Prompt:

My Typescript React Material UI Blogs and Posts app features a number of posts on the home page. These are rendered using Material UI's Card component. I want to implement a post detail page which the user will navigate to when they click on the Card for a post. How do you suggest I implement this to take maximum advantage of Material UI

Response:

Thought for a few seconds

For the user's request on creating a post detail page with TypeScript, React, and MUI, I'll focus on using React Router for navigation and MUI components like Card, CardMedia, Typography, and Breadcrumbs. I will integrate hooks for data fetching, add responsive design features, and show transitions like Fade. I'll also use MUI Skeleton for loading states and manage accessibility and SEO

Done

Nice — this is a great place to use the best of Material UI (MUI). I’ll give a practical, modern pattern you can drop into a TypeScript React app: router routes, accessible navigation from the Card, a rich MUI-based detail layout (hero image, meta, actions, content), loading states (Skeleton), transitions, plus a few UX options (modal/detail route, prefetching). Code snippets show concrete component/sx usage so it feels idiomatic to MUI.

Key ideas (short)

  • Route-based detail page: use React Router (/posts/:postId) and useParams to load the single post.
  • Make the Card clickable with MUI’s CardActionArea or by making any MUI control use react-router-dom’s Link via the component prop.
  • Use MUI layout primitives (Container, Grid, Paper, Stack, Box) to compose a responsive, readable detail page.
  • Hero area: CardMedia or Box component="img" for the large header image + Typography overlay.
  • Actions & meta with IconButton, Chip, Avatar, Breadcrumbs.
  • Loading / skeleton: MUI Skeleton while fetching.
  • Optional modal/detail-in-drawer: You can render the detail either as a dedicated route or as a modal/dialog on top of the list (both supported by React Router patterns).
  • Progressive UX: prefetch when hovering over card, lazy-load detail component, or use React Query.

Example code (TypeScript + MUI + react-router-dom)

These are minimal working snippets; adapt to your fetching layer (fetch / axios / React Query).

1) PostCard.tsx — clickable card that navigates

// PostCard.tsx
import React from "react";
import { Card, CardActionArea, CardContent, CardMedia, Typography, Avatar, Stack, Box } from "@mui/material";
import { Link as RouterLink } from "react-router-dom";

type PostSummary = {
  id: string;
  title: string;
  excerpt: string;
  coverUrl?: string;
  authorName?: string;
  authorAvatar?: string;
  publishedAt?: string; // ISO
};

export default function PostCard({ post }: { post: PostSummary }) {
  return (
    <Card elevation={3} sx={{ height: "100%", display: "flex", flexDirection: "column" }}>
      {/* Make entire card a link using CardActionArea + react-router Link */}
      <CardActionArea
        component={RouterLink}
        to={`/posts/${post.id}`}
        sx={{ flexGrow: 1, alignItems: "stretch", display: "flex", flexDirection: "column", textDecoration: "none" }}
      >
        {post.coverUrl && (
          <CardMedia
            component="img"
            image={post.coverUrl}
            alt={post.title}
            sx={{ width: "100%", height: 160, objectFit: "cover" }}
          />
        )}
        <CardContent sx={{ flexGrow: 1 }}>
          <Typography variant="h6" gutterBottom noWrap>
            {post.title}
          </Typography>
          <Typography variant="body2" color="text.secondary" noWrap>
            {post.excerpt}
          </Typography>

          <Stack direction="row" spacing={1} alignItems="center" sx={{ mt: 2 }}>
            <Avatar src={post.authorAvatar} alt={post.authorName} sx={{ width: 28, height: 28 }} />
            <Box>
              <Typography variant="caption" display="block">{post.authorName}</Typography>
              {post.publishedAt && <Typography variant="caption" color="text.secondary">{new Date(post.publishedAt).toLocaleDateString()}</Typography>}
            </Box>
          </Stack>
        </CardContent>
      </CardActionArea>
    </Card>
  );
}

Notes

  • component={RouterLink} + to is the recommended MUI pattern for links.
  • CardActionArea gives correct hover/focus styles and keyboard accessibility.

2) AppRoutes.tsx — route config (React Router v6 example)

// AppRoutes.tsx
import React, { Suspense, lazy } from "react";
import { Routes, Route } from "react-router-dom";
import PostsList from "./PostsList";
const PostDetail = lazy(() => import("./PostDetail")); // code-splitting

export default function AppRoutes() {
  return (
    <Routes>
      <Route path="/" element={<PostsList />} />
      <Route
        path="/posts/:postId"
        element={
          <Suspense fallback={<div>Loading...</div>}>
            <PostDetail />
          </Suspense>
        }
      />
    </Routes>
  );
}

3) PostDetail.tsx — MUI-styled detail page with Skeleton

// PostDetail.tsx
import React, { useEffect, useState } from "react";
import { useParams, Link as RouterLink, useNavigate } from "react-router-dom";
import {
  Container, Box, Typography, IconButton, Avatar, Stack, Chip, Breadcrumbs, Link, Paper, Divider, Skeleton, Tooltip
} from "@mui/material";
import ArrowBackIcon from "@mui/icons-material/ArrowBack";
import FavoriteBorderIcon from "@mui/icons-material/FavoriteBorder";
import ShareIcon from "@mui/icons-material/Share";

type Post = {
  id: string;
  title: string;
  content: string;
  coverUrl?: string;
  authorName?: string;
  authorAvatar?: string;
  tags?: string[];
  publishedAt?: string;
};

export default function PostDetail() {
  const { postId } = useParams<{ postId: string }>();
  const navigate = useNavigate();
  const [post, setPost] = useState<Post | null>(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    if (!postId) return;
    setLoading(true);
    // Replace with your fetch / react-query hook
    fetch(`/api/posts/${postId}`)
      .then((r) => r.json())
      .then((data: Post) => {
        setPost(data);
      })
      .catch(() => {
        // handle error (show 404 or toast)
      })
      .finally(() => setLoading(false));
  }, [postId]);

  return (
    <Container maxWidth="md" sx={{ py: 4 }}>
      <Stack direction="row" alignItems="center" spacing={2} sx={{ mb: 2 }}>
        <IconButton onClick={() => navigate(-1)} aria-label="back">
          <ArrowBackIcon />
        </IconButton>

        <Breadcrumbs aria-label="breadcrumb">
          <Link component={RouterLink} to="/">Home</Link>
          <Typography color="text.primary">{loading ? <Skeleton width={120} /> : post?.title}</Typography>
        </Breadcrumbs>
      </Stack>

      <Paper elevation={0} sx={{ overflow: "hidden", mb: 3 }}>
        {/* Hero image */}
        {loading ? (
          <Skeleton variant="rectangular" height={300} />
        ) : post?.coverUrl ? (
          <Box component="img" src={post.coverUrl} alt={post.title} sx={{ width: "100%", height: 320, objectFit: "cover" }} />
        ) : (
          <Box sx={{ width: "100%", height: 160, bgcolor: "grey.200" }} />
        )}

        <Box sx={{ p: 3 }}>
          <Stack direction="row" justifyContent="space-between" alignItems="flex-start" spacing={2}>
            <Box>
              <Typography variant="h4" gutterBottom>{loading ? <Skeleton width={300} /> : post?.title}</Typography>
              <Stack direction="row" spacing={1} alignItems="center">
                <Avatar src={post?.authorAvatar} alt={post?.authorName} />
                <Box>
                  <Typography variant="subtitle2">{post?.authorName}</Typography>
                  {post?.publishedAt && (
                    <Typography variant="caption" color="text.secondary">{new Date(post.publishedAt).toLocaleDateString()}</Typography>
                  )}
                </Box>
              </Stack>
            </Box>

            <Stack direction="row" spacing={1}>
              <Tooltip title="Like">
                <IconButton><FavoriteBorderIcon /></IconButton>
              </Tooltip>
              <Tooltip title="Share">
                <IconButton><ShareIcon /></IconButton>
              </Tooltip>
            </Stack>
          </Stack>

          <Divider sx={{ my: 2 }} />

          {/* Tags */}
          <Stack direction="row" spacing={1} sx={{ mb: 2 }}>
            {loading ? (
              <>
                <Skeleton width={60} height={28} />
                <Skeleton width={60} height={28} />
              </>
            ) : (
              post?.tags?.map(tag => <Chip key={tag} label={tag} size="small" />)
            )}
          </Stack>

          {/* Content */}
          <Box sx={{ typography: "body1", "& img": { maxWidth: "100%" } }}>
            {loading ? (
              <>
                <Skeleton height={24} width="80%" />
                <Skeleton height={24} width="95%" />
                <Skeleton height={24} width="90%" />
                <Skeleton height={24} width="85%" />
              </>
            ) : (
              // If content is HTML, be cautious and sanitize or use a safe renderer.
              <div dangerouslySetInnerHTML={{ __html: post?.content ?? "" }} />
            )}
          </Box>
        </Box>
      </Paper>
    </Container>
  );
}

Notes

  • Use Skeleton for pleasant perceived performance.
  • If content is HTML, sanitize before rendering. Consider DOMPurify.
  • Breadcrumbs + back button improve discoverability and navigation.

Optional UX enhancements (recommended)

Modal or Drawer detail (quick peek)

Render the detail page as a route and as a modal on top of the list. React Router supports this pattern: when navigating from the list, pass location state so you can render the detail Route as a Dialog or Drawer while keeping the list in the background (good mobile UX).

Prefetching

  • On Card hover or focus, prefetch the detail data (or use React Query + queryClient.prefetchQuery) so the detail loads instantly.

Use React Query or SWR

  • For caching, background refetching, and prefetching. Works well with Suspense.

Accessibility

  • Keep buttons inside CardActionArea minimal to avoid nested interactive elements that conflict with the CardActionArea click. If you must have buttons inside, stop propagation or use separate controls outside the CardActionArea.

Transitions/animations

  • Use Fade, Grow, or Slide from MUI when showing/hiding the hero or comments to give a polished feel.

SEO & SSR

  • If you need SEO for posts, prefer server-side rendering (Next.js) or pre-rendering for each post route so social cards and crawlers get the content.

File/architecture suggestions

  • components/PostCard.tsx
  • pages/PostsList.tsx
  • pages/PostDetail.tsx
  • api/posts.ts — centralize fetch calls (and adapt easily to React Query)
  • routes.tsx or AppRoutes.tsx — route config, lazy loaded detail page

Final checklist before shipping

  • Cards are keyboard focusable and navigate on Enter/Space.
  • Images have alt attributes.
  • HTML content is sanitized.
  • Prefetch enabled for smooth transitions.
  • Mobile layout tested (hero image size, back behavior).
  • Loading UI (Skeleton) implemented.
  • Consider dialog/drawer modal UX for quick views.

If you like, I can:

  • Convert the snippets to fit your data-fetching setup (axios / React Query).
  • Show the modal/via-route pattern for detail-as-dialog (small code + routing state).
  • Add a prefetch example using React Query.

Restructuring Card Component

Done

Nice — thanks for sharing the component. Below I’ll give a focused, practical upgrade that:

  • makes the whole card navigate to a post detail route (/posts/:id) in an accessible way using MUI + react-router-dom (CardActionArea + component={RouterLink}),
  • keeps your existing focus/blur behavior,
  • recommends small fixes (return null, not ''), and
  • shows an optional prefetch pattern (React Query) and how to handle interactive children (like links or buttons inside Author) so they don’t conflict with the card link.

Key changes I recommend

  1. Wrap content in CardActionArea with component={RouterLink} and to={/posts/${data.id}}. This keeps MUI accessibility and keyboard behavior.
  2. Don’t return an empty string when data is missing — return null.
  3. Avoid nested interactive controls inside CardActionArea (e.g., if Author contains a link or button) — either place them outside the action area or stop event propagation inside those controls.
  4. Prefetch on hover (optional) using React Query or your fetch layer so clicking feels instant.
  5. Add aria-disabled / CSS class for non-matching search so it’s clear visually and to assistive tech that the card is not actionable.
  6. Make TypeScript explicit about id existence (data.id), or compute link only when present.

Updated StyledCardItem.tsx 

import React from 'react';
import { Typography, CardMedia, CardActionArea, Box } from '@mui/material';
import { Link as RouterLink } from 'react-router-dom';
import StyledCard from './StyledCard';
import StyledCardContent from './StyledCardContent';

import Author from './Author';
import type { BlogPost } from '../types/BlogPost';

  onFocus: (index: number) => void;
  onBlur: () => void;
  showImage?: boolean;
  selectedTag: string | null;

      </Box>

export default StyledCardItem;

Prefetch example (React Query)

If you use React Query, do something like this in a parent or provide onPrefetch:

// parent component
import { useQueryClient } from '@tanstack/react-query';
const queryClient = useQueryClient();

const prefetchPost = (id: string) => {
  queryClient.prefetchQuery(['post', id], () => fetch(`/api/posts/${id}`).then(r => r.json()));
};

// pass to card
<StyledCardItem onPrefetch={prefetchPost} ... />

Call prefetchPost on onMouseEnter or onFocus to warm the cache.

Modal / route overlay pattern (optional UX)

If you want a modal preview when navigating from the list, use React Router location state:

  • When linking from the list, pass state: { background: location }.
  • In your routes, check location.state?.background and render PostDetail as a Dialog while keeping the list Underneath.
    This makes a nice quick-preview UX, especially on desktop.

Other small tips

  • Keyboard behavior: CardActionArea handles Enter/Space. Ensure no inner focusable element steals activation unless intended.
  • Alt text: Make sure data.img alt text is descriptive.
  • Sanitize content: If your detail renders HTML, sanitize server-side or client-side (DOMPurify).
  • Accessibility: Use aria-disabled for visually-disabled cards and ensure tabIndex behavior still works how you want.
  • Testing: Check with keyboard-only navigation and a screen reader to ensure the card is announced as a link.

If you want I can:

  • Convert Author to show how to stopPropagation() for nested links, or
  • Show the route-as-modal implementation with the React Router code snippet, or
  • Update your PostDetail page example to match your BlogPost type.

Which would help most next?

Prompt:

This is the definition for a BlogPost: import { AuthorData } from "./Author";

export interface BlogPost { img: string; tag: string; title: string; description: string; authors: AuthorData[]; }

Response:

Thought for a couple of seconds

It looks like I need to adapt some earlier code to a new BlogPost type. The key issue is the missing id and publishedAt fields—earlier, the post.id was used, but now BlogPost doesn’t have id. I could suggest adding the id field

Done

Thanks — that BlogPost type explains why earlier examples referenced data.id (you don’t have an id/slug yet). You have two clean choices:

  • Preferred: add a unique identifier to your BlogPost (recommended: id: string or slug: string).
  • Fallback: derive a slug from the title at render-time (works, but fragile — titles can collide or change).

Below I’ll show:

  1. a recommended change to the BlogPost type,
  2. an updated StyledCardItem that uses the id/slug (with a safe fallback slugify),
  3. a quick Author note (stop nested link clicks from navigating),
  4. a short migration checklist.
  1. Recommended BlogPost type

Add an id or slug. id is simpler (UUID, numeric id from DB). slug is friendly (used in URLs). Example:

// types/BlogPost.ts
import { AuthorData } from "./Author";

export interface BlogPost {
  id: string;           // Unique identifier (UUID / DB id)
  slug?: string;        // Optional: human-friendly url (post.slug || slugify(title))
  img: string;
  tag: string;
  title: string;
  description: string;
  authors: AuthorData[];
  // optional extras:
  // publishedAt?: string;
  // content?: string; 
}

Why: React Router routes like /posts/:id or /posts/:slug need a stable unique value. Using title directly is brittle.

  1. Updated StyledCardItem (uses id/slug, with fallback slugify)

This keeps your current props and gracefully falls back to a slug derived from title only if no id/slug is present.

import React from 'react';
import { Typography, CardMedia, CardActionArea, Box } from '@mui/material';
import { Link as RouterLink } from 'react-router-dom';
import StyledCard from './StyledCard';
import StyledCardContent from './StyledCardContent';
import StyledTypography from './StyledTypography';
import Author from './Author';
import type { BlogPost } from '../types/BlogPost';

interface StyledCardItemProps {
  data?: BlogPost;
  index: number;
  focusedIndex: number | null;
  onFocus: (index: number) => void;
  onBlur: () => void;
  showImage?: boolean;
  selectedTag: string | null;
  searchTerm: string | null;
  onPrefetch?: (postKey: string) => void; // key could be id or slug
}

/** Simple slugify — good as a fallback only. */
const slugify = (s: string) =>
  s
    .toLowerCase()
    .trim()
    .replace(/[\s\W-]+/g, '-')     // collapse spaces/non-word to dash
    .replace(/^-+|-+$/g, '');      // strip leading/trailing dash

const StyledCardItem: React.FC<StyledCardItemProps> = ({
  data,
  index,
  focusedIndex,
  onFocus,
  onBlur,
  showImage = true,
  selectedTag,
  searchTerm,
  onPrefetch,
}) => {
  if (!data) return null;

  const matchesSearch =
    !searchTerm ||
    data.title.toLowerCase().includes(searchTerm.toLowerCase()) ||
    data.description.toLowerCase().includes(searchTerm.toLowerCase());

  const normalizedSelected = selectedTag?.trim().toLowerCase() ?? null;

  // Prefer id, then slug, then fallback to derived slug.
  const postKey = data.id ?? data.slug ?? slugify(data.title);
  const toRoute = `/posts/${encodeURIComponent(postKey)}`;

  const handleMouseEnter = () => {
    if (onPrefetch && postKey) onPrefetch(postKey);
  };

  return (
    <StyledCard
      variant="outlined"
      onFocus={() => onFocus(index)}
      onBlur={onBlur}
      tabIndex={0}
      className={`${focusedIndex === index ? 'Mui-focused' : ''} ${!matchesSearch ? 'disabled-card' : ''}`}
      sx={{ height: '100%' }}
      aria-disabled={!matchesSearch}
    >
      <CardActionArea
        component={RouterLink}
        to={toRoute}
        onMouseEnter={handleMouseEnter}
        sx={{ display: 'flex', flexDirection: 'column', alignItems: 'stretch', textDecoration: 'none' }}
      >
        {showImage && data.img && (
          <CardMedia
            component="img"
            alt={data.title}
            image={data.img}
            sx={{
              aspectRatio: '16 / 9',
              borderBottom: '1px solid',
              borderColor: 'divider',
            }}
          />
        )}

        <StyledCardContent>
          <Typography gutterBottom variant="caption" component="div" aria-label="tags">
            {(() => {
              const raw = data.tag ?? '';
              const tags = raw
                .split(',')
                .map(t => t.trim())
                .filter(Boolean);

              tags.sort((a, b) => a.localeCompare(b, undefined, { sensitivity: 'base', numeric: true }));

              return tags.length === 0 ? (
                <span>-</span>
              ) : (
                tags.map((tag, idx) => {
                  const isMatch = normalizedSelected !== null && tag.toLowerCase() === normalizedSelected;
                  return (
                    <span key={`${tag}-${idx}`}>
                      <span style={{ fontWeight: isMatch ? 700 : 400 }}>{tag}</span>
                      {idx < tags.length - 1 ? ', ' : ''}
                    </span>
                  );
                })
              );
            })()}
          </Typography>

          <Typography gutterBottom variant="h6" component="div">
            {data.title}
          </Typography>

          <StyledTypography variant="body2" color="text.secondary" gutterBottom>
            {data.description}
          </StyledTypography>
        </StyledCardContent>
      </CardActionArea>

      {/* Keep Author outside the CardActionArea if it contains interactive controls */}
      <Box sx={{ px: 2, py: 1 }}>
        <Author authors={data.authors} />
      </Box>
    </StyledCard>
  );
};

export default StyledCardItem;

Notes:

  • postKey is the canonical identifier used for the route and prefetch key.
  • slugify(...) is only a fallback. If two posts share the same derived slug you’ll have collisions — so prefer explicit id or slug.
  • encodeURIComponent ensures safe URL segments.
  1. Author component: stop nested clicks if it contains links/buttons

If Author renders <a> or <button> elements (profile link, follow button), ensure those children don’t cause the card link to trigger by stopping propagation:

// inside Author.tsx (example for a link)
const handleAuthorLinkClick = (e: React.MouseEvent) => {
  e.stopPropagation(); // prevents CardActionArea navigation
  // (optionally) allow default link navigation if you render a normal <a href>
};

return (
  <a href={`/author/${author.id}`} onClick={handleAuthorLinkClick}>
    {author.name}
  </a>
);

Alternatively, render Author outside CardActionArea (as shown above) to avoid this entirely.

  1. Migration checklist
  • Update your data source (CMS, DB, JSON file) to include id or slug for each post.
  • Change type import BlogPost across your codebase. (Make id required if you rely on it everywhere.)
  • Update route: use /posts/:id or /posts/:slug and fetch by that key.
  • Prefetch: if using React Query, use the same key (['post', postKey]) for prefetch and fetch.
  • Test collisions if you allow derived slugs — better to prevent this by having unique slugs stored with each post.
  • SEO: if you use slugs for friendly URLs, include canonical tags on the detail page.

Quick decisions you can make now

  • If you control the data source: add id — fastest and safest.
  • If you want human-readable URLs: add slug (unique).
  • If you need a quick patch with minimal back-end changes: use the slugify fallback but plan to migrate to explicit ids/slugs soon.

If you want, I can:

  • Give the matching PostDetail route/component for :id or :slug.
  • Show how to prefetch with React Query using the postKey.
  • Provide a small script to convert your existing post files into id/slug (if your posts are markdown/JSON).

Which of those would you like next?

Prompt:

This is the updated BlogPost with a string id. Give me the code for the PostDetail page, StyledCard and tell me how to configure the route. This is how routes are currently configured in App.tsx: import * as React from 'react'; import CssBaseline from '@mui/material/CssBaseline'; import Container from '@mui/material/Container'; import AppTheme from './shared-theme/AppTheme'; import AppAppBar from './components/AppAppBar';

import Footer from './components/Footer'; import { BrowserRouter as Router, Routes, Route } from "react-router-dom"; import Home from './pages/Home'; import Features from './pages/Features'; import Testimonials from './pages/Testimonials'; import Highlights from './pages/Highlights'; import Pricing from './pages/Pricing'; import FAQ from './pages/FAQ'; import Blog from './pages/Blog'; import { BlogPostServiceProvider } from './services/blog-post-service/BlogPostServiceContext';

export default function App(props: { disableCustomTheme?: boolean }) { return ( <AppTheme {...props}> <Container maxWidth="lg" component="main" sx={{ display: 'flex', flexDirection: 'column', my: 16, gap: 4 }} > <Route path="/" element={} /> <Route path="/features" element={} /> <Route path="/testimonials" element={} /> <Route path="/highlights" element={} /> <Route path="/pricing" element={} /> <Route path="/faq" element={} /> <Route path="/blog" element={} />

); }

Response:

Got it! Here’s a clear, complete setup for:

  • your PostDetail page component (fetching by id from a service),
  • a minimal StyledCard (so you have it ready; you can adapt your current one),
  • and how to add the new route to your existing routes in App.tsx.
  1. PostDetail.tsx — Show single post by id ============================================

This example assumes you have some blogPostService (from your BlogPostServiceContext) with a method to fetch a post by id asynchronously.

// src/pages/PostDetail.tsx
import React, { useEffect, useState, useContext } from 'react';
import { useParams, Link as RouterLink } from 'react-router-dom';
import { Typography, Card, CardMedia, CardContent, Box, Button } from '@mui/material';
import { BlogPostServiceContext } from '../services/blog-post-service/BlogPostServiceContext';
import type { BlogPost } from '../types/BlogPost';

export default function PostDetail() {
  const { id } = useParams<{ id: string }>();
  const blogPostService = useContext(BlogPostServiceContext);
  const [post, setPost] = useState<BlogPost | null>(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState<string | null>(null);

  useEffect(() => {
    if (!id) {
      setError('No post id provided.');
      setLoading(false);
      return;
    }

    setLoading(true);
    blogPostService
      .getPostById(id)
      .then(data => {
        setPost(data);
        setLoading(false);
      })
      .catch(() => {
        setError('Post not found.');
        setLoading(false);
      });
  }, [id, blogPostService]);

  if (loading) {
    return <Typography>Loading post...</Typography>;
  }

  if (error) {
    return (
      <Box>
        <Typography color="error">{error}</Typography>
        <Button component={RouterLink} to="/blog" variant="outlined" sx={{ mt: 2 }}>
          Back to Blog
        </Button>
      </Box>
    );
  }

  if (!post) {
    return null; // Or a fallback UI
  }

  return (
    <Card sx={{ maxWidth: 800, mx: 'auto' }}>
      {post.img && (
        <CardMedia
          component="img"
          image={post.img}
          alt={post.title}
          sx={{ aspectRatio: '16 / 9' }}
        />
      )}
      <CardContent>
        <Typography variant="h4" component="h1" gutterBottom>
          {post.title}
        </Typography>
        <Typography variant="subtitle1" color="text.secondary" gutterBottom>
          Tags: {post.tag || '-'}
        </Typography>
        <Typography variant="body1" paragraph>
          {post.description}
        </Typography>
        {/* Add your Author component or any additional post details here */}
      </CardContent>
    </Card>
  );
}
  1. Minimal StyledCard for reference =====================================

Since you import StyledCard in your card item, here is a minimal example based on MUI's Card with some custom styles:

// src/components/StyledCard.tsx
import { styled } from '@mui/material/styles';
import Card from '@mui/material/Card';

const StyledCard = styled(Card)(({ theme }) => ({
  cursor: 'pointer',
  height: '100%',
  display: 'flex',
  flexDirection: 'column',
  '&.Mui-focused': {
    boxShadow: theme.shadows[6],
    outline: `2px solid ${theme.palette.primary.main}`,
  },
  '&.disabled-card': {
    pointerEvents: 'none',
    opacity: 0.5,
  },
}));

export default StyledCard;

You can customize styles to your liking — just ensure you keep cursor: pointer on clickable cards and style focus states for accessibility.

  1. How to configure the route in App.tsx ==========================================

Add the new route below your /blog route to catch URLs like /posts/:id:

// App.tsx (modified part)

import PostDetail from './pages/PostDetail'; // import the new page

// Inside your <Routes> in <Container>
<Routes>
  <Route path="/" element={<Home />} />
  <Route path="/features" element={<Features />} />
  <Route path="/testimonials" element={<Testimonials />} />
  <Route path="/highlights" element={<Highlights />} />
  <Route path="/pricing" element={<Pricing />} />
  <Route path="/faq" element={<FAQ />} />
  <Route path="/blog" element={<Blog />} />
  
  {/* New route for post details */}
  <Route path="/posts/:id" element={<PostDetail />} />
</Routes>

Summary of what happens:

  • User clicks a StyledCardItem (wrapped in CardActionArea linking to /posts/{id}).
  • React Router matches /posts/:id and renders your new PostDetail component.
  • PostDetail fetches the post by id from your service, then displays it.
  • User can navigate back to /blog using the provided button or browser controls.

If you want, I can also help you:

  • Create a BlogPostService mock or example implementation if you don’t have one.
  • Show how to prefetch post data on card hover/focus.
  • Add an Author block inside PostDetail (similar to your card).
  • Add loading skeletons or animations for better UX.
