## Summary
Lets a Twenty application add **view fields (columns) to an existing
view it does not own** — including standard views like the People index
view — without redeclaring/owning that view. This mirrors the existing,
working pattern by which an app adds a custom field to a standard object
via `defineField` + `objectUniversalIdentifier`.
The asymmetry being removed was purely in the manifest schema:
`ViewFieldManifest` only existed *nested* inside
`ViewManifest.fields[]`, so adding a view field forced declaring a
`ViewManifest` — which the sync treats as a view the app creates and
owns, and rejects when the UID is a standard view's. Validation,
persistence, the FK aggregator machinery, and uninstall cleanup were
already generic and cross-app-safe, so no engine changes were needed.
### Changes
- **twenty-shared:** new top-level `StandaloneViewFieldManifest`
(`ViewFieldManifest & { viewUniversalIdentifier }`),
`Manifest.viewFields`, and a `SyncableEntity.ViewField` member.
- **twenty-sdk:** `defineViewField` (validates `universalIdentifier` +
`viewUniversalIdentifier` + `fieldMetadataUniversalIdentifier`), CLI
manifest assembly of a top-level `viewFields` list, and `dev:add
viewField` scaffolding.
- **twenty-server:** one top-level loop over `manifest.viewFields` that
reuses the existing `fromViewFieldManifestToUniversalFlatViewField`
converter (already parameterized by `viewUniversalIdentifier`). No
validator/persistence/aggregator changes.
### Notes for maintainers
- Confirm the `Manifest.viewFields` optionality convention — implemented
as a **required** array to mirror `fields`/`views`.
- Two different apps adding a column for the same field to the same view
conflicts on the existing unique `(fieldMetadataId, viewId)` partial
index; the existing `flat-view-field-validator` duplicate check surfaces
this as a structured validation error.
- `dev:add viewField` scaffolding is included (was optional in the
plan).
## Test Plan
- [x] `twenty-shared` typecheck
- [x] `twenty-sdk` 364 unit tests + `buildManifest` assembly test
(rich-app fixture) + typecheck + prettier
- [x] `twenty-server` typecheck + `lint:diff-with-main`
- [x] **Server integration suite**
`successful-manifest-update-view-field.integration-spec.ts` (4/4):
- standalone view field attaches to the standard `allPeople` view
without recreating it (sync succeeds, no
`INVALID_VIEW_DATA`/`ENTITY_ALREADY_EXISTS`)
- uninstall removes the contributed column while the standard view + its
columns remain intact
- duplicate `(view, field)` rejected with `METADATA_VALIDATION_FAILED`
- unknown target view rejected
- [x] Sibling `successful-manifest-update-field.integration-spec.ts`
still green (no harness regression)

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
