Usage

By default, this plugin only generates output when run in production mode. To test your tracking code, run gatsby build && gatsby serve.

Options

Option	Explanation	Default
trackingUrl	Your Fathom custom domain (optional)	cdn.usefathom.com
siteId	Fathom site ID
honorDnt	Honor do not track	false
ignoreCanonical	Ignore canonical and use current URL	false
includedDomains	Only include provided domains in tracking	[]
excludedDomains	Track every domain, except the ones provided	[]

For more information on each option check https://usefathom.com/support/tracking-advanced.

Example

// gatsby-config.js
module.exports = {
  plugins: [
    {
      resolve: 'gatsby-plugin-fathom',
      options: {
        // Your custom domain, defaults to `cdn.usefathom.com`
        trackingUrl: 'your-fathom-instance.com',
        // Unique site id
        siteId: 'FATHOM_SITE_ID'
      }
    }
  ]
}

Example using environment variables

You may want to use different site ids across different deployments. This is best achieved by defining config in environment variables. The value will be read on build-time, e.g. during CI.

# .env.production
FATHOM_SITE_ID=ABCDEF

// gatsby-config.js
require('dotenv').config({
  path: `.env.${process.env.NODE_ENV}`
})

module.exports = {
  plugins: [
    {
      resolve: 'gatsby-plugin-fathom',
      options: {
        siteId: process.env.FATHOM_SITE_ID
      }
    }
  ]
}

Goal Tracking

You can import a hook for tracking goals in any component like so:

import { useGoal } from 'gatsby-plugin-fathom'

export default function Foo() {
  // can pass true as the 2nd param in order to console log the tracked goal's ID
  // useful for debugging in development
  const handleGoal = useGoal('GOAL-ID')

  return <button onClick={handleGoal}>Click me</button>
}

The function returned by useGoal also excepts a value to be sent with the id. If not set it defaults to 0.

import { useGoal } from 'gatsby-plugin-fathom'

export default function Foo() {
  const handleGoal = useGoal('GOAL-ID')

  return <button onClick={() => handleGoal(100)}>Buy</button>
}
