Pass all SVG attributes through #5714

gaearon · 2015-12-22T20:20:13Z

Update: this was reverted in favor of a different approach in #6243.

If any attribute is missing please file an issue and we'll add it.

All attributes defined on SVG elements will now be passed directly regardless of the whitelist.
The casing specified by user will be preserved, and setAttribute() will be used.

In the future we will remove support for the camel case aliases to the hyphenated attributes. For example, we currently map strokeWidth to stroke-width but this is now deprecated behind a warning. When we remove support for this, we can remove some of the code paths introduced in this commit.

The purpose of this change is to stop maintaining a separate SVG property config.
The config still exists for two purposes:

Allow a migration path for deprecated camelcased versions of hyphenated SVG attributes
Track special namespaced attributes (they still require a whitelist)

However it is no longer a blocker for using new non-namespaced SVG attributes, and users don't have to ask us to add them to the whitelist.

Fixes #1657

This seems good.

Can we make the warning here SVG-specific? Maybe "SVG attribute clipPath is deprecated; use the original attribute name clip-path for SVG tags instead."
Instead of a new "deprecated" flag, can we just compare the attribute name in createMarkupForSVGAttribute and warn if it's different (and there's no namespace)? If I'm missing some reason that won't work, this way is fine too.

I thought I had a third thing too but I forget now.

Amended the commit based on your comments. I added a completely separate code path for the SVG warning so it's easy to remove later and we don't have to think about getPossibleStandardName being broken in this case.

One thing that concerned me is whether I should add new DOMPropertyOperations methods to

ReactPerf.measureMethods(DOMPropertyOperations, 'DOMPropertyOperations', {
  setValueForProperty: 'setValueForProperty',
  setValueForAttribute: 'setValueForAttribute',
  deleteValueForProperty: 'deleteValueForProperty',
});

at the bottom.

nit: 2 space indent (you have a couple of this exact 2 lines doing the same thing - maybe have a helper method?)

I was trying to follow the existing style in this file.

Here are a few places I haven't touched where indentation is the same as mine, and they also don't bother to extract the helper function:

https://github.com/gaearon/react/blob/013340a44dbf99e5855962e68688453eab324f5f/src/renderers/dom/shared/DOMPropertyOperations.js#L159-L160

I'm happy to re-indent all of them at once and add a helper for getting the property, if you'd like! Just wanted to avoid introducing inconsistencies. Also I didn't want to overgeneralize because this code will later be likely removed when we kill the deprecation path and just start treating SVG pretty much like custom components.

Ok, let's just leave it as is then 👍

I updated the PR to merge cleanly on top of #5590 but unlike #5590 it still uses the old warning system.
I'll look into updating this PR to use devtool but this can be done separately.

In #5590 a new system was introduced for tracking dev-time warnings. This commit uses it for reporting SVG attribute deprecation warnings.

gaearon · 2015-12-24T17:54:03Z

I moved the warnings into a separate devtool to align with #5590.
I'm adding @jimfb to reviewers so he can evaluate whether I'm using it correctly.

Did you mean for this to be above the previous case? I think it works out the same either way, so I guess it doesn't really matter.

This was reverted, so could the OP be updated to reflect that? Lots of issues for SVG point to this one, it confused me before more googling led me to #6243
