Logging

Configure logging and debug mode.

Debug Mode

# Verbose output - all headers, body, time
app = FastHTTP(debug=True)

# Minimal output - status and time only
app = FastHTTP(debug=False)

Debug Output

When debug=True:

DEBUG   | fasthttp    | GET https://api.example.com/data | headers={'User-Agent': 'fasthttp/0.1.0'}
DEBUG   | fasthttp    | 200 | headers={'Content-Type': 'application/json'}
INFO    | fasthttp    | GET https://api.example.com/data 200 150.23ms

When debug=False:

INFO    | fasthttp    | GET https://api.example.com/data 200 150.23ms

What Debug Shows

debug=True

• Request and response headers
• Request and response body
• Execution time of each request
• Full URL with parameters

debug=False

• Only status code
• Execution time

Example

from fasthttp import FastHTTP

app = FastHTTP(debug=True)


@app.get(url="https://api.example.com/data")
async def handler(resp):
    return resp.json()


app.run()

Logging Best Practices

• Use debug=True during development
• Use debug=False in production
• Check logs regularly for errors
• Monitor request times
