Cannot get the same address format from zeroMQ and Bitcoin Core

Question

I use nodejs with this npm library:

const bitcoinjs = require('bitcoinjs-lib');  // version "^5.1.6"

I received a rawTx from zeroMq, then extract it:

const tx = bitcoinjs.Transaction.fromHex(rawTx);

the txID is 8dba72608cbfca197b55d86aae2817d11f829b9361eb421fb005616f48ce8401

if I take the first output:

let output = tx.outs[0];

then I try to get the address:

const scriptBuffer = Buffer.from(output.script);
const address = bitcoinjs.address.fromOutputScript(scriptBuffer);

I get:

37XE9EYzix7S42fLMxutrNaPfDbCccLhiT

But from bitcoin core I get:

2My5SCyV2LQcnFpHt36XmUKZesZoNRQRPa5

My question: how do I convert the address to the same format as bitcoin core ?

You need to tell bitcoinjs to use the testnet settings – Raghav Sood Nov 05 '19 at 22:01 — Raghav Sood, Nov 05 '19 at 22:01
@Raghav Sood You should turn that into an answer. – Pieter Wuille Nov 06 '19 at 04:54 — Pieter Wuille, Nov 06 '19 at 04:54

Raghav Sood: you are right: here the correct code:

const addresses = bitcoinjs.address.fromOutputScript(outputScript, bitcoinjs.networks.testnet);

Thanks :-)
