Is this an assertion for a canvas element? Or for a fabric Object? Or both?

[asturur]

everywhere else we use the promise syntax, let's leave that one

Migrate Pattern to TS I thought it had default values in export, that's why I left it but it doesn't so I migrated it.

it could have them :) but patterns are usually small.

This is fine for where we are at.
The issue with TS and Classes and that it makes harder to add whatever i want to an object ( shadow, fabricObject, pattern gradient ) and export/import it.

Types makes it hard at dev time, classes makes it hard at runtime.

Now Patterns and Gradients are usually not really where people add businnes logic ( names or special props or special behavior ) so those are fine to be standard classes, with or without the default values issue
