In this tutorial, you will learn how to build a full-stack web application that performs CRUD (Create, Read, Update, Delete) operations using Angular for the front-end, Node.js for the back-end, MongoDB as the database, and REST API for communication between the front-end and back-end.
Overview
CRUD operations are the fundamental operations of most web applications. CRUD is an acronym that stands for Create, Read, Update, and Delete. These operations correspond to the HTTP methods POST, GET, PUT, and DELETE respectively. In this tutorial, we will build an Angular application that communicates with a Node.js server via RESTful APIs to perform these operations on a MongoDB database.
Prerequisites
Before you begin, make sure you have the following installed:
Node.js and npm
Angular CLI
MongoDB
Step-by-Step Guide
Set up the Backend with Node.js and Express
Create Angular Components
Generate components for listing, creating, updating, and deleting users:
ng generate component user-list
ng generate component user-form
Implement the logic in your components to call the service methods and handle user interactions.
Run the Application
Start the Node.js server:
node index.js
Run the Angular application:
ng serve
Open your browser and navigate to localhost:4200 to see your Angular application in action.
Conclusion
By following this tutorial, you have learned how to create a full-stack application that performs CRUD operations using Angular, Node.js, MongoDB, and REST API. This setup is a solid foundation for building robust and scalable web applications.
