Attribute-hooks

Support for style diffing (setting style to an object value) was removed, and there is currently no way for a library to add it back in.

As discussed here this could be solved by reconsidering support for modularity, which was previously proposed in #86. (this PR is outdated, and the approach is probably wrong, see below.)

Note that the approach in that PR was based on use a global registry, which should be avoided, as discussed in the comments above.

Needs a detailed proposal, but one idea is to make this feature available via currying to avoid global state. You would get a default instance of the render function with only the built-in attribute-handlers - as well as a factory-function, which you could use to generate another instance of render with additional attribute-handlers registered in the instance of it, to avoid global state and side-effects.

For example:

import * as ultradom from "ultradom";

export const render = ultradom.render.with({
  style: (el, value, oldNode, newNode) => {
    // diff and apply style properties
  }
});

That’s just an idea - this needs a more detailed proposal.

Style support is back.

And now it’s gone again. 😏
