@openimis/fe-ledger

openIMIS frontend module for openimis-be-ledger_py's double-entry accounting/ledger domain, built against the official specs shipped in this repository under specs/001-ledger-double-entry-accounting/ (spec.md, plan.md, research.md, data-model.md, contracts/graphql-operations.md, tasks.md).

Status: all 7 user stories implemented (spec.md US1–US7)

• US1 — Browse the General Ledger: GeneralLedgerPage, Relay-paginated fetchLedgerEntries with FR-001 default-open-period behavior, baseline expandable/collapsible LedgerEntryGrid with debit/credit/balance subtotals, LedgerFilters.
• US2 — Party Sub-Ledger: PartyLedgerPage, PartyPicker (unified AnalyticValue search), signed balance (utils/balance.js), period statement.
• US3 — Funder Activity: FunderActivityPage, FunderPicker, category breakdown, independent of any party filter.
• US4 — Accounting Periods: AccountingPeriodsPage, open/lock/close/ reopen lifecycle, utils/periodActions.js (chronological-order gating), rejection reasons surfaced verbatim (FR-009).
• US5 — Manual Review Queue: ManualReviewQueuePage (admin-only, even read), ManualReviewResolutionDialog (original entry read-only, FR-012), utils/correctingEntryCandidates.js.
• US6 — Period Export: PeriodExportPage, async export job + pollExportJob polling loop, ExportJobStatus (provisional/final badge, download link, failure message).
• US7 — Deployment Configuration: DeploymentConfigurationPage (admin-only), ForwardOnlyModeWarningDialog (mandatory acknowledgement before an operating-mode change, FR-018).

All routes, the dedicated "Ledger" main menu, and every picker are wired in src/index.jsx.

Deliberately not built (per the spec's own Clarifications — explicitly deferred): the SVAR DataGrid/SVAR Filter enhancement pair. The baseline expandable-table LedgerEntryGrid and plain LedgerFilters fully satisfy the spec's baseline requirements on their own.

Verified, not just written

Unlike a purely-generated skeleton, this module has actually been installed, tested, and built in a sandbox:

• npm test → 55/55 tests passing across 14 suites (reducer, actions, utils, components, and a full-page smoke-test suite rendering all 7 pages against a real Redux store).
• npx vite build → builds cleanly to dist/index.es.js / dist/index.cjs.js.

Doing this surfaced and fixed 7 real bugs that a syntax-only check would have missed:

1. .babelrc (copied from fe-invoice) set modules: false for Vite, which silently broke Jest's ability to parse any file — fixed with a babel env.test override.
2. A file:../openimis-fe-core_js dependency (a leftover from my own local testing) broke npm install entirely — replaced with a proper peerDependency.
3. fetchFunderActivityReport was accidentally deleted by an earlier find-and-replace edit and only caught by the real Vite build, not by any test — restored.
4. DEFUALT_DEBOUNCE_TIME was referenced by PartyPicker/FunderPicker but never (re-)exported from constants.js after a rewrite — restored. 5–7. Missing react-redux/lodash/redux-thunk devDependencies, a test assertion that was flaky against MUI Collapse's async unmount, and a test that queried a MUI Select's MenuItem before opening the dropdown.

Why this replaced the first draft

An earlier draft of this module (before openimis-fe-ledger_js's real specs were found on GitHub) was built purely from a hand-written plan, using openimis-fe-invoice_js conventions (offset pagination, string-interpolated GraphQL, 6 granular rights, entries joining Invoice's "Legal & Finance" menu). Once the actual spec-kit specs were located and read in full, they diverged on nearly every substantive point — see the table below.

Key divergences from the first draft (now corrected)

Aspect	First draft (wrong)	Actual spec (implemented)
Query root fields	ledgerEntry, ledgerEntryLine, partyLedgerReport, ledgerReplicationReviewItem	ledgerEntries (Relay-paginated, embeds lines as legs), partyLedgerBalance, manualReviewQueue, exportSequences
Pagination	offset (formatPageQueryWithCount)	Relay cursor (edges/node/pageInfo/totalCount)
GraphQL call style	string-interpolated (formatMutation)	typed variables (graphqlWithVariables), per research.md §1
Rights	6 granular constants invented	2: RIGHT_LEDGER_REPORTING, RIGHT_LEDGER_ADMIN (still provisional — backend has no RIGHT_ constants yet)
Manual review resolution	arbitrary status field	link to an already-posted correcting entry (same party+period) + note
Period export	mutation returns a direct download URL	async job (exportJob), polled via exportSequences until complete/failed
Main menu	joins Invoice's "Legal & Finance" menu	own top-level "Ledger" menu
Missing entirely	—	Deployment Configuration screen (US7), tree-row grid requirement (FR-023), unified party/funder search via AnalyticValue

Known caveats carried over from the spec itself

• Backend is a stub. openimis-be-ledger_py's schema files are empty; everything here is built against the backend's own design-contract docs. Expect drift once the backend actually ships — this module cannot be integration-tested until then.
• Right IDs are provisional (research.md §3) — coordinate with the backend team before shipping, to avoid colliding with another module's right ID.
• Journal filter is free text, not a picker — no journals reference query exists in the contract (only a journal: String argument).
• The analyticValues(search, tagType) search query behind PartyPicker/FunderPicker is an assumption, not a literal contract — research.md §6 establishes the AnalyticValue-backed search exists but doesn't name the query. Adjust once the backend names it.
• utils/correctingEntryCandidates.js's party/period matching logic is an interpretation: LedgerEntryViewModel has no flat party/period fields, so "the entry's party" is read as "any of its lines is tagged with that party."
• utils/periodActions.js's lock/close/reopen ordering rule is an interpretation of "chronological-order enforcement" (oldest-first for lock/close, newest-first for reopen) — a client-side hint only; the backend mutation response is always authoritative.
