Meemaw

Problem Statement

React JSX is littered with the same noisy patterns: ternaries for conditional rendering (isLoggedIn ? <A/> : <B/>), nested ternaries for multi-branch logic, .map() boilerplate for iteration, ad-hoc breakpoint checks for responsive hiding, and one-off clipboard handlers. Individually trivial, collectively they make components harder to read and review. Every project re-implements them.

Proposed Solution

Meemaw is a tiny, zero-dependency React utility library of declarative components that replace those patterns with readable, intention-revealing markup — <Show>, <Switch>/<Case>/<Default>, <Hidden>, <Repeat>, <Clamp>, <CopyToClipboard> and more — so the JSX reads like what it does.

Full Solution Details

• <Show when={...} fallback={...}> — conditional rendering with an optional fallback and a when/if alias; replaces the ubiquitous ternary.
• <Switch>/<Case when={...}>/<Default> — a clean match-case for multi-branch UI (order status, role, etc.) instead of nested ternaries.
• <Hidden when={...}> / <Hidden on="mobile"> — conditional and responsive hiding by breakpoint (['mobile','tablet']), no manual media-query hooks.
• <Repeat> — declarative iteration without .map() ceremony.
• <Clamp> — time/length-based display constraints.
• <CopyToClipboard> — drop-in clipboard behavior.
• 9 components total, each importable individually.

Technical Documentation

Pure React + TypeScript with React as the only peer dependency (zero runtime deps), shipped tree-shakeable so you only pay for what you import, total bundle under 10KB. TypeScript-first with full types out of the box, 100% test coverage (Jest), and SSR-compatible (works under Next.js, Remix, etc.). Published to npm. The design philosophy is intentionally minimal — each component is a thin, well-typed wrapper whose value is readability and consistency, not features.

Tech Stack

React (peer), TypeScript, Jest (100% coverage), tree-shakeable ESM build, npm distribution.

Smart Architectural Decisions

• Readability as the product. The library doesn't add capability you couldn't write yourself — it makes intent obvious (<Show when> vs a ternary). Choosing clarity as the value proposition is a mature, opinionated API decision.
• Zero deps + ≤10KB + tree-shakeable means it's safe to adopt in any project without bundle guilt.
• SSR-compatible + 100% test coverage signal it's built to be depended on, not just published.
• Dual when/if aliasing and breakpoint-aware <Hidden on=> show attention to ergonomics and real-world usage.
• Dogfooded across the author's own apps (Watchdog, WordShot, BuffByte all import it), proving it in production.

Impacts

A published, tree-shakeable npm library that cleans up conditional/iterative JSX with 100% test coverage and a <10KB footprint — and is reused as a foundation across the author's own production apps.
