With the current state of web apps, we can rely on various UI elements to interact with users. With the Web Speech API, we can develop rich web applications with natural user interactions and minimal visual interface, using voice commands. In this tutorial, Tomomi Imura will use the API to create an artificial intelligence (AI) voice chat interface in the browser. The app will listen to the user’s voice and reply with a synthetic voice. Because the Web Speech API is still experimental, the app works only in supported browsers. The features used for this article, both speech recognition and speech synthesis, are currently only in the Chromium-based browsers, including Chrome 25+ and Opera 27+, while Firefox, Edge and Safari support only speech synthesis at the moment.

In this article, Owais Afaq gives you hands-on access to his journey of creating a digital assistant capable of connecting with any system via a RESTful API to perform various tasks. He will create a chatbot using Node.js and Microsoft’s Bot Framework SDK; send the data collected from the user to an API; set up both local and server environments; and deploy it live on dev.botframework.com. In part 2 of this series, you’ll learn how to add natural language processing using LUIS to make our chatbot intelligent enough to understand human language and to extract information from a user’s utterances.

Mad Libs is a game in which one player prompts others for a list of words to substitute for blanks in a story, before reading the story aloud. In this article, Tom Hudson will use this game to show you how to build your own action for Google Home. He’s detailed steps to build a custom mad lib action, and He’ll explain why certain steps are important and ultimately how they fit into the voice services world. After this exercise, you will better understand voice services and begin your path to programming actions for Google Home.

For every application Yury Dymov works on, he needs to decide how to manage the data. The problem can be broken down into the following three subproblems: Fetch data from the back end, store it somewhere locally in the front-end application, retrieve the data from the local store and format it as required by the particular view or screen. In this article, Yury sums up his experience with consuming data from JSON, the JSON API and GraphQL back ends, and it gives practical recommendations on how to manage front-end application data.

Imagine an archaic, alien workflow, with ancient tooling, and none of those things you love about the web. How would your career be affected? As a web developer, not only do you already possess all of the skills to make great modern desktop apps, but thanks to powerful new APIs at your disposal, the desktop is actually where your skills can be leveraged the most. In this article, Adam Lynch will look at the development of desktop applications using NW.js and Electron, the ups and downs of building one and living with one, using one code base for the desktop and the web, and more.

After building several client websites, ranging from small cafés to growing startups, Stefan Judis figured out that the holy WYSIWYG editor is not always the silver bullet we’re all looking for. These interfaces aim to make building websites easy, but there are always more use cases for your content on different platforms. In this article Stefan Judis will show you what he built and how his website surprisingly turned out to be his daily companion.

One of the upcoming features of JavaScript that I especially like is the support for asynchronous functions. In this article, I would like to show you a very practical example of building a server-side application using Koa 2, a new version of the web framework, which relies heavily on this feature.
First, I’ll recap what async functions are and how they work. Then, I’ll highlight the differences between Koa 1 and Koa 2. After that, I will describe my demo app for Koa 2, covering all aspects of development, including testing (using Mocha, Chai and Supertest) and deployment (using PM2).
