标签: gulp-uglify

正在压缩的js文件以相同的文件名输出.

gulp.task('compressjs', function () {
  gulp.src('app/**/*.js')
    .pipe(uglify())
    .pipe(gulp.dest('dist'));
});

我如何让它min.js在后面输出文件？

我是gulp的新手,我按照http://leveluptuts.com/tutorials/learning-gulp中的教程,我收到此错误:

events.js:141
  throw er; // Unhandled 'error' event

at maybe_assign (/home/kid/node_modules/gulp-uglify/node_modules/uglify-js/lib/parse.js:1427:20)

这是我的代码:

 var gulp = require('gulp')
    uglify = require('gulp-uglify');

gulp.task('default', function() {
    // body...
    gulp.src('js/*.js')
    .pipe(uglify())
    .pipe(gulp.dest('minjs'));

});

和目录树,只是简单

-gulp
     -js/
     -gulpfile.js

非常感谢

我试图使用gulp来缩小包含JS文件的文件夹.但是,其中一个文件存在上述错误,导致其无法缩小.

我设法抓住并打印了错误,我在这里部分打印过:

JS_Parse_Error {
 message: 'SyntaxError: Unexpected token: punc ())',
 filename: 'ex.js',
 line: 189,
 col: 25,
 pos: 6482,
 stack: Error\n    at new JS_Parse_Error (eval at <anonymous> ... ) 
 plugin: 'gulp-uglify',
 fileName: '.../js/ex.js',
 showStack: false
}

有问题的文件包含以下内容,缩写为:

function() {
  ...
  $.confirm({
    buttons: {
        confirm: function() {
            $.post('/ajax-handler', {
                    ...
                })
                .done( function(response) {
                    var data = filterResponse(response);
                    if (data['status'] == 'success') {
                        sleep(1000).then(() => {
                    *       ...
                        });
                        sleep(5000).then(() => {
                            ...  
                        });

                    } else {
                        console.log('Oops!');
                    }
                })
                .fail( function(err, …

我正在尝试缩小我的脚本文件,我正在使用gulp任务运行器而我正在尝试gulp-uglify插件

码:

 gulp.task('concat', function() {
    return gulp.src('app/**/*.js')
        // .pipe(concat('script.js'))
        .pipe(uglify())
        .pipe(gulp.dest('./dist/'))
});

但我得到的错误是

当我尝试运行gulp任务作为gulp concat任何帮助将不胜感激

当我运行gulp时,我收到以下错误:

[12:54:14] { [GulpUglifyError: unable to minify JavaScript]
cause:
{ [SyntaxError: Unexpected token: operator (>)]
 message: 'Unexpected token: operator (>)',
 filename: 'bundle.js',
 line: 3284,
 col: 46,
 pos: 126739 },
plugin: 'gulp-uglify',
fileName: 'C:\\servers\\vagrant\\workspace\\awesome\\web\\tool\\bundle.js',
showStack: false }

违规行包含箭头功能:

var zeroCount = numberArray.filter(v => v === 0).length

我知道我可以用以下内容替换它来弥补缩小错误:

var zeroCount = numberArray.filter(function(v) {return v === 0;}).length

如何在包含ES6功能的代码上运行gulp而不会导致缩小失败？

我正在尝试使用压缩我的项目gulp-uglify,但是Unexpected token: punc ()每当遇到代码中的箭头函数时,gulp似乎都会抛出错误.有什么办法可以解决这个问题吗？谢谢.

大口喝,崩溃test.js

// Function with callback to simulate the real code
function test(callback) {
    if (typeof callback === "function") callback();
}

// Causes a crash
test(() => {
    console.log("Test ran successfully!");
});

// Doesn't cause a crash
test(function () {
    console.log("Test ran successfully!");
});

gulpfile.js

var gulp = require("gulp");
var concat = require("gulp-concat");
var uglify = require("gulp-uglify");

gulp.task("scripts", function() {
    gulp.src([
        "./gulp-crash-test.js"
    ]).pipe(
        concat("gulp-crash-test.min.js")
    ).pipe(
        uglify().on('error', function(e){
            console.log(e);
        })
    ).pipe(
        gulp.dest("./")
    );
}); …

当我使用gulp-uglify与browserify时,我得到一个错误

这是我的脚本任务

gulp.task('scripts', function() {

    var bundler = browserify({
        entries: ['./src/scripts/main.js'],
        debug: debug
    }).transform(stringify()); // the error persist even without this transformation

    bundler
        .bundle()
        .on('error', handleErrors)
        .pipe(source(getBundleName() + '.js'))
        .pipe(jshint()) …

我收到了这个错误.昨天运行gulp工作得很好,但今天早上(改变了NO代码),我收到了这个错误.

我只是想检查是否有办法来修改变量,除了Gulp-Uglify的特定变量.如果没有,是否有解决方案来达到我想要的效果？谢谢.

我有以下任务:

var uglify = require('gulp-uglify');

gulp.task('scripts', function () {
  gulp.src('./src/scripts/*.js')
    .pipe(concat('main.js'))
    .pipe(uglify())
    .pipe(gulp.dest('./dist'));
});

以下2个javascript文件,test1.js:

var testOneOutput = 'function one';
console.log(testOneOutput);

和test2.js

var testTwoOutput = 'function two';
console.log(testTwoOutput);

并且所有目录都已正确设置.虽然当我执行任务时,我没有迹象表明是否有丑陋的工作.连接工作很好.我错过了什么吗？
