winston

问题 I want to use winston logger in node app for log error to file. But winston not write to file. var logger = new (winston.Logger)({ transports: [ new (winston.transports.Console)(), new (winston.transports.File)({ filename: 'somefile.log' }) ] }); logger.error('test'); file somefile.log is created but empty. 回答1: You need to define a level in the constructor. var tsFormat = () => (new Date()).toLocaleTimeString(); var log = new (winston.Logger)({ transports: [ new (winston.transports.Console)(

问题 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

问题 My logger is set up like: const myFormat = printf(info => { return `${info.timestamp}: ${info.level}: ${info.message}: ${info.err}`; }); const logger = winston.createLogger({ level: "info", format: combine(timestamp(), myFormat), transports: [ new winston.transports.File({ filename: "./logger/error.log", level: "error" }), new winston.transports.File({ filename: "./logger/info.log", level: "info" }) ] }) Then I am logging out some error like this: logger.error(`GET on /history`, { err }); How

问题 I have several modules - let's say server.js, module1.js,...,moduleN.js. I would like define the log file in my server.js: winston.add(winston.transports.File, { filename: 'mylogfile.log' }); and then use it in all my modules. What is the best way to do that? I could exports.winston=winston; in each module and then set it in the server.js, but is there any better solution? Thank you in advance! 回答1: The default logger concept handles this nicely. Winston defines a default logger that any

问题 We'd like to use Winston for our logging in Node.js. But, we can't figure out how to have two log files: one for just errors, and one for everything else. Doing this the naive way doesn't work, however: adding multiple winston.transports.File transports gives an error. Others have run into this problem, with vague hints of a solution, but no real answer. Any ideas? 回答1: I just sent a pull request that allows using multiple File transports in one logger. https://github.com/flatiron/winston

问题 we use morgan in order to log our express transformation: var morgan = require('morgan'); morgan('combined'); // a format string morgan(':remote-addr :method :url :uuid'); // a custom function morgan(function (req, res) { return req.method + ' ' + req.url + ' ' + req.uuid; }) Also, we use winston in order to log our other logging: var winston = require('winston'); var logger = new (winston.Logger)({ transports: [ new (winston.transports.Console)({ level: 'info' }), new (winston.transports

问题 I'm trying to create a channel switch logger which allows me to specify a channel where the messages get posted. So, for example, I create a TextChannel called "Channel Switches". When now a user changes voice channel, it should appear a message in this Channel. (eg. <USER> left channel <CHANNEL> and joined <CHANNEL>. ) MY PROBLEM IS: I get no errors and the Bot is not responding... Here my first try: var Discord = require('discord.js'); var logger = require("winston"); var auth = require(".

问题 I want to flush the winston logger before process.exit . process.on('uncaughtException', function(err){ logger.error('Fatal uncaught exception crashed cluster', err); logger.flush(function(){ // <- process.exit(1); }); }); Is there anything like logger.flush available? I couldn't find anything about it, other than people complaining about winston not being very actively maintained. As an alternative, is there any popular (actively maintained) multi-transport logging framework that provides a

问题 I am working in node js and using Winston library for logging. The following code does not create a log file. var winston = require('winston'); var logger = winston.createLogger({ 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 });

问题 I am applying logger in node js application using Winston but getting winston.Logger is not a constructor. I am following the link below http://thisdavej.com/using-winston-a-versatile-logging-library-for-node-js/ 回答1: Try something like below code, it should work (it might have happened since you have been using an older code for the newer version): const winston = require('winston'); require('winston-daily-rotate-file'); function getLogger(module) { const transport = new winston.transports
