丑化失败。意想不到的字符'`' [英] Uglification failed. Unexpected character '`'
问题描述
gulp-uglify无法隐藏这段代码:
var alertString =`<?xml version = 1.0encoding =UTF-8?>
<文件>
< alertTemplate>
< title> $ {title}< / title>
< description> $ {description}< / description>
< / alertTemplate>
< / document>`
抱怨字符:`。该字符适用于苹果的JS框架。
我看不到uglify包内的任何内容忽略这些字符及其中的文本字符串。我是否缺少某些文档?
Gulp-uglify还没有官方支持ECMAScript 2015(又名ES6,又名Harmony ),但是可以使用开发中的存储库进行一些修改。
操作方法:
- 打开控制台并输入
cd node_modules / gulp-uglify
< ol start =2>
依赖项: {
uglify-js:git + https://github.com/mishoo/UglifyJS2.git#harmony
},
- 控制台输入:
npm update
准备运行 .pipe(uglify ())
再次
替代解决方案
- 通过
npm
下载以下内容:
npm install --save-dev gulp-uglify gulp-babel babel-preset-es2015
- 在
gulpfile.js
中添加以下要求:
var babel = require('gulp-babel'),
uglify = requir E(吞掉-丑化);
- 吞食任务如下:
gulp.task('uglify',function(){
gulp.src('*。js' )
.pipe(uglify()。on('error',function(e))
.pipe(babel({
presets:['es2015']
}))
.pipe {
console.log(e);
}))
.pipe(gulp.dest('js'));
});
这个功能是将所有的EcmaScript 2015 JS代码转储到EcmaScript5中,然后将其清除。
gulp-uglify is unable to uglify this piece of code:
var alertString = `<?xml version="1.0" encoding="UTF-8" ?>
<document>
<alertTemplate>
<title>${title}</title>
<description>${description}</description>
</alertTemplate>
</document>`
it complains at the character: `. The character is valid for the apple's JS framework. I can't see anything inside the uglify package to ignore those characters and the text string inside it. Am i missing something from the documentation?
Gulp-uglify has yet no official support for ECMAScript 2015 (aka ES6, aka Harmony) but with a little modification the on-development repository can be used.
How-to:
- Open Console and enter
cd node_modules/gulp-uglify
- Edit package.json
dependencies": {
"uglify-js": "git+https://github.com/mishoo/UglifyJS2.git#harmony"
},
- Console enter:
npm update
And it is ready to run .pipe(uglify())
again
Alternate Solution
- Download the following via
npm
:
npm install --save-dev gulp-uglify gulp-babel babel-preset-es2015
- Add the following requires in the
gulpfile.js
:
var babel = require('gulp-babel'),
uglify = require('gulp-uglify');
- The gulp task will be as follow:
gulp.task('uglify', function(){
gulp.src('*.js')
.pipe(babel({
presets: ['es2015']
}))
.pipe(uglify().on('error', function(e){
console.log(e);
}))
.pipe(gulp.dest('js'));
});
What this does is transpile all the EcmaScript 2015 JS code to EcmaScript5 and then uglifies it.
