Build An Alexa Skill With Golang And AWS Lambda

It has been a few years since I last worked on and published an application, otherwise known as a Skill, for Alexa powered voice assistants. My last Skill titled, BART Control, was built out of necessity because of my commuting on the Bay Area Rapid Transit system. While I didn’t open source it, I had created the Skill with Node.js and a publicly available BART web service. Since then I had written a tutorial titled, Create an Amazon Alexa Skill Using Node.js and AWS Lambda, which also focused on Node.js.

I’m a huge fan of Golang and was pleased to see that AWS Lambda recently started to officially support it. AWS Lambda isn’t a requirement to creating Alexa Skills, but it is a huge convenience. To make things even better, Amazon recently sent me an invitation to take part in their developer offer to receive an Amazon Echo Show for publishing another Skill. The offer and Golang inspired me to develop another Skill and this time I wanted to share my process.

Parse XML Data In A Golang Application

While I don’t see a lot of it anymore, XML is still a common data format that people use. I prefer JSON, but I don’t always have a say in how I receive data. Some time ago I wrote a few tutorials on which include parsing XML data with Node.js, parsing XML data with Java, and parsing XML data with PHP. If you’ve been keeping up, I’ve been doing a lot of development with the Go programming language which is why I think it would be a great idea to go over XML in Golang.

Of the various programming languages, I think XML is the easiest to work with in the Go programming language. We’re going to see how to take XML data and unmarshal it into a custom structure. We’re also going to see how to take JSON data and convert it into XML.

Build An RSS Reader Mobile App With Ionic 2 And Angular

If you’re a long time follower of my blog you’ll remember I wrote an article about creating an RSS reader using Ionic Framework. That tutorial not only used the first version of Ionic Framework, but it now also uses a deprecated Google service, once known as the Google Feed API. Because of the deprecated API, it no longer works.

I still get a lot of people asking me about the creation of RSS readers, so I figured it was time to come up with a new solution. With Ionic 2 being all the rage, it makes sense to explore feeds with this version of the framework.

Here we’ll be building an RSS feed reader for Android and iOS using Ionic 2 and Angular with TypeScript.

Create A Podcast XML Feed For Publishing To iTunes

Recently I started a developer podcast, but more work went into it beyond just recording it. I had to create an XML feed file to be published to iTunes as well as Pocket Casts.

I figured it would be nice to share what goes into creating an XML feed, how to validate it, and how to submit it to iTunes as well as the popular Pocket Casts.

Parse An XML Response With Java And Dom4J

Previously we’ve explored how to parse XML data using Node.js as well as PHP. Continuing on the trend of parsing data using various programming languages, this time we’re going to take a look at parsing XML data using the dom4j library with Java.

Now dom4j, is not the only way to parse XML data in Java. There are many other ways including using the SAX parser. Everyone will have their own opinions on which of the many to use.

Parse An XML Response With Node.js

A while back I wrote an article on how to parse XML using PHP. Since then I’ve slowly been transitioning away from PHP, yet XML continues to be a burden that I can’t get rid of.

Not all APIs return JSON so it is the application developers responsibility to handle the XML. Lucky for us there is a convenient package for Node.js called xml2js that will handle all the parsing for us.

Parse An XML Response With PHP

If you’re like me, you find XML a real pain to deal with, but yet it still seems to exist with various web services. If you’re using Android or AngularJS, these frameworks can’t process XML out of the box, but they can JSON.

With the assistance of a PHP powered web server, you can easily transform the nasty XML responses you get into something more usable like JSON.
