# Introduction Following https://github.com/twentyhq/twenty/pull/13264, this PR introduces several `fieldMetadataEntity` typing enhancement suggestions. Mainly any nullable field metadata entity properties are now either nullable or defined. Or never if field is dynamically required or not depending on the field metadata type This enhance DevX ## Standards - field enum ( `MULTI_SELECT`, `SELECT`, `RATING` ) will never have `options` set to `NULL` in db - field `RELATION` or `MORH_RELATION` won't ever have its relation fields set to `NULL` in db - field of any type `settings`, even if possibly defined, can still be `NULL` in db - field of any type `defaultValue`, even if possibly defined, can still be `NULL` in db It coud be interesting to guard these standards by adding dedicated pg constraints on each field ## TypesScript type tests added coverage for each `settings`, `defaultValue`, and `options` depending on the current `fieldMetadata` Honestly I don' know if this typescript assertions test file is not overkill, but regarding metadata staticness it might be very interesting to have this guard ## Possible improvements - We could type as `unknown` instead of "all" on `FieldMetadataType` inferrance - We still need to deprecate remaining duplicated entities such as `Index/Field/MetadataInterface` etc not a huge refactor neither urgent

Does the world need another CRM?
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
