Description

Welcome to the new & improved number field (previously known as stepper)! 🥳🔢 This migration was quite complex, and added a LOT of new features to our humble number field.

New features include:

  • an error state with alert icon
  • optional help text
  • embedded field label & optional positions

Following React's lead, the markup of the number field has changed. You'll see that the .spectrum-Textfield div is where the S2 design language lives (instead of on the input element), while the actual input is unstyled and incorporated more subtly. Based on design's, React's and SWC's naming conventions, the display name for this component has also changed from stepper to numberField. This introduced breaking changes in all previous custom properties, where any --spectrum-stepper-* or --mod-stepper-* properties moved to --spectrum-numberfield-*or --mod-numberfield-*. This also applied to class names, where .spectrum-Stepper changed to .spectrum-NumberField. The hide-stepper class has also been updated to match our class naming conventions (.spectrum-NumberField--hiddenStepper).

Because of all the new features and to align more with design, SWC and React, below is a quick recap of the following tokens & classes that have been renamed in the CSS:

  • All .spectrum-Stepper* class names have been converted to .spectrum-NumberField*
  • The .hide-stepper class has been converted to .spectrum-NumberField--hiddenStepper
  • Custom properties have been renamed from --spectrum-stepper* to --spectrum-numberfield*
  • Modifiable custom properties have been renamed from --mod-stepper* to --mod-numberfield

Removed custom properties include:
--mod-stepper-animation-duration
--mod-stepper-button-border-width
--mod-stepper-button-width
--mod-stepper-button-width-quiet
--mod-stepper-buttons-background-color
--mod-stepper-buttons-border-color
--mod-stepper-buttons-border-color-focus
--mod-stepper-buttons-border-color-focus-hover
--mod-stepper-buttons-border-color-hover
--mod-stepper-buttons-border-color-keyboard-focus
--mod-stepper-buttons-border-style
--mod-stepper-buttons-border-width
--mod-stepper-focus-indicator-visibility
--mod-stepper-height (renamed to --mod-numberfield-block-size)
--mod-stepper-width (renamed to --mod-numberfield-inline-size)

New custom properties include:
--mod-numberfield-background-color
--mod-numberfield-background-color-disabled
--mod-numberfield-block-size (renamed from --mod-stepper-height)
--mod-numberfield-border-color-disabled
--mod-numberfield-border-color-invalid-default
--mod-numberfield-border-color-invalid-focus
--mod-numberfield-border-color-invalid-focus-hover
--mod-numberfield-border-color-invalid-hover
--mod-numberfield-border-color-invalid-keyboard-focus
--mod-numberfield-button-inline-offset
--mod-numberfield-font-family
--mod-numberfield-font-size
--mod-numberfield-font-style
--mod-numberfield-font-weight
--mod-numberfield-hidden-stepper-min-inline-size
--mod-numberfield-inline-size (renamed from --mod-stepper-width)
--mod-numberfield-label-to-field
--mod-numberfield-line-height
--mod-numberfield-min-inline-size
--mod-numberfield-spacing-block-end-edge-to-text
--mod-numberfield-spacing-block-start-edge-to-text
--mod-numberfield-spacing-field-to-helptext

This PR also incorporates the refactoring and test coverage that was introduced and tested in both #3558 and #3670 (both of which could be closed after this PR is merged 👍)

How and where has this been tested?

Please tag yourself on the tests you've marked complete to confirm the tests have been run by someone other than the author.

Validation steps

  • Pull down the branch to run this branch locally or visit the deploy preview.
  • Navigate to the number field docs page.
  • Verify that the new documentation is grammatically correct according to Spectrum content guidelines, and makes sense/is understandable.
  • Verify new links to other components' documentation work as expected.
  • Navigate to the default story page.
  • Using the Storybook controls, create different variations for the component including more complex combinations:
    • focus
    • focus + hover
    • disabled + invalid
    • invalid + keyboard focus
    • disabled + focus
    • side label only
    • side label + help text
    • invalid + help text
    • light vs dark mode
    • medium/desktop vs. large/mobile
    • and any other combinations you can create and test!
  • Following the token specs, verify number field's usage of the following tokens:
    • field-label-to-component (inspect .spectrum-NumberField-fieldLabel)
    • in-field-stepper-to-end-* sizing tokens to correspond to t-shirt sized number fields (inspect .spectrum-NumberField-buttons)
    • help-text-to-component (inspect .spectrum-NumberField-helpText in an invalid number field, for instance)
    • field-default-width-* sizing tokens to correspond to t-shirt sized number fields
    • number-field-minimum-width-multiplier (inspect .spectrum-NumberField--hiddenStepper/the hidden stepper number field)
    • number-field-with-stepper-minimum-width-* sizing tokens to correspond to t-shirt sized number fields (inspect .spectrum-NumberField)
    • component-height-* sizing tokens to correspond to t-shirt sized number fields (inspect .spectrum-NumberField-textfield)
    • corner-radius-medium-size-* sizing tokens to correspond to t-shirt sized number fields (inspect .spectrum-NumberField-textfield)
    • component-edge-to-text-* sizing tokens to correspond to t-shirt sized number fields (inspect .spectrum-NumberField-textfield)
    • component-top-to-text-* sizing tokens to correspond to t-shirt sized number fields (inspect .spectrum-NumberField-textfield)
    • component-bottom-to-text-* sizing tokens to correspond to t-shirt sized number fields (inspect the textfield mods in .spectrum-NumberField-input.spectrum-Textfield-input)
    • text-to-visual-* sizing tokens to correspond to t-shirt sized number fields (inspect the .spectrum-NumberField-input element of a default number field)
    • border-width-200 (inspect .spectrum-NumberField-textfield)
    • focus-indicator-thickness, focus-indicator-color, and focus-indicator-gap (inspect .spectrum-NumberField-inputs in a keyboard focused number field)
    • workflow-icon-size-* for each t-shirt size (for invalid number fields)
    • component-top-to-workflow-icon-* for each t-shirt size (check through the mods for textfield's icon spacing)
    • text-to-visual-* for each t-shirt size (inspect .spectrum-NumberField-input.spectrum-Textfield-input in the invalid number field)
    • number-field-visual-to-in-field-stepper-* for each t-shirt size (inspect .spectrum-NumberField-input.spectrum-Textfield-input in the invalid number field)
    • gray-25 (inspect .spectrum-NumberField-textfield and the mods for textfield's background color)
    • gray-300, gray-400, gray-800 and gray-900 for the various default variant border colors and states (inspect .spectrum-NumberField-textfield)
    • negative-border-color-default, negative-border-color-hover, negative-border-color-focus-hover, negative-border-color-focus and negative-border-color-key-focus for the various invalid variant border colors and states (inspect .spectrum-NumberField-textfield)
    • neutral-content-color-default, neutral-content-color-hover, neutral-content-color-focus-hover, neutral-content-color-focus and neutral-content-color-key-focus for the various id variant border colors and states (inspect .spectrum-NumberField-input and mods for the textfield text color)
    • negative-visual-color of the icon
    • disabled-content-color, disabled-border-color, disabled-background-color for the disabled state
    • default-font-family, regular-font-weight, default-font-style, line-height-100 as font styles
    • cjk-line-height-100 as font styles in the CJK contexts
    • font-size-* for each t-shirt size
  • Visit the Chromatic test preview.
  • Verify that the tests look as expected and have covered a large variety of test cases for the number field.

Additional Validation

  • Navigate to the forms docs page.
  • If you haven't already, pull down the branch to search the repo.
  • Search for Stepper in your IDE. No function calls, and no imports in references to Stepper should exist. As a caveat, there will still be references to stepper. The NPM package is still named "stepper," and all of the previous changelogs still use "stepper" as the component name, so not everything has been converted to "number field." We also have arguments in stories file that use the word "stepper," but all of the function calls to this component and any imports should be changed to NumberField.
  • Search for hide-stepper in your IDE. Nothing should be returned (except maybe some older JSON).
  • Search for --spectrum-Stepper and --mod-stepper in your IDE. Nothing should be returned except for changelogs.
  • Feel free to view the Chromatic test preview in WHCM to verify the component aligns with textfield (maybe it's not identical, but it should align closely).

Regression testing

Validate:

  1. The documentation pages for at least two other components are still loading, including:
  • The pages render correctly, are accessible, and are responsive.
  1. If components have been modified, VRTs have been run on this branch:
  • VRTs have been run and looked at.
  • Any VRT changes have been accepted (by reviewer and/or PR author), or there are no changes.

I moved the hidden stepper to its own testData object instead of a "state," since the validation icon placement is different between the default/with buttons and the hidden stepper buttons.

For the truncation test cases, do you think its necessary to demonstrate the field label and/or the help text wrapping? Those situations are already captured in their respective Chromatic tests, but is it something we also need to capture here in the number field tests?

Any reservations on pulling the isInvalid arg from Textfield here, instead of from the shared types? I particularly liked the description of the invalid state that textfield has, which is why I opted for this.

That seems fine, since textfield will pull it from the shared types, no need to add a duplicate description.

I hardcoded this displayLabel: false (as opposed to displayLabel getting passed into Textfield) so that we wouldn't get duplicate field labels.

Does that make sense, or should I refactor? I'm pretty sure I could just use the embedded field label (and maybe even the help text) that's already within the textfield component, with some additional CSS edits.

Ohhh, this is a little weird... my initial instinct is that we shouldn't be dealing with field labels in each. But using textfield's field label also feels weird because it's a bit different (I think) from what SWC does, and it'd be better to be more aligned rather than less aligned.

It kind of feels like it's Textfield's fault that you have to do this. What would be pros/cons of separating the Textfield input from the Textfield with the field label and help text in the template? Like, that Textfield input could be a separate export that we could use in number field? I feel like Picker is also composed in this way? What do you think? If we did something like that, it doesn't have to be done here, I think this works fine for now, because if we change textfield's template, we'll start potentially affecting other components that use textfield too.

Also, why is field label a boolean situation with label text and help text is just a string (in textfield)? That feels inconsistent.

I have 2 background-color-disabled props currently. The first matched the token specs, where disabled-background-color is used. The second follows what's actually defined in Figma, which is gray-25.

gray-25 looks like all of the Figma designs, where using disabled-background-color (even though that's what's in the token specs) looks more like S1. I think @rise-erpelding had the same issue in the textfield S2 migration.

I just added a click to the inline buttons while I was playing around with this. You can now decrement or increment. I was thinking not add some interactivity for fun?

  onAdd: function () {
		const newValue = String(parseFloat(value) + 0.5);
		updateArgs?.({ value: newValue });
	},
	onMinus: function () {
		const newValue = String(parseFloat(value) - 0.5);

Oh! I didn't realize we already had these args baked into the the inline buttons so we could pass down increment/decrement functions. We often try to avoid JavaScript implementation in the template because it's unnecessary overhead and we don't ship it anywhere, but this is a really small enhancement that I think would be nice.

Awesome work on this @marissahuysentruyt ! Only thing I can think of right now is adding the Storybook downstate interaction on the infield button and click functions in the isInline clicks to add and subtract.

Oh! I really wanted to include an internationalization test to the grid (specifically with all of our line-height bug fixes for Thai in textfield/picker/action button), but I couldn't get the Thai numerals to display. Maybe I don't actually have the right characters?

I think it might be because it's input type number, which... a quick Google search didn't pull up the answer but the AI said it would only accept Arabic numerals (as in the number characters that we're familiar with) and not Thai characters. I think it's fine to leave it out, but we can still hold on to it as a question or possible follow-up item?

This is looking great considering it's a really huge migration (from what it looked like before)! Left a few small comments, and I'm wondering particularly about the textfield passthroughs on the CSS.

That seems fine, since textfield will pull it from the shared types, no need to add a duplicate description.

* Steppers come in four different sizes: small, medium, large, and extra-large. The medium size is the default and most frequently used option. Use the other sizes sparingly; they should be used to create a hierarchy of importance within the page.
* Number fields come in four different sizes: small, medium, large, and extra-large. The medium size is the default and most frequently used option. Use the other sizes sparingly; they should be used to create a hierarchy of importance within the page.
*
* Number fields have a [field label](/docs/components-field-label--docs) that is positioned above the field by default, with a secondary option to be positioned on the side of the field. The [inline infield buttons](/docs/components-in-field-button--docs#inline) are usually visible, but can be hidden. When the label is to long for the available space, it will wrap to the next line. If the value within the number field input overflows, it will truncate with an ellipsis.

I think it might be because it's input type number, which... a quick Google search didn't pull up the answer but the AI said it would only accept Arabic numerals (as in the number characters that we're familiar with) and not Thai characters. I think it's fine to leave it out, but we can still hold on to it as a question or possible follow-up item?

Also, why is field label a boolean situation with label text and help text is just a string (in textfield)? That feels inconsistent.

I noticed that the inline-size on .spectrum-Textfield that includes this --mod-textfield-width is crossed out, maybe we don't need to set this mod? Or maybe we set it to 100% so we don't need to set inline-size on .spectrum-NumberField-textfield?

I'm wondering if the spacing needs a few adjustments, I noticed that when I type in many numbers, the padding creates a lot of white space between the last number and the buttons, definitely more than the spec:

Inspecting it seems like that text-to-stepper token is being overridden so it never gets used:

/* @passthrough start -- MODS for sub components */
/* nested textfield */
--mod-textfield-corner-radius: var(--mod-numberfield-border-radius, var(--spectrum-numberfield-border-radius));
--mod-textfield-border-width: var(--mod-numberfield-border-width, var(--spectrum-numberfield-border-width));

I have another comment below because I saw this with inline-size first, but it looks like we're doing passthroughs to textfield that are passed through but being overridden for border width and some other properties:

Looks like the border, for instance, is also being set on .spectrum-NumberField-textfield:

Oh! I didn't realize we already had these args baked into the the inline buttons so we could pass down increment/decrement functions. We often try to avoid JavaScript implementation in the template because it's unnecessary overhead and we don't ship it anywhere, but this is a really small enhancement that I think would be nice.
