I've been writing an experimental pipeline-based web app DSL with Claude Code for the last little while in my spare time. Sort of bash-like with middleware for lua, jq, graphql, handlebars, postgres, etc.

Here's an already out of date and unfinished blog post about it: https://williamcotton.com/articles/introducing-web-pipe

Here's a simple todo app: https://github.com/williamcotton/webpipe/blob/webpipe-2.0/to...

Check out the BDD tests in there, I'm quite proud of the grammar.

Here's my blog: https://github.com/williamcotton/williamcotton.com/blob/mast...

It's got an LSP as well with various validators, jump to definitions, code lens and of course syntax highlighting.

I've yet to take screenshots, make animated GIFs of the LSP in action or update the docs, sorry about that!

A good portion of the code has racked up some tech debt, but hey, it's an experiment. I just wanted to write my own DSL for my own blog.
