Information

This RFC proposes adding support for Custom URL Matchers within the existing filesystem-based routing of Analog. This feature would allow developers to define custom logic for URL pattern matching directly within .page.ts files, enabling more flexible and complex routing patterns.

Proposed Implementation:

1. Naming Pattern for Custom Matchers:

• Introduce a naming convention or symbol (e.g., $) in .page.ts filenames to signify that the file contains a custom URL matcher.
• For example, a file named [$example].page.ts would indicate that this route uses a custom matcher instead of relying on standard static or dynamic routing.

2. Matcher Defined Inside .page.ts:

• Developers would define a custom matcher function, similar to Angular’s UrlMatcher. This function would return a UrlMatchResult if the URL matches the defined logic.

  Example:

  export const urlMatcher = (segments: UrlSegment[], group: UrlSegmentGroup, route: Route): UrlMatchResult | null => {
     ...
  };
