Cannot reach localhost-CodePudding

I'm trying to build a demo application and having "Cannot GET /" error when I try to reach out http://localhost:8800/

On the other hand, the output as expected:

Connected to backend.

mongoDB connected!

Connected to mongoDB.

So I couldn't understand where exactly I have the problem, do you have any suggestions?

    import mongoose from "mongoose";
    import express from "express";
    import authRoute from "./routes/auth.js";
    import usersRoute from "./routes/users.js";
    import hotelsRoute from "./routes/hotels.js";
    import roomsRoute from "./routes/rooms.js";
    
    const app = express();
    // dotenv.config()
    
    const connect = async ()=>{
        try {
            await mongoose.connect('mongodb srv://********@******.mongodb.net/?retryWrites=true&w=majority');
            // Check how we can use .env file 
            console.log("Connected to mongoDB.")
        }   catch (error) {
            throw error 
        }  
    };


mongoose.connection.on("disconnected", ()=>{
    console.log("mongoDB disconnected!")
})
mongoose.connection.on("connected", ()=>{
    console.log("mongoDB connected!")
})

app.use(express.json())

app.use("api/auth", authRoute);
app.use("api/users", usersRoute);
app.use("api/hotels", hotelsRoute);
app.use("api/rooms", roomsRoute);

app.listen(8800, ()=>{
    connect()
    console.log("Connected to backend.")
});

CodePudding user response：

You don't need a root route. However, if you still want something to display, you can just add in your code :

app.get('/', (_, res) => res.send({message: 'Hello from Express'}))

CodePudding user response：

Your code is running, it just doesn't have a route at '/', which is your path when you go to any website. if you want to render something on the page, just add

app.get('/', (req, res)=>{
  res.send('this text will now appear at localhost:8800');
  /*
  you could also import path and do
  path.join(__dirname 'yourfilename.html') to render an html file
  */
})

CodePudding user response：

you can make '/' root

app.get('/', (req, res) => {
  res.send('Hello World!')
})
