dsi-aws-boilerplate

Deprecated

Please don't use this if you are starting a new project please look at: aws-lambda-logger

KMS Is deprecated we use SSM now

The logger is in aws-lambda-logger

Usage

Create an instance of the logger at the top of your handler method and pass it through to anything that needs logging so that all logs remain connected by their awsRequestId.

Note: When logging typescript errors, it's recommended to wrap the error in the serializeError method so that everything is logged correctly. Errors thrown may be more complex than a simple typescript Error object and have complex properties that the logger won't pick up by default.

...
import { createLogger, Logger, serializeError } from 'dsi-aws-boilerplate';
...

export const handlerMethod = async (event: any, context: any): Promise<any> => {
    let logger: Logger;

    try {
        logger = createLogger(!!(event?.debug || process.env.DEBUG), context.awsRequestId);
        ...
        logger.debug('event', { event: event });
        ...
    } catch (error) {
        logger?.error('handler_error', { error: serializeError(error) });
        ...
    }
};
