shipped-try-catch-webpack-plugin

Why try-catch?

Usually we can debug our code with the help of chrome devtools (for PC site or mobile site simulate), and we can also debug some mobile browsers with Chrome devtools(I mean which using WebKit and open developer debug options). But there are always some werid browsers keeping away us to debug, e.g. huawei Browser. Not just that, some browsers even can not capture errors using window.onerror = function(){}, e.g. huawei browser( I really don't mean to it). So, how can we locate error? Yeah, use try-catch block!

Usage

npm i try-catch-webpack-plugin -D
# or
yarn add try-catch-webpack-plugin -D

In your webpack.config.js:

const TryCatchPlugin = require('try-catch-webpack-plugin');

config = {

    ...
    plugins: [new TryCatchPlugin({
        // default false. define whether wraps prd assets.(prd usually is minified)
        wrapperPrd: true, 

        // default like this. Define wrapper format. 
        // {{code}} indicates the final asset string. Always keep this pattern.
        wrapper: `try{{{code}}}catch(err){alert('err.message: ' +  err.message + '\n' + 'err.stack: ' + err.stack)}`
    })],
    ...
}

Generally, you can just new TryCatchPlugin() without any param. Then in your bundle.js or chunk, you will see:

try{(window["webpackJsonp"] = window["webpackJsonp"] || []).push([[0],{

/***/ "./async.js":
/*!******************!*\
  !*** ./async.js ***!
  \******************/
/*! exports provided: default */
/***/ (function(module, __webpack_exports__, __webpack_require__) {

"use strict";
__webpack_require__.r(__webpack_exports__);
/* harmony default export */ __webpack_exports__["default"] = ({
  name: 1
});

/***/ })

}]);}catch(err){alert('err.message: ' +  err.message + '\n' + 'err.stack: ' + err.stack)}

all your code is wrappered by try-catch(or any format you want).

ChangeLog

• v0.0.3: change default wrapper format to

    try{{{code}}}catch(err){alert('err.message: ' +  err.message + '\n' + 'err.stack: ' + err.stack)}   

• v0.0.2: fix destructure error.
