## Recoil to Jotai Migration — PR 13: Workflow, Page Layout, AI, Activities, Settings, SSE & Remaining Modules ### Summary This is the 13th PR in the [14-PR migration series](packages/twenty-front/src/modules/ui/utilities/state/jotai/MIGRATION_PLAN.md) to replace Recoil with Jotai as the state management library in `twenty-front`. This PR migrates the remaining consumer code across all modules — updating ~1,076 files with ~10k insertions/deletions. ### What changed **New Jotai infrastructure (13 new files):** - `createComponentSelectorV2` and `createComponentFamilySelectorV2` — instance-scoped derived atoms, replacing Recoil's component selectors - 6 new hooks: `useRecoilComponentSelectorValueV2`, `useRecoilComponentFamilySelectorValueV2`, `useRecoilComponentSelectorCallbackStateV2`, `useRecoilComponentFamilySelectorCallbackStateV2`, `useRecoilComponentStateCallbackStateV2`, `useRecoilComponentFamilyStateCallbackStateV2` - New types: `ComponentSelectorV2`, `ComponentFamilySelectorV2`, `SelectorCallbacksV2` - Extended `buildGetHelper` to support the new selector patterns **State definition migrations:** - `createState()` → `createStateV2()` (Jotai `atom()`) - `createFamilyState()` → `createFamilyStateV2()` (Jotai `atom()` with family cache) - Recoil `selector`/`selectorFamily` → Jotai derived `atom()` via V2 utilities **Hook migrations (~2,400 removed, ~1,545 added V2 equivalents):** - `useRecoilValue` → `useRecoilValueV2` - `useRecoilState` → `useRecoilStateV2` - `useSetRecoilState` → `useSetRecoilStateV2` - `useRecoilCallback` → `useCallback` + `jotaiStore.get/set` - `useRecoilComponentValue` → `useRecoilComponentValueV2` - `useSetRecoilComponentState` → `useSetRecoilComponentStateV2` - `useRecoilComponentFamilyValue` → `useRecoilComponentFamilyValueV2` / `useFamilySelectorValueV2` - ~397 direct `import from 'recoil'` removed **Deleted files (9 files):** - `dateLocaleState.ts` — consolidated - `currentAIChatThreadTitleStateV2.ts` — renamed to replace the original - `isCommandMenuOpenedState.ts` — removed - `filesFieldUploadState.ts` — replaced by V2 - `recordStoreFamilySelector.ts`, `recordStoreFieldValueSelector.ts`, `recordStoreRecordsSelector.ts` — replaced by V2 equivalents - `settingsAllRolesSelector.ts` — replaced by `useSettingsAllRoles` hook - `settingsRoleIdsStateV2.ts` — consolidated **Modules migrated:** - Workflow (diagram, steps, variables, filters) - Page Layout (widgets, fields, graph, tabs) - AI (chat, agents, browsing context) - Activities (rich text editor, targets, timeline) - Action Menu (single/multiple record actions) - Command Menu (navigation, history, pages, workflow) - Context Store - Record Board, Record Table, Record Calendar, Record Index - Record Field, Record Filter, Record Sort, Record Group - Record Drag, Record Picker, Record Store - Views (view bar, view picker, filters, sorts) - Settings (roles, permissions, SSO, security, data model, developers, domains) - SSE (event streams, subscriptions) - Spreadsheet Import - Auth, Favorites, Front Components, Information Banner
