Conversation
…aultLink#173) Replaces the hand-written theme toggle (useLocalStorage + classList) with next-themes for a robust, FOUC-free dark mode implementation. Changes: - Install next-themes dependency - Add ThemeProvider wrapping in Providers.tsx with attribute=class - Add suppressHydrationWarning to root <html> element - Replace Navbar useLocalStorage theme with useTheme() from next-themes - Remove manual dark class management useEffect - Add ThemeMigration component to migrate legacy JSON-stringified theme values - Config: defaultTheme=light, enableSystem, disableTransitionOnChange

|---|---|
Theme provider and hydration setup invofi/apps/frontend/package.json, invofi/apps/frontend/src/app/layout.tsx, invofi/apps/frontend/src/components/layout/Providers.tsx |
The frontend configures next-themes, migrates valid legacy local-storage values, supports system themes, and suppresses root hydration warnings. |
Navbar theme control invofi/apps/frontend/src/components/layout/Navbar.tsx |
The navbar uses useTheme for theme state and updates. Theme icons derive from the active dark-mode state. |
Estimated code review effort: 3 (Moderate) | ~20 minutes
Merge Risk: 🟡 Moderate · up to 61fa0
The change can leave users with a legacy theme preference in the wrong mode on first load and does not consistently honor or represent system theme selection. These bounded behavior issues should be addressed before merging.

Run the migration before next-themes initializes and synchronize provider state.
next-themes reads the quoted value during provider initialization and in its startup script. ThemeMigration runs only after commit, changes only localStorage, and does not update provider state. A legacy "dark" value can therefore leave the page light until reload.
Move the migration into the pre-initialization path, synchronize provider state, and add a first-load test for legacy "dark".

Complete system-theme support across the provider and Navbar.
enableSystem is configured, but the provider forces light mode for users without a saved preference and the Navbar does not represent or restore the "system" selection. next-themes separates the selected theme from the resolved system theme. (raw.githubusercontent.com)
