vue 原始碼 斷點除錯

1、新增sourceMap

sourceMap: true

 

2、npm run dev 會生成vue.js.map

3、斷點除錯

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <title>vue原始碼測試</title>
    </head>
    <body>
        <div id="app">
            <
div v-for="item in list"> {{ item }} </div> </div> <script src="./vue.js"></script> <script type="text/javascript"> var app = new Vue({ el: '#app', data: { list: [
1, 2, 3] } }) </script> </body> </html>
