Tgsnake Log

This framework is used to better display logs on your console or terminal.

Available log levels

This framework using env in node and localStorage in browser for betters performance :

• LOGLEVEL : To save the log level. So only declaring in one instance, all instance can read that log level.

• LOGFILTERS : To save any instance that can display context on console or terminal (according to the name that was given at the time of initialization). default is all,unamed.

• LOGWARNINGLEVEL : To save the warning level.

• debug or verbose : To showing all level in terminal.

• info : Shows only context with level info on console or terminal.

• error : Shows only context with level error on console or terminal.

• warn : Shows only context with level warn (warning) on console or terminal.

• none : Will not display anything on console or terminal

How to use

const { Logger } = require('@tgsnake/log');
const log = new Logger({
  name: 'some-string-without-space-here',
  level: ['debug'], // default level for this log
});

log.log('Hello World'); // (name) info - Hello World DD/MM/YY hh:mm:ss.ms

Class Method

• log : Print log without template.
• info : Print log as info level.
• error : Print log as error level.

• combine : Print log as multiple level.
• debug : Print log as debug level.
• setLogLevel : Setting the log level.

• setFilters : Setting any instance that can display context in the console or terminal.

Capturing log

The log capture feature is only available on node js and deno platforms, not available for browsers!

To capture logs we use env as the trigger. When in the env have CAPTURELOG The capture function will automatically work and stop when the program is finished (beforeExit event on node and beforeunload event on deno) or when it is forced to stop due to an error (unhandledRejection event on node and unhandledrejection on deno).
The log will be captured in the form of a log file with filename format: {name}-{Date.now()}.log and will be saved in the current work dir (cwd).
Value of env CAPTURELOG is name of logger or can be 'all' for each instance the logger runs the capture function.

Example :

CAPTURELOG=tgsnake

With the example above, only the instance named tgsnake performs the capture function.

CAPTURELOG=all

With the example above, all of the instance logger will be performs the capture function.

You don’t need to create an .env file, you can do it like this :

CAPTURELOG="all" node index.js

Options

Color

On deno supports chalk v5 customization while on node supports chalk v4 customization. For RGB, HSL (only for node), HSV (only for node), HWB (only for node), you can use the format: format(a,b,c) example rgb(0,0,0) or hsl(0,0,0). And you can directly provide the hex code (eg: #fff). In nodes, you can also use keywords from CSS like orange.

Example

const { Logger } = require("@tgsnake/log")
const log = new Logger({
  name : "some-string-without-space-here",
  level : ["debug"] // default level for this log,
  customColor : {
    debug: 'blue',
    info: 'rgb(0,255,0)',
    error: '#ff0505',
    warning: 'hsv(44,98,100)',
    name: 'azure',
    date: 'grey',
  }
})
