# Route-emitter (@peter.naydenov/route-emitter)

Tool for building a **micro-frontend(MFE)**. Library `route-emitter` is based on [**react-router**](https://reactrouter.com/en/main) but is not a **'react' platform** dependent. Route change will trigger an event and will execute a callback function if it is defined.

```js 
 let router = routeEmitter ([
                                  { path: '/about/:name', event: 'info' }
                                , { path: 'contact/:name', event: 'showContactInformation' }
                        ])
router.on ( 'info', props => { // Callback definition. Executes on path: '/about/:name'
                        console.log ( `Info about ${props.name}`)
                })
router.on ( 'showContactInformation' , props => { // Callback definition. executes on path: 'contact/:name'
                        console.log ( `Here is the contact information of ${props.name}` )
                })
router.navigate ( '/about/Peter' )
// console --> Info about Peter
router.navigate ( '/contact/Ivan' )
// console --> Here is the contact information of Ivan
```
