Web Programming with Hoplon

on YouTube ↗41m

" summary

Hoplon is a ClojureScript framework that builds pages from S-expressions, compiles .hl files to JS, and wires a reactive core called Javelin (abstract spreadsheet) where cells hold any value (including collections) and formula cells update by equality checks not dirty checking. UI elements are native DOM elements, no virtual DOM, invocable via IFn; attributes dispatch to multimethods. Server side uses Castra RPC with CQRS and Datomic-friendly polling so clients fire commands and receive a single state query back, which consistently percolates into cells.
