Shufflizer has no Progressive Web App<\/em><\/a> service workers.\u00a0 There is no off-line scenario.\u00a0 Bad Internet connection?\u00a0 It’s best if you come back later.<\/p>\n Lazy loading <\/em>is the idea of incrementally obtaining only the data necessary to render the viewport.<\/p>\n The user is going to reorder the entire playlist.\u00a0 So I need the entire playlist.\u00a0 I don’t lazy load it.\u00a0 This is what Spotify’s native Windows app does when you click on a playlist.\u00a0 I can tell by the way it performs.\u00a0 It loads the whole thing.<\/p>\n I am not downloading songs.\u00a0 The playlist is just the track listing, not the audio itself.\u00a0 Even for a few thousand songs this is not a challenging amount of data for today’s hardware – even a phone.<\/p>\n I do get all of the album art.\u00a0 I did try lazy loading these images but I did not like the results.\u00a0 It made the user experience more sluggish and strange.\u00a0 I prefer the user wait a couple more seconds up front to get a smooth, normal\u00a0 scrolling experience.<\/p>\n Shufflizer is pure Angular\/TypeScript.\u00a0 MEAN stack?\u00a0 Nope.\u00a0 It’s just the A.<\/p>\n Having no server-side code makes it easy to comply with this rule in the Spotify Developer Terms of Service:<\/p>\nNo lazy loading<\/h6>\n
No server-side code<\/h6>\n
