A lightweight, tiny package alternative to popular React Markdown renderers (with Katex and Prism.js) that bundle 300kb+ of JS. Focuses on minimal bundle size and specific use cases, accepting 'not correct' parsing via Regex for common Markdown.
This product directly addresses a critical developer pain point: excessive bundle size in web applications. Existing Markdown and LaTeX renderers for React are identified as significantly contributing to application bloat. LLMRender's value proposition is its minimal footprint (10kb), offering a performance advantage for applications where every kilobyte matters, particularly in mobile-first or resource-constrained environments. The trade-off of using Regex over a full AST parser, while technically 'incorrect,' is deemed acceptable for the majority of Markdown use cases, prioritizing performance and size over absolute parsing correctness. This highlights a market trend towards highly optimized, purpose-built components that sacrifice broad compatibility for specific performance gains, appealing to developers focused on lean web delivery.
I've been using the popular React Markdown renderers with Katex and Prism.js for rendering my Markdown and LaTeX, but was tired of having to bundle 300kb+ of min+gzip JS only for this (1.2MB+ of plain JS!). So I created a small Markdown renderer that does it all in a tiny package.I added a small playground to the homepage, please feel free to try it and let me know what you think!It's not perfect, it's definitely not "correct" in that I'm using Regex internally instead of a proper AST parser, but for my usecase and the majority of Markdown out there, this works perfectly fine (cue the StackOverflow post [1]). It's also conservative for this reason; no HTML by default, parsing wrong content produces escaped HTML entities instead of XSS.[1] https://stackoverflow.com/a/1732454
