insane VS remark

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)

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.

Both Remark and Rehype are frameworks to transform documents by first transforming them to abstract syntax trees (AST) and then applying pluggable functions to the AST before converting it to the target format.

remarkjs/remark: markdown processor powered by plugins part of the @unifiedjs collective

I also didn't try this tool but it's called RemarkJS which is named too similar to revealjs.

remark. Primarily, this is a linter for Markdown. Additionally, thanks to its numerous plugins, it allows us to perform additional checks for grammatical mistakes within the content itself. Before using this linter, our content was not scrutinized to this extent.

Rehype and Remark are plugins used to transform and manipulate the HTML and Markdown content of a website, helping to enhance its functionality and appearance.

I usually combine remark-parse, remark-rehype and rehype-react to transform markdown into react components. The configuration of the processor is like:

Astro content collection are as simple as a folder containing a bunch of Markdown (or Markdoc or MDX) files if that's the only thing you need, but they can also do relationship matching between different collections, frontmatter validation using zod and you can also customize how the markdown is parsed and translated to html using rehype and remark and their plugin ecosystem.

On my personal blog I have few external links in my posts. I wanted to keep people on my website by applying target="_blank" on external (those what don't reference to my site) links. This is a common and good practice too. I write my content in Markdown, so I decided to write a remark plugin. It is simple to implement, just few lines of code.

Although we are building a custom table of contents, we won't have to write everything from scratch. To separate the Markdown/MDX content from the front matter, we'll use the Gray-matter package. It is optional in case you don't have front matter in your Markdown files. To process the Markdown itself, we'll use the Remark package. We'll also need the unist-util-visit package for traversing node trees and mdast-util-to-string for getting the text content of a node.

That's all to render the post as HTML, there are lots of things you can do to customize the results, you can check the remark plugins and rehype plugins to pass as props to and you can also take a look at some other bloggers if you're looking for different styles for example Lee Robinson's or if you liked mine.
