       ### Slack App Setup

       +
       

     

       23
       23
       +
       1. Go to [api.slack.com/apps](https://api.slack.com/apps) and create a new app

     

       24
       24
       +
       2. Choose "From an app manifest"

     

       25
       25
       +
       3. Copy the contents of `slack-manifest.yaml` and paste it

     

       26
       26
       +
       4. Install the app to your workspace

     

       27
       27
       +
       5. Copy the "Bot User OAuth Token" (starts with `xoxb-`) and "Signing Secret"

     

       28
       28
       +
       6. Invite the bot to your desired Slack channel: `/invite @IRC Bridge`

       The bridge provides interactive slash commands for managing mappings:

     

       72

       +
       

     

       73
       73
       +
       - `/irc-bridge-channel` - Bridge current Slack channel to an IRC channel

     

       74
       74
       +
       - `/irc-unbridge-channel` - Remove bridge from current channel

     

       75
       75
       +
       - `/irc-bridge-user` - Link your Slack account to an IRC nickname

     

       76
       76
       +
       - `/irc-unbridge-user` - Remove your IRC nickname link

     

       77
       77
       +
       - `/irc-bridge-list` - List all channel and user bridges

       ### Managing Channel and User Mappings

     

       80
       80
       +
       

     

       81
       81
       +
       Channel and user mappings are stored in a SQLite database (`bridge.db`). You can manage them through:

     

       82
       82
       +
       

     

       83
       83
       +
       **Using Bun REPL:**

     

       84
       84
       +
       ```bash

     

       85
       85
       +
       bun repl

     

       86
       86
       +
       > import { channelMappings, userMappings } from "./src/lib/db"

     

       87
       87
       +
       > channelMappings.create("C1234567890", "#general")

     

       88
       88
       +
       > userMappings.create("U1234567890", "myircnick")

     

       89
       89
       +
       > channelMappings.getAll()

     

       90
       90
       +
       ```

     

       91
       91
       +
       

     

       92
       92
       +
       **Using SQLite directly:**

     

       93
       93
       +
       ```bash

     

       94
       94
       +
       bun:sqlite bridge.db

     

       95
       95
       +
       sqlite> SELECT * FROM channel_mappings;

     

       96
       96
       +
       sqlite> INSERT INTO channel_mappings (slack_channel_id, irc_channel) VALUES ('C1234567890', '#general');

     

       97
       97
       +
       ```

     

       98
       98
       +
       

     

       99
       99
       +
       ### How it works

     

       100
       100
       +
       

     

       101
       101
       +
       The bridge connects to `irc.hackclub.com:6667` (no TLS) and forwards messages bidirectionally based on channel mappings:

     

       102
       102
       +
       

     

       103
       103
       +
       - **NickServ Authentication**: If `NICKSERV_PASSWORD` is configured, the bridge authenticates on connect

     

       104
       104
       +
         - Waits for NickServ confirmation before joining channels

     

       105
       105
       +
         - Auto-registers the nick if not registered (requires `NICKSERV_EMAIL`)

     

       106
       106
       +
         - Prevents "No external channel messages" errors by ensuring proper authentication

     

       107
       107
       +
       - **IRC → Slack**: Messages from mapped IRC channels appear in their corresponding Slack channels

     

       108
       108
       +
         - Image URLs are automatically displayed as inline attachments

     

       109
       109
       +
         - IRC mentions (`@nick` or `nick:`) are converted to Slack mentions for mapped users

     

       110
       110
       +
         - IRC formatting codes are converted to Slack markdown

     

       111
       111
       +
         - IRC `/me` actions are displayed in a context block with the user's avatar

     

       112
       112
       +
         - Thread replies: Use `@xxxxx` (5-char thread ID) to reply to a Slack thread from IRC

     

       113
       113
       +
       - **Slack → IRC**: Messages from mapped Slack channels are sent to their corresponding IRC channels

     

       114
       114
       +
         - User display names: Uses name from Slack event if available, otherwise Cachet API (if `CACHET_ENABLED=true`), then Slack API fallback

     

       115
       115
       +
         - All lookups are cached locally (1 hour TTL) to reduce API calls

     

       116
       116
       +
         - Slack mentions are converted to mapped IRC nicks, or looked up via the above priority

     

       117
       117
       +
         - Slack markdown is converted to IRC formatting codes

     

       118
       118
       +
         - File attachments are uploaded to Hack Club CDN and URLs are shared

     

       119
       119
       +
         - Thread messages are prefixed with `@xxxxx` (5-char thread ID) to show they're part of a thread

     

       120
       120
       +
         - First reply in a thread includes a quote of the parent message

     

       121
       121
       +
       - **User mappings** allow custom IRC nicknames for specific Slack users and enable proper mentions both ways

     

       122
       122
       +
       - **Permissions**: Only channel creators, channel managers, or global admins can bridge/unbridge channels

     

       123

       #### Thread Support

     

       125
       125
       +
       

     

       126
       126
       +
       The bridge supports Slack threads with a simple IRC-friendly syntax:

     

       127
       127
       +
       

     

       128
       128
       +
       - **Slack → IRC**: Thread messages appear with a `@xxxxx` prefix (5-character thread ID)

     

       129
       129
       +
         - First reply in a thread includes a quote: `<user> @xxxxx > original message`

     

       130
       130
       +
         - Subsequent replies: `<user> @xxxxx message text`

     

       131
       131
       +
       - **IRC → Slack**: Reply to a thread by including the thread ID in your message

     

       132
       132
       +
         - Example: `@abc12 this is my reply`

     

       133
       133
       +
         - The bridge removes the `@xxxxx` prefix and sends your message to the correct thread

     

       134
       134
       +
         - Thread IDs are unique per thread and persist across restarts (stored in SQLite)

     

       135
       135
       +
       

     

       136
       136
       +
       The bridge ignores its own messages and bot messages to prevent loops.

     

       137
       137
       +

       140
       140
       +

       141
       141
       +
       

     

       142

       150
       150
       +

       153
       153

       ### Testing

     

       155
       155
       +
       

     

       156
       156
       +
       The project includes comprehensive unit tests covering all core functionality:

     

       157
       157
       +
       

     

       158

       +
       bun test

     

       160
       160
       +
       ```

     

       161
       161
       +
       

     

       162
       162
