# TypeScript Best Practices
## When to Use
Use this skill when:
- Writing new TypeScript code
- Reviewing TypeScript pull requests
- Refactoring JavaScript to TypeScript
## Triggers
Activated when editing `.ts` or `.tsx` files in the project.
## Rules
### Always
- Always use `const` for variables that won't be reassigned
- Always use explicit return types on exported functions
- Always prefer `interface` over `type` for object shapes
### Never
- Never use `any` — use `unknown` instead
- Never use `var` — use `const` or `let`
- Never ignore TypeScript errors with `@ts-ignore`
## Examples
```typescript
// Good: explicit return type
export function calculateTotal(items: Item[]): number {
return items.reduce((sum, item) => sum + item.price, 0);
}
```
```typescript
// Good: discriminated union
type Result<T> =
| { success: true; data: T }
| { success: false; error: Error };
```
## Boundaries
- Do not modify `tsconfig.json` without explicit permission
- Do not add new dependencies without checking existing utilities
- Focus only on TypeScript patterns, not runtime behavior
