UI Design

Dashboard Layout

  • Sidebar Navigation: Create a responsive sidebar for navigation between different sections.
// components/Sidebar.tsx
import Link from 'next/link';
import styles from './Sidebar.module.css';

const Sidebar = () => (
  <nav className={styles.sidebar}>
    <ul>
      <li><Link href="/tasks">Tasks</Link></li>
      <li><Link href="/plans">Plans</Link></li>
      <li><Link href="/editor">Code Editor</Link></li>
      <li><Link href="/terminal">Terminal</Link></li>
      <li><Link href="/settings">Settings</Link></li>
    </ul>
  </nav>
);

export default Sidebar;

Task Management

  • Task Creation and Editing: Use Markdown for task descriptions.
// pages/tasks.tsx
import { useState } from 'react';
import styles from '../styles/Tasks.module.css';

const Tasks = () => {
  const [tasks, setTasks] = useState([]);
  const [newTask, setNewTask] = useState("");

  const addTask = () => {
    setTasks([...tasks, { description: newTask, status: 'new' }]);
    setNewTask("");
  };

  return (
    <div className={styles.container}>
      <h1>Tasks</h1>
      <input value={newTask} onChange={(e) => setNewTask(e.target.value)} />
      <button onClick={addTask}>Add Task</button>
      <ul>
        {tasks.map((task, index) => (
          <li key={index}>{task.description}</li>
        ))}
      </ul>
    </div>
  );
};

export default Tasks;

Plan Management

  • Specification and Plan Display: Editable fields for specification and proposed plans.
// pages/plans.tsx
import { useState } from 'react';
import styles from '../styles/Plans.module.css';

const Plans = () => {
  const [spec, setSpec] = useState("");
  const [plan, setPlan] = useState("");

  return (
    <div className={styles.container}>
      <h1>Plans</h1>
      <textarea value={spec} onChange={(e) => setSpec(e.target.value)} placeholder="Specification" />
      <textarea value={plan} onChange={(e) => setPlan(e.target.value)} placeholder="Proposed Plan" />
    </div>
  );
};

export default Plans;

Code Editor Integration

  • Code Editor: Use Monaco Editor for an advanced code editing experience.
// pages/editor.tsx
import dynamic from 'next/dynamic';
import styles from '../styles/Editor.module.css';

const MonacoEditor = dynamic(import('react-monaco-editor'), { ssr: false });

const Editor = () => (
  <div className={styles.container}>
    <h1>Code Editor</h1>
    <MonacoEditor
      width="800"
      height="600"
      language="javascript"
      theme="vs-dark"
      options={{ selectOnLineNumbers: true }}
    />
  </div>
);

export default Editor;

Terminal Integration

  • Terminal: Implement a basic terminal using xterm.js.
// pages/terminal.tsx
import dynamic from 'next/dynamic';
import styles from '../styles/Terminal.module.css';

const XTerm = dynamic(() => import('react-xterm'), { ssr: false });

const Terminal = () => (
  <div className={styles.container}>
    <h1>Terminal</h1>
    <XTerm />
  </div>
);

export default Terminal;

Settings Page

  • Settings: Configuration for user preferences and application settings.
// pages/settings.tsx
const Settings = () => (
  <div>
    <h1>Settings</h1>
    <form>
      <label>
        API Key:
        <input type="text" name="apiKey" />
      </label>
      <button type="submit">Save</button>
    </form>
  </div>
);

export default Settings;

Backend Development

API Development

  • API Routes: Use Next.js API Routes for backend logic.
// pages/api/ai/suggest.ts
import { NextApiRequest, NextApiResponse } from 'next';
import axios from 'axios';

export default async (req: NextApiRequest, res: NextApiResponse) => {
  const { prompt } = req.body;

  try {
    const response = await axios.post('https://api.openai.com/v1/engines/gpt-4/completions', {
      prompt,
      max_tokens: 100,
    }, {
      headers: {
        Authorization: `Bearer ${process.env.OPENAI_API_KEY}`,
      },
    });

    res.status(200).json(response.data);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
};

Database Setup

  • Prisma for Database Management: Use Prisma for database interactions.
// prisma/schema.prisma
datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

model Task {
  id          Int      @id @default(autoincrement())
  description String
  status      String
  createdAt   DateTime @default(now())
}

Real-Time Collaboration

WebSocket Integration

  • WebSocket Setup: Use Socket.io for real-time collaboration.
// server.js
const { createServer } = require('http');
const { parse } = require('url');
const next = require('next');
const socketIo = require('socket.io');

const dev = process.env.NODE_ENV !== 'production';
const app = next({ dev });
const handle = app.getRequestHandler();

app.prepare().then(() => {
  const server = createServer((req, res) => {
    const parsedUrl = parse(req.url, true);
    handle(req, res, parsedUrl);
  });

  const io = socketIo(server);

  io.on('connection', (socket) => {
    console.log('New client connected');
    socket.on('updateCode', (code) => {
      socket.broadcast.emit('codeUpdate', code);
    });
    socket.on('disconnect', () => {
      console.log('Client disconnected');
    });
  });

  server.listen(3000, (err) => {
    if (err) throw err;
    console.log('> Ready on http://localhost:3000');
  });
});

Real-Time Code Sharing

// pages/editor.tsx (additional code)
```tsx
import { useEffect, useState } from 'react';
import io from 'socket.io-client';
import dynamic from 'next/dynamic';
import styles from '../styles/Editor.module.css';

const MonacoEditor = dynamic(import('react-monaco-editor'), { ssr: false });
const socket = io();

const Editor = () => {
  const [code, setCode] = useState("");

  useEffect(() => {
    socket.on('codeUpdate', (newCode) => {
      setCode(newCode);
    });

    return () => {
      socket.off('codeUpdate');
    };
  }, []);

  const handleCodeChange = (newCode) => {
    setCode(newCode);
    socket.emit('updateCode', newCode);
  };

  return (
    <div className={styles.container}>
      <h1>Code Editor</h1>
      <MonacoEditor
        width="800"
        height="600"
        language="javascript"
        theme="vs-dark"
        value={code}
        onChange={handleCodeChange}
        options={{ selectOnLineNumbers: true }}
      />
    </div>
  );
};

export default Editor;

Authentication and Security

Authentication with NextAuth.js

  • Implementing Authentication: Use NextAuth.js for secure user authentication.
npm install next-auth
// pages/api/auth/[...nextauth].ts
import NextAuth from 'next-auth';
import Providers from 'next-auth/providers';

export default NextAuth({
  providers: [
    Providers.GitHub({
      clientId: process.env.GITHUB_CLIENT_ID,
      clientSecret: process.env.GITHUB_CLIENT_SECRET,
    }),
  ],
  database: process.env.DATABASE_URL,
});

Securing API Routes

  • Middleware for Protected Routes: Ensure that certain API routes are accessible only to authenticated users.
// pages/api/ai/suggest.ts
import { NextApiRequest, NextApiResponse } from 'next';
import axios from 'axios';
import { getSession } from 'next-auth/client';

export default async (req: NextApiRequest, res: NextApiResponse) => {
  const session = await getSession({ req });
  if (!session) {
    res.status(401).json({ message: 'Unauthorized' });
    return;
  }

  const { prompt } = req.body;

  try {
    const response = await axios.post('https://api.openai.com/v1/engines/gpt-4/completions', {
      prompt,
      max_tokens: 100,
    }, {
      headers: {
        Authorization: `Bearer ${process.env.OPENAI_API_KEY}`,
      },
    });

    res.status(200).json(response.data);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
};

Deployment

Deployment Scripts and Details

    { "src": "server.js", "use": "@vercel/node" }
  ],
  "routes": [
    { "src": "/(.*)", "dest": "/" }
  ]
}
