Membina Laman Web Pencari Resipi menggunakan React-tutorial css-php.cn

Building Recipe Finder Website using React

pengenalan

Dalam blog ini, kami akan membina Tapak Web Pencari Resipi menggunakan React. Apl ini membolehkan pengguna mencari resipi kegemaran mereka, melihat arah aliran atau resipi baharu dan menyimpan resipi kegemaran mereka. Kami akan memanfaatkan Edamam API untuk mengambil data resipi masa nyata dan memaparkannya secara dinamik di tapak web.

Gambaran Keseluruhan Projek

Pencari Resipi membolehkan pengguna untuk:

Cari resipi mengikut nama.
Lihat sohor kini dan resipi yang baru ditambah.
Lihat maklumat terperinci tentang resipi individu.
Tambah resipi pada senarai kegemaran dan kekalkan data menggunakan localStorage.

Ciri-ciri

Fungsi Carian: Pengguna boleh mencari resipi dengan memasukkan pertanyaan.
Resipi Arah Aliran: Memaparkan resipi yang menjadi sohor kini daripada API.
Resipi Baharu: Memaparkan resipi terbaharu daripada API.
Perincian Resipi: Memaparkan maklumat terperinci tentang resipi yang dipilih.
Kegemaran: Membenarkan pengguna menambah resipi pada senarai kegemaran, yang disimpan secara setempat.

Teknologi yang Digunakan

React: Untuk membina antara muka pengguna.
Penghala Reaksi: Untuk navigasi antara halaman yang berbeza.
Edamam API: Untuk mengambil resipi.
CSS: Untuk menggayakan aplikasi.
