Usage

Basic

Provides GuardConfigProvider in BrowserRouter, and you can use it like react-router (compatible with the apis of react-router).

import { BrowserRouter } from 'react-router-dom'
import {
  GuardConfigProvider,
  GuardedRoute,
  GuardedRoutes,
} from 'react-router-guarded-routes'

export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        <GuardedRoutes>
          <GuardedRoute element={<div>foo</div>} path="/foo" />
          <GuardedRoute element={<div>bar</div>} path="/bar/*">
            <GuardedRoute element={<div>baz</div>} path="/bar/baz" />
          </GuardedRoute>
        </GuardedRoutes>
      </GuardConfigProvider>
    </BrowserRouter>
  )
}

Use hooks:

import {
  GuardedRouteObject,
  useGuardedRoutes,
} from 'react-router-guarded-routes'

const routes: GuardedRouteObject[] = [
  { path: '/foo', element: <div>foo</div> },
  {
    path: '/bar/*',
    element: <div>bar</div>,
    children: [{ path: '/bar/baz', element: <div>baz</div> }],
  },
]

function Routes() {
  return <GuardedRoutes>{useGuardedRoutes([routes])}</GuardedRoutes>
}

export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        <Routes />
      </GuardConfigProvider>
    </BrowserRouter>
  )
}

Guarding

You can provide GuardProvider with multiple guards middleware for route guarding, GuardProvider can receive an array of guards and a fallback element (can be used to load loading state).

import { BrowserRouter } from 'react-router-dom'
import {
  GuardConfigProvider,
  GuardedRoute,
  GuardedRoutes,
  GuardMiddleware,
  GuardProvider,
} from 'react-router-guarded-routes'

const logGuard: GuardMiddleware = (to, from, next) => {
  console.log(to) // { location, matches, route }
  console.log(from)
  next() // call next function to run the next middleware or show the route element, it accepts the same parameters as navigate (useNavigate()) and behaves consistently.
}

// you can use object to determine whether you need to register middleware
const barGuard: GuardMiddleware = {
  handler: (to, from, next) => {
    console.log('bar')
    next()
  },
  register: (to, from) => {
    // only matched with `/bar` can be executed.
    if (to.location.pathname.startsWith('/bar')) {
      return true
    }
    return false
  },
}

const guards = [logGuard, barGuard]

export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        {/* Guard all routes below. */}
        <GuardProvider fallback={<div>loading...</div>} guards={guards}>
          <GuardedRoutes>
            <GuardedRoute element={<div>foo</div>} path="/foo" />
            <GuardedRoute element={<div>bar</div>} path="/bar/*">
              <GuardedRoute element={<div>baz</div>} path="/bar/baz" />
            </GuardedRoute>
          </GuardedRoutes>
        </GuardProvider>
      </GuardConfigProvider>
    </BrowserRouter>
  )
}

Of course, you can also set up separate fallbacks and guards for each route.

import { BrowserRouter, Outlet } from 'react-router-dom'
import {
  GuardConfigProvider,
  GuardedRoute,
  GuardedRoutes,
  GuardMiddleware,
  GuardProvider,
} from 'react-router-guarded-routes'

const logGuard: GuardMiddleware = (to, from, next) => {
  console.log(to, from)
  next()
}

const fooGuard: GuardMiddleware = (to, from, next) => {
  console.log('foo')
  next()
}

const guards = [logGuard]
const fooGuards = [fooGuard]

export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        <GuardProvider fallback={<div>loading...</div>} guards={guards}>
          <GuardedRoutes>
            <GuardedRoute
              fallback={<div>loading foo...</div>}
              guards={fooGuard}
              element={<div>foo</div>}
              path="/foo"
            />
            <GuardedRoute
              element={
                <div>
                  bar
                  <Outlet />
                </div>
              }
              path="/bar/*"
            >
              <GuardedRoute element={<div>baz</div>} path="/bar/baz" />
            </GuardedRoute>
          </GuardedRoutes>
        </GuardProvider>
      </GuardConfigProvider>
    </BrowserRouter>
  )
}

You can also call next.ctx('ctx value') to transfer contextual information, and get it by ctxValue in the next guard middleware. The guard middleware is executed from outside to inside, left to right.

<GuardConfigProvider>
  <GuardProvider
    fallback={<div>loading...</div>}
    guards={(to, from, next) => {
      next.ctx('ctx value')
    }}
  >
    <GuardedRoutes>
      <GuardedRoute
        guards={(to, from, next, { ctxValue }) => {
          console.log(ctxValue) // ctx value
          next()
        }}
        element={<div>foo</div>}
        path="/foo"
      />
    </GuardedRoutes>
  </GuardProvider>
</GuardConfigProvider>

And call next.end() to ignore remaining middleware.

<GuardConfigProvider>
  <GuardProvider
    fallback={<div>loading...</div>}
    guards={
      ((to, from, next) => {
        next.end()
      },
      () => {
        console.log('will not be called')
      })
    }
  >
    <GuardedRoutes>
      <GuardedRoute
        guards={() => {
          console.log('will not be called')
        }}
        element={<div>foo</div>}
        path="/foo"
      />
    </GuardedRoutes>
  </GuardProvider>
</GuardConfigProvider>

Components

GuardConfigProvider

The GuardConfigProvider has configuration about routing, should not be used more than one in an app, make sure it's at the topmost level inside the Router (BrowserRouter and HashRouter).

And it provides APIs for whether to run guard middleware and whether to display the fallback element:

Props

import React from 'react'

export interface GuardConfigProviderProps {
  enableGuard?: (
    location: ToGuardRouteOptions,
    prevLocation: FromGuardRouteOptions
  ) => Promise<boolean> | boolean
  enableFallback?: (
    location: ToGuardRouteOptions,
    prevLocation: FromGuardRouteOptions
  ) => boolean
  children: React.ReactNode
}

Prop	Optional	Default	Description
`enableGuards`	Yes	(to, from) => to.location.pathname !== from.location?.pathname	whether to run guard middleware
`enableFallback`	Yes	() => true	whether to display the fallback element

Setup

import { BrowserRouter } from 'react-router-dom'
import { GuardConfigProvider } from 'react-router-guarded-routes'
export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        {
          // routes
        }
      </GuardConfigProvider>
    </BrowserRouter>
  )
}

GuardProvider

It provides public fallback element and guard middleware for GuardedRoute.

Props

import React from 'react'

export interface GuardProviderProps {
  fallback?: React.ReactElement
  useInject?: (
    to: ToGuardRouteOptions,
    from: FromGuardRouteOptions
  ) => Record<string, any>
  guards?: GuardedRouteConfig['guards']
  children: React.ReactNode
}

Prop	Optional	Description
`fallback`	Yes	a fallback element to show when a `GuardedRoute` run guard middleware
`useInject`	Yes	an injected value (React hooks can be used) for guard middleware to use, will be automatically merged the values of nested `GuardProvider`
`guards`	Yes	the guards to set for routes inside the `GuardProvider`

Setup

import { BrowserRouter } from 'react-router-dom'
import {
  GuardConfigProvider,
  GuardedRoute,
  GuardedRoutes,
  GuardMiddleware,
  GuardProvider,
} from 'react-router-guarded-routes'

const logGuard: GuardMiddleware = (to, from, next) => {
  console.log(to, from)
  next()
}

export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        <GuardProvider fallback={<div>loading...</div>} guards={[logGuard]}>
          <GuardedRoutes>
            <GuardedRoute element={<div>foo</div>} path="/foo" />
          </GuardedRoutes>
        </GuardProvider>
      </GuardConfigProvider>
    </BrowserRouter>
  )
}

Use nested GuardProvider:

<GuardConfigProvider>
  <GuardProvider fallback={<div>loading...</div>}>
    <GuardedRoutes>
      <GuardedRoute element={<div>foo</div>} path="/foo" />
      <GuardProvider fallback={<div>loading2...</div>}>
        <GuardedRoute
          element={
            <div>
              bar
              <Outlet />
            </div>
          }
          path="/bar/*"
        >
          <GuardedRoute element={<div>baz</div>} path="/bar/baz" />
        </GuardedRoute>
      </GuardProvider>
    </GuardedRoutes>
  </GuardProvider>
</GuardConfigProvider>

Inject value:

import { createContext } from 'react'
import { BrowserRouter } from 'react-router-dom'
import {
  GuardConfigProvider,
  GuardedRoute,
  GuardedRoutes,
  GuardProvider,
} from 'react-router-guarded-routes'

export const AuthContext = createContext({
  isLogin: false,
})

export function useAuth() {
  return useContext(AuthContext)
}

export default function App() {
  return (
    <BrowserRouter>
      <AuthContext>
        <GuardConfigProvider>
          <GuardProvider
            fallback={<div>loading...</div>}
            useInject={useAuth}
            guards={[
              (to, from, next, { injectedValue }) => {
                console.log(injectedValue) // { isLogin: false }
                next()
              },
            ]}
          >
            <GuardedRoutes>
              <GuardedRoute element={<div>foo</div>} path="/foo" />
            </GuardedRoutes>
          </GuardProvider>
        </GuardConfigProvider>
      </AuthContext>
    </BrowserRouter>
  )
}

GuardedRoutes

The GuardedRoutes component acts as a replacement for the default Routes component provided by React Router.

Props

import { RoutesProps } from 'react-router'

export interface GuardedRoutesProps extends RoutesProps {}

Setup

<BrowserRouter>
  <GuardConfigProvider>
    <GuardedRoutes>
      <GuardedRoute element={<div>foo</div>} path="/foo" />
    </GuardedRoutes>
  </GuardConfigProvider>
</BrowserRouter>

GuardedRoute

The GuardedRoute component acts as a replacement for the default Route component provided by React Router, allowing for routes to use guard middleware and accepting the same props as regular Route.

Props

import { Route } from 'react-router'
type RouteProps = Parameters<typeof Route>[0]

export type GuardedRouteProps = RouteProps & GuardedRouteConfig

The following table explains the guard-specific props for this component.

Prop	Optional	Default	Description
`fallback`	Yes		a fallback element to show when a `GuardedRoute` run guard middleware. (it will override the fallback provided by `GuardProvider`)
`guards`	Yes		the guards to set for the route

Setup

<GuardedRoutes>
  <GuardedRoute
    element={<div>foo</div>}
    path="/foo"
    fallback={<div>loading...</div>}
    guards={[
      (to, from, next) => {
        next()
      },
    ]}
  />
</GuardedRoutes>

Hooks

useGuardedRoutes

The useGuardedRoutes hook acts as a replacement for the default useRoutes hook provided by React Router, and additionally provides fallback and guards properties for each member.

Props

import { useRoutes } from 'react-router'

type LocationArg = Parameters<typeof useRoutes>[1]

export function useGuardedRoutes(
  guardedRoutes: GuardedRouteObject[],
  locationArg?: LocationArg
): ReturnType<typeof useRoutes>

Setup

import {
  GuardedRouteObject,
  useGuardedRoutes,
} from 'react-router-guarded-routes'
const routes: GuardedRouteObject[] = [
  {
    path: '/foo',
    element: <div>foo</div>,
    fallback: <div>loading foo...</div>,
    guards: [(to, from, next) => next()],
  },
]

function Routes() {
  return <>{useGuardedRoutes(routes)}</>
}

export default function App() {
  return (
    <BrowserRouter>
      <GuardConfigProvider>
        <GuardProvider fallback={<div>loading...</div>}>
          <Routes>
        </GuardProvider>
      </GuardConfigProvider>
    </BrowserRouter>
  )
}
