## Installation

```

npm install --save glob-bus

```

## Example

In this example, all three listeners will be invoked.

```ts

import { globBus } from 'glob-bus';

type Event =

  | { type: 'basket.product.add'; id: number }

  | { type: 'basket.product.remove'; id: number };

const { on, send } = globBus();

on('*', (event: Event) => console.log(1, event));

on('basket.*', (event: Event) => console.log(2, event));

on('basket.product.*', (event: Event) => console.log(3, event));

send({ type: 'basket.product.add', id: 123 });

```

The `on` function returns a function to unregister the given listener:

```ts

import { globBus } from 'glob-bus';

const { on, send } = globBus();

const off = on('basket.product.*', fn);

off();

```
