router2

Client side routing for React applications. Inspired by Next.js.

It supports history management, dynamic routing, and link creation.

This npm package provides TypeScript files, and it is your responsibility to build and bundle it.

But Why?

This library is designed to be as simple as possible. It does not include any dependencies, making it easy to understand and modify. Additionally, this approach results in a smaller bundle size.

I need a bundled version.

You can still fork the library and modify the package.json. For configuration details, see rollup.config.js.

To build the package, run:

npm run build

Update your package.json like this:

{
  "main": "dist/cjs/index.js",
  "module": "dist/esm/index.js"
}

Overview

const { navigate, route } = useRouter();

navigate({ pathname: "/new-route" });

console.log(route);
// {
//   path: "/new-route",
//   pathname: "/new-route",
//   params: {},
// }

const { navigate, route } = useRouter();

navigate(
  { pathname: `/dynamic-route/${12}`, query: { key: "value" } },
  { replace: true },
);

console.log(route);
// {
//   path: "/dynamic-route/12",
//   pathname: "/dynamic-route/:id",
//   params: { ":id": "12", key: "value" },
// }

Getting Started

npm install router2

Components

BrowserRouter

The BrowserRouter component is the main component of this library. It uses React Context to provide routing functionality to its children.

<BrowserRouter routes={routes} />

Properties

• routes: This is a record object mapping route paths to React components. The "/404" path should be mapped to a component that will be displayed when no other route matches.

Example

Use routes object

const routes = {
  "/": () => <HomePage />,
  "/about": () => <AboutPage />,
  "/404": () => <NotFoundPage />,
};

<BrowserRouter routes={routes} />;

Use children

const routes = {
  "/": () => <HomePage />,
  "/about": () => <AboutPage />,
  "/404": () => <NotFoundPage />,
};

<BrowserRouter routes={routes}>
  {(Page) => (
    <InRouterContextProvider>
      <Page />
    </InRouterContextProvider>
  )}
</BrowserRouter>;

Link

The Link component creates an anchor element that interacts with the router.

<Link pathname="/some-route" query={{ key: "value" }} replace />

Properties

• pathname: The path of the route to navigate to when the link is clicked.
• query: An optional object representing the search parameters of the URL.
• replace: An optional boolean indicating whether the current history entry should be replaced instead of creating a new entry.
• All other properties of the anchor element are also supported.

API

useRouter

The useRouter hook returns the router object.

const router = useRouter();

Returns Router object.
