Last spring our superhero intern Martin (now a full time member of Team PubNub) created a comprehensive blog series on building a full featured chat app with Angular JS. Along the way he completely overhauled the PubNub Angular SDK and paved the way for Angular 2. Here it is, your complete guide to building...

Good News! We’ve launched an all new Chat Resource Center. We recommend checking out our new Chat Resource Center, which includes overviews, tutorials, and design patterns for building and deploying mobile and web chat. Take me to the Chat Resource Center → Building chat applications is easier...

Welcome back! In the previous article, we explored smart home automation via a garage door opener service using LiftMaster, PubNub, and Node.js. The context is the growing popularity of two main areas, the Smart Car and Smart Home. Integration of Smart Home door and access control seems like a natural...

Have you ever wanted to design your own programming language? It seems like such fun, but if you’ve ever tried you probably got stuck right around the time you read “LLR Decent Parsers and Abstract Syntax Trees.” Traditionally designing your own language was hard because it requires a very specialized...

This blog is based on my talk from NodePDX 2016. You can watch the full video of my session, or read my other writings on my personal blog. Today I’m going to build a casual Massively Multiplayer Online game. Something that can have 50 or more people playing at the same time. And I’m going to do...

Household appliances are not the kind of thing consumers really get excited about; they’re no iPhone. But thanks to the Internet of Things (IoT), that seems to be changing. It is now easy, inexpensive, and a lot more fun to create connected devices in every area of life, from cars and homes to...

In the three previous posts in this series, we learned how to use Ohm to parse numbers, build an expression tree, and process blocks of code with conditionals. In this final post on the Ohm series, we will finish up our complete programming language, Meow, with looping and real function calls. Thanks...

Welcome back! In our first Ohm post, we introduced Ohm and built our very own parser to handle numbers in various formats. In our second post, we turned our parser into a real arithmetic language with binary operations and symbols. Today we will give our language code blocks and conditionals.  ...

Middleware Functions, a new feature of the PubNub Data Stream Network that lets you move computation into the network itself, allowing your apps to go completely serverless. Check how Functions work. How does it secure potentially un-trusted code? How does it keep one app separate from another? How does...
