if you want to pass props to a component inside a route, the simplest way is by utilizing the render
, like this:
<route exact path="/details/:id" render={(props) => <detailspage globalstore={globalstore} {...props} /> } />
you can access the props inside the detailpage
using:
this.props.match
this.props.globalstore
the {...props}
is needed to pass the original route's props, otherwise you will only get this.props.globalstore
inside the detailpage
.

try this.
<route exact path="/details/:id" render={(props)=>{return(
<detailspage id={props.match.params.id}/>)
}} />
in details page try this...
this.props.id

simple example with class, hoc and router v5
package.json
"react-router-dom": "5.3.1",
"react-router": "5.3.1",
"@types/react-router-dom": "5.3.3",
// yourcomponent.tsx
import react from 'react';
import { routecomponentprops, withrouter } from 'react-router';
export interface pathparams {
id: string;
}
export interface props extends routecomponentprops<pathparams> {}
export interface state {}
class yourcomponent extends react.component<props, state> {
constructor(props: props) {
super(props);
this.state = {};
console.log(props.match.params) // { id: 1 }
// typescript completions
console.log(props.match.params.id) // 1
}
render() {
return <></>;
}
}
export default withrouter(yourcomponent);
// app.tsx
import './app.css';
import react from 'react';
import { route, switch, router } from 'react-router-dom';
import yourcomponent from './yourcomponent';
function app(): jsx.element {
return (
<router>
<switch>
<route
path="/details/:id"
component={() => <yourcomponent />}
/>
</switch>
</router>
);
}
export default app;

if you are using class component, you are most likely to use gserjo suggestion. pass in the params via <route>
props to your target component:
exact path="/problem/:problemid" render={props => <problempage {...props.match.params} />}

this is for react-router-dom v6 (i highly suggest using functional components for this)
it's somewhat painful for react-router-dom to keep changing syntax and rules. but here goes nothing.
you can use both useparams
and useselector
to solve this
import { useparams } from 'react-router';
import { useselector } from 'react-redux';
const component = () => {
const { id } = useparams(); //returns the :id
const page = useselector((state) => state.something[id]); //returns state of the page
return <div>page detail</div>;
}
export default component;
but, the problem persist when you also have an action creator and you want to pass it as a props in connect
function
export const connect(mapstatetoprops, mapdispatchtoprops)(component)
since we are using useparams
, it won't be passed to mapstatetoprops
that we created
const mapstatetoprops = (state, ownprops) => {
console.log(ownprops) //wont recognize :id
//hence
return {
somereducers: state.somereducers[id] //would return an error: 'id' is not defined
};
};
on the other hand, you can't entirely ignore the connect
function since you need mapdispatchtoprops
to work with your component.
the workaround to this is to create a higher order component withrouter
function yourself. this was a deprecated react-router-dom helper.
//make this
import { useparams, uselocation, usenavigate } from 'react-router';
import { connect } from 'react-redux';
import { youractioncreator } from '../actioncreator';
const withrouter = (child) => {
return (props) => {
const location = uselocation();
const navigation = usenavigate();
const params = useparams();
return (
<child
{...props}
params={params}
navigate={navigate}
location={location}
/>
);
};
};
const component = () => {
// your component...
return <div> page detail </div>
};
export mapstatetoprops = (state, ownprops) => {
console.log(ownprops) // would contain the :id params
return {
//something
}
};
const mapdispatchtoprops = {
youractioncreator
}
export withrouter(connect(mapstatetoprops, mapdispatchtoprops)(component));

another solution is to use a state and lifecycle hooks in the routed component and a search statement in the to
property of the <link />
component. the search parameters can later be accessed via new urlsearchparams()
;
<link
key={id}
to={{
pathname: this.props.match.url + '/' + foo,
search: '?foo=' + foo
}} />
<route path="/details/:foo" component={detailspage}/>
export default class detailspage extends component {
state = {
foo: ''
}
componentdidmount () {
this.parsequeryparams();
}
componentdidupdate() {
this.parsequeryparams();
}
parsequeryparams () {
const query = new urlsearchparams(this.props.location.search);
for (let param of query.entries()) {
if (this.state.foo!== param[1]) {
this.setstate({foo: param[1]});
}
}
}
render() {
return(
<div>
<h2>{this.state.foo}</h2>
</div>
)
}
}

here's typescript version. works on "react-router-dom": "^4.3.1"
export const approuter: react.statelesscomponent = () => {
return (
<browserrouter>
<switch>
<route exact path="/problem/:problemid" render={props => <problempage {...props.match.params} />} />
<route path="/" exact component={app} />
</switch>
</browserrouter>
);
};
and component
export class problempage extends react.component<problemroutetokens> {
public render(): jsx.element {
return <div>{this.props.problemid}</div>;
}
}
where problemroutetokens
export interface problemroutetokens { problemid: string; }

use the component:
<route exact path="/details/:id" component={detailspage} />
and you should be able to access the id
using:
this.props.match.params.id
inside the detailspage
component
score:14
in addition to alexander lunas answer ... if you want to add more than one argument just use:
<route path="/details/:id/:title" component={detailspage}/>
export default class detailspage extends component {
render() {
return(
<div>
<h2>{this.props.match.params.id}</h2>
<h3>{this.props.match.params.title}</h3>
</div>
)
}
}
score:40
use render method:
<route exact path="/details/:id" render={(props) => (
<detailspage id={props.match.params.id}/>
)} />
and you should be able to access the id using:
this.props.id
inside the detailspage component
score:60
since react-router v5.1 with hooks:
import { useparams } from 'react-router';
export default function detailspage() {
const { id } = useparams();
}
score:134
i used this to access the id in my component:
<route path="/details/:id" component={detailspage}/>
and in the detail component:
export default class detailspage extends component {
render() {
return(
<div>
<h2>{this.props.match.params.id}</h2>
</div>
)
}
}
this will render any id inside an h2, hope that helps someone.
