Lightweight 2channel(2ちゃんねる) clone. Works on Cloudflare Workers and Bun.
Like zerochplus or d1ch.cc.

mychanは2ちゃんねる互換の掲示板ソフトウェアです。Cloudflare WorkersかBun上で動作します。

1. Edit config/index.js.
   boards settings are based on 2ch's SETTING.TXT.

   export const config = {
     app: {
       name: 'mychan掲示板' // Website's name
     }
   };
   
   export const boards = {
     poverty: { // Object's key is the board name
       title: {
         name: 'まいちゃん(嫌儲)', // BBS_TITLE, BBS_TITLE_ORIG
         logo: null, // BBS_TITLE_PICTURE
       },
       nanashi: 'セルフホストの名無し', // BBS_NONAME_NAME
       limit: {
         subject: 128, // BBS_SUBJECT_COUNT
         name: 96, // BBS_NAME_COUNT
         mail: 96, // BBS_MAIL_COUNT
         message: 4096, // BBS_MESSAGE_COUNT
         thread: 8 // BBS_THREAD_TATESUGI
       }
     }
   };
