TypeScript best practices — covering the structural type system, generics & constraints, utility & advanced types, discriminated unions & exhaustiveness, classes & OOP (constructors, access modifiers, abstract, getters/setters, #fields), error handling with throw / try / catch and typed Error subclasses, async with AbortSignal cancellation and AsyncIterable, immutability with readonly / as const / satisfies, ESM modules, strict tsconfig, naming, and testing patterns. Includes a dedicated section on functional patterns (pure functions, hand-rolled pipe, Result<T, E>) for codebases that lean that way. Stdlib-only — no library recommendations.
npx claudepluginhub christopherdavenport/christopherdavenport-marketplace --plugin typescriptChris Davenport's personal Claude Code plugin marketplace — a collection of skills covering frontend (Lit, Jack Henry Design System), backend (Go, TypeScript, SQLite, Spanner, Pub/Sub), and financial-services knowledge (US regulations, accounting fundamentals).
Add the marketplace, then install the plugins you want:
/plugin marketplace add christopherdavenport/christopherdavenport-marketplace
/plugin install <plugin-name>@christopherdavenport
For example: /plugin install go@christopherdavenport.
