+# TIF22A_AnwProjekt_B
+Team B im Anwendungsprojekt (TIF22A) 
+
+Website can be accessed under: http://lectureplanner.de/ (caution no https, only http)
+
+
+
+
+
+
+Hinweise für Lokale Installation:
+
+
+Hinweis: Alles ist auf Windows getestet, sollte aber auch auf Mac und Linux funktionieren
+
+1. es sollte java in einer der neusten Versionen installiert sein. (Empfehlung Java 20)
+Downloadlink: https://www.oracle.com/de/java/technologies/downloads/
+Eventuell müssen Sie nach der Installation den PC neu Starten.
+Im Terminal können Sie mit "java -version" Ihre aktuelle Java version überprüfen.
+
+2. Für das Frontend muss zusätzlich npm auf dem Computer installiert sein. (Weiteres siehe z.B. hier: https://docs.npmjs.com/downloading-and-installing-node-js-and-npm)
+
+3. Es sollte feiertagejs installiert sein "npm install feiertagejs" (weiters: https://github.com/sfakir/feiertagejs)
+
+
+
+
+
+Ausführen des Backends (nicht im "backend" ordner):
+
+1. Öffnen Sie ein Terminal, dort wo die datei "backend.jar" liegt. Achten Sie darauf, dass die Dateien "database.mv.db" und "database.trace.db" im gleichen Ordner
+wie die ".jar" Datei liegen.
+
+2. Geben sie im Terminal ein: "java -jar backend.jar"
+
+
+
+
+
+Ausführen des Frontends:
+
+1. Gehen Sie in den Ordner "anwendung"
+
+2. Öffnen Sie hier ein Terminal und führen den Command "npm run build" aus. (Bitte beachten, dass Feiertagejs vorher hier installiert sein sollte)
+
+3. Führen Sie nun im gleichen Terminal den Command "npm run start" aus.
+
+4. Gehen Sie im Browser auf "http://localhost:3000" oder einem davon abeweichenden Link der im Terminal angezeigt wird.
+
+5. Einloggen können Sie sich mit folgenden User-Daten: 
+
+
+Sollte das ausführen lokal nicht funktionieren, können Sie das Projekt immer noch über die website http://www.lectureplanner.de betrachten.

+This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `pages/index.js`. The page auto-updates as you edit the file.
+
+[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.js`.
+
+The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.
+
+This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
+
+Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
