# Development

To make development a more pleasurable experience, `structlog` comes with the `structlog.dev` module.

The highlight is `structlog.dev.ConsoleRenderer` that offers nicely aligned and colorful console output while in development:

To use it, just add it as a renderer to your processor chain. It will recognize logger names, log levels, time stamps, stack infos, and tracebacks as produced by `structlog`’s processors and render them in special ways.

Suggested configuration for standard library logging:

    import structlog

    structlog.configure(
        processors=[
            structlog.stdlib.add_logger_name,
            structlog.stdlib.add_log_level,
            structlog.stdlib.PositionalArgumentsFormatter(),
            structlog.processors.TimeStamper(fmt="%Y-%m-%d %H:%M.%S"),
            structlog.processors.StackInfoRenderer(),
            structlog.processors.format_exc_info,
            structlog.dev.ConsoleRenderer()  # <===
        ],
        context_class=dict,
        logger_factory=structlog.stdlib.LoggerFactory(),
        wrapper_class=structlog.stdlib.BoundLogger,
        cache_logger_on_first_use=True,
    )
