server.js
const express = require("express");
const bodyParser = require("body-parser");
const cors = require("cors");
const app = express();
var corsOptions = {
origin: "http://localhost:8080",
};
app.use(cors(corsOptions));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
// simple route
app.get("/", (req, res) => {
res.json({ message: "it works." });
});
// set port, listen for requests
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}.`);
});

Answer 1

It appears you are attempting to POST to a route that doesn't exist. You will need to build out your /api/auth/signup route in order to send a request to it from axios.
// simple example of post route
app.post("/api/auth/signup", (req, res) => {
const { username, email, password } = req.body;
// Your logic to register user in your database
// Send response after database interaction
res.status(201).json({ message: 'User signed up for service' })
});

For each Specific route you need to implement respective route in your application.
In your application, if you need to have access to two post request of different url, you need to handle two post route.
For`/api/auth/signin`
app.post('/api/auth/signin', (req, res)=>{
//Your Implementation here
res.status(201).json({message: 'Your Message'})
})
For`/api/auth/signup`
app.post('/api/auth/signup', (req, res)=>{
//Your Implementation here
res.status(201).json({message: 'Your Message'})
})
