TypeScript Best Practices for Frontend Development

TypeScript Best Practices for Frontend Development

TypeScript has become the standard for modern frontend development. Here are the best practices you should follow.

Type Safety

Strict Mode

Always enable strict mode in tsconfig.json. It catches many errors at compile time.

Avoid 'any'

Minimize the use of 'any' type. Use 'unknown' or proper types instead.

Type Definitions

Interface vs Type

Use interfaces for object shapes that might be extended. Use types for unions, intersections, and computed types.

Utility Types

Leverage TypeScript utility types like Partial, Pick, Omit, and Record to create new types from existing ones.

Code Organization

Type Organization

Keep types close to where they're used, or create a types directory for shared types.

Conclusion

TypeScript is a powerful tool when used correctly. These practices will help you write more maintainable and error-free code.
