This application is the backend of a CRM system. Users will be able to make HTTP requests to the server to perform basic CRUD operations. A user can get all the customers from the mock database, get a single user by ID, create a new user, update an existing user or delete a user by ID.

To launch the project, run the following command from the root directory of the project: go run main.go. The application runs on localhost port 3000.

This is an overview of the available operations that are supported, together with the available endpoints:

• (GET) Get a single customer: /customers/{id}
• (GET) Get all customers: /customers
• (POST) Create a new customer: /customers
• (PUT) Update an existing customer: /customers/{id}
• (DELETE) Delete a customer: /customers/{id}

Example: curl command - POST request for creating a new user:

curl --location --request POST 'http://localhost:3000/customers' \
--header 'Content-Type: application/json' \
--data-raw '    {
        "Id": 4,
        "Name": "Jon",
        "Role": "Customer",
        "Email": "[email protected]",
        "Phone": "1234543210",
        "Contacted": false
    }'
