Custom log formatter

[Maverick1983]

It's possible to remove 'message' field with custom log formatter?

Hi, yes, you can do this with the following custom log formatter implementation, or an equivalent:

import { Logger, LogFormatter } from "@aws-lambda-powertools/logger";
import { LogAttributes } from "@aws-lambda-powertools/logger/lib/types/Log.js";
import { UnformattedAttributes } from "@aws-lambda-powertools/logger/lib/types/Logger.js";

class MyLogFormatter extends LogFormatter {
  public formatAttributes(attributes: UnformattedAttributes): LogAttributes {
    const { message, ...rest } = attributes;

    return { ...rest };
  }
}

You would then use the custom log formatter like this:

const logger = new Logger({
  logFormatter: new MyLogFormatter(),
});

logger.info("test");
