# Honeycomb

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

## Installation

 npm  yarn  pnpm  bun 

```
npm i @cloudflare/pages-plugin-honeycomb
```

```
yarn add @cloudflare/pages-plugin-honeycomb
```

```
pnpm add @cloudflare/pages-plugin-honeycomb
```

```
bun add @cloudflare/pages-plugin-honeycomb
```

## Usage

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

TypeScript

```
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:

TypeScript

```
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 ↗](https://github.com/cloudflare/workers-honeycomb-logger#config).

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

![Follow the instructions above to toggle on Automatically unpack nested JSON and set the Maximum unpacking depth option to 5 in the Honeycomb dashboard](https://developers.cloudflare.com/_astro/honeycomb.MQ2Vf1tC_11GUXy.webp) 

### 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 ↗](https://github.com/cloudflare/workers-honeycomb-logger#adding-logs-and-other-data).

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

TypeScript

```
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();};
```
