Building Secure REST API in Node.js

Input validation ensures that the API only processes expected and properly formatted data, lowering the risk of security vulnerabilities such as SQL injection and XSS.

Keep track of software updates and apply them as soon as possible to ensure you have the most recent security patches. To automate the process of keeping dependencies updated, use package managers and dependency management tools.

Encryption protects sensitive data, such as passwords and financial information, by converting it into a coded format that unauthorized parties cannot easily understand.

There are several popular Node.js frameworks available for building RESTful APIs, and the choice of framework often depends on your specific requirements and preferences. However, some of the most commonly used and well-regarded Node.js frameworks for building RESTful APIs are:

• Express
• Koa
• Hapi
• Nest.js

It's always a good idea to research and evaluate multiple frameworks before selecting the one that best fits your needs.

Hashing is used to securely store sensitive data such as passwords. It converts plain text into a one-of-a-kind string of characters that cannot be reversed.

REST (Representational State Transfer) is a software architectural style for building distributed systems, including web services like RESTful APIs. While REST itself does not have built-in security features, it provides a set of constraints and principles that can be used to design secure web services.

When building a RESTful API, it is up to the developer to implement security measures to protect against common security threats, such as unauthorized access, injection attacks, and cross-site scripting (XSS) attacks. Some common security measures that can be implemented in a RESTful API include:

• Authentication
• Encryption
• Authorization
• Input validation

In summary, while RESTful APIs do not have built-in security features, developers can implement a variety of security measures to ensure the safety and integrity of their web services. It's important to carefully consider the security requirements of your API and choose appropriate security measures to mitigate potential security risks.
