如何使用Chrome扩展名执行SQL数据库？

Question

我有一个React应用程序，其连接的SQL数据库在本地主机上运行，这很好。现在，我将React应用程序移至Chrome扩展程序中，该应用程序也可以与我的数据库一起使用。 我的问题是，每次我打开Chrome UP应用程序时，我都需要在SQL Server的控制台中运行

npm run devStart

，以便该应用程序可以发送和获取数据。

是在使用Chrome应用时自动启动SQL Server的一种方法？

manifest.json

{
"manifest_version": 2,
"name": "Study Buddy",
"author": "dave",
"version":"1.0.1",
"description": "All in one app for all your studying needs!",
"icons":{
  "16": "favicon.ico",
  "48": "favicon.ico",
  "128": "favicon.ico"
},
"browser_action":{
  "default_popup":"index.html",
  "default_title": "Study Buddy"
},
"background": {
  "scripts": ["newbackground.js"],
  "persistent": false
}
}

sqlserver.js

const express = require('express'); 
const app = express()

const cors = require('cors') 

const db = mysql.createConnection({
    host:'localhost',
    user: 'root',
    password: '******',
    database: 'calendardb',

var currentDate = ""

app.use(cors());
app.use(express.json()); 

// insert information in to DB
app.post('/send',(req,res) =>{
    const userEvent = req.body.userEvent
    const userDate = req.body.userDate
    currentDate = req.body.userDate
    console.log("FROM DB ADD",userDate,"d",currentDate)
    db.query('INSERT INTO calevent (userEvent, userDate) VALUES (?,?)', 
    [userEvent,userDate], (err,result) =>{
        if(err){
            console.log(err)
        } else{
            res.send("Data send to DB")
        }
    }
    );
  });

//Getting Specific  data from DB
app.get("/getData",(req, res) =>{
    const userDate = req.query.userDate
    console.log(userDate)
    //console.log(req.params.event)
    db.query("SELECT * FROM calevent WHERE userDate = ?", userDate, (err, result) => {
        if(err){

            res.send(result)
        }
        console.log(result)
    });
});

//Update data
app.put('/update', (req,res) => {
    const newUserEvent = req.body.userEvent;
    const id = req.body.id;
    db.query("UPDATE calevent SET userEvent = ? WHERE id = ?", [newUserEvent, id],(err, result) => {
        if(err){
            console.log(err)
        }else{
            res.send(result)
        }

        } else{
            res.send(result)
        }
    }
        )
})

app.listen(3001, () =>{
    console.log('bonger');
});

package.json

}

我们可以使用pm2库来设置您的server.js自动运行。

NPM安装PM2pm2start server.js - 名称 - -watch && pm2 Save && pm2startup
