Looking for a backend dev that can simply help me implement MONGODB with nextJS and the current model I have now. I have bought https://www.devias.io admin dashboard, and just want to implement auth and database reading with it.
Just want the basic auth setup. It's already setup in the FILES just wanting to know how to configure it properly based on the devias guides
Has anyone done this before I can't find any documentation on it
It's setup with mock data at the moment
SRC/API/AUTH/index.js
import { createResourceId } from '../../utils/create-resource-id';
import { decode, JWT_EXPIRES_IN, JWT_SECRET, sign } from '../../utils/jwt';
import { wait } from '../../utils/wait';
import { users } from './data';
class AuthApi {
async signIn(request) {
const { email, password } = request;
await wait(500);
return new Promise((resolve, reject) => {
try {
// Find the user
const user = users.find((user) => user.email === email);
if (!user || (user.password !== password)) {
reject(new Error('Please check your email and password'));
return;
}
// Create the access token
const accessToken = sign({ userId: user.id }, JWT_SECRET, { expiresIn: JWT_EXPIRES_IN });
resolve({ accessToken });
} catch (err) {
console.error('[Auth Api]: ', err);
reject(new Error('Internal server error'));
}
});
}
async signUp(request) {
const { email, name, password } = request;
await wait(1000);
return new Promise((resolve, reject) => {
try {
// Check if a user already exists
let user = users.find((user) => user.email === email);
if (user) {
reject(new Error('User already exists'));
return;
}
user = {
id: createResourceId(),
avatar: undefined,
email,
name,
password,
plan: 'Standard'
};
users.push(user);
const accessToken = sign({ userId: user.id }, JWT_SECRET, { expiresIn: JWT_EXPIRES_IN });
resolve({ accessToken });
} catch (err) {
console.error('[Auth Api]: ', err);
reject(new Error('Internal server error'));
}
});
}
me(request) {
const { accessToken } = request;
return new Promise((resolve, reject) => {
try {
// Decode access token
const { userId } = decode(accessToken);
// Find the user
const user = users.find((user) => user.id === userId);
if (!user) {
reject(new Error('Invalid authorization token'));
return;
}
resolve({
id: user.id,
avatar: user.avatar,
email: user.email,
name: user.name,
plan: user.plan
});
} catch (err) {
console.error('[Auth Api]: ', err);
reject(new Error('Internal server error'));
}
});
}
}
export const authApi = new AuthApi();
then /SRC/API/AUTH/data.js
export const users = [
{
id: '5e86809283e28b96d2d38537',
avatar: '/assets/avatars/avatar-anika-visser.png',
email: 'demo#devias.io',
name: 'Anika Visser',
password: 'Password123!',
plan: 'Premium'
}
];
This is the documentation on it
JSON Web Token (JWT)
Most auth providers use this strategy under the hood to provide access tokens. Currently, the app doesn't cover the backend service, and this service is mocked (faked) using http client interceptors. The implementation is basic, but enough to give you a starting point.
How it was implemented
Since tokens are meant to be created on the backend server, they are built with encrypt, encode and decode utility methods because they are not meant to be used on the client. These utilities can be found in src/utils/jwt. These are for development purposes only, and you must remove (or avoid using) them.
How to use JWT Provider
The app is delivered with JWT Provider as default auth strategy. If you changed or removed it, and you want it back, simply follow these steps:
Step 1: Import the provider
Open src/pages/_app.js file, import the provider and wrap the App component with it.
// src/pages/_app.js
import { AuthConsumer, AuthProvider } from '../contexts/auth/jwt-context';
const App = (props) => {
const { Component, pageProps } = props;
return (
<AuthProvider>
<Component {...pageProps} />
</AuthProvider>
);
};
Step 2: Set the hook context
Open src/hooks/use-auth.js file and replace the current context the following line:
import { AuthContext } from '../contexts/auth/jwt-context';
How to use auth
Retrieve user profile
In the example below, you can find how it can be used in any component not just the App. Should you want to use it in any other component, you'll have to import the useAuth hook and use it as needed.
// src/pages/index.js
import { useAuth } from '../hooks/use-auth';
const Page = () => {
const { user } = useAuth();
return (
<div>
Email: {user.email}
</div>
);
};
Auth methods / actions
For simplicity and space limitations, the code below is used only to exemplify, actual code can be found in the components.
// src/pages/index.js
import { useAuth } from '../hooks/use-auth';
const Page = () => {
const { login } = useAuth();
const handleLogin = () => {
// Email/username and password
login('demo#devias.io', 'Password123!');
};
s
return (
<div>
<button onClick={handleLogin}>
Login
</button>
</div>
);
};
Implemented flows
Currently, the app only covers the main flows:
Register
Login
Logout
const mongoose = require('mongoose');
const jwt = require("jsonwebtoken");
// Connect to MongoDB
mongoose.connect('mongodb://localhost/yourdbname', {
useNewUrlParser: true,
useUnifiedTopology: true
});
const userSchema = new mongoose.Schema({
id: {
type: String,
required: true,
unique: true
},
email: {
type: String,
required: true
},
name: {
type: String,
required: true
},
password: {
type: String,
required: true
},
plan: {
type: String,
default:
'Standard'
},
avatar: {
type: String,
default:
null
},
});
const User = mongoose.model('User', userSchema);
const JWT_SECRET = process.env.JWT_SECRET;
const JWT_EXPIRES_IN = '7d';
class AuthApi {
async signIn(request) {
const {
email,
password
} = request;
const user = await User.findOne({
email
});
if (!user || (user.password !== password)) {
throw new Error('Please check your email and password');
}
const accessToken = jwt.sign({
userId: user.id
}, JWT_SECRET, {
expiresIn: JWT_EXPIRES_IN
});
return {
accessToken
};
}
async signUp(request) {
const {
email,
name,
password
} = request;
const existingUser = await User.findOne({
email
});
if (existingUser) {
throw new Error('User already exists');
}
const newUser = new User({
id: mongoose.Types.ObjectId(),
email,
name,
password,
plan: 'Standard',
avatar: null,
});
await newUser.save();
const accessToken = jwt.sign({
userId: newUser.id
}, JWT_SECRET, {
expiresIn: JWT_EXPIRES_IN
});
return {
accessToken
};
}
async me(request) {
const {
accessToken
} = request;
const decoded = jwt.verify(accessToken, JWT_SECRET);
const {
userId
} = decoded;
const user = await User.findById(userId);
if (!user) {
throw new Error('Invalid authorization token');
}
return {

};
}
}
export const authApi = new AuthApi();
I have so far been unable to sort out this issue. I have a code that uses the MongoDb driver and whenever a do a fetch operation, i can no longer write to .response.body, e.g:
Once I call - await users.findOne({ email: req.email }) , I get an error when I do ctx.response.body.
As a workaround, is there a way i can force write the response, or a flag i can use to force oak not to close the response until i explicitly tell it to?
The error I get: The response is not writable.
Here is a sample snipped of my code:
private async create(context: Context, next: Function){
try {
interface UserSchema { email: string; password: string;}
const body = context.request.body()
assertEquals(body.type, 'json', 'app sent data in wrong format')
const req = await body.value
assertExists(req.email, 'email not provided')
assertExists(req.password, 'password not provided')
assertMatch(req.email, /(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|"(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*")#(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])/, 'this does not look like a valid email address')
assertMatch(req.password, /(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.{8,})/, 'password must contain: capital letter, small letter, number and must be 8 characters long')
const conn = context.state.db
const db = await conn.database('users')
const users = await db.collection<UserSchema>("users")
const user_id = await users.findOne({ email: req.email }) //bug *wont write to body
assert(!(user_id), 'email already exists')
const insertId = await users.insertOne({ email: req.email, password: req.password })
console.log('user added'); context.response.body = { 'error': false, 'msg': 'account created' }
} catch (e) { console.log({ 'error': e.name, 'msg': e.message })
//context.response.status = 500; context.response.body = { 'error': e.name, 'msg': e.message }
}
}
I have created an app that connects to a mongodb cluster and stores user info. The user is then able to log in with Next-Auth functionality. The app was working just fine before deploying to Vercel. On the live site I ran into some Server Config Errors. I refractored my code yet I am still running into a few errors.
I am successfully able to connect to the database for a new user sign up.
import {
connectToDatabase,
hashedPassword,
} from "../../helper/HelperFunctions";
const isEmpty = (value) => value.trim() === "";
const isTenChars = (value) => value.trim().length >= 10;
const emailValidation = (value) => {
const pattern = /^[^ ]+#[^ ]+\.[a-z]{2,3}$/;
if (value.match(pattern)) {
return true;
} else {
return false;
}
};
export default async function handler(req, res) {
if (req.method == "POST") {
let data = req.body;
const { firstName, lastName, email, password, userName } = data;
const firstNameIsValid = !isEmpty(firstName);
const lastNameisValid = !isEmpty(lastName);
const emailIsValid = emailValidation(email);
const passwordisValid = isTenChars(password);
const userNameIsValid = !isEmpty(userName);
let userDataIsValid =
firstNameIsValid &&
lastNameisValid &&
emailIsValid &&
passwordisValid &&
userNameIsValid;
if (!userDataIsValid) {
return;
}
const client = await connectToDatabase();
const db = client.db();
const existingUser = await db.collection("users").findOne({ email: email });
if (existingUser) {
res.status(422).json({ message: "User already exists, please log in!" });
console.log("User already exists, please log in!");
client.close();
return;
}
const protectedPassword = await hashedPassword(password);
await db.collection("users").insertOne({
firstName: firstName,
lastName: lastName,
email: email,
password: protectedPassword,
userName: userName,
});
client.close();
res.status(201).json({ message: "Signed up!" });
} else {
res.status(200).json({ data: req.body });
}
}
Here is my nextauth api route
import NextAuth from "next-auth/next";
import CredentialsProvider from "next-auth/providers/credentials";
// Helper Functions
import {
connectToDatabase,
comparePasswords,
} from "../../../helper/HelperFunctions";
export default NextAuth({
session: { strategy: "jwt" },
providers: [
CredentialsProvider({
async authorize(credentials) {
const client = await connectToDatabase();
const userCollection = client.db().collection("users");
const user = await userCollection.findOne({
email: credentials.email,
});
if (!user) {
client.close();
throw new Error("No user found!");
}
const isValid = await comparePasswords(
credentials.password,
user.password
);
if (!isValid) {
client.close();
throw new Error("Invalid password");
}
client.close();
if (user) {
return {
email: user.email,
};
} else {
return null;
}
},
}),
],
});
Before I deployed my site on Vercel, this was working just fine on localhost. The user should then proceed to a new page if the result of logging in has no errors.
const result = await signIn("credentials", {
redirect: false,
email: form.email,
password: form.password,
});
if (!result.error) {
console.log(true);
router.replace("/suggestions");
} else {
console.log(result.error);
setLoginResult(result.error);
}
If you see CLIENT_FETCH_ERROR make sure you have configured the NEXTAUTH_URL environment variable.
when developing you set it to localhost:3000, now you need to set that to your deployed url.
I am trying to test my API and I am not sure what I am doing wrong. The only error I am getting is cannot post. After some research, I am suspecting something wrong with my controller class.
This is my first real large project and I have created an API similar to this just with mongo but this is my first time using seqealize, and MySQL (with node).
The api/student/register router just won't post, but when I remove the controller and but a function that returns just plain JSON it works, that is why I really do believe it has something to do with my controller class.

I'm have an express server with MongoDB and Mongoose, and using passport to authenticate with JWT, but getting an error as in the title.
I'm following the passport-jwt documentation, but am still getting the error. What am I doing wrong?
Here is the error message when doing GET call on localhost3090 with a valid JWT:

You need to initialize the passport module before using it:
let app = express();
app.use(passport.initialize());
