I'm trying to go from seed phrase/mnemonic to payable address using BIP 44. Here is a simplified version of the code I'm using. However, when I compare with https://iancoleman.io/bip39/ the private, public, and address don't match up.

var mnemonic = require('bitcore-mnemonic')
var bitcore = require('bitcore-lib')

var code = new mnemonic("width bicycle axis tell burst outdoor tray episode where they forest meadow enhance twin focus");

var xpriv = code.toHDPrivateKey(bitcore.Networks.livenet);
var derived = xpriv.derive("m/44'/0'/0'/0/0")

var privateKey = derived.privateKey
var publicKey = derived.publicKey
var address = new bitcore.Address(publicKey)

console.log(`address: ${address}`)
console.log(`privateKey: ${privateKey}`)
console.log(`publicKey: ${publicKey}`)

This code outputs:

address: 14TomZRSGPtoPGy9HZA8WfX2veMbDXyAAJ
privateKey: 34fb6aee170bb41fe47f97ab601fea589620cf182ecf031688c25e5491c2c06f
publicKey: 027869eb83bbb44621c868fbd2a31daed4a0f8dbaa73d3fd79a597cdb1afcc9d1d

However when I go to https://iancoleman.io/bip39/ it give as the first address with this seed phrase to be:

path: m/44'/0'/0'/0/0
address: 1BogrbApan5Q9xEFEzwPioRu3ogYkzAQZU
public: 0236f0bf97fa766301e1137bef8377e6f6063b8a576bda57220c7ab6cf531cc992
private: L46hcht5ue2tsSKmPEV2v41CrGU8DEJAP1w7XYPbvJ72v5NBPsPF

When you say simplified code it's hard to tell where you are going wrong.

Here's an example of how you can derive a bip44 key pair from a mnemonic using bitcoinjs-lib v3.3.2

let mnemonicInput = 'width bicycle axis tell burst outdoor tray episode where they forest meadow enhance twin focus';
let seedHex = bip39.mnemonicToSeedSync(mnemonicInput).toString('hex');


let root = bitcoin.HDNode.fromSeedHex(seedHex);
let deriv = 44;
let account = 0;
let change = 0;
let index = 0;

let acct = root.derivePath("m/"+deriv+"'/0'/"+account+"'");
let xpub = acct.neutered().toBase58();
let pair = acct.derivePath(change+"/"+index).keyPair;

let wifkey = pair.toWIF();
let address = pair.getAddress();
