Deep Linking Patterns for Mobile

URI Scheme Design

Design a consistent URI scheme before implementation:

myapp://                          # App root
myapp://home                      # Home screen
myapp://product/{id}              # Product detail
myapp://profile/{userId}          # User profile
myapp://settings/notifications    # Nested settings
myapp://search?q={query}          # Query parameters

Keep paths RESTful, lowercase, and predictable. Use path segments for hierarchy and query params for filters.

Custom schemes are neither unique nor secure — any app can register myapp://. Use them only as an internal/fallback channel; user-facing links should be verified HTTPS App Links (Android) / Universal Links (iOS). Note the parsing asymmetry: in myapp://product/123 the "product" part is the URI host, while in https://www.myapp.com/product/123 it is the first path segment — normalize before routing (see handlers below).
