Yesterday, I bought the Claude Pro subscription, to see how it compares to ChatGPT and… I started having too much fun :D. I started planning out a programming project that I wanted to do for a long time. For that, I started playing with the “Projects” feature they offer, where you essentially attach files that make up the base of knowledge for that project.

But… I was a bit stuck. The place where I wanted to gather this knowledge was Notion, in a page that referenced more subpages. So my thinking went that hey, I’ll just export the Notion pages and upload them to Claude. But there was a little problem: Notion exports multiple files if you use sub-pages.

So what, you upload 10 files to the knowledge base only to have to manually remove them and re-add the new export, for when you change something??? And what if I want to upload the code too?? Blasphemy! I’m a programmer, I can do better! >:(

This “better” is *Prompt Packer* - a little CLI that lets you bundle the files in your project into one .txt file that you just give Claude. It’s somewhat smart, meaning that it ignores files that shouldn’t end up in a prompt (images, node_modules/, dist/, etc.), but you can also give it patterns to ignore. And the output can actually be understood by an LLM, as it’s prefixed with a prompt.

So there it is, the first NPM package I’ve published after about 5 honest hours of work! :D Let me know what you think (and maybe give it a star on GitHub? :D). I have a feeling that I’ve solved an already solved problem with this, so if there was another way let me know. If not, I hope you make good use of the tool as well!

Anyways, I've personally had fun building this little thing. Now let’s get to building the actual project I had in mind ^^.
