Node.js v18.7.0 [nodemon] 應用程式崩潰 - 在開始之前等待檔案更改...
代碼是
const cors = require('cors');
const mongoose = require('mongoose');
require('dotenv').config();
const app = express ();
const port = process.env.PORT || 5000;
app.use(cors());
app.use(express.json());
const uri = process.env.ATLAS_URI;
mongoose.connect(uri, {useNewUrlParser: true, useCreateIndex: true}
);
const connection = mongoose.connection;
connection.once('open', ()=>{
console.log("MongoDB database connection established successfully");
})
app.listen(port, () => {
console.log('Server is running on port: ${port}')
});
process.on('warning', e => console.warn(e.stack));```

根據貓鼬檔案
useCreateIndex不是一個選擇mongooose.connect()
