调试nodejs代码还是比较基础的技能，开篇博客记录一下

记录vscode调试nodejs

我们在demo文件夹下创建index.js，内容如下

const http = require('http');
const url = require('url');

const server = http.createServer((req, res) => {
    const query = url.parse(req.url, true).query;
    const a = query.a;
    const b = query.b;
    const sum = parseInt(a, 10) + parseInt(b, 10);
    console.log(`${a} + ${b} = ${sum}`);
});

server.listen(3000, () => {
    console.log('Server running at http://localhost:3000/');
});
