GraphQL query for a specific block (within transition frontier)

[bkase]

We currently have a bestChain query that returns blocks on the best chain within the transition frontier but we don’t have a way to query for individual blocks via hash or height from this interface.

This is very very simple to add from an implementation perspective and is useful.

implementation cost is 5min + overhead of landing a PR

Near zero risk of introducing any regressions

Please don't forget to add the following input:
before: (block number)
after: (block number)
relatedTo: (publicKey)
first: first n elements
last: last n elements

and following output
pageInfo {
firstCursor
hasNextPage,
hasPreviousPage,
lastCursor
}

totalCount

these fields would help front-end work easily.

@crackerli this endpoint is always limited to returning a list of at most size 290 (pending small changes to consensus constants). As such I think the paging system isn’t necessary. Before/after doesn’t add anything on top of height.

relatedTo, first n, last n in bestChain. Should be easy enough to add though

So, if the user has 291 transactions, he may can not see the earliest transaction?

@crackerli it's 290 blocks. If the user's transactions happened outside of those 290 blocks you would have to get from somewhere else e.g. archive node.

Thank you much, I understood

@psteckler I perceive that this issue should be closed. Is that right?

[psteckler]

Yes, closing.
