Charles Bochet ad1a4ecca0 Add isUnique support for application-defined fields (#19609)
## Summary

- Adds `isUnique?: boolean` to `RegularFieldManifest` in
`twenty-shared`, allowing SDK applications to declare unique constraints
on fields
- Updates the manifest-to-flat-field converter to read `isUnique` from
the manifest instead of hardcoding `false`
- Generates corresponding unique index metadata in
`computeApplicationManifestAllUniversalFlatEntityMaps` when a field has
`isUnique: true`, matching the behavior of the `CreateFieldInput` path
- Adds SDK-side validation rejecting `isUnique` on RELATION,
MORPH_RELATION, and FILES field types
- Adds integration test verifying manifest sync creates a unique index
for `isUnique` fields
- Adds SDK unit tests for `isUnique` validation on unsupported field
types

## Test plan

- [x] SDK unit tests: `defineField` accepts `isUnique: true` on TEXT,
rejects on RELATION and FILES
- [ ] Integration test: manifest sync with `isUnique: true` creates the
unique index in DB
- [ ] Verify `isUnique` defaults to `false` when not specified (backward
compatible)
- [ ] Verify standalone manifest fields (not nested in objects) also
generate unique indexes correctly

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-app
cd my-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  • Typings out of date: restart yarn twenty dev to refresh the client and types.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).
