winston

I am trying to create a simple logger class with Winston . I created two loggers named Logger and Error which extends from Logger . The Logger class by default creates all the logs in al-logs.log and Error class when extending from Logger adds an additional transport to create all error logs inside error-logs.log . But no logs are created inside error-logs.log . What am I missing? Here is what I did: First, I created the Logger class: class Logger { constructor(serviceName, label = "") { this.logger = winston.createLogger({ level: "debug", format: winston.format.combine( winston.format.label({

I'm making a Node.js app and I am using Winston for most of my logging purposes. But I find all records in log file in one line, I want to change line for every log record, any way can do this? My code; var winston = require("winston"); var logger = new(winston.Logger)({ transports: [ new(winston.transports.Console)(), new(winston.transports.File)({filename: './log/logFile.log', handleExceptions: true, json:true}) ] }) Just like that: {"level":"info","message":"test","timestamp":"2012-12-05T07:12:23.774Z"} {"level":"info","message":"test","timestamp":"2012-12-05T07:15:16.780Z"} It is not

I am using winston for logging in a node.js application. I see there are options to query it. The example shows how to use options from and to. My question is What are the other options ? How do I specify what file should be queried ? I ran into this same problem. At least some of the options can be found in Winston's transport.js in the function Transport.prototype.normalizeQuery. Here's a quick summary: options.rows, options.limit = how many results to return. default is 10; options.start = starting row offset. default is 0 options.from = date string or date object for starting limit.

I'm trying to set up an access log and an error log for my express server using Winston, but I seem to be doing something wrong. Here is my attempt at a config file: const winston = require('winston'), fs = require('fs'); const tsFormat = () => (new Date()).toLocaleTimeString(); winston.loggers.add('errorLog', { file: { filename: '<path>/errors.log', //<path> is replaced by the timestamp: tsFormat, //absolute path of the log level: 'info' } }); winston.loggers.add('accessLog', { file: { filename: '<path>/access.log', //same as before timestamp: tsFormat, level: 'info' } }); And this is how I'm

Reading and fiddling with Winston, I'm puzzled as to why the logging levels are ordered as they are and why the transports behave in the way they do (well, at least the Console one). I'd appreciate if someone could, perhaps even thoroughly, with real use case examples, explain why logging with Winston works this way? For example, I setup my logger like this : var logger = new (winston.Logger)({ levels: winston.config.syslog.levels, colors: winston.config.syslog.colors, level: "debug", // I'm not sure what this option even does here??? transports: [ new (winston.transports.Console)({ colorize:
