Félix Malfait 0f8ee5714f feat(sdk): warn when local server image is behind latest (#20352)
Closes #20328.

## Summary
- Adds a CLI-side check that warns when `twenty-app-dev` is older than
the latest published Docker Hub tag.
- Reads `APP_VERSION` from the running container via `docker inspect` —
no server endpoint, no version exposed publicly. (`APP_VERSION` is
already baked in by `packages/twenty-docker/twenty/Dockerfile` for both
`twenty` and `twenty-app-dev` targets.)
- Fetches latest semver tag from Docker Hub (same API the admin panel
already uses) and caches the result for 24h in
`~/.twenty/version-check-cache.json`.
- Wired into `twenty dev`, `twenty install`, and `twenty server start`.
- Best-effort: silent on container-missing / docker / network errors,
never blocks a command.

## Why CLI-side instead of a `/healthz` extension
The original issue suggested comparing the running server version
against Docker Hub. Exposing the running version on a public endpoint
has a small but real security cost (helps attackers fingerprint
vulnerable deployments), and the version is already inside the image —
so the CLI can read it directly without ever calling the server.

## Test plan
- [x] `nx run twenty-sdk:test` — added unit tests for `parseSemver` /
`compareSemver`
- [x] `nx run twenty-sdk:typecheck`
- [x] `nx run twenty-sdk:lint`
- [ ] Manual: with an old `twenty-app-dev` image running, run `yarn
twenty install` → see warning
- [ ] Manual: with an up-to-date image, run `yarn twenty dev` → no
warning, cache file written
- [ ] Manual: no container at all → no warning, no error

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).
