If it didn't, open http : / / localhost:4040 /. 🛠 Open a separate terminal window and execute the following command to serve the user interface of your Express app: npm run uiīrowsersync automatically opens a new window presenting your application user interface. The browser will refresh automatically whenever the source code changes: for example, when you modify a CSS rule or change the return value of a function. You can emulate the live reload behavior of front-end frameworks such as React and Angular in Express templates using Browsersync.

🛠 Execute the following command to run the Node.js server: npm run dev To streamline your Node.js development workflow, this project uses nodemon to restart the server and browser -sync to reload the browser whenever relevant source files change. env as follows: DEV_PORT = 4041 PROD_PORT = 4040 env file under the project directory: touch. 🛠 Install the Node.js project dependencies: npm install 🛠 As such, clone the auth0 -express -pug -sample repository on its starter branch to get started: git clone -b starter Once you clone the repo, make auth0 -express -pug -sample your current directory: cd auth0-express-pug-sample You can focus on building Express components to secure your application. The starter application uses Bootstrap with a custom theme to take care of the styling and layout of your application. We have created a starter project to help you learn Node.js security concepts through hands-on practice. ⏰⚡️ If you are short of time, check out the Auth0 Express Quickstart to get up and running with user authentication for Express in just a few minutes. Once your users log in successfully, Auth0 takes them back to your app, returning JSON Web Tokens (JWTs) with their authentication and user information. Your application will then redirect users to an Auth0 customizable login page when they need to log in. You first integrate your application with Auth0. With the help of Auth0, you don't need to be an expert on identity protocols, such as OAuth 2.0 or OpenID Connect, to understand how to secure your web application stack. ⚠️ If you still need to use Passport.js to secure your Express application, please refer to the Node.js and Express Authentication Using Passport tutorial. Express OpenID Connect lets you add user authentication to Express applications using security best practices while writing less code.

This library provides Node.js developers with an alternative to Passport.js. This guide uses the Auth0 Express OpenID Connect library to secure Express web applications. You'll enhance a starter Node.js project to practice the following security concepts: This tutorial demonstrates how to secure a Node.js web application built with the Express framework by implementing user authentication. Look for the 🛠️️ emoji if you'd like to skim through the content while focusing on the build steps.
