Hey there - I've reviewed your changes - here's some feedback:
- Some of the new ITheme JSDoc descriptions (e.g.,
colors.cerisevscolors.red/colors.lightRed) overlap in responsibility for error and warning states; consider tightening this language so it’s clear which color is preferred for which kinds of status UI. - In
tracing.css, forcing a solidbackground: var(--theme-bg-color, transparent)on.tracing-row__labelmay override any existing row striping or panel backgrounds; consider using a more transparent background or inheriting the parent background to avoid visual clashes.

## Overall Comments
- Some of the new ITheme JSDoc descriptions (e.g., `colors.cerise` vs `colors.red`/`colors.lightRed`) overlap in responsibility for error and warning states; consider tightening this language so it’s clear which color is preferred for which kinds of status UI.
- In `tracing.css`, forcing a solid `background: var(--theme-bg-color, transparent)` on `.tracing-row__label` may override any existing row striping or panel backgrounds; consider using a more transparent background or inheriting the parent background to avoid visual clashes.

**suggestion:** Clarify separation between `variable` and `property`/`definition` editor colors to avoid confusing theme authors.
Right now `variable` is described as `$variableName, field names, type names`, but `property` already covers field names and `definition` covers type/operation names. This overlap makes it unclear how each token should be used when building themes. Consider narrowing `variable` to `$variableName` (and possibly argument identifiers) so its scope is clearly distinct from `property` and `definition`, helping avoid inconsistent theming choices.
Suggested implementation:
```typescript
/**
* Color for variables and argument identifiers in queries.
* Used for:
* - Variable identifiers (e.g. $variableName)
* - Argument identifiers in field/operation signatures (e.g. id, limit, offset)
*
* Note:
* - Field names should be styled using the "property" color.
* - Type and operation names should be styled using the "definition" color.
*/
variable: string;
```
If the file also contains JSDoc comments for:
- `property` (e.g. "Color for object properties / field names" or similar), and
- `definition` (e.g. "Color for type/operation names"),
it would be good to:
1) Explicitly mention in the `property` comment that it is used for:
- Field names in GraphQL queries (e.g. user, posts, title)
- Object keys/properties in related UI representations, if applicable.
2) Explicitly mention in the `definition` comment that it is used for:
- Type names (e.g. User, Post)
- Operation names (e.g. getUser, listPosts)
- Fragment names, if your tokenizer exposes them as definitions.
Adjust the wording of those comments to match your existing style and terminology in `theme.ts`, but keep the separation:
- `variable` = `$variableName` + argument identifiers
- `property` = field/property names
- `definition` = type/operation (and optionally fragment) names

Code Review
This pull request significantly improves the theme customization documentation and fixes an important display issue with the Apollo Tracing plugin on light themes. The new JSDoc comments for the ITheme interface and the comprehensive rewrite of the theme-customization.md guide are excellent enhancements that will greatly benefit developers. The CSS changes correctly use theme variables to ensure compatibility. However, I've identified a critical issue with the newly added test file, where the tests are not validating the actual implementation, which could lead to a false sense of security. I've also pointed out a small omission in the new documentation to make it even more complete.

While adding tests is a great step, the current implementation of these tests is unfortunately ineffective. They are testing hardcoded strings and values within the test file itself, rather than verifying the actual styles from tracing.css or the behavior of the component.
For example:
- The tests define
cssContentas a local string variable and assert against it. This means the tests are completely decoupled from the actual CSS file and will pass even iftracing.cssis incorrect or empty. - The theme compatibility tests assert against hardcoded numbers (
bgLightness = 98) rather than calculating contrast from actual color values.
This approach provides a false sense of security.
Recommendation:
The tests should be rewritten to test the real implementation. Since you're using a jsdom environment, you can:
- Create a DOM element for the component.
- Load the actual
tracing.cssstylesheet into the test environment. - Use
window.getComputedStyle()to get the actual styles applied to the element. - Assert that the computed styles are correct (e.g.,
expect(computedStyle.color).toBe('var(--theme-font-color)')).
This will ensure your tests are validating the real behavior and will catch regressions in the future.

This visual mapping guide is very helpful! However, the 'Code Editor Syntax' table appears to be incomplete. It's missing the following properties which are defined in the ITheme interface and mentioned in the list starting on line 49:

packages/altair-core/src/theme/theme.ts (1)
55-265: Excellent documentation enhancement!The comprehensive JSDoc comments significantly improve the developer experience by clearly explaining:
- The purpose of each theme property
- Associated CSS variables for reference
- Specific UI locations where properties are applied
- Practical examples of usage
This documentation aligns perfectly with the PR objectives to improve theme customization understanding and addresses the issue where users had difficulty mapping ITheme properties to UI elements.
Based on learnings: Changes to packages/altair-core should be carefully reviewed as they impact multiple packages. Since these are documentation-only changes with no functional modifications, no additional testing is required.
packages/altair-docs/docs/features/theme-customization.md (1)
11-205: Outstanding documentation expansion!This comprehensive guide addresses the core issues raised in #2848 by providing:
- Clear property explanations - Each theme property now has a detailed description of its purpose and usage
- Visual mapping - Tables that map theme properties directly to UI elements, resolving the confusion about what controls what
- Accessibility guidance - Practical tips for users with reduced contrast sensitivity to create readable themes
- Real-world examples - High contrast dark theme and warm light theme patterns
- Editor color mapping - Clear explanation of what each editor color property controls in GraphQL syntax
The structured approach (Background, Text, Border, Brand colors) makes it easy to understand the theme system's organization. The CSS variable references alongside theme properties are particularly helpful for advanced customization.
Note: The static analysis hint about line 24 is a false positive - the sentence structure is correct.
plugins/apollo-tracing/src/components/Tracing/tracing.css (1)
51-79: Effective theme compatibility improvements!These CSS updates directly address the Apollo Tracing plugin's light theme rendering issues mentioned in #2848. The changes demonstrate good practices:
- Background contrast (lines 52-55) - Adding
theme-bg-colorbackground with padding and border-radius ensures text remains readable regardless of theme- Primary text color (line 62) - Using
theme-font-colorensures proper visibility in both light and dark themes- Reduced opacity (line 73) - The 0.9 opacity on the bar improves visibility across varied backgrounds
- Muted secondary text (line 79) - Using
theme-off-font-colorappropriately distinguishes duration textAll CSS variables include sensible fallback values, ensuring graceful degradation if variables aren't available.

1-210: Remove the suggestion to follow CSS testing restrictions; they don't apply to this plugin.The review incorrectly cites a coding guideline that applies only to Angular components in
packages/altair-app/. The rule "Do not test CSS styling or visual appearance" is explicitly documented under the "Angular Component Testing" section of app-testing.instructions.md and applies topackages/altair-app/src/app/modules/altair/components/**/*.spec.ts.This test file (
plugins/apollo-tracing/src/components/Tracing/tracing.spec.ts) is in a React plugin, not an Angular component in packages/altair-app. The guideline does not apply.That said, the substantive point about hardcoded CSS strings is worth considering: the tests verify hardcoded snippets rather than reading the actual
tracing.cssfile. However, this is a stylistic choice, not a requirement. The hardcoded strings in the tests match the actual CSS file accurately, so the tests do verify the expected CSS variable usage, just not by loading the file directly.Likely an incorrect or invalid review comment.

Remove unused variable lightThemeVars.
The variable is defined but never used in the test. If you intended to apply these CSS variables to test actual theme rendering, consider using a proper DOM testing approach with the variables actually applied.

deleting the unused lightThemeVars declaration to eliminate dead code, or
alternatively inject the variables into the test container (e.g., set style
properties on document.documentElement or the rendered element) and add
