Introducing TCP Listen, a new API for Chrome packaged apps
venerdì 2 novembre 2012
Chrome packaged apps
aim to deliver an app experience with the appearance and capabilities of native apps, but built using the growing capabilities of HTML5. These apps can access APIs for better filesystem handling, direct access to hardware devices, raw network communication and
many others
. One of the new APIs that just landed in an experimental state is
TCP Listen
, which allows an app to accept incoming TCP connections.
Since the developer preview launch
earlier this year
, Chrome packaged apps have been able to connect to remote servers using TCP or UDP, and bind to a UDP port. For example, this
Media Center application
searches for and connects to media servers in the local network. Now, through the new TCP Listen API, a Chrome packaged app can also act as a TCP server itself and accept incoming connections on specified ports.
You can use this API, for example, to create a
HTTP server
on a development environment application, to
automate a browser window
for page load testing (see image below) or even to augment the
Media Center application
with a
DLNA®/UPnP
media server and show your PicasaWeb pictures on your DLNA® enabled television.
To get started, clone this
GitHub repository
and look at the
webserver
and the
TCP server
samples. You may also want to watch the
Chrome Apps Office Hours
where we specifically talk about the TCP Listen API.
We are curious to see what clever ideas you will come up with. Have questions or comments? Subscribe to
