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.
