martmull 77d1e8ced6 feat(app-dev): sync error hints, flatEntity labels, dev-mode summary UI, and docs (#21252)
Split out of #21240 — all remaining app-dev improvements. Stacked on
#21251 (review/merge that first).

- Actionable recovery hints on failed syncs; unified diff renderer;
`--dry-run` guard.
- Return `flatEntity` on update/delete sync actions and unify the diff
label.
- Summarize the dev-mode entity list unless `--verbose`.
- Docs: syncing & recovery guide + dry-run + open-an-issue prompt.
- Live execution mode for synced logic functions; clearer manifest
warnings.

Twenty SDK

NPM version License Join the community on Discord

A CLI and SDK to develop, build, and publish applications that extend Twenty CRM.

Quick start

The recommended way to start is with create-twenty-app:

npx create-twenty-app@latest my-twenty-app
cd my-twenty-app
yarn twenty dev

Documentation

Full documentation is available at docs.twenty.com/developers/extend/apps:

  • Getting Started — scaffolding, local server, authentication, dev mode
  • Building Apps — entity definitions, API clients, testing, CLI reference
  • Publishing — deploy, npm publish, marketplace

Manual installation

If you are adding twenty-sdk to an existing project instead of using create-twenty-app:

yarn add twenty-sdk twenty-client-sdk

Then add a twenty script to your package.json:

{
  "scripts": {
    "twenty": "twenty"
  }
}

Run yarn twenty help to see all available commands.

Configuration

The CLI stores credentials per remote in ~/.twenty/config.json. Run yarn twenty remote:add to configure a remote, or yarn twenty remote:list to see existing ones.

Troubleshooting

  • Auth errors: run yarn twenty remote:add to re-authenticate.
  • Typings out of date: restart yarn twenty dev to refresh the client and types.
  • Not seeing changes in dev: make sure dev mode is running (yarn twenty dev).
