Stoic

A small, client-only, fine-grained reactive UI engine with a Solid 2-like API, written in TypeScript. It's a hobby project, mostly for learning and for building small personal apps.

Goals

• Minimal API close to Solid 2.
• JSX without compiler.
• Svelte-like transitions.
• Small enough for one person to understand fully.

Non-goals: SSR, hydration, devtools, held/atomic async transitions.

The full roadmap is in the-big-plan.md.

State

Early work in progress. The reactive core is in src/ and has tests:

• Signals (with custom equality)
• Memos and writable memos
• Effects and ownership tree
• JSX runtime
• Control flow (Show, For, ...)
• Async
• Stores
• Actions
• Transitions
• Public API docs

AI disclosure

The project roadmap & most unit tests are written by LLMs. The library code is hand-written.
