Youtube in React: handling VIDEO_DETAILS_SUCCESS action
function reduceVideoDetails(responses, prevState) {
const videoResponses = responses.filter(response => response.result.kind === VIDEO_LIST_RESPONSE);
const parsedVideos = videoResponses.reduce((videoMap, response) => {
// we're explicitly asking for a video with a particular id
// so the response set must either contain 0 items (if a video with the id does not exist)
// or at most one item (i.e. the channel we've been asking for)
const video = response.result.items ? response.result.items[0] : null;
if (!video) {
return videoMap;
videoMap[] = video;
return videoMap;
}, {});
return {
byId: {...prevState.byId, ...parsedVideos},
