Description

Developing the Admin User APIs is a crucial step in managing user retrieval and generating system reports. This article will guide you through the process of implementing the necessary endpoints with proper validation and authentication.

Core Features

The Admin User APIs will have the following core features:

Retrieve all users: This feature will allow admins to retrieve a list of all users in the system.
Retrieve a single user: This feature will enable admins to retrieve the details of a specific user.
Generate user system reports: This feature will allow admins to generate system reports that are filterable by weeks, months, and years.

Backend Implementation

To implement the Admin User APIs, we will create the following endpoints with proper validation and authentication:

GET `/admin/all-users` – Retrieve user list

This endpoint will be responsible for retrieving a list of all users in the system. To implement this endpoint, we will use the following steps:

Create a DTO: We will create a DTO (Data Transfer Object) to validate the input data. The DTO will contain the necessary fields to retrieve the user list.
Implement the endpoint: We will implement the endpoint using the NestJS framework. We will use the @Get decorator to define the endpoint and the @Param decorator to inject the required parameters.
Validate the input: We will use the DTO to validate the input data. If the input data is invalid, we will return an error response.
Retrieve the user list: We will use the validated input data to retrieve the user list from the database.
Return the response: We will return the user list in the response.

GET `/admin/users/id` – Retrieve single user

This endpoint will be responsible for retrieving the details of a specific user. To implement this endpoint, we will use the following steps:

Create a DTO: We will create a DTO to validate the input data. The DTO will contain the necessary fields to retrieve the user details.
Implement the endpoint: We will implement the endpoint using the NestJS framework. We will use the @Get decorator to define the endpoint and the @Param decorator to inject the required parameters.
Validate the input: We will use the DTO to validate the input data. If the input data is invalid, we will return an error response.
Retrieve the user details: We will use the validated input data to retrieve the user details from the database.
Return the response: We will return the user details in the response.

GET `/admin/user/reports` – Generate user system reports

This endpoint will be responsible for generating system reports that are filterable by weeks, months, and years. To implement this endpoint, we will use the following steps:

Create a DTO: We will create a DTO to validate the input data. The DTO will contain the necessary fields to generate the system reports.
Implement the endpoint: We will implement the endpoint using the NestJS framework. We will use the @Get decorator to define the endpoint and the @Query decorator to inject the required parameters.
Validate the input: We will use the DTO to validate the input data. If the input data is invalid, we will return an error response.
Generate the system reports: We will use the validated input data to generate the system reports.
Return the response: We will return the system reports in the response.

Requirements

To implement the Admin User APIs, we will ensure that the following requirements are met:

Authentication and role-based authorization: We will implement authentication and role-based authorization to ensure that only admins can access the endpoints.
Validation of all inputs: We will use DTOs to validate all inputs to ensure that the data is correct and consistent.
Implementation of guards and middleware: We will implement guards and middleware to ensure that the endpoints are properly secured and protected.
Follow best practices for API design and security: We will follow best practices for API design and security to ensure that the endpoints are properly designed and secured.

Acceptance Criteria

To ensure that the Admin User APIs are properly implemented, we will use the following acceptance criteria:

All endpoints should be functional and secured: We will ensure that all endpoints are properly implemented and secured.
Admins should be able to retrieve user lists and individual user details: We will ensure that admins can retrieve user lists and individual user details.
System reports should be filterable by time periods (weeks, months, years): We will ensure that system reports are filterable by time periods (weeks, months, years).

References

To implement the Admin User APIs, we will use the following references:

NestJS Authentication & Authorization Docs: We will use the NestJS authentication and authorization documentation to implement authentication and role-based authorization.
API Best Practices: We will use API best practices to ensure that the endpoints are properly designed and secured.

Frequently Asked Questions

In this article, we will answer some of the frequently asked questions related to implementing the Admin User APIs.
