How to disable console logging entirely (express-openapi)?

[TitaniteSlab]

I see #61 but I still don't understand how.

Specifically, when Content-Type is provided but invalid, I'm getting a stack trace in my server console:

failed to parse content-type foo TypeError: invalid media type
    at Object.parse (/foo/node_modules/content-type/index.js:126:11)
    at getSchemaForMediaType (/foo/node_modules/openapi-request-validator/index.ts:385:37)
    at OpenAPIRequestValidator.validateRequest (/foo/node_modules/openapi-request-validator/index.ts:257:30)
    at requestValidatorMiddleware (/foo/node_modules/express-openapi/index.ts:132:48)
    ... more lines

How do I get rid of this? I want to use a noop logger.

import { initialize } from 'express-openapi';
initialize({
  logger: {
    error: () => {},
    warn: () => {},
    info: () => {},
    debug: () => {}
  },
  ...
});

Seems to work.

it'd be nice to have logger: null support though to just disable it entirely

or logger: false

Could use dummyLogger from ts-log. Already used in openapi-request-validator as a default, and it's installed in openapi-framework.

If null were to be supported at library-level to disable logging entirely it'd probably easiest be done as:

• Change type of logger on OpenAPIFrameworkArgs from ?: Logger to ?: Logger | null
• Change the way this.logger is set on class OpenAPIFramework to:

if (args.logger) {
  this.logger = args.logger;
} else if (args.logger !== null) {
  this.logger = new ConsoleDebugAdapterLogger();
} else {
  this.logger = dummyLogger;
}

Can't really see any meaningful way of checking this in the test suite though beyond adding cases that instantiate OpenAPIFramework with null and undefined values for logger to assert it doesn't throw though since the logger member is private and we wouldn't be able to check what it's an instanceof / if it's exactly the dummyLogger.

@jsdevel Can you let me know if you're happy with this solution as-is or if you'd want any extra changes made? e.g. Adding a public getter for the logger to check its type in tests, etc. I'll be happy to put a PR in for this when I get some time this week.
