Discussion on: Authentication in NodeJS With Express and Mongo - CodeLab #1

View post

I cannot get the test for the signup step to work in postman. I get errors for username, email and password. I have copied exactly what is in the github repo. It is also not adding an entry to the DB.

I was getting the same error. i fixed it by adding

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

under

app.use(bodyParser.json());

index.js ends up looking like this:

const express = require("express");
const bodyParser = require("body-parser");
const user = require("./routes/user");
const InitiateMongoServer = require("./config/db");

// Initiate Mongo Server
InitiateMongoServer();

const app = express();

// PORT
const PORT = process.env.PORT || 4000;

// Middleware
app.use(bodyParser.json());
app.use(express.urlencoded({ extended: true }));
app.use(express.json());

app.get("/", (req, res) => {
  res.json({ message: "API Working" });
});

/**
 * Router Middleware
 * Router - /user/*
 * Method - *
 */
app.use("/user", user);

app.listen(PORT, (req, res) => {
  console.log(`Server Started at PORT ${PORT}`);
});

I have the same issue "cannot get" I think that everything is well configured in postman and I add this lines suggested but still it didn't work... and I'm testing with the original repo I can connect to my db but I can't get anything with submit

Did you add/replace your username password in MongoURI ?

Yes, it is not a DB connection issue. No errors on the console.

Try running the GitHub clone with your Db username password.

How do you now connect it to a frontend login/signup page?

Hi Eugene,

You can simply call the API using axios or fetch to get data.

Here is a sample code snippet on how you can do it.

const config = {
            headers: {
                'Content-Type': "application/json"
            }
 };

const formData = {
input_username,
input_passwrd
};

const response = await axios.post('/user/login', formData, config);
