A simple, lightweight react router using hooks, written in TypeScript.

Why use this router?

  • Very lightweight (see the badges above for the latest size).
  • Flexible and dead simple to use.
  • Uses the browsers history API.
  • Does not force a matching algorithm on you, but comes with a simple one built-in.
  • Written with hooks in TypeScript
  • Only has one peer dependency: React 16.12.0 or higher.
  • Liberal license: zlib/libpng

Installation via NPM

npm i react-router-ts

This library is shipped as es2015 modules. To use them in browsers, you'll have to transpile them using webpack or similar, which you probably already do.



You'll need to add a Router component in your app (just one). Any other components and hooks from this library need to be children of this Router (doesn't matter how deeply nested).

import { Router } from "react-router-ts";
export const App = () => (


Showing a component if the location matches a certain path is done with a Route component. It takes a path prop and either a component prop or children.

export const Component = () => (
        <Route path="/news" component={News} />
        <Route path="/fakenews">Drumpf</Route>

Beware: If multiple routes have a matching path, all will be shown. Use a Switch if that's not desired.

As you can see, it's possible to specify a component to render or normal children.

You can even use a callback instead of children like this:

export const Component = () => (
    <Route path="/foo">{(params: { id: string }) => <div>Bar {}</div>}</Route>;

See further below for the the possibility of using parameters.


If you only want the first Route that has a matching path to be shown, you can use a Switch:

export const Component = () => (
        <Route path="/news" component={News} />
        <Route path="/fakenews" component={FakeNews} />
        <Route path="*" /* use "(.*)" if you use path-to-regexp */ component={Otherwise} />

Note: The path pattern for the "Otherwise" Route differs depending on your route matching algorithm. With the built-in simpleRouteMatcherFactory you would use "*", while you would use "(.*)" or "/:fallback" for path-to-regexp.

Get parameters without being in a Route Component

You can get a memoized parameters object for the given path like this:

export const Component = () => {
    const params = useParams<{ id: string }>("/news/:id");

Custom Route Matching

This library doesn't force a route matching algorithm on you, but it comes with a lightweight one built-in.

The default route matching algorithm only allows exact matches and a match everything ("*").

If you need something more sophisticated, you'll have to supply a factory. Here is a simple example using the popular path-to-regexp library:

import { pathToRegexp, Key } from "path-to-regexp";
import { Router, RouteParams } from "react-router-ts";
function routeMatcherFactory(pattern: string) {
    const keys: Key[] = [];
    const regex = pathToRegexp(pattern, keys);
    return (path: string) => {
        const out = regex.exec(path);
        if (!out) return null;
        return keys.reduce((params, key, i) => {
            params[] = out[i + 1];
            return params;
        }, {} as RouteParams);
export const App = () => (
    <Router routeMatcherFactory={routeMatcherFactory}>

Using pathToRegexp allows to extract named parameters from a pattern like "/users/:name". I.e. if the path is "/users/Zaphod", then the param with the key "name" would have the value "Zaphod".

Adding parameters

When you use a custom matching algorithm like the one above, you can extract values from the path. Let's say you have this route:

export const Component = () => (
    <Route path="/news/:id" component={News} />

You defined a parameter :id in your path. Now you want to access it in your News component:

export const News = (props: RouteComponentProps<{ id: string }>) => (
    <div>News ID: {}</div>

Fresh Rendering

Let's say you have this route:

export const Component = () => <Route path="/news/:id" component={News} />;

Moving from /news/1 to /news/2 will only update the components properties. State will be preserved. If you want to force the component to be created from scratch in this situation, you can do so by setting the property addKey (boolean). This will add the key property to the component with a value of the current path.

Storing the route in the hash instead

In some situations, it's easier to store the route in the hash part of the URL, as it avoids the server having to be aware of the single page application behavior. You can enable the "hash" mode on the Router component:

import { Router } from "react-router-ts";
export const App = () => (
    <Router mode="hash">

This will result in a url like instead of

This approach will still use the history API internally!

Using a basename

If your app is not located at the root directory of a server, but instead in a sub-directory, you'll want to specify that sub-directory. You can do that on the Router component.

Basename will be prefixed on Link components.

import { Router } from "react-router-ts";
export const App = () => (
    <Router basename="/my-app">

If you have a <base> tag in your HTML, this can be easily detected using the getBasename() helper. That way you don't have to hard-code it:

import { Router, getBasename } from "react-router-ts";
export const App = () => (
    <Router basename={getBasename()} routeMatcherFactory={routeMatcherFactory}>


The Link component can be used to change the url and still act as a normal <a> tag, so you can open the link in a new tab.

export const Component = () => (<Link href="/hello">Test</Link>);

Any extra props you pass in will be forwarded to the <a> element. If you specify an onClick property and it calls preventDefault(), then the history change will not happen, as would be the case with any normal link.

LinkButton, etc.

If you want to create a LinkButton or similar, you can do that easily. This is the implementation of Link:

export function Link(props: React.PropsWithChildren<LinkProps>) {
    const routeLink = useRouteLink(props.href, props.onClick);
    return <a {...props} href={routeLink.href} onClick={routeLink.onClick} />;

Creating a LinkButton is as simple as this:

import { useRouteLink } from "react-router-ts";
export function LinkButton(props: React.PropsWithChildren<LinkButtonProps>) {
    const routeLink = useRouteLink(props.href, props.onClick);
    return <button {...props} onClick={routeLink.onClick} />;


Router internally adds a RouterContext to your application, which you can access using the useRouter() hook:

import { useRouter } from "react-router-ts";
export function Component() {
    // router is of type RouterContextValue (see below)
    const router = useRouter();

RouterContextValue is defined as:

export interface RouterContextValue {
    basename: string;
    path: string;
    history: RouterHistory;
    matchRoute: CachedRouteMatcher;
    urlTo: (path: string) => string;
// with:
export interface RouterHistory {
    push: (path: string) => void;
    replace: (path: string) => void;
    stop: () => void; // for internal use, do not call.
    urlTo: (path: string) => string;
// and:
export type CachedRouteMatcher = (pattern: string, path: string) => (RouteParams | null);

urlTo() can be used to create a new url, which respects basename and mode. It's the same for both RouterContextValue and RouterHistory.
