# Introduction Improved the ci assertions to be sure the default logic function worked fully ## what's next About to introduce a s3 + lambda e2e test to cover the lambda driver too in addition of the local driver
Create Twenty App is the official scaffolding CLI for building apps on top of Twenty CRM. It sets up a ready‑to‑run project that works seamlessly with the twenty-sdk.
- Zero‑config project bootstrap
- Preconfigured scripts for auth, dev mode (watch & sync), uninstall, and function management
- Strong TypeScript support and typed client generation
Documentation
See Twenty application documentation https://docs.twenty.com/developers/extend/capabilities/apps
Prerequisites
- Node.js 24+ (recommended) and Yarn 4
- Docker (for the local Twenty dev server)
Quick start
# Scaffold a new app — the CLI will offer to start a local Twenty server
npx create-twenty-app@latest my-twenty-app
cd my-twenty-app
# The scaffolder can automatically:
# 1. Start a local Twenty server (Docker)
# 2. Open the browser to log in (tim@apple.dev / tim@apple.dev)
# 3. Authenticate your app via OAuth
# Or do it manually:
yarn twenty server start # Start local Twenty server
yarn twenty remote add http://localhost:2020 --as local # Authenticate via OAuth
# Start dev mode: watches, builds, and syncs local changes to your workspace
# (also auto-generates typed CoreApiClient — MetadataApiClient ships pre-built — both available via `twenty-client-sdk`)
yarn twenty dev
# Watch your application's function logs
yarn twenty logs
# Execute a function with a JSON payload
yarn twenty exec -n my-function -p '{"key": "value"}'
# Execute the pre-install function
yarn twenty exec --preInstall
# Execute the post-install function
yarn twenty exec --postInstall
# Build the app for distribution
yarn twenty build
# Publish the app to npm or directly to a Twenty server
yarn twenty publish
# Uninstall the application from the current workspace
yarn twenty uninstall
Scaffolding modes
Control which example files are included when creating a new app:
| Flag | Behavior |
|---|---|
-e, --exhaustive |
(default) Creates all example files |
-m, --minimal |
Creates only core files (application-config.ts and default-role.ts) |
# Default: all examples included
npx create-twenty-app@latest my-app
# Minimal: only core files
npx create-twenty-app@latest my-app -m
What gets scaffolded
Core files (always created):
application-config.ts— Application metadata configurationroles/default-role.ts— Default role for logic functionslogic-functions/pre-install.ts— Pre-install logic function (runs before app installation)logic-functions/post-install.ts— Post-install logic function (runs after app installation)- TypeScript configuration, Oxlint, package.json, .gitignore
- A prewired
twentyscript that delegates to thetwentyCLI from twenty-sdk
Example files (controlled by scaffolding mode):
objects/example-object.ts— Example custom object with a text fieldfields/example-field.ts— Example standalone field extending the example objectlogic-functions/hello-world.ts— Example logic function with HTTP triggerfront-components/hello-world.tsx— Example front componentviews/example-view.ts— Example saved view for the example objectnavigation-menu-items/example-navigation-menu-item.ts— Example sidebar navigation linkskills/example-skill.ts— Example AI agent skill definition__tests__/app-install.integration-test.ts— Integration test that builds, installs, and verifies the app (includesvitest.config.ts,tsconfig.spec.json, and a setup file)
Local server
The scaffolder can start a local Twenty dev server for you (all-in-one Docker image with PostgreSQL, Redis, server, and worker). You can also manage it manually:
yarn twenty server start # Start (pulls image if needed)
yarn twenty server status # Check if it's healthy
yarn twenty server logs # Stream logs
yarn twenty server stop # Stop (data is preserved)
yarn twenty server reset # Wipe all data and start fresh
The server is pre-seeded with a workspace and user (tim@apple.dev / tim@apple.dev).
Next steps
- Run
yarn twenty helpto see all available commands. - Use
yarn twenty remote add <url>to authenticate with your Twenty workspace via OAuth. - Explore the generated project and add your first entity with
yarn twenty add(logic functions, front components, objects, roles, views, navigation menu items, skills). - Use
yarn twenty devwhile you iterate — it watches, builds, and syncs changes to your workspace in real time. CoreApiClientis auto-generated byyarn twenty dev.MetadataApiClient(for workspace configuration and file uploads via/metadata) ships pre-built with the SDK. Both are available viaimport { CoreApiClient } from 'twenty-client-sdk/core'andimport { MetadataApiClient } from 'twenty-client-sdk/metadata'.
Build and publish your application
Once your app is ready, build and publish it using the CLI:
# Build the app (output goes to .twenty/output/)
yarn twenty build
# Build and create a tarball (.tgz) for distribution
yarn twenty build --tarball
# Publish to npm (requires npm login)
yarn twenty publish
# Publish with a dist-tag (e.g. beta, next)
yarn twenty publish --tag beta
# Deploy directly to a Twenty server (builds, uploads, and installs in one step)
yarn twenty deploy
Publish to the Twenty marketplace
You can also contribute your application to the curated marketplace:
git clone https://github.com/twentyhq/twenty.git
cd twenty
git checkout -b feature/my-awesome-app
- Copy your app folder into
twenty/packages/twenty-apps. - Commit your changes and open a pull request on https://github.com/twentyhq/twenty
Our team reviews contributions for quality, security, and reusability before merging.
Troubleshooting
- Server not starting: check Docker is running (
docker info), then tryyarn twenty server logs. - Auth not working: make sure you're logged in to Twenty in the browser first, then run
yarn twenty remote add <url>. - Types not generated: ensure
yarn twenty devis running — it auto-generates the typed client.
