Use base64 encode/ decode on client and server. All the web browsers with WebSockets have window.atob (base64 decode) and window.btoa (base64 encode). The WebSockets server has base64 libraries.To transfer binary data, you would be working with wsproxy included with no VNC that is a web based VNC client.The wsproxy is a WebSockets to generic TCP sockets proxy. The base64 encodes/decodes all traffic to/from the browser. Use it to connect from a WebSockets capable browser to any type of TCP port.

Local Storage is designed for storage that spans multiple windows and lasts beyond the current session. In particular, Web applications may wish to store megabytes of user data, such as entire user-authored documents or a user's mailbox, on the client side for performance reasons.For storing credentials in local storage, on successful login, generate a completely random string unrelated to user credentials. You need to store this in the database. Do not forget to add an expiry date. Pass that string to the JavaScript to be stored in local storage.As long as the local storage credential matches the database and the ... Read More

Amazon S3 now supports cross-origin resource sharing so HTML5 uploads are now possible.Before it was not possible. Plupload can be directly uploaded to HTML5 by cross-origin resource sharing (CORS).With the help of CORS (Cross-origin resource sharing), rich client-side web applications can be created.It selectively allows cross-origin access to S3 resources with the help of which we can access Amazon.

When making HTML5 web application using KineticJS, grouping, and layering need to be used.Groups are basically containers whereas layers are separators basically.The group is a container which is having shaped objects inside layers for ex group might contain both circle and rectangle.If a group is manipulated then elements within that group is also manipulated.ex if we drag the group then its elements get dragged as well.However, layers actually separate canvas elements that are at the top of one another. This is quite similar to the layers that work in Photoshop and Illustrator. Multiple layers are visible simultaneously.Layers are used to ... Read More
