# evtm

*A lightweight zero-dependency event manager with flexible event type matching*

## Usage

Initialization:

```js

import {EventManager} from 'evtm';

let eventManager = new EventManager();

```

Adding a handler of a specific event type:

```js

eventManager.addListener('task started', event => {

    console.log(event);

});

```

Of all events matching the pattern:

```js

eventManager.addListener(/^task\s/, event => {

    console.log(event);

});

```

With captured parameters:

```js

eventManager.addListener(/^(\S+)\s(?.*)$/, event => {

    console.log(event.params[0], event.params.status);

});

```

Adding a handler of all events dispatched to the `eventManager` instance:

```js

let listener = eventManager.addListener('*', event => {

    console.log(event);

});

```

Dispatching an event of a specific type and properties:

```js

eventManager.dispatch('task started', {x: 42});

```

Removing a previously declared listener:

```js

listener.remove();

```
