Honeycomb

The Honeycomb Pages Plugin automatically sends traces to Honeycomb for analysis and observability.

Installation

npm

npm i @cloudflare/pages-plugin-honeycomb

yarn

yarn add @cloudflare/pages-plugin-honeycomb

pnpm

pnpm add @cloudflare/pages-plugin-honeycomb

Usage

The following usage example uses environment variables you will need to set in your Pages project settings.

import honeycombPlugin from "@cloudflare/pages-plugin-honeycomb";

export const onRequest: PagesFunction<{
  HONEYCOMB_API_KEY: string;
  HONEYCOMB_DATASET: string;
}> = (context) => {
  return honeycombPlugin({
    apiKey: context.env.HONEYCOMB_API_KEY,
    dataset: context.env.HONEYCOMB_DATASET,
  })(context);
};

Alternatively, you can hard-code (not advisable for API key) your settings the following way:

import honeycombPlugin from "@cloudflare/pages-plugin-honeycomb";

export const onRequest = honeycombPlugin({
  apiKey: "YOUR_HONEYCOMB_API_KEY",
  dataset: "YOUR_HONEYCOMB_DATASET_NAME",
});

This Plugin is based on the @cloudflare/workers-honeycomb-logger and accepts the same configuration options ↗.

Ensure that you enable the option to Automatically unpack nested JSON and set the Maximum unpacking depth to 5 in your Honeycomb dataset settings.

Additional context

data.honeycomb.tracer has two methods for attaching additional information about a given trace:

• data.honeycomb.tracer.log which takes a single argument, a String.
• data.honeycomb.tracer.addData which takes a single argument, an object of arbitrary data.

More information about these methods can be seen on @cloudflare/workers-honeycomb-logger's documentation ↗.

For example, if you wanted to use the addData method to attach user information:

import type { PluginData } from "@cloudflare/pages-plugin-honeycomb";

export const onRequest: PagesFunction<unknown, any, PluginData> = async ({
  data,
  next,
  request,
}) => {
  // Authenticate the user from the request and extract user's email address
  const email = await getEmailFromRequest(request);

  data.honeycomb.tracer.addData({ email });

  return next();
};
