A mechanical prettier --write over server/src, server/tests, server/scripts
and shared/src with the workspaces' .prettierrc; nothing but layout and
import order changes, and every file keeps the same set of imports. shared
is formatted throughout and its format baseline is empty. The server
baseline keeps the 35 files that Prettier would grow past their lint:size
limit (they need a split first, which is not a formatting change), and the
generated entity files stay as their generator writes them.
shared's lint ran eslint --fix with prettier/prettier as an error, so in
lint-prettier.yml the format:check after it only ever saw files it had just
rewritten, and the server's format scripts pointed at a test/ directory that
does not exist. Now lint is check-only in both (lint:fix applies fixes), the
server scripts cover src/ and tests/, and a lint:format ratchet on the shared
library holds every file outside scripts/format-baseline.json to Prettier in
both workspaces: in the server job of test.yml and in lint-prettier.yml,
which keeps providing the lint check. Formatting leaves ESLint in shared, and
the unused eslint-plugin-prettier goes. Once the tree is reformatted in one
commit, --update empties the baselines and the check is a full prettier
--check.
The repositories typed their Kysely statements against 159 table interfaces
written by hand, one or more per repository. Nothing compared them with the
schema: a migration that renamed a column or changed its type left them
stale while tsc stayed green, and several had already drifted
(reservations.accommodation_id is TEXT, not INTEGER).
scripts/generate-db-types.ts migrates a throwaway database with the real
migrations, reads every table back and writes one interface per table into
src/db/kysely/ plus the DB map in db.ts. Every hand-written interface is now
Pick<DB, ...> of that type, and npm run check:db-types fails when the
committed files no longer match the migrations.
A column an insert may leave out (rowid, DEFAULT, nullable) is
InsertOptional<T>, declared as ColumnType<T, T | void, T>. The server
compiles without strictNullChecks, where Kysely's own Generated<T> still
demands the column; that is why the old code kept separate insert-only
interfaces. The ids callers pass as number | string are cast to the column
type at the bind, so every statement binds the same value as before.
