public static class JavaScripMinifier
    private const string URL_JS_MINIFIER       = "https://javascript-minifier.com/raw";
    private const string POST_PAREMETER_NAME    = "input";

    public static async Task<String> MinifyJs(string inputJs)
        List<KeyValuePair<String, String>> contentData = new List<KeyValuePair<String, String>>
            new KeyValuePair<String, String>(POST_PAREMETER_NAME, inputJs)

        using (HttpClient httpClient = new HttpClient())
            using (FormUrlEncodedContent content = new FormUrlEncodedContent(contentData))
                using (HttpResponseMessage response = await httpClient.PostAsync(URL_JS_MINIFIER, content))
                    return await response.Content.ReadAsStringAsync();


using (Task<String> task = JavaScriptMinifier.MinifyJs("/* comment */ console.log( 1 );   "))
    Console.WriteLine(task.Result); // input{font-size:9pt}

C# Example

Thanks to Juan Herrera for contributing this example.

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://javascript-minifier.com/raw");
request.Method = "POST";
string formContent = "input=" + jsContent.Text;
byte[] byteArray = Encoding.UTF8.GetBytes(formContent);
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;

Stream str = request.GetRequestStream();
str.Write(byteArray, 0, byteArray.Length);

WebResponse response = request.GetResponse();
str = response.GetResponseStream();
if (str != null)
  StreamReader reader = new StreamReader(str);
  jsMinified.Text = reader.ReadToEnd();
