Agora RTM test on Angular 11

We needed a new video chat application that will replace the existing XMPP server and found Agora.io as suitable substitute. While migrating from nodejs to Angular, I encountered some conversion issues for token generation.

Nodejs crypto:  crypto.createHmac is not a function

var encodeHMac = function (key, message) {

    return crypto.createHmac('sha256', key).update(message).digest();

};

solution:

var encodeHMac = function (key, message) {

    return crypto.HmacSHA256(message, key)

};

Error:  "TypeError: The first argument must be one of type string, Buffer, ArrayBuffer, Array, or Array-like Object. Received type object"

var AccessTokenContent = function (options) {

    options.pack = function () {

        var out = new ByteBuf();

        return out.putString(options.signature)

            .putUint32(options.crc_channel)

            .putUint32(options.crc_uid)

            .putString(options.m).pack();

    }

    return options;

}

solution:  

var AccessTokenContent = function (options) {

    options.pack = function () {

        var out = new ByteBuf();

        return out.putString(options.signature.words)

            .putUint32(options.crc_channel)

            .putUint32(options.crc_uid)

            .putString(options.m).pack();

    }

    return options;
