How can I sanitize user input to protect against security vulnerabilities in NextJS?

I’m working on a couple low level apps that take some user input and post to a database. The data itself isn’t really sensitive, but I want to make sure I’m not making dumb mistakes and allow XSS or similar. I just started using NextJS and have not yet started to dig into XSS and related.

You can use the NextJS built-in sanitization library to sanitize user input. This library provides a set of functions that can be used to sanitize user input and protect against security vulnerabilities. For example, you can use the sanitizeHtml function to sanitize HTML input, or the sanitizeCss function to sanitize CSS input.
