无法连接Mongodb与我的服务器.js

Question

错误:throw new error_1。MongoParseError(${optionWord} ${Array.from(unsupportedOptions).join(', ')} ${isOrAre} not supported);

我得到这个错误，我的代码是:server . js

const express = require('express');
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}`);
});

我无法连接数据库和我的服务器

Answer 1

我认为你可以简单地连接这段代码-

mongoose.connect(uri, {
useNewURLParser: true,
useUnifiedTopology: true,
})
.then(() => console.log("We are ready with database"))
.catch((err) => console.log(`Database connection error ${err}`));
