Question

gulp压缩打包后，发现好像并没有减少http请求

task代码

gulp.task('minifyjs', function() {
    return gulp.src('public/js/views/*.js')
        .pipe($.requirejsOptimize({
            baseUrl: "./public/js",
            insertRequire: ['app'],
            mainConfigFile: "./public/js/require-config.js",
            preserveLicenseComments: false,
            useStrict: true,
            include: ["./lib/requirejs/require.js"]
        }))
        .pipe(concat('main.js'))
        .pipe(rename({ suffix: '.min' }))
        .pipe(uglify())
        .pipe(gulp.dest('public/js/dist'));
});

页面上代码

<script src="js/lib/requirejs/require.js" data-main="js/dist/main.min"></script>

但发现http请求数量还是很多个，用gulp-concat进行了合并，但仍然提示会去请求合并中的每一个问题件，为什么？

Answer 1

用r.js之类的做优化。
主要配置没问题的话应该是能减少http请求的。贴个亲测有效的代码。
仔细看，上面代码明显有问题。

gulp.task('minifyjs', function() {
    return gulp.src('public/js/views/app.js')
        .pipe($.requirejsOptimize({
            baseUrl: "./public/js/views",
            insertRequire: ['app'],
            mainConfigFile: "./public/js/views/require-config.js",
            preserveLicenseComments: false,
            useStrict: true,
            include: ["../lib/requirejs/require.js"]
        }))
        .pipe(gulp.dest('public/dist/js'));
});

Answer 2

应该是你的代码里面有很多的require，每一个都会被requirejs包装成一个请求，但是除了第一个以外，剩下的都是直接读缓存了
可以尝试减少代码中require的次数来减少这个

Answer 3

页面加载那里应该修改成加载打包后的JS啊。。不然IO次数当然没区别。
