Could you build this?
Partial While scaffolding a basic reactive UI runtime or compiler prototype is feasible with AI, engineering a complete frontend ecosystem (custom parser/compiler, reactivity system, router, CLI, devtools, and edge runtime support) requires deep systems-level JavaScript engine expertise.
What it would actually take: Building OlumJS requires developing an AST parser and compiler pipeline (using Babel or SWC) that converts single-file HTML components into optimized DOM update operations. The reactivity engine must handle fine-grained updates or dirty-checking without overhead, paired with custom Vite/esbuild plugins, a file-based CLI router, and IDE Language Server Protocol (LSP) plugins. This demands deep compiler engineering and web platform internals expertise.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
