I am a beginner to react and node and this will be a very basic problem. I am creating a basic react fronted with a node backend. I setup mysql database connection and all set. I want to insert user details using /createUser api call to store data to database. I run the server/app.js, react serve and index.js which contained my listener for /createUser. When I input username,password using my form, empty req.body object will be returned in express.post method while I am expecting the username and password I entered. In other case, when I start the listener, react front is not loading by giving the error below.
GET http://localhost:3000/%PUBLIC_URL%/manifest.json 404 (Not Found) manifest.json:1 Manifest: Line: 1, column: 1, Unexpected token.
It seems like node component cannot access my manifest file. Am I correct?
index.js
const express = require('express');
const bodyParser = require('body-parser');
const store = require('./store');
const app = express();
app.use(express.static('public'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json({ type: 'application/*+json' }));
app.use(bodyParser.json());
app.post('/createUser', (req, res) => {
console.log(req.body);
store
.createUser({
username: req.body.username,
password: req.body.password
})
.then(() => res.sendStatus(200))
})
app.listen(3001, () => {
console.log('Server running on http://localhost:3001')
})
login.js
import React, { Component } from 'react';
import classes from './Login.css';
function post (path, data) {
console.log(data);
return window.fetch(path, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(data)
})
}
function handleLoginClick(e) {
e.preventDefault();
console.log('The link was clicked.');
const Login = document.querySelector('.Login');
const username = Login.querySelector('.username').value;
const password = Login.querySelector('.password').value;
post('/login', { username, password })
.then(({ status }) => {
if (status === 200) alert('login success')
else alert('login failed')
})
}
function handleSignupClick(e) {
e.preventDefault();
console.log('The link was clicked sign up.');
const CreateUser = document.querySelector('.CreateUser')
const username = CreateUser.querySelector('.username').value;
const password = CreateUser.querySelector('.password').value;
post('/createUser', { username, password })
}
class Login extends Component {
componentDidMount() {
}
componentWillUnmount() {
}
render() {
return (
<div>
<form className="Login">
<h1>Login</h1>
<input type="text" className="username" placeholder="username"/>
<input type="password" className="password" placeholder="password"/>
<input type="submit" value="Login" onClick={handleLoginClick}/>
</form>
<form className="CreateUser">
<h1>Create account</h1>
<input type="text" className="username" placeholder="username"/>
<input type="password" className="password" placeholder="password"/>
<input type="submit" value="Create" onClick={handleSignupClick}/>
</form>
</div>
);
}
}
export default Login;
What's wrong with my code? Can someone please explain me.

Try to replace bodyParser configuration to following lines of code:
app.use(bodyParser.json({ limit: '100mb' }));
app.use(bodyParser.urlencoded({ limit: '100mb', extended: false }));
This might help you

There are two solutions here:
http://localhost:3001/manifest.json
to match how you have express.static
setup. express.static
to app.use('/public', express.static('public'));
such that http://localhost:3001/public/manifest.json
will refer to the given file.
