Route Handlers

Route Handlers allow you to create custom request handlers for a given route using Web Request and Response APIs.

Route Handlers are defined in a route.ts|js file inside the app directory.

export async function GET() {
  try {
    await client.sql`BEGIN`;
    await seedUsers();
    await seedCustomers();
    await seedInvoices();
    await seedRevenue();
    await client.sql`COMMIT`;

    return Response.json({ message: 'Database seeded successfully' });
  } catch (error) {
    await client.sql`ROLLBACK`;
    return Response.json({ error }, { status: 500 });
  }
}

localhost:3000/seedにgetリクエストが送られて、
上のgetメソッドが実行される。
