Proposal: Implement Messaging API

[kakasoo]

Proposal for Messaging Feature

Overview

Implement an API for messaging between users. This feature will allow users to send and receive private messages within the platform.

Controller Implementation

The MessagesController will handle HTTP requests related to messages, providing endpoints to send and retrieve messages.

Service Implementation

The MessagesService will contain the business logic for sending and retrieving messages from the database.

DTOs and Models

• CreateMessageDto: Defines the data structure for creating a new message.

Example Code

Controller

import { Controller, Post, Body, Get, Param, UseGuards } from '@nestjs/common';
import { JwtGuard } from '../auth/guards/jwt.guard';
import { MessagesService } from '../providers/messages.service';
import { CreateMessageDto } from '../models/dtos/create-message.dto';

@UseGuards(JwtGuard)
@Controller('api/v1/messages')
export class MessagesController {
  constructor(private readonly messagesService: MessagesService) {}

  @Post()
  async sendMessage(@Body() createMessageDto: CreateMessageDto) {
    return this.messagesService.sendMessage(createMessageDto);
  }

  @Get(':userId')
  async getMessages(@Param('userId') userId: number) {
    return this.messagesService.getMessages(userId);
  }
}

Service

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { MessagesRepository } from '../models/repositories/messages.repository';
import { CreateMessageDto } from '../models/dtos/create-message.dto';

@Injectable()
export class MessagesService {
  constructor(
    @InjectRepository(MessagesRepository)
    private readonly messagesRepository: MessagesRepository,
  ) {}

  async sendMessage(createMessageDto: CreateMessageDto) {
    const message = this.messagesRepository.create(createMessageDto);
    return this.messagesRepository.save(message);
  }

  async getMessages(userId: number) {
    return this.messagesRepository.find({ where: { recipientId: userId } });
  }
}

DTO

export class CreateMessageDto {
  senderId: number;
  recipientId: number;
  content: string;
}

Conclusion

This proposal outlines the basic implementation for a messaging feature. Further enhancements could include real-time messaging and read receipts.
