مولد TypeScript من JSON المجاني عبر الإنترنت
توقف عن كتابة الواجهات يدويًا لاستجابات API. الصق JSON واحصل على واجهات TypeScript مع فصل الكائنات المتداخلة إلى أنواع منفصلة واستنتاج أشكال عناصر المصفوفة تلقائيًا.
قم بتسمية واجهتك الجذرية، انسخ المخرجات إلى مشروعك، واستخدمها مع fetch أو عميل HTTP الخاص بك للحصول على سلامة النوع الكاملة. كل شيء يعمل من جانب العميل في متصفحك.
Frequently Asked Questions
What TypeScript types are generated?
Primitive JSON values map to string, number, boolean, and null. Arrays become Type[] with the element type inferred from the first item. Objects become interfaces with named properties. Nested objects generate separate interface definitions.
How are optional fields handled?
Properties present in the sample JSON are included as required fields. If you need optional fields, add them to your sample JSON with null values, or manually add ? to the generated interface properties.
Can I name the root interface?
Yes. Set a custom root interface name before generating. Nested interfaces are named automatically based on property names (e.g., Address for an address object).
Does this handle union types?
The generator infers types from a single sample. If a field can be string or number, provide samples that include both variants, or manually adjust the generated type to a union (string | number).
Is the output compatible with strict TypeScript?
Yes. Generated interfaces use standard TypeScript syntax compatible with strict mode. Review nullable fields - JSON null maps to null in the type, not undefined. Adjust to field?: Type | null if needed.
