@e2e-dev/kernel

Kernel hosted browsers for e2e: web({ browser: kernel() }) runs a web target in Kernel's hosted Chromium.

Install

npm install --save-dev @e2e-dev/kernel @onkernel/sdk

Usage

import type { E2EConfig } from 'e2e';
import { web } from '@e2e-dev/web';
import { kernel } from '@e2e-dev/kernel';

export default {
  targets: [{ engine: web({ browser: kernel({ stealth: true }), viewport: null }), app: { url: 'https://staging.example.com' } }],
  workers: 4,
} satisfies E2EConfig;

KERNEL_API_KEY comes from the run's environment. kernel(options) takes Kernel's create-browser body as is (stealth, headless, timeout_seconds, profile, proxy_id, viewport, tags, ...) plus the lease scope: worker (default) is one browser per worker slot for the run, attempt a fresh browser per test attempt. Every browser is tagged with the run, target, and slot, timeout_seconds defaults to 600 so Kernel deletes a browser a dead worker never released, and each lease logs its live view URL when Kernel gives one. On a headed browser, an attempt that records video (--video, or a test's video option) gets a Kernel replay of the browser's screen as its video/replay.mp4; a headless browser and replay: false get the page screencast.
