Transform your console.log
into a customized logs.
This does not override the default console.log
, it just add a new way to debug with CSS styles.
npm install stylish-log
Then you call it with import
or require
:
import log from 'stylish-log'
//OR
const log = require('stylish-log');
There are 4 stylish-log methods that you can use:
- log.show
- log.info
- log.warn
- log.danger
The default styles for these methods are:
const styles = {
default: 'color: gray; font-weight: bold;',
info: 'color: blue; font-weight: bold;',
warn: 'color: #ffc107;',
danger: 'color: lightcoral; font-weight: bold;'
}
See how this example are shown in console
log.show('default')();
log.info('info')();
log.warn('warn')();
log.danger('danger')();
You can pass how many values you want to stylish-log methods, if you have more than just one, the first string message becomes a "label message" for your log. Take a look:
const arrObj = [
{
"obj1": "lorem value",
"obj2": "lorem value"
},
{
"obj1_2": "lorem value",
"obj2_2": "lorem value"
}
]
const arr = ['arr', 'arr2', 'arr3'];
const fn = function(){
console.log('A function');
}
//call stylish-log for each value passing a custom message label
log.show('label message:', arrObj)();
log.info('label message:', arr)();
log.warn('label message:', arr, arrObj)();
log.danger('label message:', fn)();
See how this example are shown in console
You have total freedom to override the default styles for each method
log.styles.default = 'font-size: 14px; color: #795548; text-transform: uppercase;';
log.styles.info = 'font-size: 14px; background: #4fc3f7; color: white;';
log.styles.warn = 'font-size: 14px; color: black; background: linear-gradient(to right, #ffa726, #ffe0b2)';
log.styles.danger = 'font-size: 14px; color: white; text-shadow: 0 1px 0 black, 0 0 8px red;';
As you can see even gradients are supported.
Another example with images:
log.styles.default = 'background: url(https://i.imgflip.com/1plo8j.jpg) left bottom no-repeat; background-size: contain; display: block; padding: 150px 80px';
log.show('')();
Assuming that the padding
is respectively height
and width
you can set an image to console.
In this case the default style was overrided and then log.show('')()
was called, passing an empty string to initiate the image log.
What about emojis? Yes you can!
log.styles.default = 'font-size: 50px;';
log.show('🐴', 'go horse')();
You should have noticed about the double ()() call from the methods in the examples. There was an initial version (not published) that you could just call the methods with single (), the reason of the double ()() are the stack trace in the console. You can see the difference between below:
log.show('testing single () call');
log.show('testing double ()() call')();
In fact, this module is just a stylish console.log
which provides a simple way to customize your logs with CSS styles.
You can take the same effect using the example console.log(%c My log message, 'color: gray; font-weight: bold;')
this will generate the same result as log.show('My log message')()
.
If you prefer an elegant and useful way to style your console, feel free to use and enjoy it.
