In this 19-video course, learners will discover how to orchestrate technologies making up the MEAN (MongoDB, Express, Angular, and Node) stack to create a basic authentication application based on Javascript. Begin by examining key considerations followed when planning a MEAN application, and learn how to prepare the environment by installing Node, Express, and dependencies for full-stack Angular application for full stack development. Then learn how to create a new project with Angular CLI (command-line interface); add Angular Material design components; and create a working mock-up with Angular components and templates. Next, watch how to add a Node in Express backend server, build an API (application programming interface) route with Express, and validate request body payloads. Learn to configure JWT (JSON Web Token) authentication, use middleware in a MEAN application, create and execute unit tests, and learn how to handle errors. Next, see how to create a MongoDB Atlas account; connect MongoDB with Mongoose; and use a MongoDB and Mongoose to build data models. Finally, learn to prepare and deploy a MEAN application to Heroku Cloud-based platform-as-a-service.
