Fórmula e Método de Cálculo
JSON Object ➔ AST Parsing ➔ Type Inference (string, number, boolean) ➔ TS Interface
The converter recursively traverses the JSON tree. If it finds `{'age': 30}`, it infers `age: number`. Nested objects are automatically extracted into their own distinct interface definitions.
Melhores Práticas e Dicas
- Handle Optional Chaining Gracefully: If an API response sometimes omits a field, you must manually mark it as optional (e.g., `email?: string`) in the generated TypeScript interface to prevent strict compiler errors.
- Watch Out for Null Arrays: If your JSON payload includes an empty array `[]`, the converter cannot infer the type and will usually default to `any[]`. You must manually update it to the correct type (e.g., `User[]`).
- Use Type Aliases for Unions: If a field can be either a string or a number, utilize TypeScript union types (e.g., `id: string | number`) rather than downgrading the entire property to `any`.
