Detail Objek Error

Deserve menyediakan penanganan error untuk route execution errors, validation errors, not found errors, static file errors, dan custom error responses.

Penanganan Error Dasar

Tangani error dengan method router.catch():

import { Router } from '@neabyte/deserve'

const router = new Router({ routesDir: './routes' })

router.catch((ctx, error) => {
  return ctx.send.json({
    error: 'Something went wrong',
    statusCode: error.statusCode,
    path: error.path,
    method: error.method
  }, { status: error.statusCode })
})

router.serve(8000)

Struktur Objek Error

Error handler menerima objek context dan objek error:

router.catch((ctx, error) => {
  // error.statusCode - HTTP status code (404, 500, dll.)
  // error.path - Request path
  // error.method - HTTP method
  // error.error - Objek Error (jika tersedia)
  return ctx.send.json({
    error: error.error?.message || 'An error occurred',
    status: error.statusCode,
    path: error.path,
    method: error.method
  }, { status: error.statusCode })
})

Skenario Error Umum

404 - Route Tidak Ditemukan

router.catch((ctx, error) => {
  if (error.statusCode === 404) {
    return ctx.send.json({
      error: 'Route not found', path: error.path
    }, { status: 404 })
  }
  return null // Gunakan default error handling
})

500 - Server Errors

router.catch((ctx, error) => {
  if (error.statusCode === 500) {
    console.error('Server error:', error.error)
    return ctx.send.json({ error: 'Internal server error' }, { status: 500 })
  }
  return null
})

Penanganan Error di Route Handler

Tangani error di route handler individual:

export async function POST(ctx: Context): Promise<Response> {
  try {
    const data = await ctx.body()
    // Process data...
    return ctx.send.json({ success: true })
  } catch (error) {
    return ctx.send.json(
      { error: 'Failed to process request' },
      { status: 500 }
    )
  }
}

Validation Errors

Kembalikan status code yang sesuai untuk validation errors:

export async function POST(ctx: Context): Promise<Response> {
  const data = await ctx.body()
  if (!data.email) {
    return ctx.send.json(
      { error: 'Email is required' },
      { status: 400 }
    )
  }
  // Process valid data...
  return ctx.send.json({ success: true })
}
