Show HN: Markdown HN profiles at {user}.at.hn
Since marked doesn't do it for you, make sure you sanitize the user input (the text on the user profiles) before rendering it to visitors.
Some libraries for doing that with good defaults:
- https://github.com/cure53/DOMPurify
- https://github.com/apostrophecms/sanitize-html
- https://github.com/bevacqua/insane
(right now your site looks vulnerable to XSS)

What tools do you use to generate css/xpath selectors?
Sometimes I use sanitize-html to clean up the html and ask chatgpt to help me refine my selectors.

Add Mastodon replies to your blog
One thing to watch out for is that the content of each reply is HTML. To be safe (paranoid), I'm running the HTML through sanitize-html to make sure nobody can inject sketchy HTML into my site.

Made an IMDB application using the TMDB API. The design is a bit similar to what you find on a streaming website. I made this with HTML, SCSS & Vanilla JS. Tips, feedback & suggestions would be greatly appreciated.
Don't forget to sanitize your HTML using https://github.com/apostrophecms/sanitize-html or upcoming feature: https://developer.mozilla.org/en-US/docs/Web/API/HTML_Sanitizer_API because https://nimb.ws/leTXDt

How To Parse and Render Markdown In Vuejs
Vue does not have as much support for Vue as there is for React. Examples are markdown-it, Remark.js, marked.js. But hopefully in the future, there should be more support, and after much research, I picked marked.js because it has the most stars and has zero vulnerability. Marked does not sanitize (meaning it does not secure HTML documents from attacks like cross-site scripting (XSS) ) marked output HTML as that feature is deprecated and has vulnerability but however, it supports the use of other libraries to secure output HTML such as DOMPurify (recommended), sanitize-html or insane.
