transactions ordering ASC or new before param

[roccomuso]

Аbstract
Ability to paginate using after param having txs ordered ASC and not DESC.
Or in alternative a before param with txs ordered DESC.

Motivation and Purposes
I'd like to use the after param as a cursor to get recent txs. But in order to do that I should have txs returned ASC by timestamp and not DESC by timestamp. Or in alternative have a param like before.

Specification
Return txs before a given txid and not only after or in alternative give a way to list txs ASC by timestamp.

Backwards Compatibility
100% compatible

Examples and Implementation

Ark, Lisk and other coins already implement this.

Hi @roccomuso, thanks for reaching out.
In order to get the most recent transactions, you can use an use the existing API. Suppose tx_id is the most recent transaction you've loaded "the last time". Loading transactions between tx_id and now can be achieved by repeatedly calling /transactions/address/{address}/limit/{limit} and changing after param to the last transaction's id until you get tx_id in the response, and then sorting the resulting list on the client side. This method might be a little less convenient than explicitly requesting transaction ordering, but it can still be used as a workaround.

We'll consider adding sort order parameter (or extending API in some other way) in some of the future releases.

It's a workaround that will require multiple calls (not so convenient for wallets having a lot of txs), I think would be easier to improve api server-side introducing a order param
