# Headwind Simulations API Client for FlyByWire API

This is a unofficial JavaScript client for the FlyByWire API and changed for Headwind Simulations needs.
The library supports both JavaScript and TypeScript.
If you want to use the FlyByWire API stick to the Official API-Client: https://github.com/flybywiresim/api-client


## Installation

Install the client library using npm:

    $ npm install --save @headwindsimulations/api-client

## Usage

### Initializing the client
```ts
import { NXApi } from '@headwindsimulations/api-client';

NXApi.url = new URL('http://localhost:3000');
```

By default, the URL is set to `https://api.flybywiresim.com`. If this is the desired URL this step can be omitted.

### METAR
```ts
import { Metar } from '@headwindsimulations/api-client';

Metar.get(icao, source)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `icao` is a string of the the airport ICAO code to get the METAR for.
- `source` is the selected datasource for the METAR and is _optional_.
  Valid sources are:
  - vatsim
  - ms
  - ivao
  - pilotedge

### TAF
```ts
import { Taf } from '@headwindsimulations/api-client';

Taf.get(icao, source)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `icao` is a string of the the airport ICAO code to get the TAF for.
- `source` is the selected datasource for the TAF and is _optional_.
  Valid sources are:
  - aviationweather
  - faa

### ATIS
```ts
import { Atis } from '@headwindsimulations/api-client';

Atis.get(icao, source)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `icao` is a string of the the airport ICAO code to get the ATIS for.
- `source` is the selected datasource for the ATIS and is _optional_.
  Valid sources are:
  - faa
  - vatsim
  - ivao
  - pilotedge

### Airport
```ts
import { Airport } from '@headwindsimulations/api-client';

Airport.get(icao)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `icao` is a string of the the airport ICAO code to search for.


### ATC
```ts
import { Atis } from '@headwindsimulations/api-client';

ATC.get(source)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `source` is the selected datasource for the ATC.
  Valid sources are:
  - vatsim
  - ivao


### TELEX connection handling

#### Connect to TELEX system
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.connect(status)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `status` is of type `AircraftStatus` and contains information about the current flight.

The backend might block certain flight numbers from being used for various reasons.

#### Update the TELEX status
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.update(status)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `status` is of type `AircraftStatus` and contains information about the current flight.

The status has to updated every 6 minutes for the connection to stay alive.
It is recommended to update the status every 15 seconds for a usable live map.
The status can only be updated once a connection has been established.

#### Disconnect from TELEX system
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.disconnect()
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

The connection can only be disconnected once it has been established.
This releases the flight number for reuse and removes the flight from the live map.

### TELEX message handling

#### Sending a message
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.sendMessage(recipient, message)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `recipient` is a string containing the flight number of the recipient flight.
- `message` is a string containing the message to send.

Messages will be filtered for profanity in the backend.

#### Receiving messages
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.fetchMessages()
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

Messages can only be received once and will be acknowledged by this transaction.

### TELEX Querying

#### Fetch a single page of active connections
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.fetchConnections(skip, take, bounds)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `skip` is a number and tells the backend to skip the first n connections.
- `take` is a number and tells the backend how many connections to send.
- `bounds` is an optional bounding box. Query only connections within this area.

`take` and `skip` are used to control the pagination. A maximum of 100 entries can be fetched at a time.

#### Fetch all active connections
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.fetchAllConnections(bounds, callback)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `bounds` is an optional bounding box. Query only connections within this area.
- `callback` gets called after every fetched page.

#### Fetch a certain connection
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.fetchConnection(id)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `id` is the unique identifier of the connection.

#### Find all active connections matching a flight number
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.findConnection(flight)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `flight` is the flight number to search for.

#### Count active connections
```ts
import { Telex } from '@headwindsimulations/api-client';

Telex.countConnections()
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

### Github

```ts
import { GitVersions } from '@headwindsimulations/api-client';

GitVersions.getNewestCommit(user, repo, branch)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `user` the owner of the repository.
- `repo` the repository.
- `branch` the requested branch.

#### Get all releases for a repository
```ts
import { GitVersions } from '@headwindsimulations/api-client';

GitVersions.getReleases(user, repo)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `user` the owner of the repository.
- `repo` the repository.

#### Get open pull requests for a repository
```ts
import { GitVersions } from '@headwindsimulations/api-client';

GitVersions.getPulls(user, repo)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `user` the owner of the repository.
- `repo` the repository.

#### Get the artifact URL for a pull request
```ts
import { GitVersions } from '@headwindsimulations/api-client';

GitVersions.getArtifact(user, repo, pull)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
});
```

- `user` the owner of the repository.
- `repo` the repository.
- `pull` the number of the pull request.


### Charts

#### Get the charts for an airport
```ts
import { Charts } from '@headwindsimulations/api-client';

Charts.get(icao, source)
  .then(data => {
    console.log(data);
  }).catch(err => {
    console.error(err);
