Production deploy has been broken since the Next.js migration merged:
the Dockerfile ran `npm ci` right after COPY package*.json, before the
later `COPY . .` that would bring in .npmrc -- so the legacy-peer-deps
fix for react-scripts' stale TS ^4 peer constraint (added for CI in
dbb1580) never took effect in the actual deploy image, and every
deploy since has failed with the same ERESOLVE error CI hit before
that fix. Copy .npmrc alongside package*.json so npm ci sees it.
Wave 6. Swaps react-scripts' build/dev tooling for Next.js while
keeping the app's actual routing/rendering model unchanged -- the app
is almost entirely behind auth with no proven SSR/SEO need, so a real
App Router rewrite would touch ~90 files for zero user-visible benefit.
- next.config.js: output:'export' (static HTML+JS, same "single
index.html served by nginx with try_files fallback" deploy as CRA).
- app/layout.tsx + app/page.tsx: root shell ports public/index.html's
<head>, mounts the whole existing App tree client-only (ssr:false)
since it reads window/localStorage during initial render and Next's
static prerender would otherwise execute that on the server.
- Renamed src/pages/ -> src/views/ (Next's Pages Router auto-detects
any `pages/` dir under the app root and tried to build our React
Router page components as its own routes).
- REACT_APP_* -> NEXT_PUBLIC_* across code, .env.development,
Dockerfile, docker-compose.yml build args.
- Replaced the CRA SVGR import (`ReactComponent` from .svg, unsupported
under Turbopack) with a small inline JobbjaktMark component.
- TypeScript 4.9 -> 5.9 (MUI v8's type-checked build needs syntax
4.9's parser rejects; CRA never hit this because babel doesn't
type-check).
- Dropped CRA-only files (index.tsx, reportWebVitals, react-app-env.d.ts,
public/index.html); kept react-scripts as the Jest test runner only
(next/jest migration not needed -- the existing config already works).
Verified: `next build` static export succeeds, `next dev` serves the
landing page and client-side routes (login etc.) correctly, all 57
frontend tests + 172 backend tests still green.
Known caveat: deep-linking straight to a sub-route (e.g. /login) 404s
in `next dev` since there's no server route for it -- the app only
ever mounts at "/". Production is unaffected: nginx's existing
try_files fallback still serves index.html for any path.
