pro-uglifyjs-webpack-plugin

It's essentially a uglifyjs webpack plugin, but extended with extra option.

Overview

You can replace webpack.optimize.UglifyJsPlugin with this plugin. Besides common usage of uglifyjs, the new-added option wrapCatch enables you:

wrap eval:

...
eval( 'var a = 5; console.log( a )' );
...

=>

...
try {
    eval( 'var a = 5; console.log( a )' );
}
catch ( e ) {
    e.message += '<info extracted from the source, such as function name or code snippets>';
    throw e;
}
...

wrap function body:

function a() {
    // function body goes here
}

=> 

function a() {
    try {
        // function body goes here
    }
    catch ( e ) {
        e.message += '<info extracted from the source, such as function name or code snippets>';
        throw e;
    }
}

you should only:

1. set the wrapCatch option to true.
2. add directive "use catch;" where you need the plugin to wrap something for you.

Installation

npm install --save pro-uglifyjs-webpack-plugin

    new proUglify( {
        wrapCatch: true,
        compress: { ... },
        mangle: false,
        output: {
            comments: true
        }
