['1', '7', '11'].map(parseInt) doesn’t work as intended because map passes three arguments into parseInt() on each iteration. The second argument index is passed into parseInt as a radix parameter. So, each string in the array is parsed using a different radix. '7' is parsed as radix 1, which is NaN, '11' is parsed as radix 2, which is 3. '1' is parsed as the default radix 10, because its index 0 is falsy.

And so, the following code will work as intended:

['1', '7', '11'].map(numStr => parseInt(numStr));

Unsubscribing should be easy. It’s not.

Hi Is there a way to set up morgan to skip adding new line when using stream option? I am combining morgan's output to winston and both are adding LF line feed which results in double new lines...I can strip out the newline when it comes...

This is how

var split = require('split');
var winston = require('winston');
winston.emitErrs = true;

var logger = new winston.Logger({
    transports: [
        new winston.transports.File({
            level: 'info',
            filename: './logs/all-logs.log',
            handleExceptions: true,
            json: true,
            maxsize: 5242880, //5MB
            maxFiles: 5,
            colorize: false
        }),
        new winston.transports.Console({
            level: 'debug',
            handleExceptions: true,
            json: false,
            colorize: true
        })
    ],
    exitOnError: false
});

module.exports = logger;
module.exports.stream = split().on('data', function (message) {
  logger.info(message);
});

Hmmm, I do recognize a few of the symptoms mentioned here.
