To develop the user authentication feature in the 'E-Commerce Platform' project, follow this structured workflow:

1. **Requirement Analysis**: Gather and document all authentication requirements, including user roles, permissions, and security protocols. Ensure compliance with GDPR and other relevant regulations.
2. **Design Phase**: Create wireframes and UI mockups using Figma. Include login, registration, and password recovery screens. Ensure the design is responsive and accessible.
3. **Development Setup**: Set up the development environment with Node.js and React. Integrate with the existing backend using RESTful APIs. Use JWT for secure authentication.
4. **Implementation**: Develop the authentication logic, including user registration, login, and session management. Implement role-based access control (RBAC) to manage user permissions.
5. **Testing**: Write unit tests using Jest and integration tests using Postman. Conduct security testing to identify vulnerabilities. Use automated testing tools like Selenium for UI testing.
6. **Deployment**: Deploy the feature to the staging environment for QA testing. Once approved, deploy to the production environment using CI/CD pipelines. Monitor the feature for performance and security issues.

**Best Practices**:
- Use environment variables to manage sensitive data.
- Implement rate limiting to prevent brute force attacks.
- Regularly update dependencies to patch security vulnerabilities.

**Common Pitfalls**:
- Inadequate input validation can lead to security breaches.
- Poor error handling can frustrate users and impact the user experience.
- Insufficient testing can result in bugs and performance issues.
