winston

问题 I have read the docs for logging in node.js using the winston package. My question: Do I need to add my logging module to every single page that requires logging.. or does winston somehow intercept console.log and console.error . thanks for your time. 回答1: Normally, you'd need to require your logger in the modules that use it. However, you can follow the suggestion made by @spmason in the gist logging.js or what @fega suggests in his comment to redefine the properties of the console Object:

问题 I've got a node application in which I use Winstonjs as a logger. In my logger I've got a specific part for logging exceptions like this: const myFormat = winston.format.printf(info => { return `${info.timestamp} ${info.level}: ${info.message}`; }); const logger = winston.createLogger({ level: "debug", format: winston.format.combine(winston.format.timestamp(), myFormat), // winston.format.json(), transports: [ new winston.transports.File({filename: "logs/error.log", level: 'error'}), new

问题 I am using Winston logging with my Node.js app and have defined a file transport. Throughout my code, I log using either logger.error , logger.warn , or logger.info . My question is, how do I specify the log level? Is there a config file and value that I can set so that only the appropriate log messages are logged? For example, I'd like the log level to be "info" in my development environment but "error" in production. 回答1: Looks like there is a level option in the options passed covered here

问题 Can Winston logging be selectively disabled when executing unit tests of a node module? Ideally, I'd like to have logging for informational and debug purposes when the application is running, but be suppressed as to not clutter the presentation unit test results when I run my tests. My use of winston is internal to my module, something like this: // MyModule.js var logger = require('winston'); module.exports = function() { // does some stuff // and logs some stuff like so: logger.log('an

问题 Hey i am using this winston logger, kindly explain use of level inside the transports, what will happen if i use logger with info while logging, do i have to use debug while i log my data. var logger = new (winston.Logger)({ transports: [ new (winston.transports.Console)({ level: 'debug', json: true }), new (winston.transports.File)({ name: 'order_check', filename: './logs/order_check.log', level: 'debug' }) ] }); logger.log("info","request body"); 回答1: The level inside your transport

问题 I am trying to mock a winston.Logger instance that is encapsulated within a service class created with NestJS. I have included my code below. I cannot get the mocked logger instance to be triggered from within the service class. Can anyone explain where I am going wrong? import * as winston from 'winston'; import { loggerOptions } from '../logger/logger.config'; import { LoggingService } from '../logger/logger.service'; const logger: winston.Logger = winston.createLogger(loggerOptions); //
