Geolocation APIをPromiseでラップして扱う(TypeScript)

More than 1 year has passed since last update.

Geolocation APIを扱う場合、awaitを使えた方が便利なことが多いので
Promiseでラップするようにしました。

sample.ts
  // API呼び出し
  getCurrentPosition() {
    return new Promise(
      (
        resolve: (value?: Position) => void,
        reject: (reason?: PositionError) => void
      ) => {
        navigator.geolocation.getCurrentPosition(resolve, reject);
      }
    );
  }

  // 使う場合はこんな感じで
  async foo() {
    const s = await this.getCurrent();
    console.log(s.coords);
    // 結果(例)
    // Coordinates {latitude: 35.681167, longitude: 139.767052,
    // altitude: null, accuracy: 40, altitudeAccuracy: null, …}
  }

何かの役に立てば幸いです。
