SRP-compliant Approach: PostController

post.controller.ts

import { Controller, Get, Post, Body} from '@nestjs/common';
import { PostsService } from './posts.service';
import { CreatePostDto } from './dto/create-post.dto';

@Controller('posts')
export class PostsController {
  constructor(private readonly postsService: PostsService) {}

  // endpoint for create new post
  @Post()
  createPost(@Body() createPostDto: CreatePostDto) {
    return this.postsService.createPost(createPostDto);
  }

  // endpoint for retrieve all posts
  @Get()
  findAllPosts() {
    return this.postsService.findAllPosts();
  }

}
