Inside the backquote, if I start a new line, the printed string will start a new line as well.

e.g.

  winston.format.printf(
    (info) => `${info.timestamp}  ${os.hostname()} ${process.pid} ${info.level}: ${info.message}`,
  ),

will print

2021-Nov-30 01:27:39:2739  MacBook-Pro.local 56939 info: initializeExpress() COMPLETED

But

  winston.format.printf(
    (info) => `${info.timestamp}  ${os.hostname()} 
               ${process.pid} ${info.level}: ${info.message}`,
  ),

will print:

2021-Nov-30 01:27:39:2739  MacBook-Pro.local
    56939 info: initializeExpress() COMPLETED

I had to start a new line in the code because of code specification. But I need to avoid starting a new line in the log message.

How?

End the template literal at the end of the first line, and concatenate with the next with +.

  winston.format.printf(
    (info) => `${info.timestamp}  ${os.hostname()} ` +
              `${process.pid} ${info.level}: ${info.message}`,
  ),
