[Visual Refresh] Remove legacy Amsterdam theme #9090

mgadewoll · 2025-10-10T16:06:10Z

Summary

This PR removes all code related to the legacy "Amsterdam" theme as well as conditional theme specific code.

Additional changes

removes obsolete SCSS files
removes the theme switcher in the EUI docs and adds a "high contrast mode" toggle instead

default	enabled

Why are we making this change?

🧹 ✨ Maintainability: Removing the legacy "Amsterdam" theme to simplify the UI update workflow and reduce the "dead" code weight.

Screenshots #

Impact to users

🔴 This is a breaking change due to the removal of theme tokens and package files.
Consumers that rely on imports from /src/themes or SCSS files from src/global_styling/mixins as well as consumers using EuiThemeAmsterdam or euiTheme.flags need to update their code.

ℹ️ The required changes for Kibana have been prepared here.

QA

verify there is no "Amsterdam" related code in eui anymore
ensure eui, eui-theme-borealis and eui-theme-common packages build correctly
smoke test button and form components to verify there was no regression during the removal (running VRT is useful here)
verify the added high contrast mode switcher in the EUI docs works correctly

Consumer updates

ℹ️ No action required here. Adding the consumer updates for tracking purposes.

update Kibana to remove Amsterdam related code and verify CI doesn't fail (requires updates due to removed Amsterdam theme -> done here)
update Cloud-UI to remove Amsterdam related code and verify CI doesn't fail: https://github.com/elastic/cloud-ui/pull/565

General checklist

Browser QA
- Checked in both light and dark modes
- Checked in both MacOS and Windows high contrast modes
  - (emulate forced colors if you do not have access to a Windows machine.)
- Checked in mobile
- Checked in Chrome, Safari, Edge, and Firefox
- Checked for accessibility including keyboard-only and screenreader modes
Docs site QA
- Added documentation
- Props have proper autodocs (using @default if default values are missing) and playground toggles
- Checked Code Sandbox works for any docs examples
Code quality checklist
- Added or updated jest and cypress tests
- Updated visual regression tests
Release checklist
- A changelog entry exists and is marked appropriately.
- If applicable, added the breaking change issue label (and filled out the breaking change checklist)
Designer checklist
- If applicable, file an issue to update EUI's Figma library with any corresponding UI changes. (This is an internal repo, if you are external to Elastic, ask a maintainer to submit this request)

This PR contains breaking changes. The opener of this pull request is asked to perform the following due diligence steps below, to assist EUI in our next Kibana upgrade:

If this PR contains prop/API changes:
- Search through Kibana for <EuiComponent usages (example search)
- In the PR description or in a PR comment, include a count or list with the number of component usages in Kibana that will need to be updated (if that amount is "none", include that information as well)
If this PR contains CSS changes:
- Search through Kibana for the changed EUI selectors, e.g. .euiComponent (example search)
- In the PR description or in a PR comment, include a count or list with the number of custom CSS overrides in Kibana that will need to be updated (if that amount is "none", include that information as well)
🔍 Tip: When searching through Kibana, consider excluding **/target, **/*.snap, **/*.storyshot files to reduce noise and only look at source code usages
⚠️ For extremely risky changes, the EUI team should potentially consider the following precautions:
- Using a pre-release release candidate to test Kibana CI ahead of time
- Using kibana-a-la-carte for manual QA, and to give other Kibana teams a staging server to quickly test against

Log | Bot Usage

there are no JSON export files required to be copied anymore

- due to buttonVariant refactoring

- expected change (fix); the previous toggleTypeStyle wasn't applied correctly due to the nested object returned from euiFilterButtonDisplay

- due to formVariant refactoring

- removes global_styling SCSS files as they are located in eui-theme-common - removes component specific SCSS mixin files as those styles are not used within EUI anymore and the styles were not updated either

Will take a look at the Kibana PR and Cloud PR as a sanity check as well.

packages/eui/src/services/theme/provider.tsx

    if (!isParentTheme.current) {
      /* Enables recomputation of component colors when flags are overridden on the provider
      by adding the respective key to modifications to trigger a recomputation. */
+      // NOTE: Keeping this as placeholder for potential future usage during Borealis changes


Makes sense to me 👍🏻 good decision

Code review:

I shared some doubts I have but none of them are blocking. I also confirm there's nothing in the codebase that refers to "Amsterdam" theme (other than changelogs ofc):

Before approving, I'll also go through the touched components again to verify there's no regression from production (although functional and VRT tests passing should give enough confidence).

Components:

✅ EuiBetaBadge
✅ EuiNotificationBadge
✅ EuiButton
✅ EuiButtonEmpty
✅ EuiButtonGroup
✅ EuiButtonIcon
✅ EuiCollapsibleNavBeta
✅ EuiComboBox
✅ EuiDataGrid
✅ EuiSuperDatePicker
✅ EuiFilterGroup
✅ EuiFieldNumber
✅ EuiFieldText
✅ EuiFilePicker
✅ EuiFormControlLayout
✅ EuiFormErrorText
✅ EuiFormLabel
✅ EuiRange
✅ EuiHeader
✅ EuiKeyPadMenu
✅ EuiMarkdownEditor
✅ EuiPanel
✅ EuiResizableContainer
