I have a method getRoute that takes a video. The video is either of LiveVideo type or RecordedVideo type. My problem is that getLiveID field is only in LiveVideo so I am getting the editor issue property getLiveID does not exist on type RecordedVideo. What is the way around this? I want to use 1 method to handle both and handle the conditional logic within.
getRoute(video: LiveVideo | RecordedVideo) {
if (video.getLiveID) {
///
} else {
///
}
}
You can use instanceof:
getRoute(video: LiveVideo | RecordedVideo) {
if (video instanceof LiveVideo) {
// "video" is of type LiveVideo here...
} else {
// ...
}
}
You can check which type you have using in. For example:
getRoute(video: LiveVideo | RecordedVideo) {
if ("getLiveId" in video) {
// treat as LiveVideo
} else {
// as RecordedVideo
}
}
type LiveVideo = {
getLiveID: Function,
id: string
}
type RecordedVideo = {
id: string
}
function getRoute(video: LiveVideo | RecordedVideo) {
if ((video as LiveVideo)?.getLiveID) {
///
} else {
///
}
}
