip-commentsのものは根本的な原因です。古いバージョンに戻しましたが、すべて正常に動作します。
