Function formData

  • Form data decoder.

    typia.http.formData() is a function decoding FormData instance, with automatic type casting to the expected type. When roperty type be defined as boolean or Blob type, typia.http.formData() will cast the value to the expected type when decoding.

    By the way, as FormData is not enough to express complex data structures, typia.http.formData() function has some limitations. If target type T is not following those restrictions, compilation errors would be occured.

    1. Type T must be an object type
    2. Do not allow dynamic property
    3. Only boolean, bigint, number, string, Blob, File or their array types are allowed
    4. By the way, union type never be not allowed

    Also, typia.http.formData() function does not perform validation about the decoded value. Therefore, if you can't sure that input data is following the T type, it would better to call one of below functions intead.
