app.use("/posts", postRoutes);

//Compuslory dependenci
app.use(bodyParser.json({limit:"30mb", extended:"true"}));
app.use(bodyParser.urlencoded({limit:"30mb", extended:"true"}));
app.use(cors());

const CONNECTION_URL = "mongodb+srv://username:[e-mail]/<dbname>?retryWrites=true&w=majority";
const PORT = process.env.PORT || 9000;

mongoose.connect(CONNECTION_URL, {useNewUrlParser: true, useUnifiedTopology:true})
.then(() => app.listen(PORT, () => console.log(`server runing on ${PORT}`)))
.catch((err) => console.log(err))

mongoose.set('useFindAndModify', false)  
import express from "express";
const router = express.Router();
router.get('/', (req, res) => {
res.send('this dont  work')
}) 
export default router;

它给了我错误，因为javaScript读取代码行，我的错误是在cors之上创建路由或表达它应该在

const app = express();


//Compuslory dependenci
app.use(bodyParser.json({limit:"30mb", extended:"true"}));
app.use(bodyParser.urlencoded({limit:"30mb", extended:"true"}));
app.use(cors());
const CONNECTION_URL = 
"mongodb+srv://username:[e-mail]/<dbname>? 
retryWrites=true&w=majority";
const PORT = process.env.PORT || 9000;
mongoose.connect(CONNECTION_URL, {useNewUrlParser: true, useUnifiedTopology:true})
.then(() => app.listen(PORT, () => console.log(`server runing on ${PORT}`)))
.catch((err) => console.log(err))
app.use("/posts", postRoutes);
mongoose.set('useFindAndModify', false)
