Module not found : error : Can't resolve 'jquery' in node_modules\bootstrap\dist\js'

Using Base64EncodedStrings for images

3 min read

The images are in a legacy system (asp.net aspx pages). Some are generated dynamicly by that system (bar codes). The new system, mobile freindly, angualar, asp,net mvc requires to print docuements with these images in. So I get the content for the documents to be printed, and find it has img tags in it and these point to the relative path in the aspx application. 

I extract the relative path from the image tags, nice regex here. 

string imgTagSelectionPattern = @"<img.*?src=""(?<url>.*?)"".*?>";

Get the image and convert it to a base64encoded string

private string GetImageContentAsBase64EncodedString(Uri url)
{
    var content = string.Empty;
    try
    {
        var request = (HttpWebRequest)WebRequest.Create(url);
        using (var response = (HttpWebResponse)request.GetResponse())
        {
            if (response.StatusCode == HttpStatusCode.OK)
            {
                var receiveStream = response.GetResponseStream();
                if (receiveStream != null)
{
     byte[] outData;
     var tempMemStream = new MemoryStream();
     receiveStream.CopyTo(tempMemStream);
     outData = tempMemStream.ToArray();
     content = Convert.ToBase64String(outData);
}                  content = Convert.ToBase64String(outData);                 }             }         }     }     catch     {         //this is the base64 encoding of an 'image not found' image         content = "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";     }     return content; }

Then prepend it with the following "data:image/png;base64," replace the original src string with the new string and deliver all that client side in the new application.
