# 🤖 Memebot: Discord Meme Management System
Memebot is a project that combines a **Discord Bot** and a **Web Frontend interface** to provide an efficient and customizable platform for community members to store, manage, and use their meme images.
## 🎯 Project Goals
* Provide an efficient Discord bot implemented in **Go** that can trigger meme output based on keywords.
* Build a **React + TypeScript** driven web interface to facilitate users in viewing, uploading, and managing memes and their custom aliases.
* Implement a **Many-to-Many** relationship model: one image can have multiple aliases, and one alias can also correspond to multiple images.
---
## 🏗️ System Architecture (Topology)
The project utilizes a microservice concept, dividing the functionality into three main components: the Discord Bot, the Web Backend (API), and the Web Frontend, all interacting with a shared Database/Storage.
<div style="text-align:center;">
    <img src="https://hackmd.io/_uploads/H1eUrs-f-l.png" width="70%"/>
</div>
---
## 🤖 Discord Bot Features
The bot is responsible for two main functions: image management and automated responses.
### 1. Image Trigger and Response
* **Trigger Mechanism:** The bot monitors chat messages. Once it detects that the message content contains any pre-defined **Alias**, it triggers a response.
* **Matching Algorithm:** For high-efficiency, real-time matching across a large set of aliases, we will use the **Aho-Corasick algorithm**.
* **Output Logic:** If the alias `<alias>` is matched, the bot will **randomly select** and send one image associated with that `<alias>` to the channel.
### 2. Discord Commands (Slash Commands)
| Command | Description |
| :--- | :--- |
| `/image upload` | Uploads an image. **Must include an image attachment** (JPG/PNG/GIF). The bot generates a unique **Image ID** (e.g., `670bc00e94fd77cf6852afc7`) and stores it. |
| `/image link alias: <alias> image: <image_ID>` | Adds or links an `<alias>` to the specified `<image_ID>`. |
---
## 🌐 Web Frontend Interface
The interface is built using **React + TypeScript** with **Tailwind CSS** to provide a user-friendly, visual management tool that is more convenient than using Discord commands alone.
### Page Layout and Functions
* **Navbar:** Displays the Bot's name on the left and contains **[Upload Image]** and **[Login]** buttons on the right.
* **Left Sidebar:** Serves as a **Table of Contents** for all **Aliases**. The last entry is for "**Images without aliases**".
* **Search Bar:** Located at the top of the right content area, featuring **real-time feedback** search functionality.
* **Content Area:** Displays image thumbnails grouped by their corresponding Alias.
### 1. 🔎 View and Management (Find)
* **Image Preview:** Clicking any image thumbnail will open a **floating window (Modal)**.
* **Image Information:** The modal will display the image, its uploader, upload time, and all associated Aliases.
* **Editing Features:** Users can edit Aliases or delete the image from this modal (login required).
### 2. ⬆️ Upload Image
Clicking the **[Upload Image]** button opens a modal for submission:

# Go Final Project
主題Discord 機器人,功能是存放一些梗圖,然後讓 Discord user 可以自行新增圖片、自定義 alias、根據 alias 叫出圖片。
除了 Discord bot 之外,還會有一個前端的網頁可以方便使用者查看、編輯這些圖片。
## Topology
<div style="text-align:center;">
<img src="https://hackmd.io/_uploads/H1eUrs-f-l.png" width="70%"/>
</div>
## Discord Bot Command (Draft)
圖片與 alias 的對應:多對多,一張圖片可以有很多 aliases一個 alias 也可以對應到很多張圖片。
輸出圖片是被動觸發的:只要在使用者的聊天訊息偵測到特定關鍵詞(聊天訊息包含任意一個 alias以第一個匹配成功的為主匹配方式我們打算使用 Aho-Corasick algorithm 因為我們準備 ICPC 的時候學過),假設該 alias 是 `<alias>`bot 會從含有該 `<alias>` 的圖片隨機挑選一個輸出。
在 Discord 對話框輸入 `/image upload` 並附上一個圖片檔(可以是 JPG/PNG/GIFbot 會為這張圖片生成隨機一個唯一的 ID`670bc00e94fd77cf6852afc7`),並將這個圖片存在 Database。
在 Discord 對話框輸入 `/image link alias: <alias> image: <image_ID>`,會為該圖片新增一個 alias。
## Web Backend API (Draft)
- `GET /api/image/<image_ID>`:取得某張圖片檔案。
- `GET /api/image-list`:列出 db 內所有圖片檔案名稱。
- `GET /api/alias-list`:列出 db 內所有 alias。
- `/auth/gen-access-url`:預計使用 token-JWT exchange based authentication 來作為使用後端 API 的身分驗證。
其實應該還要有很多,還沒想清楚。
## Web Frontend
除了 Discord bot 之外,預計用 React + TypeScriptCSS 用 Tailwind寫一個前端網頁。
前端網頁大概長這樣:
```
Memebot [Upload-Image] [Login]
---------------------------------------------------------------
[ sadge ] ( Search Bar )
[ 不要吼我啦 ]
[ 什麼都願意做 ] Alias: 什麼都願意做
[ 好時代來臨力 ] [ 方形圖片框1 ] [ 方形圖片框2 ] [ 方形圖片框3 ]
[ 野獸 ] [ 方形圖片框4 ]
[ poop ]
[ rrrrr ] Alias: 好時代來臨力
[ 讓我看看 ] [ 方形圖片框1 ] [ 方形圖片框2 ]
[ 我愛慕虛榮啦 ]
[ 一輩子 ] Alias: 野獸
[ 是又怎樣 ] [ 方形圖片框1 ] [ 方形圖片框2 ] [ 方形圖片框3 ]
[ Img w/o alias ]
```
上方是 Navbar
- Navbar 左側是我們的 Bot 名稱。
- Navbar 右側是功能按鈕,目前只有 Upload Image、Login。
### Find
- 左側 sidebar 是所有 aliases 的 table of content。類似 HackMD、mdBook 瀏覽某篇文章的功能。
- 最後一列是「尚未有暱稱的圖片」。
- 右側緊接在 Navbar 底下是 search bar
- search bar 是即時反饋,使用者不需要按 enter 就會自動列出符合當前條件的圖片們。
- 右側在 search bar 下方是各個 alias 對應的圖片們。
- 點一下圖片之後會跳出一個浮動視窗顯示這張圖片以及圖片相關資訊包含誰upload 這張圖片、什麼時候 upload 這張圖片、alias 有哪些),以及可以在這裡編輯 alias、刪除圖片。
### Upload Image
使用者按下這個按鈕之後,跳出一個浮動視窗:
```
======================================
| |--------------------------------| |
| | | |
| | | |
| | Drag your image here | |
| | | |
| | | |
| |--------------------------------| |
| |
| Aliases of this image: |
| [ alias_01 ] |
| [ alias_02 ] |
| [+] [ (Add a new alias) ] |
| |
| <Upload> |
======================================
```
### Login
驗證當前操作前端的 Discord User未登入的話只能使用查看相關的操作不能編輯、上傳、刪除。
這個有空再來做。
