Explore Shiki syntax highlighting, Mermaid diagrams, Sandpack playgrounds, and YouTube embeds. See 2025 features in action.

Welcome to our Phase 1 features demonstration! This post showcases the cutting-edge interactive components that make TechVue stand out in 2025.

Beautiful Code with Shiki

What is Shiki?

Shiki uses the same syntax highlighting engine as VS Code, providing pixel-perfect code display with accurate TypeScript support and beautiful themes.

TypeScript Example with Shiki

useAuth.ts

import { useState, useEffect } from 'react';

interface User {
id: string;
name: string;
email: string;
role: 'admin' | 'user';
}

export function useAuth() {
const [user, setUser] = useState<User | null>(null);
const [loading, setLoading] = useState(true);

useEffect(() => {
  async function loadUser() {
    try {
      const response = await fetch('/api/auth/me');
      const data = await response.json();
      setUser(data.user);
    } catch (error) {
      console.error('Auth error:', error);
    } finally {
      setLoading(false);
    }
  }

  loadUser();
}, []);

return { user, loading };
}

Python Example

data_processor.py

import pandas as pd
from typing import List, Dict

class DataProcessor:
  def __init__(self, file_path: str):
      self.data = pd.read_csv(file_path)

  def clean_data(self) -> pd.DataFrame:
      """Remove null values and duplicates"""
      return self.data.dropna().drop_duplicates()

  def get_statistics(self) -> Dict[str, float]:
      """Calculate basic statistics"""
      return {
          'mean': self.data.mean(),
          'median': self.data.median(),
          'std': self.data.std()
      }

React Counter Example

Interactive React Counter

import { useState } from 'react';
import './styles.css';

export default function App() {
const [count, setCount] = useState(0);
const [step, setStep] = useState(1);

return (
  <div className="app">
    <h1>Counter App</h1>
    <div className="counter-display">
      <h2>{count}</h2>
    </div>

    <div className="controls">
      <label>
        Step:
        <input
          type="number"
          value={step}
          onChange={(e) => setStep(Number(e.target.value))}
        />
      </label>
    </div>

    <div className="buttons">
      <button onClick={() => setCount(count - step)}>
        - {step}
      </button>
      <button onClick={() => setCount(0)}>
        Reset
      </button>
      <button onClick={() => setCount(count + step)}>
        + {step}
      </button>
    </div>
  </div>
);

Combining Features

Let's combine multiple components for a rich learning experience:

Step 1: Understand the Architecture

First, let's visualize how the components work together:

Step 2: Write Your Code

Use Shiki for beautiful syntax highlighting:

MyComponent.jsx

export function MyComponent({ data }) {
return (
  <div className="component">
    <h2>{data.title}</h2>
    <p>{data.description}</p>
  </div>
);
}

Step 3: Test Interactively

Try it live in the playground:

Pro Tip

Use Sandpack for live demos that readers can edit and test immediately!

Step 4: Learn More

Watch tutorial videos and explore documentation to deepen your understanding.

Performance Benefits

Before vs After Phase 1

❌ Before

Plain text code blocks
Static images for diagrams
External CodePen embeds
Heavy YouTube iframe embeds
No syntax highlighting
Poor mobile experience

✅ After Phase 1

Beautiful Shiki highlighting
Interactive Mermaid diagrams
Built-in Sandpack playgrounds
Optimized YouTube embeds
Server-side rendering
Responsive on all devices

Best Practices

Use ShikiCodeBlock for all code examples in your blog posts. It provides VS Code-quality highlighting and supports all major programming languages.

Perfect for flowcharts, sequence diagrams, architecture diagrams, and any visual representation of systems or processes.

Use Sandpack playgrounds when you want readers to interact with code examples. Great for tutorials, documentation, and educational content.

Embed videos for tutorials, demos, or supplementary content. The lite embed ensures fast page loads.

Conclusion

These Phase 1 features transform TechVue into a modern, interactive platform that provides an exceptional reading and learning experience. Each component is optimized for performance, accessibility, and user engagement.

What's Next?

Stay tuned for Phase 2 featuring full-text search, image galleries, and newsletter integration!
