# Hello world A minimal hello-world application built with an alpha version of the twenty-cli. ⚠️ Since this project uses an early alpha release, expect breaking changes and evolving features. This example will gradually gain complexity and capabilities as the twenty-cli matures with future updates. ## Requirements - twenty-cli `npm install -g twenty-cli` - an `apiKey`. Go to `/settings/api-webhooks` to generate one ## Install to your Twenty workspace - replace `` with your apiKey ```bash twenty auth login twenty app sync ``` ## What it does - creates a new object `postCard` with a `name` field - creates a serverless function `create-new-post-card` - two triggers on `create-new-post-card`: - one route trigger on `GET` `/post-card/create?recipient=RecipientName` - one databaseEvent trigger on `people.created` events ## Development Run dev mode and see application updates on your workspace instantly ```bash twenty app dev ```
