How can i parse the signed tx ?

[bajian]

let txSignedBody = CardanoWasm.Transaction.new(
    txBody,
    witnesses,
    undefined // transaction metadata
);

let txSignedHex = Buffer.from(txSignedBody.to_bytes()).toString('hex');

console.log(txSignedHex);

I got the signed hex by the code above .
But i dont know how to parse and check the tx before broadcasting it .
Any method in this library or other cardano component to solve my question?

I found the /construction/parse api in the cardano-rosetta,but it seems not suitable for the sign in this format ?
Any bro can help me? Give me an example, thank you!

const tx = CardanoWasm.Transaction.from_bytes(
  Buffer.from(txSignedHex, 'hex')
);

const txBody = tx.body();
// etc.

Thank you. @vsubhuman

But how can i get the body as text type?

console.log(tx.body().inputs().get(0));
// TransactionInput { ptr: 1179800 }

I want to get the original address ,input and the mount

I want to get the original address ,input and the mount

Do you mean the address and the amount of inputs? Or address and amount of the outputs?

Yes. All of them. I want to check them before broadcasting to the node.

There's no export to JSON support in this library yet, you can only extract the required fields manually through the API methods.

The JSON support is planned to be added in the next version tho, and there's a PR for it. Around next week there probably will be a beta release of the next version with that change, so you will be able to try it out. Not until then, unfortunately.

Got it. Thanks a lot!
