I am new to NodeJS and can't connect to the server http://localhost:6000/

server.js

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

const app = express();

app.use(express.urlencoded({extended: false}));
app.use(express.json);

app.use(cors());

app.use(express.static('website'));

const port = 6000;
const server = app.listen(port, listening);
function listening(){
    console.log("localhost port: "   port);
}

app.post('/postdata', (request, response) =>{
    console.log("POST request received!");
});

app.get("/getdata", (request, response) =>{

})

app.js

const postData = async ( url = '', data = {})=>{
    // console.log(data);
        const response = await fetch(url, {
        method: 'POST', 
        credentials: 'same-origin',
        headers: {
            'Content-Type': 'application/json',
        },     
        body: JSON.stringify(data), 
    });

    try {
        const newData = await response.json();
        console.log(newData);
        return newData;
    }catch(error) {
        console.log("error", error);
    }
}

postData('/postdata', {Works:456456});

CodePudding user response：

The issue seemed to be with missing brackets:

app.use(express.json());

You are trying to send request to the server without base url. replace it in this way:

const postData = async ( url = '', data = {})=>{
    // console.log(data);
        const response = await fetch(url, {
        method: 'POST', 
        credentials: 'same-origin',
        headers: {
            'Content-Type': 'application/json',
        },     
        body: JSON.stringify(data), 
    });

    try {
        const newData = await response.json();
        console.log(newData);
        return newData;
    }catch(error) {
        console.log("error", error);
    }
}

postData('http://localhost:6000/postdata', {Works:456456});
