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.
Getting Started with Create React App
This project was bootstrapped with Create React App.
Available Scripts
In the project directory, you can run:
npm start
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
npm test
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
npm run build
Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
npm run eject
Note: this is a one-way operation. Once you eject, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
