Visual Representation: Posts Component Logic

Functionality Overview:

  • Import necessary dependencies and types from respective files.
  • Define the interface PostsProps which contains properties posts of type TypedPost[] and user of type TypedUser.
  • Create the Posts component that displays posts from a specific user.
  • Render UI components dynamically based on the data received.

Pseudocode Representation:

import { User as TypedUser, Post as TypedPost } from '../__generated__/graphql';
import { Link } from 'react-router-dom';
import { faker } from '@faker-js/faker';
import {
  Card,
  CardContent,
  CardMedia,
  Divider,
  Grid,
  Typography,
} from '@mui/material';

interface PostsProps {
  posts: TypedPost[] | null | undefined;
  user: TypedUser;
}

function Posts({ posts, user }: PostsProps) {
  Display "Posts from {user.name}" with Typography component.
  Add a Divider component for styling.

  If posts is not empty:
    Display posts within a Grid container with specified spacing and columns.
    Iterate over each post in posts:
      Render each post within a Grid item using Card, CardContent, Typography, Link, and CardMedia components.

  return the constructed UI.
}

Key Elements:

  • Dependencies:
    • graphql, react-router-dom, @faker-js/faker, @mui/material
  • Component Structure:
    • Posts component
      • Props: posts, user
      • Renders:
        • Typography for user's name
        • Divider for styling
        • Grid for posts display
          • Card for each post
            • CardContent with post details
            • Link to individual post
            • CardMedia for post image

Flow of Logic:

  1. Import necessary packages and type definitions.
  2. Define the PostsProps interface to specify the structure of incoming props.
  3. Implement the Posts function component.
  4. Display header with user's name.
  5. Add a divider for styling.
  6. If there are posts:
    • Render a grid container with specified configurations.
    • Iterate over each post to display relevant information within a styled card.
  7. Return the constructed UI for rendering.
