How to call `useNavigate` outside of router

I am trying to create my own "page viewer" where I will be able to navigate between pages within the site; Currently I am using the Solid Router. But I want to be able to call the "window" to navigate from outside of the router. But I can't do that. I get the following error when trying to call useNavigate

Uncaught Error: <A> and 'use' router primitives can be only used inside a Route.

Uncaught Error: <A> and 'use' router primitives can be only used inside a Route.

I want to be able to do the following outside of the router: 1. Go back 2. Go forwards 3. Reload 4. Navigate 5. Clear navigation history So far I know for going forwards and backwards I can use history.back. But I cant refresh using location.reload because the window is a dialog so reloading is going to close the dialog. And the other options I don't really know what I can do. I tried to get the Navigate function by using the Navigate component and then taking the function from the parameter passed in the href e.g.

let navigate : Navigate | undefined;

const doStuff = ({n: Navigate}) => {
  navigate = n;
  return "/404"
}

return (
  <Router>
    <Route path={"/"} component={() => <Navigate href={doStuff}></Navigate>}></Route>
  </Router>

let navigate : Navigate | undefined;

const doStuff = ({n: Navigate}) => {
  navigate = n;
  return "/404"
}

return (
  <Router>
    <Route path={"/"} component={() => <Navigate href={doStuff}></Navigate>}></Route>
  </Router>

But that still causes errors and is ugly code. Any suggestions on what I can do? Thanks

Any specific reason why you want it outside the router? Most code i have seen has the router at the root.

eatingtheham•4mo ago

The router isnt at the root because my "site" is being run with tauri. So because it is a desktop app, I dont want to navigate the whole page. Just a section of it.

peerreynders•4mo ago

If this was my problem I'd look into crafting a Router root component that subscribes to a NavigationSubject that code outside of Router can dispatch navigation events to.

eatingtheham•4mo ago

How would I do the subscribing and observing?? Did some research and think I can use createContext but I am not too sure.

peerreynders•4mo ago

Something a lot more basic than that, your own vanilla JavaScript module. Here's an example that I used: https://github.com/peerreynders/nitro-sse-counter/blob/6f27d5d7bd9e119ca2fc1feb7cbe70f9308b84b6/src/client/lib/sinks.js When you create a Sinks<T> instance you can hand around it's send property (i.e. it's not method) to anyone who wants to dispatch T values, while you can pass around the add property, so that anyone can be notified of those values. So the root component would add itself listening for navigation events send (sent) from the outside. TC39: “There is an interest in an Observable but no one wants to deal with which one” So everybody keeps creating their own …

Hmm. This seems a bit complex for me right now... Thanks though. The whole process of observing is what I don't understand I think.

Brendonovich•4mo ago

may i ask why running in tauri impacts whether the router is at the root? making your whole app be controlled by the one router seems like it'd be easier

eatingtheham•4mo ago

Yeh. I could have it be multiple pages where I do navigation. But the design of my app is that there is a page-viewer which would load different pages. And it will have its own navigation. Then I would be able to close the viewer to access the homescreen. It is a bit complicated but that is what I thought would be cool to make i guess. I could just make my own router sort of. Just don't know how to "attach" methods to a component to call stuff for it. (Just a way I could be doing the routing)

Brendonovich•4mo ago

At a first glance I'd implement that with /home and /page/{page id} routes And then under /page/{page id} you can have all the page viewer's routes

eatingtheham•4mo ago

That is still involving multiple pages right?

eatingtheham•4mo ago

Here is my current layout

No description

Brendonovich•4mo ago

i assume each page has its own id, you'd just swap out the page id in the url and be viewing a different page Oh interesting so it's more of a modal view than a dedicated route?

eatingtheham•4mo ago

Yeh. But wouldn't that mean for each page I need to recreate the sidebar and stuff Yeh it is

Brendonovich•4mo ago

Nah the sidebar and things would live in a layout that exists at /page yeah this makes things a bit more interesting

eatingtheham•4mo ago

And /home i guess too.

Brendonovich•4mo ago

yeah in that case the layout can be at /

eatingtheham•4mo ago

ok... I still don't want to create multiple paths. Because at the home screen is a bunch of data that is taken from a config file. And I don't want to reload that information.

Brendonovich•4mo ago

if u fetch the data in a shared layout and the layout doesn't unmount then the information doesn't have to reload but the modal-ness of this makes it interesting i'm guessing the base view contains all the pages and then clicking on one opens the page viewer modal?

eatingtheham•4mo ago

Yeh. And the sidebar directs to pages as well. And... some pages navigate to other pages lol

Brendonovich•4mo ago

but the modal always appears on top of the existing route rather than completely replacing it yeah?

eatingtheham•4mo ago

yeah I am using a dialog to open and close it

Brendonovich•4mo ago

yeah that's a really intricate design, i think for that i'd store the dialog state in search params and roll my own mini router since it just doesn't fit with normal route nesting

eatingtheham•4mo ago

Yeh a "mini router" that is what I was thinking to make

Brendonovich•4mo ago

a json object in search params and some switch/match cases would do the trick

eatingtheham•4mo ago

why in the search params? I could store it as a global variable right...?

Brendonovich•4mo ago

yeah u could, but search params are also global variables... i just like keeping stuff in the url where possible web dev mentality

eatingtheham•4mo ago

Yeh that makes sense. And if it were a website that is how I would do it as well. But considering that this is a site with no url bar then it shouldnt be needed

Brendonovich•4mo ago

actually even for tauri apps counting on url state can be pretty useful for if u need to restore a user's session - just swap out the url once you've got state outside the url you need extra ways of persisting and loading it

eatingtheham•4mo ago

True. I don't want the state to be saved if the app just launches. But definatly when I restore the window after it came from the tray But im not sure if tauri saves the window state if it goes to the tray Electron does I think... so idk I might try creating a mini router component with data from a global signal Ok @Brendonovich, I have made it. Havent tested navigation yet. But have something... might not be the best way to do it though.

    }

        let x : {[p: string] : RouterComponent} = this.history.future.pop()!;
        this.history.past.push({[this.currentPath.get()]: currentElement()});

}

}

export {MiniRouter, CreateMiniRouterPath};

    this.router = <RouterViewer element={currentElement().element} props={currentElement().props}></RouterViewer>;

    this.navigate = (path: string, props?: {}) => {
      console.log("navigate")
      this.history.push(path);
      this.currentPathProps = props;
      this.history.future = [];
    }

    this.backwards = () => {
      if (this.history.past.length > 0) {
        let x : {[p: string] : RouterComponent} = this.history.past.pop()!;
        this.history.future.push({[this.currentPath.get()]: currentElement()});

        this.currentPathProps = x[0]?.props;
        this.currentPath.set(Object.keys(x)[0]);
      }
    }

    this.forwards = () => {

    }
  }
}

function CreateMiniRouterPath(path: string, element: ValidComponent, props?: {}) {
  return {[path]: {element, props}};
}

export {MiniRouter, CreateMiniRouterPath};

Then to use it I did the following

function PageViewer(props: PageViewerProps) {
  const router = new MiniRouter({
    paths: {
      ...CreateMiniRouterPath("/settings", SettingsPage),
      ...CreateMiniRouterPath("/install", InstallPage)
    }, invalid: InvalidPage, currentPath: "/settings"});


  return (
    <div>
      <router.router/>
    </div>
  )
}

function PageViewer(props: PageViewerProps) {
  const router = new MiniRouter({
    paths: {
      ...CreateMiniRouterPath("/settings", SettingsPage),
      ...CreateMiniRouterPath("/install", InstallPage)
    }, invalid: InvalidPage, currentPath: "/settings"});


  return (
    <div>
      <router.router/>
    </div>
  )
}

Sorry bit long. If you want it somewhere else I can do that Made a couple modifications. Now it navigates... Updated the code with the modifications

Thanks might take a look at it later. I got something to work for now though (code above ^^)
