Mvp/toolbar #6

Boxuan-Matty-Lin · 2025-11-21T05:14:52Z

This pull request introduces a major redesign of the app's tab navigation and theming, moving from the default Expo template to a custom "coffee shop" theme. It replaces the starter content with new screens and navigation structure, implements a custom tab bar with a central "Kopi" button, and updates the color palette and icon set to match the new branding. Additionally, it documents the tech stack and configuration in a new AGENTS.md file.

Navigation & Screens

Replaces the default Expo starter tabs and content with five new screens: Home, Favorites, Kopi (center tab), Orders, and Me, each with a simple placeholder layout and themed background/colors. (app/(tabs)/index.tsx, app/(tabs)/favorites.tsx, app/(tabs)/kopi.tsx, app/(tabs)/orders.tsx, app/(tabs)/me.tsx) [1] [2] [3] [4] [5]
Removes the old "Explore" and "Home" starter screens and their associated example/tutorial content. (app/(tabs)/explore.tsx, app/(tabs)/index.tsx) [1] [2]

Custom Tab Bar & Icons

Implements a custom tab bar in _layout.tsx with a prominent, elevated central "Kopi" button, custom icons, rounded corners, and themed colors. Uses a new KopiTabButton component for the center tab. (app/(tabs)/_layout.tsx)
Updates the icon mapping in icon-symbol.tsx to include new icons for the coffee theme (e.g., coffee cup, receipt, star, person).
Minor import order fix in icon-symbol.tsx.

Theming & Styling

Introduces a new color palette for light and dark modes, using coffee-inspired colors throughout the app. (constants/theme.ts, global.css) [1] [2]
Adds CSS variables for the new palette in global.css.

Documentation

Adds AGENTS.md to document the project's runtime, navigation, styling, animation, state management, tooling, and platform configuration.

app/(tabs)/index.tsx

-        </ThemedText>
-      </ThemedView>
-    </ParallaxScrollView>
+    <View className="flex-1 items-center justify-center bg-milk-coffee">


[nitpick] The order of flex utilities in className differs from other screens (using 'items-center justify-center' vs 'justify-center items-center'). For consistency with favorites.tsx, kopi.tsx, orders.tsx, and me.tsx, consider using 'justify-center items-center' order.

Suggested change

<View className="flex-1 items-center justify-center bg-milk-coffee">

+      <Text className="text-xl font-semibold text-dark-coffee">Home Screen</Text>


[nitpick] The font weight differs from other screens which use 'font-bold'. For consistency across all tab screens (favorites.tsx, kopi.tsx, orders.tsx, me.tsx), consider using 'font-bold' instead of 'font-semibold'.

Suggested change

<Text className="text-xl font-semibold text-dark-coffee">Home Screen</Text>

+    --color-light-coffee: #D7CCC8;
+    --color-medium-coffee: #8D6E63;
+    --color-grey: #BCAAA4;
+  }


CSS variables are only defined for light mode in :root. Dark mode will still use these same colors. Consider adding a dark mode selector (e.g., .dark) with appropriate color values to match the dark theme colors defined in constants/theme.ts, or document that NativeWind colors will only work in light mode.

+            shadowOpacity: isFocused ? 0.32 : 0.25,
+          },
+        ]}>
+        <IconSymbol size={KOPI_ICON_SIZE} name="cup.and.saucer.fill" color="#FFFFFF" />


[nitpick] Hardcoded white color ('#FFFFFF') is used instead of the theme colors. Consider using Colors.white or Colors[theme].background for consistency with the theming system, making it easier to adjust if the design changes.

Suggested change

<IconSymbol size={KOPI_ICON_SIZE} name="cup.and.saucer.fill" color="#FFFFFF" />

<IconSymbol size={KOPI_ICON_SIZE} name="cup.and.saucer.fill" color={Colors.white} />

app/(tabs)/_layout.tsx

+    borderTopLeftRadius: BAR_RADIUS,
+    borderTopRightRadius: BAR_RADIUS,
+    borderTopWidth: 1,
+    borderWidth: 1,


The borderWidth: 1 creates a border on all sides of the tab bar, but borderTopWidth: 1 is already set on line 167. This creates a double border on the top edge (2px total). Consider removing either borderWidth or borderTopWidth to avoid the redundant top border.

Suggested change

borderWidth: 1,
