## RdviewService

```
constructor({ apiUrl = 'https://i.centr.by/rdview/api',
    authorization = ''
  }: RdviewServiceConfig = { })
```

authorization: 'Bearer YOUR_OAUTH_TOKEN'


Before usage service must be inited by coordinates or road id and km:

```
initByRoad(idRd: number, km: number): Promise<CurrentPosition>
initByCoordinates(lat: number, lon: number): Promise<CurrentPosition>

// coordinates format - decimal degrees
rdviewService.initByCoordinates(52.34, 28.9)

// 30000001 = M1 E30
rdviewService.initByRoad(30000001, 150)
```

Resolved promise after initialization contains CurrentPosition on road.

When inited, current position can be changed by methods

```
getNextView(): Promise<CurrentPosition>
getPreviousView(): Promise<CurrentPosition>
setPassage(passageId, rdKm?): Promise<CurrentPosition>
```

Current position information can be fetched by methods:

```
getCurrentView(): View
getCurrentPassage(): Passage
getAllPassages(): Passage[]
getSegment(): Segment
getCurrentPosition(): CurrentPosition
```

## RoadService

```
constructor({ apiUrl = 'https://i.centr.by/rdview/api',
    authorization = ''
  }: RoadServiceConfig = { }) {
```

authorization: 'Bearer YOUR_OAUTH_TOKEN'

Search roads by name:

```
getRoads(search: string): Promise<Road[]>
```
