How to upgrade React Router v5 to v6

Note: This document is still a work in progress! The migration process from React Router v5 to v6 isn’t yet as smooth as we would like it to be. We are planning on backporting several of v6’s new APIs to v5 to make it smoother, and this guide will keep improving as we continue to gather feedback.

React Router version 6 introduces several powerful new features, as well as improved compatibility with the latest versions of React. It also introduces a few breaking changes from version 5. This document is a comprehensive guide on how to upgrade your v4/5 app to v6 while hopefully being able to ship as often as possible as you go.

If you are just getting started with React Router or you’d like to try out v6 in a new app, please see the Getting Started guide.

The examples in this guide will show code samples of how you might have built something in a v5 app, followed by how you would accomplish the same thing in v6. There will also be an explanation of why we made this change and how it’s going to improve both your code and the overall user experience of people who are using your app.

In general, the process looks like this:

  • Upgrade to React v16.8 or greater
  • Upgrade to React Router v5.1
    • Use <Route children> everywhere
    • Use hooks instead of withRouter and “floating” <Route>s (that aren’t part of a <Switch>)
  • Upgrade to React Router v6
    • Upgrade all <Switch> elements to <Routes>
      • Update <Link to> values
      • Update <Route path> patterns
      • Remove <Route exact> and <Route strict> props
      • Move <Route sensitive> to containing <Routes caseSensitive>
      • Consolidate your <Route>s into a nested config (optional)
    • Use navigate instead of history
      • Use useNavigate hook instead of useHistory
      • Use <Navigate> instead of <Redirect> (outside of route configs)
        • No need to change <Redirect> directly inside <Routes>
    • Use useRoutes instead of react-router-config
    • Rename <Link component> to <Link as>
    • Get StaticRouter from react-router-dom/server

Upgrade to React v16.8

React Router v6 makes heavy use of React hooks, so you’ll need to be on React 16.8 or greater before attempting the upgrade to React Router v6. The good news is that React Router v5 is compatible with React >= 15, so if you’re on v5 (or v4) you should be able to upgrade React without touching any of your router code.

Once you’ve upgraded to React 16.8, you should deploy your app. Then you can come back later and pick up where you left off.

Upgrade to React Router v5.1

It will be easier to make the switch to React Router v6 if you upgrade to v5.1 first. In v5.1, we released an enhancement to the handling of <Route children> elements that will help smooth the transition to v6. Instead of using <Route component> and <Route render> props, just use regular element <Route children> everywhere and use hooks to access the router’s internal state.

// v4 and v5 before 5.1
function User({ id }) {
  // ...
}

<Switch>
  <Route exact path="/" component={Home} />
  <Route path="/about" component={About} />
  <Route
    path="/users/:id"
    render={
      ({ match }) => <User id={match.params.id} />
    }
  />
</Switch>

// v5.1 preferred style
function User() {
  let { id } = useParams();
  // ...
}

<Switch>
  <Route exact path="/"><Home /></Route>
  <Route path="/about"><About /></Route>
  {/* Can also use a named `children` prop */}
  <Route path="/users/:id" children={<User />} />
</Switch>

In general, React Router v5.1 (and v6) favors elements over components (or “element types”). There are a few reasons for this, but we’ll discuss more further down when we discuss v6’s <Route> API.

When you use regular React elements you get to pass the props explicitly. This helps with code readability and maintenance over time. If you were using <Route render> to get a hold of the params, you can just useParams inside your route component instead.

Along with the upgrade to v5.1, you should replace any usage of withRouter with hooks. You should also get rid of any “floating” <Route> elements that are not inside a <Switch>.

In summary, to upgrade from v4/5 to v5.1, you should:

  • Use <Route children> instead of <Route render> and/or <Route component> props
  • Replace all uses of withRouter with hooks
  • Replace any <Route>s that are not inside a <Switch> with useRouteMatch, or wrap them in a <Switch>

Again, once your app is upgraded to v5.1 you should test and deploy it, and pick this guide back up when you’re ready to continue.

Upgrade to React Router v6

Heads up: This is the biggest step in the migration and will probably take the most time and effort.

For this step, you’ll need to install React Router v6. If you’re managing dependencies via npm:

$ npm install react-router@6 react-router-dom@6
# or, for a React Native app
$ npm install react-router@6 react-router-native@6

Upgrade all <Switch> elements to <Routes>

React Router v6 introduces a Routes component that is kind of like Switch, but a lot more powerful. The main advantages of Routes over Switch are:

  • All <Route>s and <Link>s inside a <Routes> are relative. This leads to leaner and more predictable code in <Route path> and <Link to>
  • Routes are chosen based on the best match instead of being traversed in order. This avoids bugs due to unreachable routes because they were defined later in your <Switch>
  • Routes may be nested in one place instead of being spread out in different components. In small to medium sized apps, this lets you easily see all your routes at once. In large apps, you can still nest routes in bundles that you load dynamically via React.lazy

In order to use v6, you’ll need to convert all your <Switch> elements to <Routes>. If you already made the upgrade to v5.1, you’re halfway there.

First, let’s talk about relative routes and links in v6.

Relative Routes and Links

In v5, you had to be very explicit about how you wanted to nest your routes and links. In both cases, if you wanted nested routes and links you had to build the <Route path> and <Link to> props from the parent route’s match.url and match.path properties. Additionally, if you wanted to nest routes, you had to put them in the child route’s component.

// This is a React Router v5 app
import { BrowserRouter, Switch, Route, Link, useRouteMatch } from 'react-router-dom';

function App() {
  return (
    <BrowserRouter>
      <Switch>
        <Route exact path="/"><Home /></Route>
        <Route path="/users"><Users /></Route>
      </Switch>
    </BrowserRouter>
  );
}

function Users() {
  // In v5, nested routes are rendered by the child component, so
  // you have <Switch> elements all over your app for nested UI.
  // You build nested routes and links using match.url and match.path.
  let match = useRouteMatch();

  return (
    <div>
      <nav>
        <Link to={`${match.url}/me`}>My Profile</Link>
      </nav>

      <Switch>
        <Route path={`${match.path}/me`}><OwnUserProfile /></Route>
        <Route path={`${match.path}/:id`}><UserProfile /></Route>
      </Switch>
    </div>
  );
}

This is the same app in v6:

// This is a React Router v6 app
import { BrowserRouter, Routes, Route, Link } from 'react-router-dom';

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="users/*" element={<Users />} />
      </Routes>
    </BrowserRouter>
  );
}

function Users() {
  return (
    <div>
      <nav>
        <Link to="me">My Profile</Link>
      </nav>

      <Routes>
        <Route path=":id" element={<UserProfile />} />
        <Route path="me" element={<OwnUserProfile />} />
      </Routes>
    </div>
  );
}

A few important things to notice about v6 in this example:

  • <Route path> and <Link to> are relative. This means that they automatically build on the parent route’s path and URL so you don’t have to manually interpolate match.url or match.path
  • <Route exact> is gone. Instead, routes with descendant routes (defined in other components) use a trailing * in their path to indicate they match deeply
  • You may put your routes in whatever order you wish and the router will automatically detect the best route for the current URL. This prevents bugs due to manually putting routes in the wrong order in a <Switch>

You may have also noticed that all <Route children> from the v5 app changed to <Route element> in v6. Assuming you followed the upgrade steps to v5.1, this should be as simple as moving your route element from the child position to a named element prop (TODO: can we provide a codemod here?).

Advantages of <Route element>

In the section about upgrading to v5.1, I promised you we’d discuss the advantages of using regular elements instead of components (or element types) for rendering. Let’s take a quick break from upgrading and talk about that now.

For starters, we see React itself taking the lead here with the <Suspense fallback={<Spinner />}> API. The fallback prop takes a React element, not a component. This lets you easily pass whatever props you want to your <Spinner> from the component that renders it.

Using elements instead of components means we don’t have to provide a passProps-style API so you can get the props you need to your elements. For example, in a component-based API there is no good way to pass props to the <Profile> element that is rendered when <Route path=":userId" component={Profile} /> matches. Most React libraries who take this approach end up with either an API like <Route component={Profile} passProps={{ animate: true }} /> or use a render prop or higher-order component.

Also, I’m not sure if you noticed this but in v4 and v5, Route’s rendering API became rather large. It went something like this:

// Ah, this is nice and simple!
<Route path=":userId" component={Profile} />

// But wait, how do I pass custom props to the <Profile> element??
// Hmm, maybe we can use a render prop in those situations?
<Route
  path=":userId"
  render={routeProps => (
    <Profile routeProps={routeProps} animate={true} />
  )}
/>

// Ok, now we have two ways to render something with a route. :/

// But wait, what if we want to render something when a route
// *doesn't* match the URL, like a Not Found page? Maybe we
// can use another render prop with slightly different semantics?
<Route
  path=":userId"
  children={({ match }) => (
    match ? (
      <Profile match={match} animate={true} />
    ) : (
      <NotFound />
    )
  )}
/>

// What if I want to get access to the route match, or I need
// to redirect deeper in the tree?
function DeepComponent(routeStuff) {
  // got routeStuff, phew!
}
export default withRouter(DeepComponent);

// Well hey, now at least we've covered all our use cases!
// ... *facepalm*

At least part of the reason for this API sprawl was that React did not provide any way for us to get the information from the <Route> to your route element, so we had to invent clever ways to get both the route data and your own custom props through to your elements: component, render props, passProps higher-order-components … until hooks came along!

Now, the conversation above goes like this:

// Ah, nice and simple API. And it's just like the <Suspense> API!
// Nothing more to learn here.
<Route path=":userId" element={<Profile />} />

// But wait, how do I pass custom props to the <Profile>
// element? Oh ya, it's just an element. Easy.
<Route path=":userId" element={<Profile animate={true} />} />

// Ok, but how do I access the router's data, like the URL params
// or the current location?
function Profile({ animate }) {
  let params = useParams();
  let location = useLocation();
}

// But what about components deep in the tree?
function DeepComponent() {
  // oh right, same as anywhere else
  let navigate = useNavigate();
}

// Aaaaaaaaand we're done here.

Another important reason for using the element prop in v6 is that <Route children> is reserved for nesting routes. This is one of people’s favorite features from v3 and @reach/router, and we’re bringing it back in v6. Taking the code in the previous example one step further, we can hoist all <Route> elements into a single route config:

// This is a React Router v6 app
import { BrowserRouter, Routes, Route, Link, Outlet } from 'react-router-dom';

function App() {
  return (
    <BrowserRouter>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="users" element={<Users />}>
          <Route path="me" element={<OwnUserProfile />} />
          <Route path=":id" element={<UserProfile />} />
        </Route>
      </Routes>
    </BrowserRouter>
  );
}

function Users() {
  return (
    <div>
      <nav>
        <Link to="me">My Profile</Link>
      </nav>

      <Outlet />
    </div>
  )
}

This step is optional of course, but it’s really nice for small to medium sized apps that don’t have thousands of routes.

Notice how <Route> elements nest naturally inside a <Routes> element. Nested routes build their path by adding to the parent route’s path. We didn’t need a trailing * on <Route path="users"> this time because when the routes are defined in one spot the router is able to see all your nested routes.

You’ll only need the trailing * when there is another <Routes> somewhere in that route’s descendant tree. In that case, the descendant <Routes> will match on the portion of the pathname that remains (see the previous example for what this looks like in practice).

When using a nested config, routes with children should render an <Outlet> in order to render their child routes. This makes it easy to render layouts with nested UI.

Note on <Route path> patterns

React Router v6 uses a simplified path format. <Route path> in v6 supports only 2 kinds of placeholders: dynamic :id-style params and * wildcards. A * wildcard may be used only at the end of a path, not in the middle.

All of the following are valid route paths in v6:

/groups
/groups/admin
/users/:id
/users/:id/messages
/files/*
/files/:id/*
/files-*

The following RegExp-style route paths are not valid in v6:

/users/:id?
/tweets/:id(\d+)
/files/*/cat.jpg

We added the dependency on path-to-regexp in v4 to enable more advanced pattern matching. In v6 we are using a simpler syntax that allows us to predictably parse the path for ranking purposes. It also means we can stop depending on path-to-regexp, which is nice for bundle size.

If you were using any of path-to-regexp’s more advanced syntax, you’ll have to remove it and simplify your route paths. If you were using the RegExp syntax to do URL param validation (e.g. to ensure an id is all numeric characters) please know that we plan to add some more advanced param validation in v6 at some point. For now, you’ll need to move that logic to the component the route renders, and let it branch it’s rendered tree after you parse the params.

If you were using <Route sensitive> you should move it to its containing <Routes caseSensitive> prop. Either all routes in a <Routes> element are case-sensitive or they are not.

One other thing to notice is that all path matching in v6 ignores the trailing slash on the URL. In fact, <Route strict> has been removed and has no effect in v6. This does not mean that you can’t use trailing slashes if you need to. Your app can decide to use trailing slashes or not, you just can’t render two different UIs client-side at <Route path="edit"> and <Route path="edit/">. You can still render two different UIs at those URLs, but you’ll have to do it server-side.

Note on <Link to> values

In v5, a <Link to> value that does not begin with / was ambiguous; it depends on what the current URL is. For example, if the current URL is /users, a v5 <Link to="me"> would render a <a href="/me">. However, if the current URL has a trailing slash, like /users/, the same <Link to="me"> would render <a href="/users/me">. This makes it difficult to predict how links will behave, so in v5 we recommended that you build links from the root URL (using match.url) and not use relative <Link to> values.

React Router v6 fixes this ambiguity. In v6, a <Link to="me"> will always render the same <a href>, regardless of the current URL.

For example, a <Link to="me"> that is rendered inside a <Route path="users"> will always render a link to /users/me, regardless of whether or not the current URL has a trailing slash. If you’d like to link to /me instead, you can go up one segment of the URL using .., like <Link to="../me">. The .. basically means “remove one segment of the current URL”, regardless of whether it has a trailing slash or not. Of course, you can always <Link to="/me"> if you’d like to use an absolute URL instead.

It may help to think about the current URL as if it were a directory path on the filesystem and <Link to> like the cd command line utility.

// If the current URL is /app/dashboard (with or without
// a trailing slash)
<Link to="stats">               // <a href="/app/dashboard/stats">
<Link to="../stats">            // <a href="/app/stats">
<Link to="../../stats">         // <a href="/stats">
<Link to="../../../stats">      // <a href="/stats">

// On the command line, if the current directory is /app/dashboard
cd stats                        // pwd is /app/dashboard/stats
cd ../stats                     // pwd is /app/stats
cd ../../stats                  // pwd is /stats
cd ../../../stats               // pwd is /stats

Note: The decision to ignore trailing slashes while matching and creating relative paths was not taken lightly by our team. We consulted with a number of our friends and clients (who are also our friends!) about it. We found that most of us don’t even understand how plain HTML relative links are handled with the trailing slash. Most people guessed it worked like cd on the command line (it does not). Also, HTML relative links don’t have the concept of nested routes, they only worked on the URL, so we had to blaze our own trail here a bit. @reach/router set this precendent and it has worked out well for a couple of years.

Use useRoutes instead of react-router-config

All of the functionality from v5’s react-router-config package has moved into core in v6. If you prefer/need to define your routes as JavaScript objects instead of using React elements, you’re going to love this.

function App() {
  let element = useRoutes([
    // These are the same as the props you provide to <Route>
    { path: '/', element: <Home /> },
    { path: 'dashboard', element: <Dashboard /> },
    { path: 'invoices',
      element: <Invoices />,
      // Nested routes use a children property, which is also
      // the same as <Route>
      children: [
        { path: ':id', element: <Invoice /> },
        { path: 'sent', element: <SentInvoices /> }
      ]
    },
    // Redirects use a redirectTo property to
    { path: 'home', redirectTo: '/' },
    // Not found routes work as you'd expect
    { path: '*', element: <NotFound /> }
  ]);

  // The returned element will render the entire element
  // hierarchy with all the appropriate context it needs
  return element;
}

Routes defined in this way follow all of the same semantics as <Routes>. In fact, <Routes> is really just a wrapper around useRoutes. Crazy, I know.

We encourage you to give both <Routes> and useRoutes a shot and decide for yourself which one you prefer to use. Honestly, we like and use them both.

If you had cooked up some of your own logic around data fetching and rendering server-side, we have a low-level matchRoutes function available as well similar to the one we had in react-router-config.

Use navigate instead of history

React Router v6 introduces a new navigation API that is synonymous with <Link> and provides better compatibility with suspense-enabled apps. We include both imperative and declarative versions of this API depending on your style and needs.

// This is a React Router v5 app
import { useHistory } from 'react-router-dom';

function App() {
  let history = useHistory();
  function handleClick() {
    history.push('/home')
  }
  return (
    <div>
      <button onClick={handleClick}>go home</button>
    </div>
  );
}

In v6, this app should be rewritten to use the navigate API. Most of the time this means changing useHistory to useNavigate and changing the history.push or history.replace callsite.

// This is a React Router v6 app
import { useNavigate } from 'react-router-dom';

function App() {
  let navigate = useNavigate();
  function handleClick() {
    navigate('/home')
  }
  return (
    <div>
      <button onClick={handleClick}>go home</button>
    </div>
  );
}

If you need to replace the current location instead of push a new one onto the history stack, use navigate(to, { replace: true }). If you need state, use navigate(to, { state }). You can think of the first arg to navigate as your <Link to> and the other arg as the replace and state props.

If you prefer to use a declarative API for navigation (ala v5’s Redirect component), v6 provides a Navigate component. Use it like:

import { Navigate } from 'react-router-dom';

function App() {
  return <Navigate to="/home" replace state={state} />;
}

If you’re currently using go, goBack or goForward from useHistory to navigate backwards and forwards, you should also replace these with navigate with a numerical argument indicating where to move the pointer in the history stack. For example, here is some code using v5’s useHistory hook:

// This is a React Router v5 app
import { useHistory } from 'react-router-dom';

function App() {
  const { go, goBack, goForward } = useHistory();

  return (
    <>
      <button onClick={() => go(-2)}>Go 2 pages back</button>
      <button onClick={goBack}>Go back</button>
      <button onClick={goForward}>Go forward</button>
      <button onClick={() => go(2)}>Go 2 pages forward</button>
    </>
  );
}

Here is the equivalent app with v6:

// This is a React Router v6 app
import { useNavigate } from 'react-router-dom';

function App() {
  const navigate = useNavigate();

  return (
    <>
      <button onClick={() => navigate(-2)}>Go 2 pages back</button>
      <button onClick={() => navigate(-1)}>Go back</button>
      <button onClick={() => navigate(1)}>Go forward</button>
      <button onClick={() => navigate(2)}>Go 2 pages forward</button>
    </>
  );
}

Again, one of the main reasons we are moving from using the history API directly to the navigate API is to provide better compatibility with React suspense. React Router v6 uses the useTransition hook at the root of your component hierarchy. This lets us provide a smoother experience when user interaction needs to interrupt a pending route transition, for example when they click a link to another route while a previously-clicked link is still loading. The navigate API is aware of the internal pending transition state and will do a REPLACE instead of a PUSH onto the history stack, so the user doesn’t end up with pages in their history that never actually loaded.

Note: You should still use a <Redirect> as part of your route config (inside a <Routes>). This change is only necessary for <Redirect>s that are used to navigate in response to user interaction.

Aside from suspense compatibility, navigate, like Link, supports relative navigation. For example:

// assuming we are at `/stuff`
function SomeForm() {
  let navigate = useNavigate()
  return (
    <form onSubmit={async (event) => {
      let newRecord = await saveDataFromForm(event.target)
      // you can build up the URL yourself
      navigate(`/stuff/${newRecord.id}`)
      // or navigate relative, just like Link
      navigate(`${newRecord.id}`)
    }}>{/* ... */}</form>
  )
}

Rename <Link component> to <Link as>

This is a simple renaming of a prop to better align with the common practice of other libraries in the React ecosystem including styled-components and Reach UI.

Get StaticRouter from react-router-dom/server

The StaticRouter component has moved into a new bundle: react-router-dom/server.

// change
import { StaticRouter } from 'react-router-dom';
// to
import { StaticRouter } from 'react-router-dom/server';

This change was made both to follow more closely the convention established by the react-dom package and to help users understand better what a <StaticRouter> is for and when it should be used (on the server).

What did we miss?

Despite my best attempts at being thorough (it took me 2 days to write this) I’m sure I missed something. If you follow this upgrade guide and find it’s missing something, please let us know. We are happy to help you figure out what to do with your v5 code to be able to upgrade and take advantage of all of the cool stuff in v6.

Good luck 🤘

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

How to Setup React Router v5 using React Hooks

React Router library makes the navigation experience of the client in your web page application more joyful, but how?!

React Router, indeed, prevent the page from being refreshed. Thus the blank page resulted from a refreshed page is not displayed while the user is navigating and routing through your web. This tool enables you to manipulate your web application routes through provided routing components and dynamic routing while the app is rendering.

How to start:
You need a React web app, to get started. If you don’t have, install create-react-app and launch a new project using it. Then you need to install react-router-dom, applying either npm or yarn.

npm install --save react-router-dom
yarn add react-router-dom

Now all the required components are installed. We are enabled to add any component to the App.js inside the router to build our unique web page. All these elements are the router children to which we specify their path. For instance, I add the components of Homepage, About, and Products inside the router where one can navigate through them. Also, React Router allows us to redirect our clients by a simple click on a button. To this purpose, import the Link to your component, define an onclick function for the button and redirect it to your intended path.

These are not all. There are other features in React Router. If you want to know how to install and benefit from it, join me in this YouTube video to decode the solution. I create the above-mentioned app and its components and explain all the features that we can use to improve it:

How to Setup React Router v5 using React Hooks

For today’s episode, I chose React Router V5 for our tutorial topic. We will dig into it and see how to configure it using Hooks to have a flexible and powerful routing system in our ReactJs apps. I believe this library is the best for routing in React but if you know a better one please share in comments.

By watching this video, you will learn how to install react-router-dom library and define your routes inside app.js file. You will see how to define required or optional parameters for each route and read the value in the component from useParams function. Finally, I will talk about how to show the page not found error to the user if the inserted route was not matched.
