Solid Router Navigation & Parameters

Navigation

A Component

Use <A> for navigation links (preferred over <a>):

import { A } from "@solidjs/router";

<A href="/">Home</A>
<A href="/about" activeClass="active" inactiveClass="inactive" end={true}>
  About
</A>
<A href="users">Users</A> {/* Relative path */}

Props:

• href: Path to navigate to
• activeClass: CSS class when active (default: "active")
• inactiveClass: CSS class when inactive (default: "inactive")
• end: Only active for exact match (default: false)

Active links match current route or descendant routes unless end={true}.

useNavigate

Programmatic navigation:

import { useNavigate } from "@solidjs/router";

function Login() {
  const navigate = useNavigate();
  
  const handleLogin = () => {
    navigate("/dashboard", { replace: true });
  };
  
  return <button onClick={handleLogin}>Login</button>;
}

Options:

• replace: true - Replace current history entry instead of pushing

redirect Function

Redirect from queries or actions (server-side):

import { query, redirect } from "@solidjs/router";

const checkAuth = query(async () => {
  if (!isAuthenticated()) {
    throw redirect("/login");
  }
  return getUserData();
}, "auth");

reload Function (Response Helper)

Use reload by returning or throwing it from queries or actions:

import { action, reload } from "@solidjs/router";

const savePreferences = action(async () => {
  // ...persist changes...
  return reload({ revalidate: ["userPreferences"] });
}, "savePreferences");

For client-side revalidation, use revalidate instead:

import { revalidate } from "@solidjs/router";

const refreshData = () => {
  revalidate(["userPreferences"]);
};

Route Parameters

Path Parameters

import { useParams } from "@solidjs/router";

// Route: /users/:id
function UserPage() {
  const params = useParams();
  return <div>User {params.id}</div>;
}

Search Parameters

import { useSearchParams } from "@solidjs/router";

function Search() {
  const [searchParams, setSearchParams] = useSearchParams();
  
  return (
    <div>
      <input 
        value={searchParams.q || ""} 
        onInput={(e) => setSearchParams({ q: e.target.value })}
      />
      <button onClick={() => setSearchParams({ q: "", page: "1" })}>
        Clear
      </button>
    </div>
  );
}

Utilities

useLocation

import { useLocation } from "@solidjs/router";

function Breadcrumb() {
  const location = useLocation();
  return <div>Current path: {location.pathname}</div>;
}

useMatch

import { useMatch } from "@solidjs/router";

function NavLink({ href, children }) {
  const match = useMatch(() => href);
  return (
    <A href={href} class={match() ? "active" : ""}>
      {children}
    </A>
  );
}

useIsRouting

import { useIsRouting } from "@solidjs/router";

function NavigationIndicator() {
  const isRouting = useIsRouting();
  return isRouting() ? <div>Navigating...</div> : null;
}

useBeforeLeave

import { useBeforeLeave } from "@solidjs/router";

function FormPage() {
  useBeforeLeave((e) => {
    if (hasUnsavedChanges()) {
      if (!confirm("Leave without saving?")) {
        e.preventDefault();
      }
    }
  });
}

Navigate Component

Immediate navigation when component renders. Useful for redirects:

import { Navigate } from "@solidjs/router";

// Simple redirect
<Route path="/redirect" component={() => <Navigate href="/target" />} />

// Dynamic redirect
function getPath({ navigate, location }) {
  return "/some-path";
}
<Route path="/redirect" component={() => <Navigate href={getPath} />} />

useCurrentMatches

Access all matched route information (useful for breadcrumbs):

import { useCurrentMatches } from "@solidjs/router";

const matches = useCurrentMatches();
const breadcrumbs = createMemo(() =>
  matches().map((m) => m.route.info.breadcrumb)
);

usePreloadRoute

Manually preload routes programmatically:

import { usePreloadRoute } from "@solidjs/router";

function Component() {
  const preload = usePreloadRoute();
  
  const handleClick = () => {
    preload("/users/settings", { preloadData: true });
  };
  
  return <button onClick={handleClick}>Preload Settings</button>;
}

Best Practices

1. Use <A> instead of <a> - Better router integration and features
2. Use relative paths in nested routes - More maintainable
3. Use end={true} for exact matches when needed
4. Use redirect for server-side navigation (authentication, etc.)
5. Handle search params reactively with useSearchParams
