<?php
// Example: Generating JSON-LD for a PHP function
function generateSchemaForFunction(string $functionName, string $description, array $parameters): string {
$schema = [
'@context' => 'https://schema.org',
'@type' => 'WebPage',
'name' => "Documentation for {$functionName}()",
'description' => $description,
'mainEntity' => [
'@type' => 'SoftwareSourceCode',
'name' => $functionName,
'description' => $description,
'programmingLanguage' => 'PHP',
'codeRepository' => 'https://github.com/your/repo', // Placeholder
'executableCode' => "function {$functionName}(" . implode(', ', array_keys($parameters)) . ") { ... }",
'parameter' => array_map(function($paramName, $paramDetails) {
return [
'@type' => 'HowToDirection',
'name' => $paramName,
'text' => $paramDetails['description'] ?? '',
'stepValue' => $paramDetails['type'] ?? 'mixed'
];
}, array_keys($parameters), $parameters)
]
];
return json_encode($schema, JSON_PRETTY_PRINT);
}
$params = [
'userId' => ['type' => 'int', 'description' => 'The ID of the user to retrieve.'],
'includeDetails' => ['type' => 'bool', 'description' => 'Whether to fetch detailed user information.']
];
echo generateSchemaForFunction('getUserProfile', 'Retrieves a user\'s profile information.', $params);
?>
2. Technical Content Keyword Difficulty Tool: A specialized tool that analyzes keyword difficulty specifically for technical terms, programming languages, frameworks, and niche software. It would go beyond generic SEO tools by understanding the context of developer search queries.
# Conceptual Python script for keyword difficulty analysis (simplified)
import requests
import json
def get_keyword_difficulty(keyword: str, api_key: str) -> dict:
# This is a placeholder. A real tool would integrate with SERP analysis APIs
# and potentially use NLP to understand technical context.
# Example: Analyzing search volume, competitor density for technical terms.
print(f"Analyzing difficulty for technical keyword: '{keyword}'")
# Simulate API call to a hypothetical technical SEO API
# url = f"https://api.techseo.com/v1/difficulty?keyword={keyword}&apiKey={api_key}"
# response = requests.get(url)
# data = response.json()
# Simulated data
simulated_data = {
"keyword": keyword,
"difficulty_score": 75, # Scale of 0-100
"search_volume": 1500,
"top_competitors": ["Stack Overflow", "GitHub", "Official Docs"],
"technical_relevance_score": 0.9
}
return simulated_data
# Example Usage
API_KEY = "YOUR_TECHSEO_API_KEY" # Replace with actual API key
keyword = "python async await tutorial"
difficulty_info = get_keyword_difficulty(keyword, API_KEY)
print(json.dumps(difficulty_info, indent=2))
3. Code Snippet Performance Analyzer: A tool that analyzes the performance implications of common code snippets across different languages and frameworks. It could provide insights into execution time, memory usage, and potential bottlenecks for developers.
4. API Documentation Link Checker: A service that continuously crawls technical portals and checks the validity and accessibility of all external and internal links within API documentation. Essential for maintaining the integrity of developer resources.
# Example Bash script using curl to check link status
URL="https://api.example.com/docs/v1/users"
STATUS_CODE=$(curl -Is "$URL" | head -n 1 | awk '{print $2}')
if [ "$STATUS_CODE" = "200" ]; then
echo "Link $URL is OK (Status: $STATUS_CODE)"
elif [ "$STATUS_CODE" = "404" ]; then
echo "Link $URL is Broken (Status: $STATUS_CODE)"
else
echo "Link $URL has unexpected status: $STATUS_CODE"
fi

B. E-commerce Technical Optimization
6. Shopify App Performance Auditor: Analyzes the impact of installed Shopify apps on site speed, Core Web Vitals, and overall user experience. Provides actionable recommendations for optimization or removal.
// Conceptual JavaScript for Shopify App Performance Audit (client-side)
function auditAppPerformance(appName) {
console.log(`Auditing performance for Shopify app: ${appName}`);
// Simulate checks for common performance impacts:
// 1. Script loading time & impact on LCP/FID
// 2. CSS file size & impact on CLS
// 3. Network requests initiated by the app
// 4. DOM element manipulation frequency
const scriptLoadTime = Math.random() * 500 + 100; // ms
const cssImpact = Math.random() * 0.2; // CLS impact score
const networkRequests = Math.floor(Math.random() * 10) + 1;
console.log(`- Script Load Time: ${scriptLoadTime.toFixed(2)}ms`);
console.log(`- CLS Impact Score: ${clsImpact.toFixed(2)}`);
console.log(`- Network Requests: ${networkRequests}`);
if (scriptLoadTime > 300 || cssImpact > 0.1 || networkRequests > 5) {
console.warn(`App "${appName}" may be negatively impacting performance. Consider optimization or removal.`);
} else {
console.log(`App "${appName}" appears to have minimal performance impact.`);
}
}
// Example Usage
auditAppPerformance("Awesome Product Reviews App");
auditAppPerformance("Fast Checkout Button");

"""
Retrieve a specific item by its ID.
"""
item = Item(pk, f"Item {pk}", f"Description for item {pk}")
serializer = ItemSerializer(item)
return Response(serializer.data)
# In your Django urls.py, you would typically register this ViewSet with DefaultRouter
# from django.urls import path, include
# from rest_framework.routers import DefaultRouter
# from .views import ItemViewSet
#
# router = DefaultRouter()
# router.register(r'items', ItemViewSet, basename='item')
# urlpatterns = [
# path('api/', include(router.urls)),
# # ... other urls
# ]
# drf-yasg will then generate the /swagger/ endpoint automatically.

# Rule 1: Check for multi-stage builds
if ! grep -q "FROM .* AS" "$DOCKERFILE_PATH"; then
echo "[WARN] Consider using multi-stage builds to reduce final image size."
fi
# Rule 2: Check for apt-get update && apt-get install in the same RUN command
if grep -q "RUN apt-get update" "$DOCKERFILE_PATH" && grep -q "RUN .* apt-get install" "$DOCKERFILE_PATH"; then
# More sophisticated check needed to ensure they are in the SAME RUN command
echo "[INFO] Ensure 'apt-get update' and 'apt-get install' are in the same RUN command to leverage layer caching."
fi
# Rule 3: Check for unnecessary files copied before build dependencies are installed
# (Requires more complex parsing)
echo "[INFO] Review COPY commands. Ensure they are placed after build dependencies are installed if possible."
# Rule 4: Check for use of specific base images (e.g., alpine for smaller size)
if grep -q "FROM ubuntu" "$DOCKERFILE_PATH"; then
echo "[SUGGESTION] Consider using Alpine Linux as a base image for smaller footprints."

u.id,
u.username,
COUNT(o.id) AS order_count
FROM
users u
JOIN
orders o ON u.id = o.user_id
WHERE
u.created_at > '2023-01-01'
GROUP BY
u.id, u.username
ORDER BY
order_count DESC
LIMIT 10;
/*
Conceptual Analysis Output Interpretation:
- Look for Sequential Scans on large tables (users, orders) if indexes are missing.
- Check for high costs associated with HashAggregate or Sort operations.
- Identify inefficient joins (e.g., Nested Loop joins on large datasets).
- Suggest adding indexes on 'users.created_at' and 'orders.user_id'.
