個人的な備忘録です。

環境

react: 17.0.2
react-hook-form: 7.28.0
next: 11.1.3

サンプルコード

postHandler

export const useProfileNew = () => {
  const { httpClient } = useHttpClient();

  const profileNewHandler = async (data: FormData) => {
    const requset: Request = {
      title: data.title,
      body: data.body,
    };

    const response = await httpClient.post<Response>(API_PATH);

    return response?.data;
  };

  return {
    profileNewHandler,
  };
};

putHandler

export const useProfileEdit = () => {
  const { httpClient } = useHttpClient();

  const profileEditHandler = async (data: FormData, id: string) => {
    const requset: Request = {
      title: data.title,
      body: data.body,
    };

    const response = await httpClient.put<Response>(
      `${API_PATH}/${id}`,
      request
    );

    return response?.data;
  };

  return {
    profileEditHandler,
  };
};

まとめるためのcustomHook

export const useProfileHandler = (isEdit: boolean) => {
  const { profileEditHandler } = useProfileEdit();
  const { profileNewHandler } = useProfileNew();

  const profileHandler = async (data: FormData, id: string) => {
    if (isEdit) {
      return await profileEditHandler(data, id);
    }
    return await profileNewHandler(data);
  };

  return {
    profileHandler,
  };
};

component

export const Component = () => {
  const { profileHandler } = useProfileHandler(isEdit);

  const onSubmit = async () => {
    // 使用側はどちらかを意識しなくて良い
    await profileHandler(data, id)
    reset();
  }

  // 省略

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      {/* 省略 */}
      <button type={'submit'}>
        保存する
      </button>
    </form>
  );
};
