📝 Walkthrough

Walkthrough

This PR introduces a complete conversation and messaging system by creating database migrations for conversations, messages, and user participation tracking, establishing corresponding Sequelize models with proper relationships, updating service configurations for conversation and message handling, and refactoring hooks to support state management via date fields instead of boolean flags.

Changes

Cohort / File(s)	Summary
Database Migrations migrations/20260103212326-create-conversations-table.js, migrations/20260103212327-create-messages-table.js, migrations/20260103212328-create-conversation-users-table.js	Creates three new PostgreSQL tables: conversations with type ENUM and metadata; messages with foreign keys to users and conversations; conversation_users as a junction table for many-to-many relationships. All include indexes on foreign keys and type columns for query performance.
Database Models - Core Entities src/database/conversation.ts, src/database/message.ts, src/database/conversation-user.ts	Refactors Conversation model to remove message-count logic and add group metadata fields (groupName, groupDescription, groupPicture); replaces Message boolean state fields (read, received) with date-based fields (readDate, receivedDate) and renames senderId to userId; introduces ConversationUser join table model with composite primary key and BelongsTo associations.
Database Model Updates src/database/user.ts, src/database/index.ts	Adds coverPicture column and HasMany association to User model; uncomments and exports previously disabled Message, Conversation, and ConversationUser models from the database index.
Hooks Infrastructure src/Hooks/Refetch.ts, src/Hooks/NestedPath.ts, src/Hooks/index.ts	Introduces new Refetch hook factory for fetching updated records after mutations; adds explicit return type annotation to NestedPath hook; exports refetch to public API.
Service Hooks - Message Handling src/services/message/hooks/AdjustReadAndReceivedDate.ts, src/services/message/hooks/addSender.ts, src/services/message/hooks/includeSenderAndConversation.ts, src/services/message/hooks/incrementDecrementMessageInConversation.ts, src/services/message/hooks/publishMessage.ts, src/services/message/hooks/index.ts	Simplifies read/delivered state updates to set date fields; renames senderId to userId in AutoAssign; changes User association alias from 'sender' to 'user' and removes Media association; reimplements message count adjustment with direct conversation service patching; removes publishMessage hook and its export.
Message Service src/services/message/message.class.ts, src/services/message/message.hooks.ts	Refactors create method to use base Feathers service; adds NestedPath to before.find and before.create; replaces PublishMessage with refetch hook; updates before.patch to use single hook instead of array.
Conversation Service src/services/conversation/conversation.service.ts, src/services/conversation/conversation.hooks.ts, src/services/conversation/hook/filterConversation.ts, src/services/conversation/hook/getUnreadMessage.ts, src/services/conversation/hook/limitConversationToTalkersOnly.ts, src/services/conversation/hook/limitDirectConversation.ts	Configures conversation service with dedicated Model and Message nested service; updates hook configuration to use refetch and AddTalker in error handlers; converts all SQL queries to snake_case naming conventions; refactors direct conversation creation to check for existing user pairs and adds self-conversation validation.
Conversation Hook Updates src/Hooks/AddTalker.ts	Changes ConversationUser model reference, updates field names (userId, conversationId), adds conditional amountOfPeople update only for group conversations, and adjusts error handling to rethrow as GeneralError.
Friendship Service src/services/friendships/friendship.class.ts, src/services/friendships/friendship.hook.ts, src/services/friendships/friendship.service.ts	Adds find method to filter accepted friendships with proper user exclusion; reorganizes before hooks to run AddTargetUser on find and create; adds after.patch hook for friend request acceptance notifications; updates publish notification logic to use usersToNotify array.
Service Initialization src/services/index.ts	Uncomments and enables conversation service import and initialization in the services array.
Code Cleanup src/services/users/users.class.ts	Removes commented-out Cognito-based create/get method scaffolding.

Poem

🐰 Conversations bloom like clover in spring,
Messages hop from user to user,
Database tables dance in formation,
With date-based states (no more booleans, hooray!),
A messaging burrow, nested and true! 🌿✨
