BUILD CHAT APPS FAST
This is a basic chat example. The code to the left, you can build realtime chat in 10 lines of JavaScript - just copy and paste the code into your favorite text editor and save as a .html.
Send and Receive Messages
Tasks like sending and receiving data through PubNub take a single function call. The basic “send” functionality happens through a publish() call.
And to “receive” all of the sent messages on a specific channel, simply make a subscribe() call. All of the network infrastructure and scaling is taken care of for you, so you spend time building your app, not the infrastructure.
DEVELOP CHAT ACROSS PLATFORMS
PubNub empowers you to build cross-platform, supporting chat for mobile, browser, desktop, server, and even the Internet of Things. Build in one language, extend to every device!
