User Resource Module And Schema

by ADMIN 32 views

Overview

Implementing a User resource module and schema is a crucial step in building a robust authentication system. This module serves as the foundation for user management, defining the core user data structure with necessary fields for authentication and authorization. In this article, we will delve into the details of designing a User schema, implementing CRUD operations, data validation, and database integration.

User Schema Design

A well-designed User schema is essential for a secure and efficient authentication system. The schema should include fields for username, email, password (hashed), roles, and account status. Additionally, timestamp fields such as created, updated, and last login should be included to track user activity.

User Schema Fields

  • username: A unique identifier for the user, typically a string of characters.
  • email: The user's email address, used for password recovery and communication.
  • password: A hashed version of the user's password, stored securely.
  • roles: An array of roles assigned to the user, such as admin, moderator, or user.
  • account_status: A field indicating the user's account status, such as active, suspended, or deleted.
  • created: A timestamp indicating when the user account was created.
  • updated: A timestamp indicating when the user account was last updated.
  • last_login: A timestamp indicating the user's last login attempt.

Timestamp Fields

Timestamp fields are essential for tracking user activity and ensuring data integrity. The created field records the date and time when the user account was created, while the updated field records the date and time when the user account was last updated. The last login field records the date and time of the user's last login attempt.

Failed Login Attempts

To prevent brute-force attacks, it's essential to track failed login attempts. This can be achieved by adding a field to track the number of failed login attempts within a specified time frame.

User Schema Example

CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  username VARCHAR(255) NOT NULL,
  email VARCHAR(255) NOT NULL,
  password VARCHAR(255) NOT NULL,
  roles JSONB NOT NULL,
  account_status VARCHAR(255) NOT NULL,
  created TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  updated TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  last_login TIMESTAMP,
  failed_login_attempts INTEGER NOT NULL DEFAULT 0
);

User Resource API

The User resource API is responsible for managing user data, including registration, profile updates, and account management. The API should provide CRUD (Create, Read, Update, Delete) operations for user management.

CRUD Operations

  • Create: Create a new user account with the provided credentials.
  • Read: Retrieve a user's account information by their username or email.
  • Update: Update a user's account information, including their profile and password.
  • Delete: Delete a user's account, including their associated data.

API Endpoints

  • POST /users: Create a new user account.
  • GET /users/{username}: Retrieve a user's account information by their username.
  • PUT /users/{username}: Update a user's account information.
  • DELETE /users/{username}: Delete a user's account.

Data Validation

Data validation is essential to ensure that user input is valid and secure. The API should implement validation for user inputs, including email format, password strength, and other relevant fields.

Validation Rules

  • Email format: Validate that the email address is in a valid format.
  • Password strength: Validate that the password meets the required strength criteria.
  • Username format: Validate that the username is in a valid format.

Validation Example

const validateEmail = (email) => {
  const emailRegex = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/;
  return emailRegex.test(email);
};

const validatePassword = (password) => {
  const passwordRegex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])[A-Za-z\d@$!%*?&]{8,}$/;
  return passwordRegex.test(password);
};

const validateUsername = (username) => {
  const usernameRegex = /^[a-zA-Z0-9_]{3,20}$/;
  return usernameRegex.test(username);
};

Database Integration

The User resource module should be integrated with a database to store user data. The database should be properly configured and indexed for efficient queries.

Database Configuration

  • Database type: Choose a suitable database type, such as PostgreSQL or MySQL.
  • Database connection: Establish a connection to the database using a suitable driver.
  • Database schema: Define the database schema to match the User schema.

Database Indexing

  • Indexing: Index the User schema fields to improve query performance.
  • Index types: Choose suitable index types, such as B-tree or hash indexes.

Acceptance Criteria

The User resource module should meet the following acceptance criteria:

  1. A complete User schema is implemented with all necessary fields.
  2. CRUD operations for User resource are functional.
  3. Input validation is in place for all user data.
  4. Database integration is configured and working properly.
  5. User registration flow is implemented.
  6. Basic tests for the User resource are passing.

Technical Considerations

When designing the User schema and implementing the User resource module, consider the following technical considerations:

  • Schema design: Design the schema to accommodate future authentication features.
  • Indexing: Ensure the User model is properly indexed for efficient queries.
  • Best practices: Follow best practices for database schema design.
  • Documentation: Document the API endpoints and schema structure.
