log-talk

Simple logger designed for browser and terminal.

• Line number where a bug occured (only for browser console now)
• Timestamp when a bug occured
• Highlight
• Observe log message
• Customizable

Usage

Use npm to install.

npm install --save log-talk

const LogTalk = require('log-talk');
const logger = new LogTalk();

// Default methods
logger.debug('This is debug');
logger.info('This is info', { message: 'Hello' });
logger.success('This is success');
logger.warn('This is warn');
logger.error('This is error', new Error('There is something wrong'));

// Define your own method
logger.setMethod({ name: 'foo', color: 'yellow', timeFormat: '[[]YYYY-MM-DD HH:mm:ss]' });
logger.foo('Foo');

// Override default methods
logger.setMethod({ name: 'info', color: 'red' });
logger.info('Now the label is red');

You can see this demo here on your browser.

Log level

You can hide low level log such as debug.

const LogTalk = require('log-talk');
const minLevel = 3;
const logger = new LogTalk(minLevel);

Label

Set label option to customize label.
If you don't set label, name option is used as label.

const LogTalk = require('log-talk');
const logger = new LogTalk();
logger.setMethod({ name: 'foo', label: 'Foo' });

Time format

Set timeFormat option to customize time format.

const LogTalk = require('log-talk');
const logger = new LogTalk();
logger.setMethod({ name: 'foo', timeFormat: 'YYYY-MM-DD' });

It depends on Day.js to generate time string.
Formatting rules are here.

Highlight

Set color option to highlight.
NOTE: IE ignores color.

const LogTalk = require('log-talk');
const logger = new LogTalk();
logger.setMethod({ name: 'foo', color: 'yellow' });

These are defined colors.

• default
• blue
• green
• yellow
• red

It's not flexible and few though.
I will improve it soon.
