    extended-console

    2.2.0 • Public • Published

    extended-console

    Extends default console logging with various utilities.

    Features

    • Prepend timestamp to output using Moment.js' format
    • Prepend log level (ie, log, inf, war, err)
    • Attach events to be called when something is logged using any of the 4 log functions

    Usage

    First install it using npm

    npm install extended-console
    

    Then simply require it and log away!

    require("extended-console");
    
    console.log("Log away!");
    

    Options

    Options are located within the console.extended object.

    • showTimestamp ( boolean ) Whether to prepend a timestamp to output
    • timestampFormat ( string ) Format for timestamp. Uses Moment.js' format
    • showLogLevel ( boolean ) Whether to prepend the log level to output

    For example

    require("extended-console");
    
    console.extended.timestampFormat = "YYYY-MM-DD HH:mm";
    console.log("Custom timestamp format!");
    

    Events

    This module extends the console to act as a standard event emitter. You can use standard events.EventEmitter methods such as .on and .addListener on the console.extended object. The event names are as follow: log, inf, war, err. Be careful not to call any of the logging functions inside of an event callback for that logging function itself, for it will result in a stack overflow.

    Example

    console.extended.on("err", function() {
    	process.stdout.write("Error event listener called\n");
    });
    console.error("Error event listener test");
    

    Changelog

    2.2.0

    • Events now called with potential prepended string in arguments
    • No longer prepend empty string (used to produce superfluous space character)

    2.1.1

    • Fixed bug that caused events not to be emitted

    2.1.0

    • Added event support
    • Changed log level logging to use following short names: log, inf, war, err. This is for consistency with events

    (previously 0.2)

    Breaking changes

    • Added option to prepend log level (on by default)
    • Switched to Moment.js for date formatting
