Logger-rotate NPM

logger-rotate

Log messages to files that are rotated on a schedule.

The three methods console.log, console.warn, and console.error can be swapped out for either synchronous or asynchronous logger-rotate equivalent methods.

Separate files for the three levels of logging are stored and rotated for new empty files daily.

A history of older log files is available, and a list of the most recent messages is also available.

Installation

$ npm install logger-rotate --save

Optional - Set the path where logs should be stored. Eiher relative or absolute:

$ node ./node_modules/logger-rotate/index.js setLogFolder ./logs

Usage

Synchronous Operation:

var logger = require("logger-rotate");

logger.logSync("Hello World", false);

logger.warnSync("Warning!!!", false);

logger.errorSync("Game Over!", true);

(The second parameter in the synchronous methods is optional and denotes whether to run silently or not i.e. don't show a console message - default is false)

Asynchronous Operation:

logger.log("Hello World", () => {
    console.log(":-)");
  });

logger.warn("Warning!!!", () => {
    console.warn(":-|");
  });

logger.error("Game Over!", () => {
    console.error(":-(");
  });

Extras:

To check on the most recent messages:

logger.showrecent(50);

The parameter is the number of recent messages to show (up to 999)

Tests

npm test
