A modular, color-coded, TypeScript-based semantic logger that can be used in NodeJS, the browser and in many other scenarios.

## Example

```ts

// Import the logger:

import Logger, { BrowserLogger } from '@fliegwerk/logsemts';

// Create a new logger

const logger = new Logger({

	loggers: [BrowserLogger()] // that exclusively outputs to the browser dev tools

});

// get a new subsystem logger for the API Client

const apiClientLogger = logger.getComponentLogger('API Client');

// log a success message

apiClientLogger.success('Data fetched successfully');

```

## Installation

```shell script

$ npm install @fliegwerk/logsemts

```

or

```shell script

$ yarn add @fliegwerk/logsemts

```

## Concept

![Concept Overview Diagram](assets/drawio/concept-overview.png)

There are three primary components in logsemts:

- _Component Loggers_: Logger objects for specific subsystems (for example, an API connector and a login form).

  These objects contain functions like `.log()`, `.debug()`, `.warn()`, etc. to log messages regarding this subsystem.

- _Log Functions_: Functions that log a message to a specific target. Targets could be the Browser's Developer tools, a

  Database and an API.

- _Core_: The library's core consists of the `Logger` class. Usually, only one instance of that class gets used in an

  application. It manages the different components (_Component Loggers_ get created using the

  `logger.getComponentLogger(name)` function) and _Log Functions_. It also forwards the messages from the _Component

  Loggers_ to the registered _Log Functions_.
