Pagerless for Remix and React Router

Set up

npm i pagerless

export { handleError } from "pagerless/remix";

export { handleError } from "pagerless/react-router";

What it catches

• Errors in loaders, actions and rendering.
• Skips aborted requests and thrown 4xx responses.
• Reports 5xx and crashes only, never 4xx, and leaves the response, logs and error exactly as they were.
• On Node it also starts the SDK: uncaught errors and unhandled rejections, status and latency per route, failing outbound calls (Stripe, OpenAI, Supabase and others named), a heartbeat every 60 seconds and a deploy marker.
