  • Installation

PostHog supports TypeScript apps natively, without you having to compile the TypeScript yourself (although you can also do that).

To build a TypeScript app, you'll probably need some types, so read on.

Installation

To use the types in your app, you can install them as follows:

Terminal
# if using yarn
yarn add --dev @posthog/plugin-scaffold
# if using npm
npm install --save-dev @posthog/plugin-scaffold

typescript
import { PluginEvent, PluginMeta } from '@posthog/plugin-scaffold'
export function processEvent(event: PluginEvent, meta: PluginMeta) {
if (event.properties) {
event.properties['hello'] = 'world'
}
return event
}
