Vercel Edge Runtime instrumentation

Edge runtime instrumentation is identical for both Page Router and App Router.

• Create a file to export your EdgeHighlight wrapper function:

// utils/edge-highlight.config.ts:
import { CONSTANTS } from '../../constants'
import { EdgeHighlight } from '@highlight-run/next/server'

export const withEdgeHighlight = EdgeHighlight({
	projectID: CONSTANTS.NEXT_PUBLIC_HIGHLIGHT_PROJECT_ID,
})

• Wrap your edge function with withEdgeHighlight

Page Router

// pages/api/edge-page-router-test.ts
import { NextRequest } from 'next/server'
import { withEdgeHighlight } from '../../utils/edge-highlight.config.ts'

export default withEdgeHighlight(async function GET(request: NextRequest) {
	console.info('Here: pages/api/edge-page-router-test', request.url)

	if (request.url.includes('error')) {
		throw new Error('Error: pages/api/edge-page-router-test (Edge Runtime)')
	} else {
		return new Response('Success: pages/api/edge-page-router-test')
	}
})

export const runtime = 'edge'

App Router

// pages/api/edge-page-router-test.ts
import { NextRequest } from 'next/server'
import { withEdgeHighlight } from '../../utils/edge-highlight.config'

export default withEdgeHighlight(async function GET(request: NextRequest) {
	console.info('Here: pages/api/edge-page-router-test', request.url)

	if (request.url.includes('error')) {
		throw new Error('Error: pages/api/edge-page-router-test (Edge Runtime)')
	} else {
		return new Response('Success: pages/api/edge-page-router-test')
	}
})

export const runtime = 'edge'

Validation
