1. 1

   Install the package

   Required

   Install the PostHog Node.js library using your package manager:

   npm

   bashCopy

   npm install posthog-node

   yarn

   bashCopy

   yarn add posthog-node

   pnpm

   bashCopy

   pnpm add posthog-node

   bun

   bashCopy

2. 2

   Initialize PostHog

   Required

   Initialize the PostHog client with your project token:

   Node.js

   javascriptCopy

   import { PostHog } from 'posthog-node'
   
   const client = new PostHog(
       '<ph_project_token>',
       {
           host: 'https://us.i.posthog.com'
       }
   )

3. 3

   Send an event

   Recommended

   Once installed, you can manually send events to test your integration:

   Node.js

   javascriptCopy

   client.capture({
       distinctId: 'distinct_id_of_the_user',
       event: 'event_name',
       properties: {
           property1: 'value',
           property2: 'value',
       },
   })

4. 4

   Exception handling example

   Required

   Hono uses app.onError (opens in a new tab) to handle uncaught exceptions. You can take advantage of this for error tracking.

   Remember to export your project token (opens in a new tab) as an environment variable.

   index.ts

   typescriptCopy

   import
   
   
   
   
   
   
   
   
   
   
   
   
   

5. Verify error tracking

   Recommended

   Confirm events are being sent to PostHog

   Before proceeding, let’s make sure exception events are being captured and sent to PostHog. You should see events appear in the activity feed.

   

   Check for exceptions in PostHog (opens in a new tab)

6. 5

   Upload source maps

   Required

   Great, you’re capturing exceptions! If you serve minified bundles, the next step is to upload source maps to generate accurate stack traces.

   Let’s continue to the next section.
