Conclusion About the author In this article, we will explore the essential rules to implement in the back-end of an application, with a special focus on user registration and login. We will cover topics such as validating input data, verifying existing.
Users, encrypting passwords, authenticating with JWT, and integrating with the MongoDB database. These practices are fundamental to ensuring the security and efficiency of the system, in add Austria Mobile Number List ition to providing a positive experience for users. Input data validation When dealing with user registration and login in an application, it is crucial to carry out validations on the input data to ensure that it is in the correct format, preventing future problems. Some essential validations include: Checking whether email is mandatory Validation of password mandatory error return (Bad Request) if the email or password are not sent Checking existing user Before registering a new user, it is essential to check whether the user is already registered in the database. To do this, it is possible to carry out a consultation via email before entering the record. Additionally.
Important practices include: Checking the existence of the email in the database Error return in case of already registered user User password encryption The security of user information is of utmost importance, and password encryption is a fundamental practice to protect data. By encrypting the user's password, it ensures that sensitive information remains secure. Furthermore, it is important to consider: Using secure algorithms for encryption Implementation of good data security practices JWT token generation To keep the user logged in securely and efficiently, generating a JWT token is a best practice. This token is used to authenticate and authorize the user, offering an additional layer of security. When implementing JWT token generation, it is important to: Using trusted libraries for generating and validating tokens Proper Token Expiration Time.
