WebSocket Support

Starting with Version 1.0.6, NS Basic/App Studio supports web sockets. WebSockets define a full-duplex single socket connection over which messages can be sent between client and server. The WebSocket standard simplifies much of the complexity around bi-directional web communication and connection management.

It’s also easy to use from NS Basic. The new release has a sample client app that runs on the device, as well as a desktop server sample. It’s all explained in the new Tech Note, WebSockets.

NS Basic/App Studio 1.0.4 released

NS Basic/App Studio 1.0.4 is ready to download. You can download it from the same URL as before.

This update has both fixes and some new stuff. Here they are:

  1. Code Window: And and Or now properly highlighted.
  2. Code Window: InStr fixed.
  3. Docs: Handbook and Language Reference updated.
  4. IDE: Form has new function: submit(). See Docs below.
  5. IDE: Form has new property: URL. See Docs below.

The big news in this release is the new SendData sample. It shows how you can collect data on a form, send it to a server, and receive a reply from that server. It’s surprisingly simple. You can start digging into the sample right away: we will be publishing documentation explaining how it works as soon as we can.

Cache Events

One of the cool features of NS Basic/App Studio is that apps can be installed to the Home screen and run even if the device is offline. It does this by caching the files the app uses.

There have been some questions about how offline apps get cached: how do you tell if you app is being updated with a fresh copy?

It turns out there are some nice events you can watch. You could use these to put up a progress dialog, or a warning to wait until the update is complete. The events only appear if you are downloading a deployed version – they do not fire if you are running locally.

Here’s the important code – a good place to put it is in the global code section.

window.applicationCache.addEventListener("checking", logEvent, false)
window.applicationCache.addEventListener("downloading", logEvent, false)
window.applicationCache.addEventListener("noupdate", logEvent, false)
window.applicationCache.addEventListener("progress", logEvent, false)
window.applicationCache.addEventListener("updateready", logEvent, false)

Function logEvent(e)
  print e.type
End Function
