Bitcoinjs-lib: how do you validate a btc addressing using this?

[patoshii]

I couldn't find a function that validates a btc address. How can this be done? Thanks.

If you're generating an address using the library, then I'm sure it will only return a valid address, but if you want to add your own checks to it, here is a good resource:

bitcoin.addresses.fromBase58Check will throw if the provided address parameter is invalid.

Use bitcoin.addresses.toOutputScript if you also want to check the version byte for a valid script.
