Twixl Publisher lets you use different content types in your app.
In addition to InDesign-based content created with the Twixl Publisher plug-in, or PDF files, you can now also publish HTML articles. HTML content can be created as standalone articles, but in many cases HTML content will be pushed from a solution like e.g. WoodWing Inception, WoodWing Aurora/Studio, Canvasflow.
You can combine InDesign, HTML and PDF content within the same app.
Working with InDesign content
For detailed information on how to create your interactive InDesign content, check this chapter.
For single articles, you'll export one document using the Twixl Publisher InDesign plug-in. This file will have the extension .article. If you zip the .article, you'll be able to upload it for inclusion in your app.
You can also import complete Twixl .publication files exported from InDesign: in your app on the platform, select a collection, and at the top an option "Import publication" will be available. When you upload the zipped .publication, it will then be processed and automatically split into separate .article content items.
Working with HTML content
HTML content can be created manually, using such tools as Adobe Animate or Tumult Hype, or can be pushed from an external source.
Zip only the documents and not the complete folder for an article, as in that case the index.html cannot be found at the root level.
Working with PDF content
Plain PDF files can be uploaded for inclusion in your app. Make sure to prepare the PDF according to the instructions in a this article.
