```python
import logging.config
from typing import Tuple

import structlog
import uvicorn

from example.config import settings

shared_processors: Tuple[structlog.types.Processor, ...] = (
    structlog.contextvars.merge_contextvars,
    structlog.stdlib.add_logger_name,
    structlog.stdlib.add_log_level,
    structlog.processors.TimeStamper(fmt=""iso""),
)

logging_config = {
    ""version"": 1,
    ""disable_existing_loggers"": False,
    ""formatters"": {
        ""json"": {
            ""()"": structlog.stdlib.ProcessorFormatter,
            ""processor"": structlog.processors.JSONRenderer(),
            ""foreign_pre_chain"": shared_processors,
        },
        ""console"": {
            ""()"": structlog.stdlib.ProcessorFormatter,
            ""processor"": structlog.dev.ConsoleRenderer(),
            ""foreign_pre_chain"": shared_processors,

            ""level"": ""INFO"",

            ""formatter"": ""access"",
        },
        ""uvicorn.default"": {
            ""level"": ""INFO"",
            ""class"": ""logging.StreamHandler"",
            ""formatter"": ""default"",
        },
    },
    ""loggers"": {
        """": {""handlers"": [""default""], ""level"": ""INFO""},
        ""uvicorn.error"": {
            ""handlers"": [""default"" if not settings.debug else ""uvicorn.default""],
            ""level"": ""INFO"",
            ""propagate"": False,
        },
        ""uvicorn.access"": {
            ""handlers"": [""default"" if not settings.debug else ""uvicorn.access""],
            ""level"": ""INFO"",
            ""propagate"": False,
        },
    },
}


def setup_logging() -> None:
    structlog.configure(
        processors=[
            structlog.stdlib.filter_by_level,
            *shared_processors,
            structlog.stdlib.PositionalArgumentsFormatter(),
            structlog.processors.StackInfoRenderer(),
            structlog.processors.format_exc_info,
            structlog.stdlib.ProcessorFormatter.wrap_for_formatter,
        ],
        context_class=dict,
        logger_factory=structlog.stdlib.LoggerFactory(),
        wrapper_class=structlog.stdlib.AsyncBoundLogger,
        cache_logger_on_first_use=True,
    )
    logging.config.dictConfig(logging_config)
```

And then it'll be run on the startup event:
```python
@app.on_event(""startup"")
async def startup_event() -> None:
    setup_logging()
```

It depends on a setting called `debug` which controls if it should output the regular uvicorn logging or json. ","{""total_count"": 15, ""+1"": 7, ""-1"": 0, ""laugh"": 1, ""hooray"": 1, ""confused"": 0, ""heart"": 5, ""rocket"": 1, ""eyes"": 0}",779156520,
