Type Automator-TypeScript Interface Automation

Example

// Given a JSON object from an API: { 'id': 1, 'name': 'John Doe', 'email': null } interface User { id: number; name: string; email?: string; // Note the use of '?' for nullable field }

Scenario

This functionality is pivotal when developers are dealing with RESTful APIs where JSON data needs to be strongly typed in a TypeScript application. It ensures that the data conforms to expected types, enhancing code reliability and developer productivity by providing compile-time type checking.

Example

// API returns: { 'status': 'active', 'statuses': ['active', 'inactive', 'pending'] } export enum UserStatus { 'active', 'inactive', 'pending' } export type UserStatusType = keyof typeof UserStatus;

Scenario

Useful for APIs that define a limited set of allowable values for certain fields, Type Automator can automatically generate TypeScript enums and associated types from these values. This is especially helpful in maintaining consistency with backend data validations and frontend type usage.

Example

// API returns a complex structure: { 'details': { 'firstName': 'John', 'lastName': 'Doe' }, 'isActive': 'true' } interface UserDetails { firstName: string; lastName: string; } interface User { details: UserDetails; isActive: boolean; // Automatic type transformation from string to boolean }

Scenario

When API data does not directly match the TypeScript data structures, Type Automator can transform data types to better fit TypeScript standards, such as converting strings to booleans or numbers to enums. This is critical in applications where data integrity and type correctness are paramount.
