I was creating a new component on my app on which I need to display tags while the user is typing them (the best example here is when we’re creating a post on Stackoverflow and we’re adding these tags).
This collection has tagTitles, userId (this is not sending to user) and counts. Quite simple.
Now I saw 2 different ways to archive this:
A. Subscribe to everything and find the tags that we want
Meteor.subscribe('tags'); // executes just once at beginning
and
Tags.find({tagName: 'tag-name'}); // executes every time we want to find tags
B. Subscribe just to what we’re looking for
// executes every time we want to find tags
Meteor.subscribe('food', () => [{
limit: 21
}, 'tag-name'
], function (err) {
if (!err) {
Tags.find();
}
});
The problem that I found with option B is that the callback doesn’t work properly. It’s too fast and you have to move the find() inside an autorun()
This is regarding to one post I saw recommending the using of find()[0] instead find() because the result is “much” faster.
What do you think guys, which approach is more efficient and faster?
