Technical Highlights

  • Built with Next.js for server-side rendering and client-side interactivity.
  • Utilizes PeerJS with STUN servers for reliable WebRTC connections.
  • Messages are transmitted as structured objects to ensure data integrity, especially for Base64-encoded images.
  • Random usernames are generated using the @scaleway/random-name library.
  • Styled with Tailwind CSS and custom gradient-based avatars.

Usage Guide

This section provides step-by-step instructions on how to use the WRoom effectively.

Prerequisites

  • A modern web browser (e.g., Chrome, Firefox, Edge) with WebRTC support.
  • An internet connection (required for initial peer connection via STUN servers).
  • No additional software installation is needed—just open the application in your browser.

Getting Started

  1. Access the Chat Room

    • Open https://wr.do/chat in your browser.
    • The chat room will automatically initialize and assign you a unique Peer ID.
  2. Create a New Room

    • Upon loading, you are the "owner" of a new chat room by default.
    • Your Peer ID (e.g., abc123-xyz789) is displayed under "Your ID."
    • Share this ID with others to invite them to your room.
  3. Join an Existing Room

    • If you have a room ID from another user, enter it in the "Room ID" field.
    • Click the Connect button to join the room.
    • Once connected, the button will turn green and display "Connected."
  4. Share Your Room

    • Click the Share Room button next to "Your ID" to copy a URL (e.g., https://wr.do/chat?room=abc123-xyz789).
    • Send this URL to others via email, messaging apps, or any preferred method.
    • Recipients can open the URL to join your room directly.

Sending Messages

  1. Text Messages

    • Type your message in the text area at the bottom of the chat window.
    • Press Enter (without Shift) or click the Send button (paper plane icon) to send.
    • Your message will appear on the right side with your username and timestamp, while others' messages appear on the left.
  2. Image Messages

    • Click the Image icon (next to the Send button) to open a file picker.
    • Select an image file from your device (max size: 5MB, supported formats: PNG, JPG, etc.).
    • The image will be sent automatically and displayed in the chat with your username and timestamp.
    • Note: If the image exceeds 5MB, an error toast will appear.

Managing the Chat Room

  • View Users

    • Toggle the sidebar (via the menu icon) to see a list of connected users.
    • The room owner is marked with an "Owner" badge.
    • Each user has a unique gradient avatar based on their username.
  • Create a New Room

    • If you’re the owner, click New Room in the sidebar to reset the current room and generate a new Peer ID.
    • This disconnects all users and starts a fresh session.
  • Disconnect

    • Simply close the browser tab to leave the room. If you’re the owner, the room persists as long as other peers remain connected.

UI Customization

  • Dark Mode: Use the toggle in the top-right corner to switch between light and dark themes.
  • Sidebar: On mobile devices, the sidebar is hidden by default; tap the menu icon to show it.

Troubleshooting

  • Connection Issues: If "Disconnected" appears, check your internet connection or try refreshing the page.
  • Image Not Displaying: Ensure the image is under 5MB and in a supported format. If the issue persists, verify the recipient’s browser console for errors.
  • Peer ID Not Working: Confirm the ID is correct and the room owner is still online.

Notes

  • Limitations: The chat room relies on WebRTC, so firewall or network restrictions may affect connectivity. Images larger than 5MB are blocked to prevent performance issues.
  • Privacy: No messages are stored server-side; all communication is peer-to-peer. However, use caution when sharing sensitive information.
  • Future Enhancements: Potential features include file compression, multi-file support, or end-to-end encryption.

使用指南

本节提供逐步说明,帮助您有效使用 P2P 聊天室。

前提条件

  • 一个支持 WebRTC 的现代浏览器(如 Chrome、Firefox、Edge)。

开始使用

  1. 访问聊天室

    • 在浏览器中打开 https://wr.do/chat
    • 聊天室将自动初始化并为您分配一个唯一的 Peer ID
  2. 创建新房间

    • 加载应用后,您默认成为新聊天室的“拥有者”。
    • 您的 Peer ID(例如 abc123-xyz789)会显示在“Your ID”字段中。
    • 将此 ID 分享给他人,邀请他们加入您的房间。
  3. 加入现有房间

    • 如果您有其他用户的房间 ID,请在“Room ID”字段中输入。
    • 点击 Connect(连接) 按钮加入房间。
    • 连接成功后,按钮将变为绿色并显示“Connected(已连接)”。
  4. 分享您的房间

    • 点击“Your ID”旁边的 Share Room(分享房间) 按钮,复制包含您 Peer ID 的 URL(例如 https://wr.do/chat?room=abc123-xyz789)。
    • 通过电子邮件、消息应用或其他方式将此 URL 发送给他人。
    • 接收者可直接打开 URL 加入您的房间。

发送消息

  1. 文本消息

    • 在聊天窗口底部的文本区域输入消息。
    • Enter 键(不按 Shift)或点击 Send(发送) 按钮(纸飞机图标)发送。
    • 您的消息将显示在右侧,带有您的用户名和时间戳;他人的消息显示在左侧。
  2. 图片消息

    • 点击 Image(图片) 图标(位于发送按钮旁)打开文件选择器。
    • 从设备中选择图片文件(最大 5MB,支持 PNG、JPG 等格式)。
    • 图片将自动发送并在聊天中显示,带有您的用户名和时间戳。

    • 通过菜单图标切换侧边栏,查看连接用户列表。
    • 房间拥有者标有“Owner(拥有者)”徽章。
    • 每个用户拥有基于用户名的独特梯度头像。
  • 创建新房间

    • 如果您是拥有者,点击侧边栏中的 New Room(新房间) 重置当前房间并生成新的 Peer ID。
    • 这将断开所有用户连接并开始一个新会话。
  • 断开连接
