Claude Code के साथ Accelerating Next.js Full-Stack Development

Next.js × Claude Code सेフルスタックdevelopment

Next.jsのApp Routerは、フロントエンドとバックエンドをintegration的にdevelopmentできるframework है।Claude Code के साथ combineる बातで、page、APIroute、databaseintegration तकを一気にbuild किया जा सकता है。

Projectの初期setup

> Next.js 14 + TypeScript + Tailwind CSS + Prismaの
> Projectをबनाओ。App Routerを使用。
> निम्नलिखितの構成で：
> - src/app: page・layout
> - src/components: 共通component
> - src/lib: utility・DB接続
> - prisma: スkeyマ・migration

Server Componentsのutilization

dataフェッチングをServer Componentsでकरनाpattern generateさせ है।

> ブlog記事listpageをServer Componentでबनाओ。
> Prisma सेdatafetch。pageネーションsupport。

// src/app/posts/page.tsx
import { prisma } from "@/lib/prisma";
import { PostCard } from "@/components/PostCard";
import { Pagination } from "@/components/Pagination";

interface Props {
  searchParams: Promise<{ page?: string }>;
}

export default async function PostsPage({ searchParams }: Props) {
  const { page: pageParam } = await searchParams;
  const page = Number(pageParam) || 1;
  const perPage = 12;

  const [posts, total] = await Promise.all([
    prisma.post.findMany({
      take: perPage,
      skip: (page - 1) * perPage,
      orderBy: { createdAt: "desc" },
      include: { author: { select: { name: true, avatar: true } } },
    }),
    prisma.post.count(),
  ]);

  return (
    <main className="container mx-auto px-4 py-8">
      <h1 className="mb-8 text-3xl font-bold">記事list</h1>
      <div className="grid gap-6 md:grid-cols-2 lg:grid-cols-3">
        {posts.map((post) => (
          <PostCard key={post.id} post={post} />
        ))}
      </div>
      <Pagination
        currentPage={page}
        totalPages={Math.ceil(total / perPage)}
        basePath="/posts"
      />
    </main>
  );
}

export const metadata = {
  title: "記事list",
  description: "सभीの記事 displayします",
};

Server Actionsのutilization

formprocessingをServer Actionsでimplement करते हैं。

> 記事createformをServer Actionsでimplement करो。
> validationはzod、error handlingも含めて。

// src/app/posts/new/actions.ts
"use server";

import { prisma } from "@/lib/prisma";
import { redirect } from "next/navigation";
import { z } from "zod";

const CreatePostSchema = z.object({
  title: z.string().min(1, "タイトルは必須です").max(200),
  content: z.string().min(10, "本文は10文字以ऊपरज़रूरीです"),
  published: z.boolean().default(false),
});

export type FormState = {
  errors?: Record<string, string[]>;
  message?: string;
};

export async function createPost(
  prevState: FormState,
  formData: FormData
): Promise<FormState> {
  const parsed = CreatePostSchema.safeParse({
    title: formData.get("title"),
    content: formData.get("content"),
    published: formData.get("published") === "on",
  });

  if (!parsed.success) {
    return { errors: parsed.error.flatten().fieldErrors };
  }

  await prisma.post.create({
    data: { ...parsed.data, authorId: "current-user-id" },
  });

  redirect("/posts");
}

API Routeのcreate

बाहर部integration用のAPI Routeも同時にcreateでき है।

> /api/posts のRoute Handlerをबनाओ。
> GET（list・search・pageネーション）と POST（create）。
> authenticationcheckも含めて。

// src/app/api/posts/route.ts
import { NextRequest, NextResponse } from "next/server";
import { prisma } from "@/lib/prisma";
import { auth } from "@/lib/auth";

export async function GET(request: NextRequest) {
  const { searchParams } = request.nextUrl;
  const page = Number(searchParams.get("page")) || 1;
  const q = searchParams.get("q") || "";
  const limit = 20;

  const where = q
    ? { title: { contains: q, mode: "insensitive" as const } }
    : {};

  const [posts, total] = await Promise.all([
    prisma.post.findMany({
      where,
      take: limit,
      skip: (page - 1) * limit,
      orderBy: { createdAt: "desc" },
    }),
    prisma.post.count({ where }),
  ]);

  return NextResponse.json({
    data: posts,
    meta: { page, limit, total },
  });
}

export async function POST(request: NextRequest) {
  const session = await auth();
  if (!session) {
    return NextResponse.json({ error: "Unauthorized" }, { status: 401 });
  }

  const body = await request.json();
  const post = await prisma.post.create({
    data: { ...body, authorId: session.user.id },
  });

  return NextResponse.json({ data: post }, { status: 201 });
}

middlewareのsettings

authenticationroutingをmiddlewareで制御し है।

> authenticationがज़रूरीなrouteをmiddlewareで保護して。
> /dashboard, /posts/new, /api/posts(POST) はauthentication必須。
