typescript

Strict TypeScript baseline: no any, narrowing on unknown, exhaustive switches, no enums.

npx rulepack add typescript

What it covers

• A strict tsconfig baseline kept on: strict, noUncheckedIndexedAccess, noImplicitOverride, noFallthroughCasesInSwitch, noUnusedLocals / noUnusedParameters, verbatimModuleSyntax
• Type discipline: never any (type as unknown and narrow), union literals over enums, satisfies for conformance, as only as a last resort with a comment
• Patterns: discriminated unions for state machines, Result<T, E>-style returns over throwing for expected failures, branded types for IDs
• Module shape: types exported alongside their values, import type { … } for type-only imports, explicit export surface instead of catch-all barrels
