winston

I have defined custom levels for my application .They are as follows. protected levels: Level = { "error": 0, "warn": 1, "info": 2, "debug": 3, "trace": 4 }; I am using daily file rotate transport to get daily log in separate files. const options: Object = { name: this.level, filename: logFilePath, dirname: WinstonLogAgent.DIR_LOG, datePattern: "yyyyMMdd.", prepend: true, level: this.level, levels: this.levels, maxsize: this.maxFileSize, maxFiles: this.maxFileCount, handleExceptions: true, humanReadableUnhandledException: true }; this.transportInstance.push(new (winston.transports

Basically i am trying to implement logger for the nodejs , using morgan and winston. When i am trying to use morgan , throwing an error of stream.write is not a function. Since i want get the file name , i am passing the module, from module object there is a property called filename. Below is my code. // Winston.js const appRoot = require('app-root-path'); const { createLogger, format, transports } = require('winston'); const { combine, timestamp, label, printf } = format; const path = require('path'); // Custom Format const customFormat = printf(info => { return `${new Date(info.timestamp)} |

I have an electron application which is using node.js. I would like to use Winston for logging in the application. I've added winston to my package.json file, but when I run the build command for webpack I'm getting some warnings from the colors.js dependency in winston. '...the request of a dependency is an expression...' It then references winston and colors.js. Ignoring the warnings doesn't work, as the electron application gets an exception trying to load some files from winston. I did some digging on SO and the github site and they say that colors.js has some dynamic require statements

I've an Express app. I'd like to trace all the loggings that were made by a single request. Apache has a module called mod_unique_id which injects in the request headers a special one containing a unique hash. I'd like to use such hash when logging (anything). For example if an user is assigned by apache the unique_id valued "abcdefg" and somewhere in my code (controller, model, or anything) i generate a debug log i'd like to have "abcdefg" attached to every log entry. The only idea that pops in my mind is to create a logger instance using app.use() and pass that logger instance to ALL the

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! Nick The default logger concept handles this nicely. Winston defines a default logger that any straight require (and subsequent require) to winston will retrieve. Thus you simply configure this default

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? pesho I just sent a pull request that allows using multiple File transports in one logger. https://github.com/flatiron/winston/pull/149 It is already merged into flatiron/winston.
