babel-plugin-parcel-function

一个使用if-else包裹增强函数的babel插件

不影响原函数的使用，可以在if中注入一些黑科技方法

A babel plugin that uses the if-else package enhancement function

Install

Usage

{
  "plugins": 
     [
          ["babel-plugin-parcel-function",
            {
              prefixName: "global.hotUpdate",
              addFileName: false
            }
          ]
        ]
}

Examples

async function f(arg) {
    await aaa();
    await bbb();
    console.log('eee');
    return 'ddd';
  }

转换后

async function f(arg) {
    if (global.hotUpdate.f) {
        global.hotUpdate.f.call(this,arg);
    } else {
        await aaa();
        await bbb();
        console.log('eee');
        return 'ddd';
    }
}

Options

| name | description | type | default | | ----------- | ------------------------ | ------------ | ------------------ | | prefixName | if判断和if块中的前缀 | String or Array | "global.hotUpdate" | | addFileName | 是否将文件名添加到前缀中 | Boolean | false |

when Options

{
       prefixName: "aaa.bbb.ccc",
       addFileName: false
}

code

function f(aa,bb) {
    let asd = 1 
    asd = aa + bb
    console.log("aaa")
  }

after transform

function f(aa, bb) {
    if (aaa.bbb.ccc.f) {
        aaa.bbb.ccc.f.call(this, aa, bb);
    } else {
        let asd = 1;
        asd = aa + bb;
        console.log("aaa");
    }
}

if中的判断和if块中的代码由 [prefixName + fileName + 函数名] 决定
