@babel/plugin-transform-iife-for-debug

Automatically execute debug code in the development environment without affecting production code.

在不会影响到生产代码的前提下，在开发环境对调试代码进行自动执行。

You can easily write debug code in the development environment without having to delete it before testing, avoiding the risk of taking debug code to production.

让你可以在开发环境轻松编写调试代码，而不需要在发布测试环境前仔细核对并删除，能避免把调试代码带上生产的风险。

Install

Using npm:

npm install --save-dev babel-plugin-transform-iife-for-debug

or using yarn:

yarn add babel-plugin-transform-iife-for-debug --dev

Usage

// .babelrc
{
    "plugins": [
        ["transform-iife-for-debug"]
        // with options:
        // ["transform-iife-for-debug", {"targetFlag": "@IIFE-for-debug", ...}]
    ]
}

Source Code:

let normalNum = 1 + 2;

// @IIFE-for-debug
() => {
    normalNum = 10
}

let normalResult = normalNum * 10;

After Transforming(development)

let normalNum = 1 + 2;

// [IIFE]
// @IIFE-for-debug
(() => {
    normalNum = 10
})()

let normalResult = normalNum * 10;

After Transforming(not development)

let normalNum = 1 + 2;

// [removed]
// @IIFE-for-debug

let normalResult = normalNum * 10;

Options

// Default
{   
    targetFlag: '@IIFE-for-debug',
    enableCondition: () => true,
    transformCondition: () => process.env.NODE_ENV==='development'
}
