How to implement java-like MDC for logging contextual information using winston logger.

I am using winston - 3.0.0-rc5 with operating system as Windows.

Using winston logger, I have formatted log statement to have timestamp, level and message.

    module.exports = {

	namespace: "",
	nodeID: null,
	logger: bindings => winston.createLogger({
		level: "debug",
		format: winston.format.combine(
			winston.format.timestamp(),
			winston.format.printf(log => {
				return `${log.timestamp} ${log.level} ------ ${log.message}`;
			})
		),
		transports: [
			new (winston.transports.Console) ({
					timestamp: true,
					colorize: true,
					prettyPrint: true,
			}) /*,
			new fluentTransport('xxx.xxxxxx', {
				host: 'xx.xx.xx.xxx',
				port: 'xxxx',
				timeout: 3.0,
				reconnectInterval: 60000
			})*/
		]
	}),

On the same line, I need to know the way to implement java-like Mapped Diagnostic Context (MDC) for logging contextual information in a moleculer framework node js microservice using winston logger. Eg.

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- Log message format -->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} [%mdc] - %msg%n
            </pattern>
        </encoder>
    </appender>

Any help on this?

This is a much-needed feature.
Meanwhile, we followed a similar approach as @breznik suggested. We pass requestMeta object from our controller to service and service to as an argument of every log statement. But this takes your ability to pass an object as a second argument.

@indexzero creating child loggers is not solving the issue of sharing a context (which probably varies per request, not per logger). Do you suggest a child logger be created with each change of context ?
