Hey everyone! I'm working on my website and I've got a textarea where users can edit rich text, along with another section for breaking lines and whatnot. I'm wondering how I should store this rich text both on the front-end and the back-end. I can use different classes or tags to style it on the front-end, but I need a strategy for saving and retrieving this data so it displays correctly elsewhere. What's the best approach for handling this?

Typically, you’ll get rich text as HTML if that's what your editor supports, and then you should validate and sanitize it on the server-side. Only allow specific elements and attributes to avoid security issues. Look for reputable sanitizing libraries in your programming language for this—it can be tricky to get right!
I'd recommend using HTML since it's pretty easy to parse. Just keep in mind to sanitize it properly before saving!
The way you store rich text really depends on the rich text package you're using. Some packages, like Lexical, save data as JSON, while others save it as HTML. Just a heads up—if you're going the HTML route, it's super important to sanitize user inputs because you can't trust them to be secure.
Markdown could be a great fit depending on your needs. It's what powers the reddit text editor! It allows for some formatting while being plain text, which reduces the risk of injection attacks compared to HTML.
