How to decode an unsigned transaction using polkadot.js

Question

If I have some unsigned transaction, eg 0x040300865ea... and I wanted to decode it into a format like:

method: "balances",
section: "transfer":
...

Is there a way to do that using polkadot.js or similar library? Most of the information I've come across describes the SCALE codec itself.

Answer 1

The api provides a shortcut helper for this - api.tx(<hex bytes>) will decode/reconstruct it.
