GraphQL and Relay has a robust pagination algorithm which enables easy pagination for the end user, allowing pagination even in unbounded and order-independent results.
However, I have a use case that I'm not really sure how to go about doing in GraphQL and relay, and it's quite easy that I'm sure I just missed something.
How do I, for example, get the 5th item (and only the 5th item), if my list is ordered (by, say, an orderBy argument)?
This not very well documented, but here's how to do it.
query {
allPeople(first: 5, last: 1) {
edges {
node {
name
}
}
}
}
First you select first: 5 to get the first 5 people in the list. Then, do last:1 which gets the last person from that subset. In other words - get the fifth person.
If you do (first: 5, last: 2) you would get the 4th and the 5th person in the list.
Demo
(if it returns an error - manually re-type the word query in the query and it will work). Then, try again without first and last to see the whole list and you'll see that Leia is 5th.
