KOKOTO WebChat

KOKOTO WebChat

BlueMapWebChat → KOKOTO WebChat transition

BlueMapWebChat has been renamed to KOKOTO WebChat starting with 5.0.0. This 5.0.0 release may initially remain on the existing BlueMapWebChat listing so 4.7.0 installations can discover the bridge upgrade. If this listing is later retired because a seamless rename is unavailable, the replacement KOKOTO WebChat address will be placed at the top of this page before future releases move there.

Existing BMWC 4.x server data/config can be imported by KWC 5.0.0; the original BMWC data directory is left untouched as a migration/rollback source.

KOKOTO WebChat is a server-side Minecraft web chat for Bukkit/Paper/Spigot 1.18–26.2 (Java 17), Fabric exact targets 1.18.2–26.2, NeoForge exact targets 1.20.2–26.2, and Forge exact targets 1.18.2–26.2; mod-loader targets select Java 17/21/25 by Minecraft version. It can run as a standalone web chat or embed into supported map frontends including BlueMap, squaremap, Dynmap, Pl3xMap, LiveAtlas, uNmINeD, and Minecraft Overviewer. No client mod is required for the core chat features.

What's new in 5.0.0

5.0.0 is the largest KWC/BMWC architecture expansion so far:

• Bukkit/Paper/Spigot + Fabric + NeoForge + Forge release matrix: 1 Bukkit artifact plus 16 Fabric, 12 NeoForge and 16 Forge exact-target artifacts
• Map-independent deployment across BlueMap, squaremap, Dynmap, Pl3xMap, LiveAtlas, uNmINeD, Minecraft Overviewer, and a standalone web client
• Unicode-aware moderation/content filtering with Block/Mask/Replace, bulk word lists, custom rules, anti-evasion matching and Web Admin testing
• Per-account UI profiles and notification preferences, improved desktop/mobile notification separation, and administrator Discord keyword alerts
• Long-history/rich-media scroll stability using one deterministic virtual-scroll lifecycle for images, GIFs, video, audio, YouTube/iframes and link previews
• Expanded multi-server DM/group/relay reliability, delivery/read state, exact server+UUID routing and retry-safe persistence
• ImageEmojis-Bero and SimpleNicks-Bero deployment guides for shared emoji assets/resource-pack hosting and nickname display integration on Bukkit/Paper-family servers

Highlights

• 5.0.0 multi-platform architecture: shared behavior lives in kwc-core; Bukkit, Fabric, NeoForge, and Forge provide loader-specific server integration while reusing the same core and frontend/adapters
• Two-way game ↔ web chat with linked Minecraft accounts and optional guest chat
• BlueMap addon + standalone page with dark/light/high-contrast UI, PIP, draggable/resizable windows, search, replies, pins, and virtual scrolling
• 1:1 direct messages with local and cross-server recipients, exact server+UUID routing, retry-safe delivery, unread/read state, and shared game/web threads
• Group chat rooms with public/private visibility, invitations, passwords, retention limits, unread counts, delivery retry protection, and member management
• Signed server-to-server relay for multi-server communities, including full-mesh or hub layouts, HMAC authentication, hop limits, deduplication, server badges, and source filters
• DiscordSRV integration plus Discord media caching and optional emoji-link augmentation
• Uploads and rich previews for images, video, audio, YouTube/Shorts, with optional TikTok and X/Twitter embeds
• Deterministic long-history virtual scrolling across images, GIFs, video, audio, YouTube/iframes and link previews, with scroll-anchor correction as media sizes settle
• Unicode-aware content filtering for public/group chat and optional DM with Block/Mask/Replace, bulk word lists, custom rules, anti-evasion matching and Web Admin testing
• Custom emoji management with multi-file administrator upload, plus optional ImageEmojis-Bero Bukkit/Paper integration using the same plugins/KOKOTO-WebChat/emojis tree; its resource-pack HTTP port remains a separate client-facing service
• SimpleNicks-Bero nickname integration on Bukkit/Paper-family servers through player-display.mode: "display-name", while KWC retains the real linked account identity
• Configurable message tokens such as :enter: / :newline: / :tab: with administrator-localizable aliases and printable custom substitutions
• Web Push / keyword notifications and administrator update notifications
• Per-account visual UI profiles plus account-synced keyword/notification preferences for signed-in users; device-local window state and Push endpoints stay local
• Administrator Discord keyword alerts with KWC-owned matching/deduplication and DiscordSRV logical-channel selection
• Administration and moderation tools for message hiding, pins, guest/IP mutes, session revocation, custom emoji management, and private-chat metadata
• Optional read-only DM and group-chat body audit for explicitly allowlisted super administrators; both are disabled by default and every audit page read is logged
• Built-in UI languages: English, Korean, Japanese, Simplified Chinese

Private messaging and delivery reliability

Cross-server DM targets are identified by server ID + player UUID, so a local player cannot be confused with a same-name player on another server. Remote messages stay pending until the destination confirms storage. Failed or uncertain sends can be retried with persistent relay/client message IDs without duplicating sender or receiver records.

DM and group-chat message state is shown compactly beside the timestamp. Normal successful delivery is silent; pending or failed delivery is shown only when needed. DM messages use a short unread label until the recipient reads them, then show ✓. Group messages show the number of recipients who have not read the message and change to ✓ when everyone has read it.

Multi-server relay

The optional relay supports public chat and private DM routing between multiple KOKOTO WebChat servers. Relay requests are HMAC-SHA256 signed and include replay protection, timestamp validation, relay-ID deduplication, hop limits, and origin tracking. Direct and hub topologies are supported.

For cross-server DM delivery/read acknowledgements, every participating server should run the same current KOKOTO WebChat release.

Administrator private-chat audit

Private message bodies are not automatically exposed to normal administrators. Optional audit access requires an exact Minecraft name/UUID in private-chat-super-admins and the corresponding feature switch:

direct-message:
  admin-audit:
    enabled: false

group-chat:
  admin-audit:
    enabled: false

Audit views are read-only. Group audit does not join the room or affect read/unread state. Every audit page read records the actor and pagination metadata without copying message bodies into the audit log.

Deployment

Fresh configurations start with the plugin master switch disabled so operators can review storage, authentication, uploads, retention, and web exposure before enabling it. During migration, the bundled config.yml is the only template: KWC creates a fresh current default and overlays existing operator values, so old comments/layout are replaced by the current bundled comments/layout. A fixed older-version config is backed up before reconstruction. <version>_auto_migration repeats this rebuild on startup/reload; exact <version> fixes the current-version config and prevents same-version rewriting. config-reference-<version>.yml is an administrator-readable exact default copy, not the migration source, and obsolete generated reference/migration files are cleaned up automatically. /kchat reload validates edited YAML before stopping live services; invalid YAML is rejected so the previous running configuration, UI language, and services remain active. Bundled UTF-8 starter filter-word lists for Korean, English, Japanese, and Simplified Chinese are initialized once when the starter-list marker is absent; existing or disabled files are preserved, and administrator deletions after initialization are not reversed.

For public deployments, placing BlueMap and KOKOTO WebChat behind HTTPS with Caddy or Nginx is recommended.

Optional integrations

• BlueMap (Bukkit plus BlueMapAPI on Fabric/NeoForge and Forge 26.1.2/26.2)
• squaremap and Dynmap filesystem web adapters
• Pl3xMap on Bukkit/Paper-family and Fabric
• LiveAtlas, uNmINeD, and Minecraft Overviewer static-web adapters
• DiscordSRV on Bukkit
• ImageEmojis-Bero on Bukkit/Paper-family servers (shared KWC emoji path + runtime glyph resolution); general ImageEmojis operation follows the upstream plugin documentation
• SimpleNicks-Bero on Bukkit/Paper-family servers through Bukkit display names; general SimpleNicks operation follows the upstream plugin documentation
• Web Push notifications
