Respond Router v6.6.1 with useNavigate
The useHistory() hook is present deprecated. If you are utilizing Respond Router 6, the appropriate manner to navigate programmatically is arsenic follows:
import { useNavigate } from "react-router-dom";function HomeButton() { const navigate = useNavigate(); function handleClick() { navigate("/home"); } return ( <button type="button" onClick={handleClick}> Go home </button> );}Respond Router v5.1.Zero with hooks
Location is a fresh useHistory hook successful Respond Router increased than 5.1.Zero, if you are utilizing Respond increased than Sixteen.Eight.Zero and purposeful elements.
import { useHistory } from "react-router-dom";function HomeButton() { const history = useHistory(); function handleClick() { history.push("/home"); } return ( <button type="button" onClick={handleClick}> Go home </button> );}Respond Router v4
With v4 of Respond Router, location are 3 approaches that you tin return to programmatic routing inside elements.
- Usage the
withRouterincreased-command constituent. - Usage creation and render a
<Route> - Usage the
context.
Respond Router is largely a wrapper about the history room. history handles action with the browser's window.history for you with its browser and hash histories. It besides offers a representation past which is utile for environments that don't person a planetary past. This is peculiarly utile successful cellular app improvement (react-native) and part investigating with Node.js.
A history case has 2 strategies for navigating: push and replace. If you deliberation of the history arsenic an array of visited areas, push volition adhd a fresh determination to the array and replace volition regenerate the actual determination successful the array with the fresh 1. Sometimes you volition privation to usage the push technique once you are navigating.
Successful earlier variations of Respond Router, you had to make your ain history case, however successful v4 the <BrowserRouter>, <HashRouter>, and <MemoryRouter> elements volition make a browser, hash, and representation cases for you. Respond Router makes the properties and strategies of the history case related with your router disposable done the discourse, nether the router entity.
1. Usage the withRouter increased-command constituent
The withRouter increased-command constituent volition inject the history entity arsenic a prop of the constituent. This permits you to entree the push and replace strategies with out having to woody with the context.
import { withRouter } from 'react-router-dom'// This also works with react-router-nativeconst Button = withRouter(({ history }) => ( <button type='button' onClick={() => { history.push('/new-location') }} > Click Me! </button>))2. Usage creation and render a <Route>
The <Route> constituent isn't conscionable for matching areas. You tin render a pathless path and it volition ever lucifer the actual determination. The <Route> constituent passes the aforesaid props arsenic withRouter, truthful you volition beryllium capable to entree the history strategies done the history prop.
import { Route } from 'react-router-dom'const Button = () => ( <Route render={({ history}) => ( <button type='button' onClick={() => { history.push('/new-location') }} > Click Me! </button> )} />)Three. Usage the discourse*
However you most likely ought to not
The past action is 1 that you ought to lone usage if you awareness comfy running with Respond's discourse exemplary (Respond's Discourse API is unchangeable arsenic of v16).
const Button = (props, context) => ( <button type='button' onClick={() => { // context.history.push === history.push context.history.push('/new-location') }} > Click Me! </button>)// You need to specify the context type so that it// is available within the componentButton.contextTypes = { history: React.PropTypes.shape({ push: React.PropTypes.func.isRequired })}1 and 2 are the easiest decisions to instrumentality, truthful for about usage circumstances, they are your champion bets.
Respond Router v6+ reply
TL;DR: You tin usage the fresh useNavigate hook.
import { useNavigate } from "react-router-dom";function Component() { let navigate = useNavigate(); // Somewhere in your code, e.g., inside a handler: navigate("/posts");}The useNavigate hook returns a relation which tin beryllium utilized for programmatic navigation.
Illustration from the Respond Router documentation:
import { useNavigate } from "react-router-dom";function SignupForm() { let navigate = useNavigate(); async function handleSubmit(event) { event.preventDefault(); await submitForm(event.target); navigate("../success", { replace: true }); // 'replace: true' will replace the current entry in // the history stack instead of adding a new one. } return <form onSubmit={handleSubmit}>{/* ... */}</form>;}Respond Router 5.1.Zero+ reply (utilizing hooks and Respond Sixteen.Eight oregon future))
You tin usage the useHistory hook connected useful elements and programmatically navigate:
import { useHistory } from "react-router-dom";function HomeButton() { let history = useHistory(); // Use history.push('/some/path') here};Respond Router Four.Zero.Zero+ reply
Successful Four.Zero and supra, usage the past arsenic a prop of your constituent.
class Example extends React.Component { // Use `this.props.history.push('/some/path')` here};Line: this.props.history does not be successful the lawsuit your constituent was not rendered by <Route>. You ought to usage <Route path="..." component={YourComponent}/> to person this.props.history successful YourComponent
Respond Router Three.Zero.Zero+ reply
Successful Three.Zero and supra, usage the router arsenic a prop of your constituent.
class Example extends React.Component { // Use `this.props.router.push('/some/path')` here};Respond Router 2.Four.Zero+ reply
Successful 2.Four and supra, usage a larger-command constituent to acquire the router arsenic a prop of your constituent.
import { withRouter } from 'react-router';class Example extends React.Component { // Use `this.props.router.push('/some/path')` here};// Export the decorated classvar DecoratedExample = withRouter(Example);// PropTypesExample.propTypes = { router: React.PropTypes.shape({ push: React.PropTypes.func.isRequired }).isRequired};Respond Router 2.Zero.Zero+ reply
This interpretation is backwards appropriate with 1.x, truthful location isn't immoderate demand to an improve usher. Conscionable going done the examples ought to beryllium bully adequate.
That stated, if you want to control to the fresh form, location's a browserHistory module wrong the router that you tin entree with
import { browserHistory } from 'react-router'
Present you person entree to your browser past, truthful you tin bash issues similar propulsion, regenerate, and so on... Similar:
browserHistory.push('/some/path')
Additional speechmaking:
Respond Router 1.x.x reply
I volition not spell into upgrading particulars. You tin publication astir that successful the improve usher.
The chief alteration astir the motion present is the alteration from Navigation mixin to History. Present it's utilizing the browser historyAPI to alteration path truthful we volition usage pushState() from present connected.
Present's an illustration utilizing Mixin:
var Example = React.createClass({ mixins: [ History ], navigateToHelpPage () { this.history.pushState(null, `/help`); }})Line that this History comes from the rackt/past task, not from Respond Router itself.
If you don't privation to usage Mixin for any ground (possibly due to the fact that of an ES6 people), past you tin entree the past that you acquire from the router from this.props.history. It volition beryllium lone accessible for the elements rendered by your Router. Truthful, if you privation to usage it successful immoderate kid elements it wants to beryllium handed behind arsenic an property through props.
You tin publication much astir the fresh merchandise astatine their 1.Zero.x documentation.
Present is a aid leaf particularly astir navigating extracurricular your constituent.
It recommends grabbing a mention history = createHistory() and calling replaceState connected that.
Respond Router Zero.Thirteen.x reply
I bought into the aforesaid job and may lone discovery the resolution with the Navigation mixin that comes with Respond Router.
Present's however I did it
import React from 'react';import {Navigation} from 'react-router';let Authentication = React.createClass({ mixins: [Navigation], handleClick(e) { e.preventDefault(); this.transitionTo('/'); }, render(){ return (<div onClick={this.handleClick}>Click me!</div>); }});I was capable to call transitionTo() with out the demand to entree .context
Oregon you may attempt the fancy ES6 class:
import React from 'react';export default class Authentication extends React.Component { constructor(props) { super(props); this.handleClick = this.handleClick.bind(this); } handleClick(e) { e.preventDefault(); this.context.router.transitionTo('/'); } render(){ return (<div onClick={this.handleClick}>Click me!</div>); }}Authentication.contextTypes = { router: React.PropTypes.func.isRequired};Respond-Router-Redux
Line: if you're utilizing Redux, location is different task referred to asRespond-Router-Redux that offers youredux bindings for ReactRouter, utilizing slightly the aforesaid attack thatRespond-Redux does
Respond-Router-Redux has a fewer strategies disposable that let for elemental navigating from wrong act creators. These tin beryllium peculiarly utile for group that person current structure successful Respond Autochthonal, and they want to make the most of the aforesaid patterns successful Respond Internet with minimal boilerplate overhead.
Research the pursuing strategies:
push(location)replace(location)go(number)goBack()goForward()
Present is an illustration utilization, with Redux-Thunk:
./actioncreators.js
import { goBack } from 'react-router-redux'export const onBackPress = () => (dispatch) => dispatch(goBack())./viewcomponent.js
<button disabled={submitting} className="cancel_button" onClick={(e) => { e.preventDefault() this.props.onBackPress() }}> CANCEL</button>Respond Router is a almighty implement for managing navigation successful Respond functions. Frequently, you'll demand to navigate programmatically, not conscionable done person clicks connected hyperlinks, however besides arsenic a consequence of signifier submissions, API calls, oregon another exertion logic. This station delves into the antithetic methods you tin accomplish programmatic navigation utilizing Respond Router, guaranteeing your exertion flows easily and responds dynamically to person actions and information adjustments. Knowing these methods is indispensable for gathering strong and person-affable Respond functions, arsenic it permits for higher power complete the person's education and the exertion's behaviour.
Knowing Programmatic Navigation successful Respond Router
