What's New For Plugins In Sketch 40?

Sep 26, 2016

Scripting API

With the release of version 40 of Sketch, we’re slowly moving towards rolling out our Javascript API as a better way to work with the Sketch model from within your plugins.

As part of this work, we’ve updated this site to include an API Reference section.

The API itself is still under development, and should not be regarded as completely fixed or ready for prime-time.

It’s getting there however, and if you’re starting to work on new plugins, you may want to consider trying it out.

Over the next few releases we’ll be developing the API further, updating all of our existing plugin examples to use the API, and also adding some new examples.


With the next version of Sketch, we’re planning on fully adopting a change that Apple made a while ago known as App Transport Security. This relates to the security of HTTP connections, and requires that all such requests be made using https: and not just plain http:.

Until now we’ve disabled this feature, but soon we will enable it.

Unless your plugin requests content from web pages, it should be unaffected by this change.

If however you do fetch data or resources from web pages, you will need to change over to using https: in your URLs.

We also suggest that everyone changes to using https: for any URLs specified in the plugin’s manifest file. Future versions of Sketch may use these URLs.

Not a developer? Submit an idea

If you don’t have the programming experience to create your own Sketch plugin or integration, you can submit an idea to let our team and the community know what kind of functionality you’re looking for.

Take a look at the list of plugins the community has already built.
