Access TypeScript patterns for React Native development, including strict mode configuration, API response typing, route parameters, and reusable hooks. Use topic parameter to target specific sections.

Instructions

Get TypeScript patterns for React Native. Call this when writing types or interfaces. Covers strict mode config, model types, API response types, route param typing, props interface naming, store types, generics for reusable hooks, as const, discriminated unions, and type guards. Use topic to get a specific section only.

Input Schema

Name	Required	Description	Default
`topic`	No	Get a specific section only. Available: strict-config, route-params, api-types, model-types, props-naming, store-types, generics, as-const, discriminated-unions, type-guards. Omit for full content.
`compact`	No	If true, returns rules only without code examples. Much shorter.

Implementation Reference

src/content/patterns/typescript-patterns.ts:276-277 (handler)

```
export const getTypescriptPatterns = (topic?: string, compact?: boolean): string =>
  resolvePattern(pattern, topic, compact);
```
