Apa itu Next.js?
Next.js merupakan sebuah React framework yang dibentuk buat mengatasi kasus client-side rendering yang dimiliki React. Sebuah halaman website yang dibentuk memakai React ‘terasa ringan’ lantaran tampilan website sangat interaktif.
Selain itu, ketika data berubah, React menggunakan efisien akan mengupdate bagian menurut halaman website yang memang perlu diupdate tanpa perlu reload satu halaman penuh.
Untuk menerima itu seluruh, client wajib load seluruh file JavaScript sebelum konten halaman ditampilkan. apabila file JS relatif akbar maka ketika yang diperlukan buat load pertama kali pula sebagai lebih lama.
Masalah lain menurut client-side rendering merupakan SEO, terdapat kemungkinan web crawler berusaha mengindex halaman yang belum terselesaikan dirender sepenuhnya (lantaran ketika load yang lama). Dan menduga web tadi blank.
Kedua kasus diatas bisa diselesaikan menggunakan teknik pre-rendering. Yaitu halaman HTML dan file JavaScript pada generate sebelum dikirim ke client.
Ada dua bentuk pre-rendering yaitu Server Side Rendering (SSR) dan Static Site Generator (SSG).
Server Side Rendering(SSR)
Sesuai namanya proses render terjadi pada server dan bukan pada client, setiap request ke server akan direspon menggunakan sebuah halaman HTML.
Static Site Generator (SSG)
Setiap request ke server akan direspon menggunakan halaman HTML yang telah terselesaikan digenerate dalam ketika proses build. Teknik cache memakai CDN bisa diterapkan buat mempersingkat ketika akses.
Next.js bisa melakukan keduanya.
Features
Selain pre-rendering, Next.js pula mempunyai beberapa fitur buat memudahkan kita pada menciptakan pelaksanaan React:
Page-based routing system, alamat menurut halaman merupakan nama file menurut halaman tadi
Code splitting, code JavaScript dipecah sebagai chunk supaya ketika loading halaman sebagai lebih singkat
Client-side routing, routing pula sanggup dilakukan pada sisi client
Fast refresh support, seperti menggunakan hot reloading
Built-In CSS, support CSS Module, SAAS dan CSS-in-JS
Automatic Image Optimization, tersedia dalam Next.js versi 10 keatas
API Routes, menciptakan API tanpa library
JSON — singkatan dari “JavaScript Object Notation“— adalah sebuah format untuk berbagi data. JSON menggunakan ekstensi .json. Karena sangat mudah dibaca dan ringan, JSON memberikan alternatif lebih baik dari XML dan membutuhkan formatting yang tidak banyak.
Pertama kita buat folder dengan nama kategori selanjutnya buat file dengan nama promo.js untuk halaman kategori semua produk..
import Head from 'next/head'
import Link from 'next/link'
const Kategori = () => {
return (
