Hello everyone, today we will learn how to build a full-stack application that is a basic User Management Application using Node.js , MongoDB , and Vue.js . GitHub repository link is provided at the end of this tutorial. You can download the source code. Node.js Express exports REST APIs & interacts with MongoDB Database utilizing Mongoose ODM . Vue.js is an open-source, progressive JavaScript framework for building utilizer interfaces. Vue fortifies the component-based approach to building web apps – it includes single-file components that are independent and loosely coupled to enable better code reuse and more expeditious development After completing this tutorial what we will build?   We will build a full-stack web application that is a basic User Management Application with CRUD features:  Create User  List User Update User Delete User  Following is the screenshot of our application - -Retrieve all Users: -Add a User: -Update User: We divided this tutorial into two parts.
