[✨] Add `trailingIndex` to QwikCity that enables SPA builds to function in Capacitor, Cordova, and other hybrid native app environments

[n8sabes]

Is your feature request related to a problem?

To support SPA builds for Capacitor, Cordova and other static hybrid host environments, it is necessary to include /index.html to the path. Currently this is not possible without custom link logic sprinkled throughout the entire project.

Describe the solution you'd like

Enhance QwikCity to include trailingIndex.

export interface QwikCityPlan {
  readonly routes: RouteData[];
  readonly serverPlugins?: RouteModule[];
  readonly basePathname?: string;
  readonly menus?: MenuData[];
  readonly trailingSlash?: boolean;
  readonly trailingIndex?: boolean;    // <-------
  readonly cacheModules?: boolean;
}

Describe alternatives you've considered

Custom <SmartLink /> components. This works but adds a layer of complexity to every project.

This makes sense but I think it should be a third state for trailingSlash, so true, false, or "index". If .html$ is missing from the path, /index.html should always be added.

Qwik-city doesn't have any other .html files right? So if you do /products/[id] it should result in /products/chair/index.html, correct?

[n8sabes]

@wmertens, your example path is correct. I agree the third state would be a better solution, but just don't like the variable name but can live with it.

I am working on a Capacitor integration in Qwik, this enhancement would be good.

We moved this issue to qwik-evolution repo to create a RFC discussion for this.
Here is our Qwik RFC process thanks.
