Features

1. Lightweight and framework agnostic: ByteMD is built with Svelte. It compiles to vanilla JS DOM manipulation without importing any UI Framework runtime bundle, which makes it lightweight, and easily adapted to other libraries/frameworks.
2. Easy to extend: ByteMD has a plugin system to extend the basic Markdown syntax, which makes it easy to add additional features such as code syntax highlight, math equation and Mermaid flowcharts. You can also write your own plugin if these ones don't meet your needs.
3. Secure by default: Cross-site scripting(XSS) attack such as <script> and <img onerror> have been correctly handled by ByteMD. No need to introduce extra DOM sanitize steps.
4. SSR compatible: ByteMD could be used in the Server-side rendering(SSR) environment without extra config. SSR is widely used in some cases due to its better SEO and fast time-to-content in slow network connection.
