In this tutorial, we’ll guide you through the steps to build a CRUD (Create, Read, Update, Delete) web application using the MEAN stack with Angular 5. This stack combines MongoDB, Express.js, Angular, and Node.js to create a powerful application.

Prerequisites

• Node.js installed on your machine
• Basic knowledge of JavaScript and Angular
• Familiarity with MongoDB and REST APIs

Step-by-Step Instructions

Follow these steps to get your application up and running locally:

1. Clone the Repository: Start by cloning the repository to your local machine. Open your terminal and run:

git clone https://www.djamware.com/post/5a0673c880aca7739224ee21/mean-stack-angular-5-crud-web-application-example

2. Install Dependencies: Navigate into your cloned directory and install the necessary packages using npm:

cd mean-stack-angular-5-crud
npm install

3. Run the Application: Start the server by running:

npm start

Your application will be running locally. Open a web browser and go to http://localhost:3000 to see it in action!

Understanding the Code with an Analogy

Imagine building a small restaurant. Each part of the MEAN stack contributes to creating an efficient dining experience:

• MongoDB: Think of it as your pantry where all the ingredients (data) are stored. It allows you to access ingredients whenever needed for your dishes (requests).
• Express.js: This is the head chef who manages the kitchen (server). It handles all your customers’ orders (HTTP requests) and decides how to prepare each dish.
• Angular: Picture this as the waitstaff that takes your customers’ orders and brings them to the table. It presents the information beautifully on the front end.
• Node.js: This acts as the restaurant’s backend structure ensuring everything runs smoothly and efficiently, connecting the kitchen to the pantry and to the waitstaff.

Troubleshooting Common Issues

If you encounter any problems while running your application, consider the following:

• Make sure you have the latest version of Node.js installed.
• Ensure that you have installed all dependencies without any errors.
• If the application doesn’t start, try running npm install -g nodemon to install nodemon which helps to restart your server automatically.
• Check the console for any error messages that might indicate what’s going wrong.
