Caching Development Tutorials, Guides & Insights

Compare query times before and after optimization to measure improvement.

• Use eager loading to eliminate N+1 issues.
• Process large datasets with chunking or lazy collections to avoid memory exhaustion.
• Optimize queries with indexes, caching, and query restructuring.
• Test and monitor queries regularly to ensure scalability and performance.

@app.after_request
def after_request(response):
    if response.content_type == 'text/html; charset=utf-8':
        response.set_data(minify(response.get_data(as_text=True)))

Note: Actual push functionality requires a server-side setup using libraries like web-push in Node.js.

PWAs can leverage various modern web APIs to enhance functionality. Here are a few examples:
