PSPDFKit for Web 2021.4 Adds Undo and Redo and Document Editor Customization

Today we’re thrilled to introduce PSPDFKit for Web 2021.4! In this release, we’re adding undo and redo capabilities to the SDK, extending the customizability of our Document Editor UI, improving our TypeScript support, and so much more!

Undo and Redo Support

Our latest feature consists of full undo and redo capabilities. There are new toolbar controls available to allow users to discard and reapply their performed actions. In addition to the toolbar controls, we included support for the standard keyboard shortcuts for undo and redo as well.

You can also programmatically control the actions history via new dedicated APIs. Please check out our Undo and Redo guide to learn more about integrating undo and redo on PSPDFKit for Web.

If you’re curious about our experience when implementing this feature, we shared many technical details about our journey and choices in our Approaches to Undo and Redo blog post.

Document Editor Customization

It’s now possible to customize the UI for both the toolbar and footer of the Document Editor. You can adjust the appearance of existing items, add custom ones, or change their order.

Please check out our Customized Document Editor example for a glimpse of what’s possible. You can also read our Customizing the Document Editor Toolbar and Footer guide to learn more about how to implement these customizations.

Improved TypeScript Support

TypeScript continues to increase in popularity with JavaScript developers, and here at PSPDFKit, we decided to embrace it internally in our products, including PSPDFKit for Web.

As a result, this release ships with revamped TypeScript type declarations so that you can integrate PSPDFKit into your TypeScript applications with more reliable type guarantees at compile time and improved autocomplete support for our APIs.

And More

This release also includes numerous bug fixes and minor improvements. For a complete list of changes, see the PSPDFKit for Web 2021.4 and PSPDFKit Server 2021.4 changelogs, as well as the migration guides for PSPDFKit for Web 2021.4 and PSPDFKit Server 2021.4.
