海外TECH	DEV Community	Authentication with middlewares in NextJS	https://dev.to/brainiacneit/authentication-with-middlewares-in-nextjs-279p	Authentication with middlewares in NextJS OverviewHey there Today we re going to talk about authentication in Next js using middlewares If you re not familiar Next js is a really cool framework for building server rendered React applications So what s authentication all about Well it s a way to make sure that only the right people can access certain parts of your web app And that s where middlewares come in handy They re like helpers that can do certain things before requests reach the actual route handlers This article will discuss the fundamentals of middlewares and demonstrate how they can be utilized in a Next js application to establish a secure authentication system Upon reading this article you ll acquire a comprehensive understanding of how to utilize middlewares for authentication in Next js and have the ability to enhance the security of your web apps Let s begin and explore the world of authentication with Next js Set up PackagesFirst we have to have a NextJS project then install Axios for better HTTP Handlingyarn add axios ServicesNext we have to define a service in this case AuthService to handle authentication import axios AxiosInstance from axios export class AuthService protected readonly instance AxiosInstance public constructor url string this instance axios create baseURL url timeout timeoutErrorMessage Time out login username string password string gt return this instance post login username password then res gt return username res data username avatar res data avatar id res data userId accessToken res data access token expiredAt res data expiredAt This code defines a class named AuthService that exports it as a module The AuthService class has a constructor that takes a URL as a parameter to create an Axios instance based on that URL Axios is a popular JavaScript library used to make HTTP requests from a web browser or Node js The login method is defined within the AuthService class which takes two parameters username and password This method sends a POST request to the login endpoint of the API service using the Axios instance created in the constructor The username and password are passed as an object in the POST request body If the POST request is successful the method returns an object that contains the username avatar id accessToken and expiredAt properties These properties are extracted from the response data which is received from the API service Overall this code defines a reusable AuthService class that encapsulates the logic for making an HTTP request to an API service to log in a user and retrieves the user s information Routesexport const protectedRoutes profile export const authRoutes login export const publicRoutes about We need types of routes Protected routes only logged in users can access these routesAuth routes routes that serve authentication authenticated users can t access these routesPublic routes routes that can be accessed by anyone Login hookWe need a hook to handle login function import authService from services import Cookies from js cookie import User from types user export const useLogin gt const login async username string password string gt const user await authService login username password if user Cookies set currentUser JSON stringify user return user as User return login This code exports a function named useLogin that returns an object with the login function The login function takes two parameters username and password Within the login function an asynchronous call is made to authService login username password which is a method defined in another module authService This method returns a promise that resolves to a User object If the User object is truthy meaning it exists the Cookies set method is called to set a cookie named currentUser with the stringified User object as its value Finally the login function returns the User object as a type assertion to inform TypeScript that the returned value is indeed a User MiddlewareThis is the most important part of the article using built in middleware ts of NextJS import NextResponse from next server import type NextRequest from next server import authRoutes protectedRoutes from src router routes export function middleware request NextRequest const currentUser request cookies get currentUser value if protectedRoutes includes request nextUrl pathname amp amp currentUser Date now gt JSON parse currentUser expiredAt request cookies delete currentUser const response NextResponse redirect new URL login request url response cookies delete currentUser return response if authRoutes includes request nextUrl pathname amp amp currentUser return NextResponse redirect new URL profile request url This code defines a middleware function that is used in a Next js application Middlewares are functions that can modify incoming requests and outgoing responses in a web application The middleware function takes a NextRequest object as its parameter which is provided by the Next js server The NextRequest object represents an incoming request and contains information about the URL headers cookies and other request specific data The middleware function first retrieves the currentUser cookie from the request using request cookies get currentUser value If the requested URL is a protected route defined in protectedRoutes and the currentUser cookie is not present or has expired the middleware will delete the currentUser cookie and redirect the user to the login page using NextResponse redirect new URL login request url The response cookies delete currentUser statement removes the currentUser cookie from the response object If the requested URL is an authentication route defined in authRoutes and the currentUser cookie is present the middleware will redirect the user to the profile page using NextResponse redirect new URL profile request url ConclusionIn conclusion this article has covered the fundamentals of authentication using middlewares in Next js We ve discussed how middlewares can be used to manage authentication in web applications by intercepting incoming requests and performing necessary actions before they reach the actual route handlers We ve also explored how to implement a secure authentication system using middlewares in a Next js application If you find this article is too confusing you can check out the source code	2023-08-13 03:14:33
