To convert large binary to hex use this code

const binaryData:=
{
    '0000': '0',
    '0001': '1',
    '0010': '2',
    '0011': '3',
    '0100': '4',
    '0101': '5',
    '0110': '6',
    '0111': '7',
    '1000': '8',
    '1001': '9',
    '1010': 'A',
    '1011': 'B',
    '1100': 'C',
    '1101': 'D',
    '1110': 'E',
    '1111': 'F',
};

export function binaryToHex(bin: string)
{
    let hex = '';

    for (let i = 0; i < bin.length;)
    {
        hex = hex + binaryData[bin.substr(i, 4) + ''];
        i += 4;
    }

    return hex;
}

Catch: Input should be multiple of 4. Else prefix with zeros.

export function binaryToHex(bin: string)
{
    // prefix zeros
    const missingZeros = 4 - bin.length % 4;

    bin = '0'.repeat(missingZeros) + bin;

    let hex = '';

    for (let i = 0; i < bin.length;)
    {
        hex = hex + parseInt('' + bin.substr(i, 4), 2).toString(16);
        i += 4;
    }

    return hex;
}
