const express = require('express');
const router = express.Router()

const fetch = require('node-fetch');
router.delete('/nadmin/kategoriler/:id', async (req, res) => {
  try {
    console.log("test çalışıyor mu")
    const kategoriId = req.params.id;
    await Kategori.findByIdAndDelete(kategoriId);
    res.json({ success: true });
    console.log("burada")
  } catch (err) {
    console.log(err);
    res.json({ success: false });
    console.log("hata")
  }
});
module.exports = router;

const deleteCategory = async (categoryId) => {
    try {
      console.log("test çalışıyor mu ?")
      const response = await fetch(`/nadmin/kategoriler/${categoryId.toString()}`, { method: 'delete', headers: {"Content-type": "application/json"}});
      const data = await response.json();
      if (data.success) {
        console.log("silme başarılı");
      } else {
        console.log('silme başarısız')
      }
    } catch (err) {
      console.log(JSON.stringify(err))
    }
  }
