I have been trying to find it's alternative for hours now but lack of official documentation makes it difficult to find proper method

after going through number of issues i know that this function was deprecated or removed but what is its alternative ?

install v3 instead.

or update your code to use v4.

it is already v4 "bitcoinjs-lib": "^4.0.2",

[junderw]

update your code to use v4.

package.json is not code.

"update your code to use v4" means "stop using bitcoin.script.classifyOutput since it is no longer available in v4"

@mfaizan1 what is your use case for classifyOutput?

There is no 1:1 exact replacement for classifyOutput.

Please show us some code and for what you are using classifyOutput.

Most likely you can accomplish the same goal with the payments API.

var decodeOutput = function(tx){

    var format = function(out, n){
        var vout = {
            satoshi: out.value,
            value: (1e-8 * out.value).toFixed(8),
            n: n,
            scriptPubKey: {
                asm: Btc.script.toASM(out.script),
                hex: out.script.toString('hex'),
                type: Btc.script.classifyOutput(out.script),
                addresses: [],
            },
        };
        switch(vout.scriptPubKey.type){
        case 'pubkeyhash':
        case 'scripthash':
            vout.scriptPubKey.addresses.push(Btc.address.fromOutputScript(out.script, Btc.networks.regtest));
            break;
        }
        return vout
    }

    var result = [];
    tx.outs.forEach(function(out, n){
        result.push(format(out, n));
    })
    return result
}

"bitcoinjs-lib": "^4.0.2",

• Quick 'dirty' fix : bitcoin.script.classifyOutput = require('./node_modules/bitcoinjs-lib/src/classify').output;

Please don't

Did you ever get this figured out IC nobody answered you. I have same question.

@mfaizan1 , @mmvphil I fixed decodeOutput function to align with the latest bitcoinjs-lib version. Please refer to https://github.com/bitcoinjs/bitcoinjs-lib/issues/760#issuecomment-1692806359.
