js-stellar-sdk: Smart Contracts: Support new txn types, events, and contract calls

[paulbellamy]

Once either https://github.com/stellar/stellar-protocol/blob/master/core/cap-0050.md or https://github.com/stellar/stellar-protocol/blob/master/core/cap-0052.md lands. Let's go with @jonjove's option below for now and change it again when the caps finalize.

TODO

• Support new txn envelope or operation (see caps)
• Support calling contract RPC endpoints
• Support parsing new SCVal types and events.
• Update the docs (Filed an issue on js-soroban-sdk repo for this)

[jonjove]

A prototype operation can be found here https://github.com/stellar/rs-stellar-xdr/blob/main/xdr/next/Stellar-transaction.x#L69 with the additional restriction that if you use this it must be the only operation in the transaction (not the only kind of operation, the only operation as in there must be exactly 1). This is almost sure to change in the future, but it should be an acceptable starting point.

[paulbellamy]

Goal for this stage is something we could use for the end-to-end example dapp https://github.com/stellar/jump-cannon-deliverables/issues/18 for now.

XDR Updates are in stellar/js-stellar-base#538

[paulbellamy]

These are done in the soroban branches of js-stellar-base and js-stellar-sdk. Maybe that is good enough for now? Will the npm release process even let us do better than that? < cc @Shaptic

@paulbellamy should the priority and iteration for this issue be updated? I see we have decided as noted above this will go with @jonjove 's option and we will fix it later when the CAPs are finalized.

@paulbellamy just saw this - you could set a tag before publishing (off the top of my head, the syntax is something like yarn publish --tag=<x>), e.g. we used a beta tag (see the Versions tab under stellar-sdk) when we were working on the AMM release (iirc). You could have a soroban tag for yours. But you'd also need to tweak the CI/CD script to look at those branches for the release, as well.
