dependencies Status devDependencies Status

Frontend library to interact with Plausible Analytics.


  • Less than 1kb!
  • Same features as the official script, but as an NPM module
  • Automatically track page views in your SPA apps
  • Track goals and custom events
  • Provide manual values that will be bound to the event
  • Full typescript support


To install, simply run:

npm install plausible-tracker
yarn add plausible-tracker


To begin tracking events, you must initialize the tracker:

import Plausible from 'plausible-tracker'
const plausible = Plausible({
  domain: 'my-app.com'

Plausible() accepts some options that you may want to provide:

Option Type Description Default
domain string Your site's domain, as declared by you in Plausible's settings location.hostname
hashMode bool Enables tracking based on URL hash changes. false
trackLocalhost bool Enables tracking on localhost. false
apiHost string Plausible's API host to use. Change this if you are self-hosting. 'https://plausible.io'

The object returned from Plausible() contains the functions that you'll use to track your events. These functions are:

For the complete documentation on these functions and their parameters, check out the reference documentation.

Tracking page views

To track a page view, use the trackPageview function provided

import Plausible from 'plausible-tracker'
const { trackPageview } = Plausible()
// Track a page view

You may also override the values you provided when initializing the tracker by passing a similar object as the first parameter.

This object takes the same options as the initialization one, plus the following:

Option Type Description Default
url string Current page's URL. location.href
referrer string or null Referrer's address document.referrer
deviceWidth number User's device width for device tracking. window.innerWidth
import Plausible from 'plausible-tracker'
const { trackPageview } = Plausible({
  // Track localhost by default
  trackLocalhost: true,
// Override it on this call and also set a custom url
  trackLocalhost: false,
  url: "https://my-app.com/my-url"

The second parameter is an object with some options similar to the ones provided by the official Plausible script.

import Plausible from 'plausible-tracker'
const { trackPageview } = Plausible()
// And override it on this call
trackPageview({}, { callback: () => console.log("Done!") })

Automatically tracking page views

If your app is a SPA that uses JS-based routing, you'll need to use browser events to manually track page views. A built-in function enableAutoPageviews enables automatic tracking for you so you don't need to write custom logic.

import Plausible from 'plausible-tracker'
const { enableAutoPageviews } = Plausible()
// This tracks the current page view and all future ones as well

If your app uses URL hashes to represent pages, set hashMode to true:

import Plausible from 'plausible-tracker'
const { enableAutoPageviews } = Plausible({
  hashMode: true
// Hash changes will also trigger page views

The way it works is by overriding history.pushState and attaching event listeners to popstate and hashchange (only if you set hashMode to true). If your frontend framework uses other methods to manage navigation, you might want to write your own logic using trackPageview to manually trigger page views.

Cleaning up the event listeners

When you call enableAutoPageviews(), it adds some event listeners and overrides history.pushState. To remove them and restore history.pushState, call the cleanup function returned by enableAutoPageviews():

import Plausible from 'plausible-tracker'
const { enableAutoPageviews } = Plausible()
const cleanup = enableAutoPageviews()
// ...
// Remove event listeners and restore history.pushState

Tracking custom events and goals

To track goals, all you need to do is call trackEvent and give it the name of the goal/event as the first parameter:

import Plausible from 'plausible-tracker'
const { trackEvent } = Plausible()
// Tracks the 'signup' goal

Custom props can be provided using the second parameter:

// Tracks the 'Download' goal and provides a 'method' property.
trackEvent('signup', { props: { method: 'HTTP' } })

As with trackPageview, you may also provide override values but now through the third parameter:

import Plausible from 'plausible-tracker'
const { trackEvent } = Plausible({
  trackLocalhost: false,
// Tracks the 'signup' goal with a callback, props and a different referrer.
    callback: () => console.log('done'),
    props: {
      variation: 'button A'
  { trackLocalhost: true }

Outbound link click tracking

You can also track all clicks to outbound links using enableAutoOutboundTracking.

For details on how to setup the tracking, visit the docs.

This function adds a click event listener to all a tags on the page and reports them to Plausible. It also creates a MutationObserver that efficiently tracks node mutations, so dynamically-added links are also tracked.

import Plausible from 'plausible-tracker'
const { enableAutoOutboundTracking } = Plausible()
// Track all existing and future outbound links

Cleaning up the event listeners

When you call enableAutoOutboundTracking(), it adds some event listeners and initializes a MutationObserver. To remove them, call the cleanup function returned by enableAutoOutboundTracking():

import Plausible from 'plausible-tracker'
const { enableAutoOutboundTracking } = Plausible()
const cleanup = enableAutoOutboundTracking()
// ...
// Remove event listeners and disconnect the MutationObserver
