Charles BochetandGitHub c0cc0689d6 Add Client Api generation (#17961)
## Add API client generation to SDK dev mode and refactor orchestrator
into step-based pipeline

### Why

The SDK dev mode lacked typed API client generation, forcing developers
to work without auto-generated GraphQL types when building applications.
Additionally, the orchestrator was a monolithic class that mixed watcher
management, token handling, and sync logic — making it difficult to
extend with new steps like client generation.

### How

- **Refactored the orchestrator** into a step-based pipeline with
dedicated classes: `CheckServer`, `EnsureValidTokens`,
`ResolveApplication`, `BuildManifest`, `UploadFiles`,
`GenerateApiClient`, `SyncApplication`, and `StartWatchers`. Each step
has typed input/output/status, managed by a new `OrchestratorState`
class.
- **Added `GenerateApiClientOrchestratorStep`** that detects
object/field schema changes and regenerates a typed GraphQL client (via
`@genql/cli`) into `node_modules/twenty-sdk/generated` for seamless
imports.
- **Replaced `checkApplicationExist`** with `findOneApplication` on both
server resolver and SDK API service, returning the entity data instead
of a boolean.
- **Added application token pair mutations**
(`generateApplicationToken`, `renewApplicationToken`) to the API
service, with the server now returning `ApplicationTokenPairDTO`
containing both access and refresh tokens.
- **Restructured the dev UI** into `dev/ui/components/` with dedicated
panel, section, and event log components.
- **Simplified `AppDevCommand`** from ~180 lines of watcher management
down to ~40 lines that delegate entirely to the orchestrator.

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

cp .env.example .env
  • replace <SET_YOUR_TWENTY_API_KEY> and <SET_YOUR_TWENTY_API_URL> accordingly
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
