Node.js product analytics installation

Run either npm or yarn in terminal to add it to your project:

npm install posthog-node --save

In your app, set your project API key before making any calls.

import { PostHog } from 'posthog-node'

const client = new PostHog(
    '<ph_project_api_key>',
    { host: 'https://us.i.posthog.com' }
)

await client.shutdown() 

You can find your project API key and instance address in the project settings page in PostHog.

Note: As a rule of thumb, we do not recommend hardcoding API keys. Setting it as an environment variable is preferred.
