@chadoh can you add a changelog entry? |
Before ContractClient lived in stellar-sdk, we allowed (the equivalent
of [[1]]) setting `publicKey` to `undefined`.
This is handy, if you're trying to get the result of view calls and you
only need the simulation. Our main onboarding tutorial assumes that we
have this functionality, and it definitely makes for a more incremental
build-up of mental models about how Soroban and Stellar work.
While making ContractClient, we thought maybe this added unnecessary
complexity to the interface, and further thought people would be able to
pass `Keypair.random()` if they wanted a fake account.
The trouble with the `Keypair.random()` approach is that the call to
`server.getAccount` fails, because the account has not been funded.
We _could_ fix this by doing:
let account: Account;
try {
account = tx.server.getAccount(options.publicKey)
} catch () {
account = new Account(options.publicKey, '0')
}
But this seems clumsy. Even if there's a better way to check that the
caught error is the error we expect (`{ code: 404, message: 'Account not
found' }`), why allow passing a publicKey if it's actually ignored? It
seems like a clearer expression of intent to allow the publicKey to be
`undefined`.
