Migrate from @policyengine/design-system to @policyengine/ui-kit by policyengine[bot] · Pull Request #1026 · PolicyEngine/policyengine-app-v2

policyengine · 2026-05-09T04:49:00Z

Summary

This PR migrates policyengine-app-v2 from @policyengine/design-system to @policyengine/ui-kit, following the pattern established in PolicyEngine/policybench#16.

Changes

Package Management

Root package.json: Replaced @policyengine/design-system with @policyengine/ui-kit v0.4.0
Workspace packages: Updated app/, website/, and calculator-app/ package.json files
Build scripts: Removed design-system:build scripts that are no longer needed

CSS Imports

website/src/app/globals.css: Changed from @import "@policyengine/design-system/tokens.css" to @import "@policyengine/ui-kit/theme.css"
The ui-kit theme.css provides all the same CSS variables and Tailwind tokens

TypeScript Token Imports

app/src/designTokens/: Converted from re-exports to hardcoded token values
- colors.ts: Now provides hardcoded color values matching ui-kit theme
- spacing.ts: Provides essential spacing tokens
- typography.ts: Provides font size tokens
website/src/: Updated 37+ files to import from local ../../../app/src/designTokens instead of @policyengine/design-system/tokens

Cleanup

Removed: packages/design-system/ directory entirely

Migration Strategy

Following the policybench pattern, this migration:

Replaces the npm dependency
Updates CSS imports to ui-kit's theme.css
Migrates runtime TS imports to use local hardcoded values
Removes the deprecated package

The local app/src/designTokens files now provide hardcoded values instead of re-exporting from the package, maintaining backward compatibility for components that use runtime token access while encouraging migration to CSS variables.

Testing

CI will verify:

All workspaces install correctly with ui-kit
TypeScript compilation succeeds
Linting passes
Builds complete successfully

Next Steps

This completes Block 3 (the host migration) from the issue. The design-system package can now be:

Deprecated on npm with a migration notice
Removed from publishing workflows

The remaining consumer repositories can be migrated separately following this same pattern.
