winston-rotating-file

Description

Transport for winston based on rotating-file-stream.

Usage

const { WinstonRotatingFile } = require("winston-rotating-file");
const winston = require("winston");

const logger = winston.createLogger({
  format: winston.format.combine(
    winston.format.timestamp({ format: "YYYY-MM-DD HH:mm:ss" }),
    winston.format.printf(info => `${info.timestamp} ${info.message}\n`)
  ),
  transports: [
    new WinstonRotatingFile({
      filename: "file.log",
      rfsOptions: {
        size: "10M", // rotate every 10 MegaBytes written
        interval: "1d", // rotate daily
        compress: "gzip" // compress rotated files
      }
    })
  ]
});

or (if access to rotating-file-stream events is required)

const { WinstonRotatingFile } = require("winston-rotating-file");
const winston = require("winston");

const transport = new WinstonRotatingFile({
  filename: "file.log",
  rfsOptions: {
    size: "10M", // rotate every 10 MegaBytes written
    interval: "1d", // rotate daily
    compress: "gzip" // compress rotated files
  }
});

transport.stream.on("rotated", filename => {});

const logger = winston.createLogger({
  format: winston.format.combine(
    winston.format.timestamp({ format: "YYYY-MM-DD HH:mm:ss" }),
    winston.format.printf(info => `${info.timestamp} ${info.message}\n`)
