typedoc-plugin-umami-analytics

A TypeDoc plugin for integrating Umami Analytics into your documentation.

This plugin automatically inserts the Umami Analytics tracking script into the generated TypeDoc HTML pages, allowing you to track page views and events on your documentation website.

Why?

TypeDoc is a powerful tool for generating documentation from TypeScript code, but it does not include built-in analytics capabilities. If you want to track how users interact with your documentation, you typically need to integrate a third-party analytics solution.

Umami Analytics is a simple, open-source web analytics solution that provides insights into your website's traffic without compromising user privacy. It is 100% free when self-hosted and does not use cookies, making it a great choice for developers who want to track their documentation usage without the overhead of traditional analytics solutions.

Since I use both of these tools in my projects, I decided to create this plugin to make it easier for myself (and you!) to integrate Umami Analytics into TypeDoc-generated documentation.

Installation

npm install --save-dev typedoc-plugin-umami-analytics

Usage

This plugin can be used with TypeDoc either via command line argument, or programmatically via a TypeDoc config file.

Command Line

typedoc --plugin typedoc-plugin-umami-analytics

TypeDoc Config File

// typedoc.json
{
  "plugin": ["typedoc-plugin-umami-analytics"],
}

Configuration Options

You can configure the plugin by passing options in your TypeDoc config file or via command line arguments.

Required Options

In order to use this plugin, you must provide the following options:

{
  "plugin": ["typedoc-plugin-umami-analytics"],
  // Required: The URL of your Umami Analytics tracking script, e.g. "https://example.com/script.js"
  "umamiScriptURL": "https://example.com/script.js",
  // Required: The website ID for your Umami Analytics instance. You can find this in your Umami dashboard.
  "umamiWebsiteID": "your-website-id",
}

This input will result in the following HTML being added before the closing </body> tag of each generated HTML page:

<script
  defer
  src="https://example.com/script.js"
  data-website-id="your-website-id"></script>

Additional Options

You can also provide the following optional configuration options (in line with the Umami Tracker Configuration options):

{
  /**
   * The URL of the Umami Analytics host, e.g. "https://example-other.com"
   *
   * Only use this if your Umami instance is hosted on a different domain than the script URL.
   * If not specified, the script URL's domain will be used.
   */
  "umamiHostURL": "https://example-other.com",
  /**
   * Whether to automatically track page views and events.
   * Defaults to true.
   */
  "umamiAutoTrack": false,
  /**
   * A list of domains to track.
   * If specified, only these domains will be tracked.
   * If not specified, all domains where the script is loaded will be tracked.
   */
  "umamiDomains": ["example.com", "example.org"],
  /**
   * A tag to associate with the analytics data.
   * This can be used to filter or categorize the data in your Umami Analytics dashboard.
   */
  "umamiTag": "documentation",
  /**
   * Whether to exclude search parameters from the URL when tracking page views.
   * Defaults to false.
   */
  "umamiExcludeSearch": true,
  /**
   * Whether to exclude hash fragments from the URL when tracking page views.
   * Defaults to false.
   */
  "umamiExcludeHash": true,
  /**
   * Whether to respect the Do Not Track setting in the user's browser.
   * If true, no analytics data will be sent if the user has enabled Do Not Track.
   * Defaults to false.
   */
  "umamiDoNotTrack": true,
}

Type-Checking Configuration

This plugin also exposes TypeScript types for the configuration options, so you can use them in your TypeDoc config file to enable type-checking and IDE intellisense. Simply switch from a typedoc.json file to a typedoc.config.mjs file and import the types like so:

/** @type {Partial<import('typedoc').TypeDocOptions> & Partial<import('typedoc-plugin-umami-analytics').Config>} */
const config = {
  // ...other TypeDoc options
  plugin: [
    // ...other plugins,
    'typedoc-plugin-umami-analytics',
  ],
  umamiScriptURL: 'https://example.com/script.js',
  umamiWebsiteID: 'your-website-id',
};

export default config;
