Rollbar integration plugin for Cloudflare Pages

yarn add @hckr_/cloudflare-pages-plugin-rollbar

npm install @hckr_/cloudflare-pages-plugin-rollbar

// functions/_middleware.js
import rollbarPlugin from "@hckr_/cloudflare-pages-plugin-rollbar";

/**
 * @param {EventContext<Env>} context
 * @returns {Promise<Response>}
 */
export async function rollbar(context) {
  return rollbarPlugin({ token: context.env.ROLLBAR_TOKEN })(context);
}

export const onRequest = [rollbar];

The Plugin takes an object with two properties: the Rollbar Project Access token with post_server_item scope and optional custom for adding custom properties into logged payload.

This plugin catches unhandled exceptions and logs them into Rollbar. It gathers request data and Cloudflare metadata with exception details.

You can access Rollbar logger instance via the context.data.rollbar property. There are debug, info, warn and error methods for corresponding levels. First three take message and attributes as parameters. error takes exception and descrition.

interface Rollbar {
    debug(message: string, attributes: Record<string, any>): Promise;
    info(message: string, attributes: Record<string, any>): Promise;
    warn(message: string, attributes: Record<string, any>): Promise;
    error(exception: Error, description: string): Promise;
}
