Manage and Preview APL Documents in Visual Studio Code

---

You can use the Alexa Skills Kit (ASK) Toolkit for Visual Studio Code (VS Code) to create, edit, and preview Alexa Presentation Language (APL) documents for your skills. The ASK Toolkit for VS Code is an extension that makes it easier for you to create, test, and deploy Alexa skills. For prerequisites and installation instructions, see Get Started with the ASK Toolkit for VS Code.

Overview

With APL you can create visual experiences to accompany your skill. Users can see and interact with your visual experiences on supported devices such as the Echo Show, Fire TV, some Fire tablets, and other devices. You can include animations, graphics, images, slideshows, and video in your visual experience. For details, see Add Visuals and Audio to Your Skill.

The following screenshot shows the APL Preview page in the Visual Studio Code IDE:
