## Summary

Adds typed application variables with optional select **options**. This
is the other half of #22059, split out from the custom-settings-tab
removal.

## Changes

- **Shared types**: `ApplicationVariable` / `ServerVariables` gain an
optional `type` (a `FieldMetadataType` subset — `TEXT`, `BOOLEAN`,
`NUMBER`, `DATE`, `SELECT`, `MULTI_SELECT`, `RAW_JSON`, `RICH_TEXT`,
`ARRAY`, …) and select `options`. New
`serializeApplicationVariableValue` /
`deserializeApplicationVariableValue` helpers convert typed values
to/from the encrypted string storage.
- **Server**: `type`/`options` columns on `applicationVariable` and
`applicationRegistrationVariable` (entities + DTOs), a fast `2-17`
instance command, manifest processing via the serialization helpers, and
a `QueryDeepPartialEntity` cast where the manifest JSON column is
persisted.
- **Frontend**: a polymorphic `SettingsApplicationVariableInput` that
renders the native `Form*` field component for each type (boolean,
number, date/date-time, select, multi-select, array, raw JSON, rich
text, text); fragment/query updates to fetch `type`/`options`.
- **SDK**: `defineApplication` validates that `SELECT`/`MULTI_SELECT`
variables declare non-empty `options` at build time (since `options` is
kept structurally optional for TypeORM/SDK compatibility).

Variables default to `TEXT` when no type is given, so existing manifests
are unaffected.

## Notes

The generated GraphQL artifacts (`type`/`options` on the variable types)
are regenerated by codegen; that change accompanies this PR.

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

Guides in this repository:

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).
