RangeControls: Improve UI + UX #19916

ItsJonQ · 2020-01-27T17:56:22Z

Description

This update improves the UI and UX for the RangeControl component with @wordpress/components.

Features ✨

Visual tooltip that displays current value (Tooltip). Follows the "thumb" (circle)
Larger hitbox, making it easier to click/drag
More consistent UI between slider, input, and Reset button
Renders step markers with a simple + custom prop (marks)
Tooltip auto positions top or bottom, based on ideal rendering position
Can easily change the color of the "track" using a color prop
Can customize the tooltip's content with a custom renderProp
Ability to show/hide the accompanying input[type="number"]

Example of step marks + Tooltip rendering:

A11Y Considerations 💪

Uses native input[range] under the hood, which gives us native keyboard interaction handling
Uses aria roles on elements to emphasize changes / reduce noise (via aria-hidden)
Respects reduce-motion to disable all animations

Other Considerations ✌️

RTL support
README file has been updated with additive API changes

How has this been tested?

This update was developed within Storybook. When ready, it was integrated and tested with Gutenberg, local dev.

Voiceover

This component was tested with Mac OS Voiceover, to ensure the value change announcements + keyboard interactions worked as expected.

Mobile

Although, this component only updates the Web version, the changes were tested on both iOS (iPhone 8) and Android (Samsung A50)

iPhone 8 Screen Recording

Note: The inputMode for the number input was set to decimal, which allows for the numpad keyboard to appear for mobile.

Types of changes

CSS

The CSS for the updated component was written with Emotion, leveraging the new/experimental CSS-in-JS system.

Tooltip

The Tooltip that appears to indicate the value is not a @wordpress/components one, but rather, a simple/custom implementation.

Reason

I had originally tried using the Popover/Tooltip from @wordpress/components, but this led to (perceived) performance rendering issues:

https://d.pr/i/a6i3R4

The positioning render cycle was not in sync with the quick changes, which made the experience look and feel really laggy.

As a work-around, I created a simple Tooltip which is currently only being used in the new RangeControl component. (I'm open to changing this approach if anyone has suggestions)

Backwards Compatibility

This update preserves all of the Component APIs. Therefore, it shouldn't break backwards compatibility. It passes all of the previous unit tests and appears to be working as expected when testing within Gutenberg. Component API changes are additive.

This is great! A few pieces of feedback to talk about and then happy to review.

Could we have no shadow perhaps as I'm not sure we had before on the circle?
Are we able to increase the size of the arrows on input, I would love that to be bigger.

Also test integration with Gutenberg

Also add comments for hooks and functions

ItsJonQ · 2020-01-29T14:27:55Z

@karmatosed Haii!

Could we have no shadow perhaps as I'm not sure we had before on the circle?

Shadow removed. In doing so, I noticed that there was barely any visual feedback to indicate a focus state. I've adjusted it so that the circle has a blue ring (similar to input fields) when focused:

Are we able to increase the size of the arrows on input, I would love that to be bigger.

That input field is currently using an out of the box number input. How they render is based on your browser x OS.

To make the arrows bigger, we'd need to do quite a bit of custom UI/CSS work. In which case, I'd advise perhaps updating the base TextControl to support this (in a separate PR).

Hope that makes sense!

I did a quick search and I noticed that it's only used in FontSizePicker.
Maybe we can just move the style there and rename the class to follow our guidelines components-font-size-picker__number

Sounds good to me! I'll do that now

youknowriad

LGTM 👍 Thanks for your hard work here.

Rename rangeControl related ID and classNames to match the structure of FontSizePicker

@youknowriad

Module cssjanus has an incompatible license 'Apache-2.0'

Aww. Does that mean we can't use this package?

ZebulanStanphill · 2020-02-06T20:11:46Z

Just to clarify, Apache 2.0 is compatible with GPLv3, but not earlier versions of the GPL. WordPress is GPLv2+ (which means it could legally switch to GPLv3+ to use this library, but dropping GPLv2 compatibility is probably not a reasonable option here).

If you really want to use this particular library, you could ask the library contributors (there are 12 of them) to consider relicensing or dual-licensing under a license compatible with GPLv2+.

ItsJonQ · 2020-02-06T20:20:00Z

@ZebulanStanphill Thanks for your insight! I'm going to explore alternative solutions now

ItsJonQ · 2020-02-06T21:04:13Z

Updates! I took a look at various solutions, and nothing seemed to feel right. I've opted to remove cssjanus, and wrote a tiny albeit naively simple and basic utility.

cc'ing @youknowriad and @aduth for thoughts!

(Sidenote: My Regex game is quite weak 😂 . Please feel free to improve the implementation!)

It's definitely not as seamless as cssjanus or the postcss auto-generated workflow.
I can see this working short term... but would definitely love something better for the long term.

youknowriad · 2020-02-07T07:37:27Z

Looks like there's some valid e2e test failures.

ItsJonQ · 2020-02-07T15:11:18Z

@youknowriad Ah. Looks like I need to update the E2E selectors for FontSizePicker, since we renamed them

By updating the className for the input number field

ItsJonQ · 2020-02-07T20:30:56Z

Yay! E2E is fixed 😍

If it's a common use case that the label would be the same as value, could we make it optional and fall back to a stringified value?

I'm not sure if it's common yet :).
I can see cases where you may want to render '10%' instead

Would be good to describe the default here, since it might be unexpected that the default is true (that it's an opt-out, not an opt-in).

We could have dropped compose here rather easily, as it really only provides value when composing multiple:

export const RangeControlNext = compose( withInstanceId )( BaseRangeControl );

export const RangeControlNext = withInstanceId( BaseRangeControl );

I see it's not really documented anywhere (other than "when in doubt, space it out"), but: I would expect this should be formatted as:

Suggested change

${ markFill };

@jsnajdr Is this something we should/can integrate into wp-prettier?

Edit: Now I'm confused, because I see the expected spacing in another example below. Is this something that Prettier doesn't have opinions about?

It's a template string with backticks, isn't it? Then Prettier should have an opinion here and should do the `${ spaced }` formatting.

@jsnajdr That's what I would expect as well, but it does not appear to be working correctly.

It looks like a bug in wp-prettier. If the template literal is a styled component, with the styled.span tag, it's treated specially. Thanks for finding and reporting!

I created a wp-prettier fix in this commit: Automattic/wp-prettier@01fd780

A fix was needed for all the template literals that have a recognized format (CSS, GraphQL, HTML...) and where the string itself is being formatted.

I usually release such patches when a new upstream version comes out. In this case, I'll be waiting for prettier@1.19.2.

Can we create an issue to track this technical debt?

+/**
+ * An incredibly basic ltr -> rtl converter for style properties
+ *

+ * @return {Object} Converted ltr -> rtl styles

+	const nextStyles = {};
+
+	for ( const key in ltrStyles ) {
+		const value = ltrStyles[ key ];
+		let nextKey = key;
+		if ( /left/gi.test( key ) ) {
+			nextKey = [ key.replace( 'left', 'right' ) ];
+		}
+		if ( /Left/gi.test( key ) ) {
+			nextKey = [ key.replace( 'Left', 'Right' ) ];
+		}
+		nextStyles[ nextKey ] = value;
+	}
+
+	return nextStyles;
+};


Seems like a thing we'd want unit tests for.

I see at least one possible issue: It won't handle anything short-hand that's still relevant for RTL, e.g.

margin: 0 10px 0 0;

Also, I'm confused about the reassignment of nextKey. It's being replaced into an array? But then the array is being used as the key of an object? An array is not a valid key of an object.

At which point: The RegExp#tests are redundant, because String#replace will do nothing if the pattern is not found.

Also: String#replace only replaces the first instance when provided a string, not all instances. You'd want your regular expression /left/gi for that (key.replace( /left/gi, 'right' ).
