TypeScript Patterns | Agent Skills Atlas

About this skill

Idiomatic TypeScript patterns — strict type system, discriminated unions, generic inference, satisfies, branded types, errors as values, ESM/CJS modules with exports maps, Promise combinators and AbortController, iterators and higher-order functions, runtime selection across Node/Deno/Bun/browser/edge, and the Vite + Vitest toolchain stack. Use when the user is writing new TypeScript, reviewing TS code, refactoring, designing libraries for npm, tuning tsconfig strict mode, asks about generics/conditional types/discriminated unions/branded types/satisfies, asks about ESM/CJS dual publishing and exports maps, asks about Promise combinators/AbortController/async iterators, asks about Vite config or vite build --lib, chooses between Node/Deno/Bun/browser/edge runtimes, or wants TypeScript idioms and anti-patterns.

Original description

Idiomatic TypeScript patterns — strict type system, discriminated unions, generic inference, `satisfies`, branded types, errors as values, ESM/CJS modules with `exports` maps, Promise combinators and AbortController, iterators and higher-order functions, runtime selection across Node/Deno/Bun/browser/edge, and the Vite + Vitest toolchain stack. Use when the user is writing new TypeScript, reviewing TS code, refactoring, designing libraries for npm, tuning `tsconfig` strict mode, asks about generics/conditional types/discriminated unions/branded types/`satisfies`, asks about ESM/CJS dual publishing and `exports` maps, asks about Promise combinators/AbortController/async iterators, asks about Vite config or `vite build --lib`, chooses between Node/Deno/Bun/browser/edge runtimes, or wants TypeScript idioms and anti-patterns.
