Naming

The names that are load-bearing across both projects, and the ones that are only conventions.

Last verified: 2026-07-30 against commit d3ec723.


The two names, and why there are two

The product and brand are Balinyaar (Persian: «بالین‌یار»). The server's code namespace is Baya* — a legacy prefix from before the name settled.

Layer Name Rule
Server namespaces, projects, solution Baya.* / Baya.sln Keep it. Do not rename without explicit instruction — it touches 14 .csproj files, every namespace, and the solution.
Client package balinyaar-client
Client import alias @/*client/src/* Defined in client/tsconfig.json. Use it; don't write deep relative paths across folders.
User-facing copy «بالین‌یار» / "Balinyaar" Never Baya. See client/i18n.md for the ZWNJ rule — it is linted.

So Baya.Application is correct in C# and wrong in a UI string, and «بالین‌یار» is correct in a UI string and would be wrong as a namespace. That is the whole split.


Agent-facing docs

CLAUDE.md is the single source of truth at every level of the repo. AGENTS.md files exist only so the convention is discoverable under that name too — they are thin pointers, never content. If you find yourself writing a rule into an AGENTS.md, it belongs in the CLAUDE.md beside it.

Three AGENTS.md files exist: repo root, client/, server/.


Server naming

Full C# conventions in server/conventions.md. The names that matter beyond style:

Kind Convention Example
Command {Verb}{Noun}Command CreateOrderCommand
Query {Verb}{Noun}Query GetUserOrdersQuery
Handler {RequestName}Handler CreateOrderCommandHandler
Result DTO {RequestName}Result CreateOrderCommandResult
Feature folder Features/<Area>/{Commands|Queries}/<VerbNoun>/ Features/Payments/Commands/InitiatePayment/
EF config folder Persistence/Configuration/<Area>Config/ PaymentsConfig/
Seam interface I{Capability} in Application/Contracts/ IBankTransferProvider
Real adapter {Vendor}{Capability} in Seams/Real/ JibitBankTransferProvider
Mock adapter Mock{Capability} in Seams/ MockBankTransferProvider

Controller and action names become URLs. All URL segments are snake_case, produced automatically from [controller]/[action] tokens by SnakeCaseParameterTransformer. So GetBySlug becomes get_by_slug. If a method name doesn't read cleanly as a URL, rename the method — never hardcode the route string, which bypasses the transformer.

One type per file, and the file name matches the type name exactly.


Client naming

Kind Convention Example
Shared component src/components/<Name>/<Name>.tsx + index.tsx barrel components/TrustBadge/TrustBadge.tsx
Its test co-located <Name>.test.tsx components/TrustBadge/TrustBadge.test.tsx
Page body <PageName>Screen.tsx, co-located with page.tsx HomeScreen.tsx, SearchScreen.tsx
Private (non-route) folder under app/ _-prefixed _chrome/, _hub/
Route group (adds no URL segment) parenthesised (customer), (public-routes)
Service domain src/services/{domain}/ services/bookingRequests/
Query hook one per file, hooks/use{Action}.ts hooks/useBookingDetail.ts
Icon registry key lowercase, semantic icon="verification", not icon="ShieldCheck"
i18n namespace a top-level key in both message files booking, payouts
Constant SCREAMING_SNAKE in a constants.ts APP_FRAME_MAX_WIDTH

bookings and bookingRequests are siblings, not a rename — a booking request is the money-free pre-payment intent, a booking exists only after capture. The same distinction is load-bearing in Persian copy («درخواست رزرو» vs «رزرو») and in the server's singular Booking vs plural Bookings feature areas.


Directory conventions that carry meaning

Path Meaning
client/src/components/common/ Foundational primitives, imported via @/components
client/src/components/<domain>/ Domain composites (booking/, messaging/, admin/, geography/, notifications/, settings/, auth/)
client/src/services/{domain}/apis/ The seam: clientApi.ts (real), mockApi.ts, serverApi.ts, index.ts (selects)
server/src/Core/ Domain + Application — no outward dependencies
server/src/Infrastructure/ Implementations of Application contracts
server/src/API/ Controllers, framework, plugins
dev/ The finished build-plan chain. History, not a project — nothing to build in it
product/ Business truth. Markdown canonical, HTML generated
