如何为winston.createLogger（）提供不同的标签作为参数

Question

var logger = winston.createLogger({
    format: combine(
        label({ label: 'abc' }),
        prettyPrint()
      ),
    transports: [ new winston.transports.Console() ]
  });

exports.logger = logger;

如果不是标签：“ abc”，我想传递“ pqr”，“ xyz”，怎么办？

您可以通过将动态值分配给如下所示的变量来实现：

    var dynamicValue = "abc"; // value can change
    var logger = winston.createLogger({
        format: combine(
            label({ label: dynamicValue }),
            prettyPrint()
          ),
        transports: [ new winston.transports.Console() ]
      });

    exports.logger = logger;
