Le code avait beaucoup évolué depuis la dernière mise à jour de la
documentation (sources externes, import de recettes, planning en
grille, pages de paramètres, thème, tests Cucumber...) sans que
README.md/specs/*.md ne suivent. Tour complet du code (backend +
frontend) et réécriture :
- specs/batch-cooking-modele.md : schéma de données réécrit depuis
schema.prisma (foyer/admin/invitation, sources, catalogue
ingrédients/unités, techniques détectées, visibilité des recettes).
- specs/backend-architecture.md : foyer, préférences/goûts, planning,
référence, sources externes (adaptateurs/registre/sync), matching
ingrédients/techniques, isolation base de test, suppression de compte.
- specs/frontend-architecture.md : routing complet, sidebar/paramètres,
thème, planning + picker, catalogue + import, composants UI partagés,
tests Cypress+Cucumber.
- specs/batch-cooking-architecture.md : module Import passe de TODO à
implémenté.
- specs/error-handling.md : liste complète des ~19 codes d'erreur.
- README.md : réécriture pour refléter tout ce qui précède, plus la
note (dangereusement obsolète) sur le partage base de test/dev — le
fix existe déjà (apps/api/.env.test), la doc décrivait encore le bug.
Retour fonctionnel : allergies et intolérances doivent être distinguées
dans l'UI, et /foyer doit sauvegarder à la volée plutôt que via des
boutons "Enregistrer".
- AllergySelect prend un `legend` en prop au lieu d'un libellé interne
fixe — le même composant est rendu deux fois par chaque page
consommatrice (HouseholdPage, OnboardingAllergensPage), une fois par
`kind` (ALLERGY / INTOLERANCE), la sélection restant une seule liste
d'IDs partagée.
- HouseholdPage : suppression des boutons "Enregistrer", autosave
déclenché depuis le handler onChange de chaque champ (jamais un
useEffect générique sur la valeur — se déclencherait aussi au
chargement initial, sans distinction propre "chargé" vs "modifié").
Nom du foyer et allergènes/intolérances debouncés (600ms/500ms),
régime sauvegardé immédiatement (sélection discrète). Validation
client (nom vide) empêche l'autosave plutôt que de déclencher un
aller-retour API voué à l'échec.
- i18n : household.form.allergiesLabel devient "Allergies" (au lieu de
"Allergies & intolérances"), nouvelle clé intolerancesLabel, save/
saved remplacés par saving/saved (plus de bouton à libeller).
- Cypress (household.cy.ts réécrit, onboarding.cy.ts mis à jour) +
specs/frontend-architecture.md + README.md.
Vérifié dans le navigateur : wizard d'inscription affiche bien les
deux groupes (12 allergies / 2 intolérances) ; /foyer sans aucun
bouton, chaque section sauvegarde automatiquement (vérifié en base
après édition du nom du foyer et du régime) ; compte de test nettoyé.
Clôt le retour fonctionnel sur la feature profil/foyer/régime/
allergènes (8 commits au total sur cette PR).
- apps/web/cypress/e2e/onboarding.cy.ts — parcours complet (rempli et
entièrement skippé) signup → 3 étapes → home, mêmes conventions
cy.intercept que le reste.
- apps/web/cypress/e2e/household.cy.ts — /foyer : préremplissage, et
sauvegarde indépendante de chacune des 3 sections.
- specs/frontend-architecture.md : nouvelle section "Parcours profil —
foyer, régime, allergènes" (diagramme mermaid, les deux bugs de state
trouvés en testant dans le navigateur), arborescence et namespaces
i18n à jour.
- README.md : nouvelle section "Parcours profil — foyer, régime,
allergènes", section sidebar mise à jour (Foyer & profil n'est plus
un stub).
Cypress lui-même ne peut pas tourner en local dans ce sandbox (voir la
note existante dans le README) — vérifié via `tsc --noEmit` sur les
specs + parcours manuel complet dans le navigateur (les deux à travers
les 5 commits précédents de cette feature).
Clôt la feature profil/foyer/régime/allergènes (6 commits, cette PR) :
seed+référence -> endpoints foyer/profil -> composants partagés ->
wizard d'inscription -> page /foyer -> ce commit.
- New apps/web/cypress/e2e/home-planning.cy.ts (mocked API, same
cy.intercept convention as auth.cy.ts):
- sidebar nav between sections + active-link highlighting
- user name + logout from the sidebar footer
- home planning: empty / loaded (table rows) / error states
- specs/frontend-architecture.md: documents AppLayout (single
RequireAuth+AppLayout parent route, nested routes via <Outlet />),
the ComingSoonPage stub pattern, updated folder tree and i18n
namespace list, updated routing diagram.
- README.md: new "Accueil, sidebar & sections" section; notes the
Cypress-can't-run-headless-here environment limitation (confirmed
pre-existing on main) and the docker-vs-local-dev CORS_ORIGIN gotcha
hit while manually verifying this feature.
Closes out the home-page-after-login feature (5 commits, this PR):
GET /planning/current -> AppLayout -> routing/stub pages -> HomePage
planning view -> this commit.
* Centralize error handling (shared codes + API/client services), code quality pass
## Error handling
Requested: a centralized error-handling service on the API, custom error
codes shared across apps, and a client-side error service for i18n labels.
- packages/shared/src/errors/error-codes.ts — ErrorCode enum + ApiErrorResponse
contract. Single source of truth: neither side hardcodes a raw error string
the other has to guess at.
- apps/api: HttpError now carries an ErrorCode (not just a message).
ErrorHandlerService (new) centralizes every "how do we turn a thrown error
into an HTTP response" decision — app.ts's error middleware is now a thin
adapter calling into it. API messages reverted to English/dev-facing (they
were French from an earlier pass) since user-facing text is now generated
client-side from the code.
- apps/web: ApiClient (class, singleton instance) throws ApiError carrying
the code. ErrorMessageService (new) maps every ErrorCode to a localized
label, structured with a Locale type from the start (only "fr" exists, but
adding a language later is "add a locale to the map", not "hunt down every
hardcoded string"). LoginPage/SignupPage now display
errorMessageService.getLabel(err.code), never err.message directly.
- Tests strengthened to assert on `code`, not just HTTP status (Mocha +
Cucumber, new "the response error code should be" step). Cypress mocks
updated to the new {code, message} response shape.
## Code quality pass
Per explicit feedback: heavy JSDoc on every interface/type/class/function/
method/member touched in this PR, explicit public/private visibility on
every class member (ApiClient, ErrorMessageService, ErrorHandlerService,
HttpError), no HTML/logic mixing (styling extracted out of components
entirely, never inline).
ApiClient/ErrorMessageService were initially written as static-only classes;
switched to instance-based singletons (matching ErrorHandlerService's
existing pattern) after Biome's noStaticOnlyClass rule flagged the
static-only shape as an anti-pattern — same "class with visibility
modifiers" outcome, without fighting the linter.
## SCSS + theming
- apps/web/src/styles/_theme.scss — design tokens as CSS custom properties
on :root (colors, spacing, typography), not plain Sass variables — makes
them available at runtime, not just compile time, so a future theme
switch (e.g. dark mode) is "redefine these variables" rather than
rebuilding stylesheets.
- apps/web/src/styles/global.scss replaces the old single index.css:
reset + theme import only, loaded once from main.tsx.
- Per-page/component styles colocated (HomePage.tsx + HomePage.scss);
styles shared by multiple pages within one feature live in that feature's
folder (features/auth/auth-form.scss, used by both Login/SignupPage) —
not duplicated per page, not dumped in the global stylesheet either.
- Component-level .scss files intentionally don't `@use` the theme
partial: they only consume CSS custom properties (global at runtime via
global.scss), not Sass-level symbols, so importing it would do nothing —
documented inline rather than left as a silently-redundant import.
- vite.config.ts opts into Sass's modern compiler API to silence a
legacy-js-api deprecation warning on every build.
## specs/ updates
- New specs/error-handling.md — the ErrorCode/ApiErrorResponse contract,
both services, with a flow diagram.
- New specs/frontend-architecture.md — apps/web folder structure, routing/
auth-guard flow, SCSS/theming conventions.
- specs/batch-cooking-architecture.md links to both (original doc content
otherwise untouched — it's the user's own hand-authored source doc).
## Verification
Full lint/mocha/cucumber/build green. Manually re-verified the whole auth
flow in a real browser against native dev servers (not just the automated
suites): signup, the EMAIL_ALREADY_IN_USE → "Cet email est déjà utilisé"
translation end-to-end (confirmed the raw API response carries the English
dev message + code, and the UI shows the French label), wrong-password
INVALID_CREDENTIALS → its label, and confirmed the theme tokens actually
apply (computed button background-color matches --color-primary, card
max-width matches the token value) rather than trusting the build succeeding.
* Address review: no .d.ts, express-tools package, faker fixtures, numeric codes, real i18n lib
Five explicit review points, addressed on this same PR branch (not a new
PR) per updated preference.
## No .d.ts files in the codebase
- apps/web: vite-env.d.ts removed — its /// <reference types="vite/client" />
is replaced by "types": ["vite/client"] in tsconfig.app.json, same effect.
- apps/api: src/types/express.d.ts renamed to express-request.augment.ts —
`declare global` module augmentation works identically in a plain .ts
file as long as it has a top-level import (making it a module); the
.d.ts extension wasn't doing anything for us here.
## packages/express-tools — separate package for Express tooling
Moved HttpError and ErrorHandlerService out of apps/api into a new
workspace package, plus a new createErrorMiddleware() factory (the actual
Express 4-arg error-handling middleware, previously inlined in app.ts).
apps/api now just consumes @batch-cooking/express-tools. Has a real build
(tsc -> dist/, same pattern as packages/shared) — required for the same
reason shared needed one: apps/api's Docker image runs plain `node
dist/server.js`, no tsx. apps/api/Dockerfile updated to COPY the new
package's dist alongside shared's.
## faker.js for test fixtures
apps/api/test/auth.test.ts: replaced the hardcoded "Nicolas
Lefevre"/nicolas@example.com fixture (looked like real user data) with
@faker-js/faker, generated fresh per test via buildSignupPayload().
features/step-definitions/auth.steps.ts: fakerized the filler
firstName/lastName/password used for background state the scenarios
don't actually read.
Deliberately did NOT fakerize the literal example values inside
auth.feature itself (alice@example.com etc.) — those are the readable,
illustrative Gherkin examples that are the whole point of BDD scenarios,
not real PII, and randomizing them would make the scenarios harder to
read for no real gain. Flagged this reasoning in the README in case that
call should go the other way.
Caught a real bug while wiring this up: faker.internet.email() sometimes
capitalizes parts of the address, but signupSchema/loginSchema normalize
emails to lowercase — the test fixture needs to match what's actually
stored, so buildSignupPayload() lowercases the generated email too.
Found by actually running the suite repeatedly, not just once.
## ErrorCode: numeric enum, zero hardcoded values
packages/shared/src/errors/error-codes.ts: ErrorCode is now a numeric
enum (4000 VALIDATION_ERROR, 4001 EMAIL_ALREADY_IN_USE, 4010
INVALID_CREDENTIALS, 4011 NOT_AUTHENTICATED, 4040 NOT_FOUND, 5000
INTERNAL_ERROR — grouped by family like HTTP status codes).
Audited and fixed every place that hardcoded a raw code value instead of
referencing the enum: ApiClient's fallback (`"INTERNAL_ERROR" as
ErrorCode` — would no longer even type-check once the enum went numeric,
which is exactly the point), and the Cypress mock bodies (now import
ErrorCode from @batch-cooking/shared instead of typing the string).
Cucumber's "the response error code should be {string}" step still takes
the *name* in the .feature file (readable: "EMAIL_ALREADY_IN_USE") and
resolves it to the real numeric value via ErrorCode[name] — TypeScript's
reverse enum mapping — before comparing, so the Gherkin stays readable
without the step hardcoding a number either.
## Real i18n library (i18next), not a hand-rolled label map
apps/web: added i18next + react-i18next. New locales/fr/translation.json
holds every user-facing string — not just error labels (errors.*), but
the login/signup/home pages' labels, buttons and headings too
(auth.login.*, auth.signup.*, home.*) — via useTranslation()/t() in each
page. ErrorMessageService no longer owns its own label map; it converts
the numeric ErrorCode to its enum member name and delegates the actual
lookup to i18next (errors.<MEMBER_NAME>). Adding a language is now
"add a locale file", not a code change anywhere.
## specs/ and README updated
specs/error-handling.md and specs/frontend-architecture.md rewritten for
the new package, numeric codes, and i18next. New "i18n" and "no .d.ts"
sections. README covers the same, plus a note on the faker.js scope
decision (feature-file literals excluded, on purpose).
## Verification
Full lint/mocha (x3 runs)/cucumber/build green. Re-verified
express-tools' extraction against a real risk (not just tsc passing):
ran `node dist/server.js` standalone (mirrors the Docker runtime, no
tsx) and hit /health, a 404 (confirmed numeric code 4040 over the wire),
and a real signup + duplicate-email 409 (confirmed numeric 4001). Then
re-verified the full pipeline in a real browser against native dev
servers: signup, EMAIL_ALREADY_IN_USE -> i18next -> "Cet email est déjà
utilisé" end-to-end, home page i18next interpolation
({{firstName}}/{{lastName}}) rendering correctly.
* Address second review round: interface comments, res.locals, ExpressServer, assertIsNever
Five more explicit review points, on the same PR branch.
## Every interface key commented
Audited all 6 interfaces in the codebase. Two had partially-commented
members (violates the "every key gets /** */" rule): AuthResult
(apps/api/auth.service.ts) and SafeUserProfile (packages/shared) — both
now fully commented. The other four (AuthTokenPayload,
AuthContextValue, ErrorHandlingResult, ApiErrorResponse) were already
compliant.
## Removed the Express namespace augmentation
apps/api/src/types/express.d.ts (renamed to express-request.augment.ts
in the last round) is gone entirely. requireAuth now attaches the
authenticated profile to `res.locals.userProfile` — Express's own
built-in per-request mechanism for exactly this — typed via a new
AuthLocals interface and `Response<unknown, AuthLocals>`, instead of a
project-wide `declare global` silently changing every Request's type
whether or not it went through the middleware.
## ErrorHandlerService confirmed framework-agnostic
It already had zero Express import. Documented this explicitly (in the
package's index.ts and the new backend-architecture.md spec) as a
deliberate split: ErrorHandlerService is framework-agnostic (would work
behind Fastify too), ExpressServer/createErrorMiddleware are the actual
Express integration layer.
## packages/express-tools: server init + route/middleware utilities
New ExpressServer class, modeled on the pattern shared as a reference
(adapted, not copied 1:1 — deliberately left out the reference's custom
runtime param-type-validation system, since zod already does that job
in this codebase and running two parallel validation mechanisms would
be redundant, not "propre"):
- setupCore() — the common cors/json/cookie-parser stack
- addRoute() — registers a route, warns+skips instead of silently
double-registering the same method+path
- addMiddleware() / mountRouter() / setErrorHandler()
- listen()
- .instance — the raw Express app, for supertest
Also added wrapAsyncHandler() — forwards a thrown/rejected error from an
async handler to next(err) automatically, removing the manual
try/catch/next(err) every route needed.
apps/api/src/app.ts now builds via ExpressServer (createServer(),
consumed by both server.ts's .listen() and createApp()'s .instance for
tests). auth.routes.ts's signup/login handlers use wrapAsyncHandler
instead of manual try/catch. cookie-parser/cors moved out of apps/api's
own dependencies entirely — they're express-tools' concern now.
## assertIsNever (packages/shared/src/tools/)
Exhaustiveness-check helper for switch/if-chains over a union: takes a
`never`-typed value and throws, so a forgotten case in a later-added
union member becomes a compile error instead of a silent runtime
fallthrough. Verified for real (not just written and assumed correct):
wrote a throwaway switch missing a case and confirmed `tsc` rejects it
with the exact expected error, then deleted the scratch file. No
existing switch/if-chain over a union in the codebase yet to retrofit
it into — noted as ready for when one appears (e.g. the not-yet-built
batch-cooking calculation module or recipe-import pipeline).
## specs/ updated
New specs/backend-architecture.md — ExpressServer, wrapAsyncHandler,
the res.locals decision (with the "why not declare global" reasoning
spelled out), assertIsNever. error-handling.md and
frontend-architecture.md cross-link to it instead of duplicating.
README covers the same, briefly.
## Verification
Full lint/mocha/cucumber/build green. Re-ran `node dist/server.js`
standalone (mirrors Docker, no tsx) after the ExpressServer refactor:
/health, a 404 (numeric 4040), and a real signup + GET /me round trip
confirming res.locals-based auth actually works at runtime, not just
that tsc accepts the types.
* refactor: move ErrorHandlerService/HttpError out of express-tools
ErrorHandlerService has zero dependency on Express — it's a plain
"map an error to {status, body}" service that works identically
behind any HTTP framework. It had no business living in a package
named express-tools.
Extracted HttpError, ErrorHandlerService, and ErrorHandlingResult
into a new packages/error-tools package (same tsc-build-to-dist
pattern as shared/express-tools). express-tools now only keeps the
actual Express-specific layer: ExpressServer, wrapAsyncHandler, and
createErrorMiddleware (which adapts ErrorHandlerService, imported
from error-tools, onto Express).
- packages/error-tools: new package, depends on shared + zod
- packages/express-tools: drops zod dependency, adds error-tools
dependency for error-middleware.ts's type import
- apps/api: adds error-tools dependency; app.ts, auth.service.ts,
require-auth.ts now import HttpError/errorHandlerService from
error-tools instead of express-tools
- apps/api/Dockerfile: adds COPY for packages/error-tools in the
runtime stage
- specs/error-handling.md, specs/backend-architecture.md, README.md
updated to reflect the new package split
Verified: pnpm lint, pnpm build (all packages, correct dependency
order), pnpm test (9/9 Mocha), pnpm test:bdd (5/5 Cucumber), full
Docker rebuild + compose up (no crash-loop), curl + browser checks
of /health, unknown-route 404, signup (201), duplicate-email 409
(code 4001 EMAIL_ALREADY_IN_USE) — all going through the moved
ErrorHandlerService/HttpError correctly.
