Move ThemeProvider implementation to styled-react #6817

siddharthkp · 2025-09-09T20:07:39Z

Towards https://github.com/github/primer/issues/5427
We already exported ThemeProvider in Export theming utilities from styled-react #6703
This PR copies over the full implementation so that we can make changes to the ThemeProvider from @primer/react
integration-tests: skipped manually because I'm only adding a couple exports for hooks in primer/react, there are no modifications
includes changes from styled-react: Fix browser tests not running #6822

Pull Request Overview

This PR moves the ThemeProvider implementation from @primer/react to @primer/styled-react as part of a migration strategy.

Key changes:

Added complete ThemeProvider implementation with theme utilities and color scheme support
Exported new hooks (useId, useSyncedState) from @primer/react to support the ThemeProvider
Updated test configuration to support both node and browser testing environments

packages/styled-react/src/theming/utils/theme.ts

+// Temporarily disabling since this is originally a JavaScript that needed to be
+// migrated to TypeScript for exports to work as correctly in Vite.
+// eslint-disable-next-line @typescript-eslint/ban-ts-comment
+// @ts-nocheck


The @ts-nocheck directive disables all TypeScript checking for this file, which defeats the purpose of migrating to TypeScript. Consider removing this directive and properly typing the functions instead of bypassing type safety entirely.

packages/styled-react/src/theming/ThemeProvider.tsx

+const defaultNightScheme = 'dark'
+
+// eslint-disable-next-line @typescript-eslint/no-explicit-any
+export type Theme = {[key: string]: any}


Using any type defeats TypeScript's type safety. Consider defining a more specific interface for the Theme type or using unknown if the structure is truly dynamic.

Suggested change

export type Theme = {[key: string]: any}

export type Theme = {[key: string]: unknown}
