How to get BTC transfer amount from raw tx using bitcoinjs
The transfer amount (BTC) is, (somewhat dependant on the library used),  most commonly denominated as "value:"
Read: the outs => value: *

 {
      value: 1000000,
      script: &lt;Buffer a9 14 14 ea 69 2e 87 76 ec c6 2e 6a aa a1 7d cc d2 8f f3 30 b7 46 87&gt;
    },
    {
      value: 3299775,
      script: &lt;Buffer a9 14 73 e2 99 78 43 31 1e cc 32 b5 ac 38 ef c9 9b b3 ae 54 bc 7c 87&gt;
    }


Where the value is most often denominated in satoshis (a single unit.). But, some block explorers (blockchair) or other libraries will denominate in single units of Bitcoin, as is done below. (10^8 satoshis - 1 BTC ( 100 mil))

1000000 = 0.01BTC
3299775 = 0.03299775 BTC
