Logmatic

An overly complicated yet functional logger.

Installation

For all systems, please use:

npm i logmatic --save-exact

As logmatic is currently in a very unstable state, many items may change in the future.

Usage

To get started, import the project into your file and initialise the logger:

const { Logger } = require('logmatic');
// OR
// import { Logger } from 'logmatic';

const log = new Logger("name");

For the default added levels, use the following:

Function Call	Format	Colour
log.trace()	{time} [trace] {name} {...data}	Cyan
log.debug()	{time} [debug] {name} {...data}	Blue Background
log.info()	{time} [info] {name} {...data}	Blue
log.warn()	{time} [warn] {name} {...data}	Yellow
log.error()	{time} [error] {name} {...data}	Red
log.fatal()	{time} [fatal] {name} {...data}	Red Background

For your custom levels, please see Levels below

Options

The following section is expecting you have imported the class. It will then demonstrate how to set the option.

Console

Enabled

Whether console logging is enabled

Default: true

const log = new Logger("name", { console: { enabled: true }})

---

Enabled

Whether file logging is enabled

Default: false

const log = new Logger("name", { files: { enabled: false }})

---

Path

The log directory

Default null

const log = new Logger("name", { files: { path: null }})

---

Data Type

The data type sent

Default: json

const log = new Logger("name", { web: { type: "json" }})

---

Every number

How many logs to store before POSTing to avoid getting ratelimited

Default: 5

const log = new Logger("name", { web: { every: 5 }})

---

Levels

This logger allows you to add your own levels, following out format. Formatted the following:

const log = new Logger("name", { levels: { name: "level", colour:"red" }})
// **OR**
const log = new Logger("name", { levels: [{ name: "level", colour:"red" }]})

The colour should be derived from the package console-log-colors or from a slimmed list included in the types.

Also, you are able to overwrite existing functions. For example, you could overwrite the info logger level by redefining it.

Functions

The logger allows you to pass custom functions or callbacks to handle the logs on your own.

const function = (level: number, ...data: any[]) => {
    return { level, data }
}

const log = new Logger("name", { funcs: function});
// **OR**
const log = new Logger("name", { funcs: [function]});
