react-use-navigate v0.1.1

react-use-navigate

Easy, flexible, and expressive hook based navigation in React.

Features

• Tiny. Simple. Expressive. 1.5kb gzipped.
• TypeScript ready
• React framework agnostic (Next.js, Gatsby, React Router, Reach Router, etc.)
• Glob pattern matching support

Motivation

Often times we want to navigate pages conditionally. This can easily turn into a bunch of if else statements and regex matching. Here's some code that redirects a logged out user to /login if they on a page under the /app directory. If they are logged in but not in the app, they are redirected to the app dashboard.

useEffect(() => {
  const inApp = new RegEx(`/${location.hostname}\/app\/([0-9A-Za-z]+\/?)+/`)
  if(!isLoggedIn && inApp) {
    return goTo('/login')
  }
  if(isLoggedIn && !inApp) {
    return goTo('/app/dashboard')
  }
}, [isLoggedIn])

Not complicated to follow (aside from the regex), but for something so easy to express in words, it sure doesn't look it. Using the useNavigate() hook, here's what the same code would look like:

const { replace } = useNavigate()

useEffect(() => {
  replace({
    goTo: '/login',
    when: !isLoggedIn,
    onPaths: ['/app/**'], // glob pattern matching goodness
    otherwiseGoTo: '/app/dashboard', // this will only trigger if when === false AND path requirements fail
  })
}, [isLoggedIn])

This can almost be read as sentence, roughly translating to, "go to /login when user is not logged in while on any app directory. Otherwise, go to the app dashboard."

But what if we want to navigate a user when they aren't on a page in a particular directory? For example, maybe we have multiple apps like /analytics and /editor. Perhaps we want to just be general and say "send the user to login if they aren't on a marketing page". No problem, here's the same code as above with a slight modification:

const { replace } = useNavigate()

useEffect(() => {
  replace({
    goTo: '/login',
    when: !isLoggedIn,
    notOnPaths: ['/marketing/**'], // navigates when a user isn't on a matching page
  })
}, [isLoggedIn])

Installation

yarn add react-use-navigate
npm install react-use-navigate

This package has a peer dependency on React and React DOM > 16.8.0 (basically you need react hooks).

Setup

This hook doesn't care how navigation works, it just asks that you provide the logic for the basic navigation methods push, replace, and back.

This can be done with a config object in the NavigateProvider. Below are a few examples in different frameworks.

Using React Router

import { NavigateProvider } from 'react-use-navigate'

const App = () => {
  const history = useHistory()
  
  const config = {
    push: history.push,
    back: history.back,
    replace: history.replace
  }

  return (
    <NavigateProvider {...config}>
      <RootComponent/>
    </NavigateProvider>
  )
}

Using Next.js

import { NavigateProvider } from 'react-use-navigate'

function MyApp({ Component, pageProps }) {
  const router = useRouter()

  const config = {
    push: router.push,
    back: router.back,
    replace: router.replace
  }

  return (
    <NavigateProvider {...config}>
      <Component {...pageProps} />
    </NavigateProvider>
  )
}

API Reference

useNavigate()

const { push, back, replace } = useNavigate()

Each navigation method uses the same paramters:

type UseNavigateProps = {
  when?: boolean
  goTo?: string
  onPaths?: string[] // array of globs
  notOnPaths?: string[]
  otherwiseGoTo?: string
}
