Please I need help on react-router-dom, I am new to the library and can seem to find any solution since. I am getting three results from an api call, in which I map over the data to render it on UI, now what I need now is that if I click on a row on one of this list, I want it to take me to a screen showing the details of only that single thing I clicked on.
import React, { Component } from "react";
export default class User extends Component {
state = { userDetails: "" };
componentDidMount() {
axios.get(`https://urlforapi.com`)
.then(({ data }) => {
this.setState({
userDetails: data
});
});
}
render() {
const { userDetails } = this.state;
return (
<div>
{userDetails
? userDetails.map(info => {
return (
<Link to="/home/userDetails">
<div key={info.id}>
<p>{info.name}</p>
</div>
<div>
<p>{info.age}</p>
</div>
<div>
<p>{info.description}</p>
</div>
</Link>
);
})
: null}
</div>
);
}
}
Option 1: Pass Route State
Send the state in the route transition.
Using react-router-dom v5
Declarative Navigation - Link to
You can pass some state unique to the mapped entry, like info.id along with the route push that happens when the link is clicked. This obfuscates the data from the user as you aren't leaking information out to the ui (i.e. the browser).
<Link
to={{
pathname: '/home/userDetails',
state: { infoId: info.id },
}}
>
Imperative Navigation - useHistory hook
const history = useHistory();
...
history.push({
pathname: '/home/userDetails',
state: { infoId: info.id },
});
You can then unpack the state from the location prop/object on the component being returned by that route. Use guards in case a user has navigated to '/home/userDetails' from elsewhere, as state may be undefined.
If passed route props:
props.location && props.location.state && props.location.state.infoId
or
props.location?.state?.infoId
If using function components then you can also use the useLocation React hook:
const { state: { infoId } = {} } = useLocation();
Using react-router-dom v6
Declarative Navigation - Link or Navigate components
The link API changed a bit in v6, the state is now a prop.
<Link
to='/home/userDetails'
state={{ infoId: info.id }}
>
or using the Navigate component, the spiritual successor/replacement to the v5 Redirect component
<Navigate
to="/home/userDetails"
state={{ infoId: info.id }}
/>
Imperative Navigation - useNavigate hook
const navigate = useNavigate();
...
navigate('/home/userDetails', { state: { infoId: info.id } });
You can then unpack the state from the location object on the component being returned by that route. Use guards in case a user has navigated to '/home/userDetails' from elsewhere, as state may be undefined.
const { state: { infoId } = {} } = useLocation();
Option 2: Pass Something in the URL path
<Link to={`/home/userDetails/${info.id}`>
or (RRDv5)
const history = useHistory();
...
history.push(`/home/userDetails/${info.id}`);
or (RRDv6)
const navigate = useNavigate();
...
navigate(`/home/userDetails/${info.id}`);
And retrieve the param from the match prop in the returned route component. For example if the route looks like this:
Using react-router-dom v5
<Route path="/home/userDetails/:infoId" component={Detail} />
Then in the component get id from the match route prop:
props.match.params.infoId
And in the case of function components, the useParams React hook:
const { infoId } = useParams();
Using react-router-dom v6
<Route path="/home/userDetails/:infoId" element={<Detail />} />
There is only the useParams hook in v6, there are no route props.
const { infoId } = useParams();
The user can see this, but you don't have to use the guard pattern to access since by definitions it'll be defined by the route (though infoID can still be defined if the user types in an invalid id).
Option 3: Pass Something in the URL queryString
Using react-router-dom v5
Declarative Navigation - Link to
<Link
to={{
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
}}
>
Imperative Navigation - useNavigate hook
const history = useHistory();
...
history.push({
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
});
You can then unpack the infoId query param from the location prop/object on the component being returned by that route.
If passed route props:
props.location && props.location.search
or
props.location?.search
If using function components then you can also use the useLocation React hook:
const { search } = useLocation();
Then create a URLSearchParams object and access the infoId parameter.
const searchParams = new URLSearchParams(search);
const infoId = searchParams.get("infoId");
Using react-router-dom v6
Declarative Navigation - Link or Navigate components
The link API changed a bit in v6, the state is now a prop.
<Link
to={{
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
}}
>
or using the Navigate component, the spiritual successor/replacement to the v5 Redirect component
<Navigate
to={{
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
}}
/>
Imperative Navigation - useNavigate hook
const navigate = useNavigate();
...
navigate({
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
});
You can then unpack the infoId query param from the useSearchParams hook.
const [searchParams] = useSearchParams();
const infoId = searchParams.get("infoId");
New in v6.4.0 is the createSearchParams utility function.
<Link
to={{
pathname: '/home/userDetails',
search: createSearchParams({ infoId: info.id}),
}}
>
or
navigate({
pathname: '/home/userDetails',
search: createSearchParams({ infoId: info.id}),
});
But I'm using a React class component
In react-router-dom#6 the route props and withRouter HOC were removed. To access the old "route props" in RRDv6 you'll need to create your own withRouter HOC replacement that can use the React hooks and inject props that can be used in React class components.
import { useLocation, useParams, /* other hooks */ } from 'react-router-dom';
const withRouter = WrappedComponent => props => {
const location = useLocation();
const params = useParams();
// other hooks
return (
<WrappedComponent
{...props}
{...{ location, params, /* other hooks */ }}
/>
);
};
Decorate the component and access props:
class MyComponent extends React.Component {
...
this.props.location.state;
this.props.params;
...etc...
...
};
export default withRouter(MyComponent);
References
location
match
useLocation v5
useLocation v6
useParams v5
useParams v6
useSearchParams v6.4.0
You can use path params option of react-router-dom .
Example
import React from 'react'
import { BrowserRouter as Router, Route } from 'react-router-dom'
import Topic from '../topic'
export default function App() {
return (
<Router>
<div>
<Route path="/topic/:name" component={Topic} />
</div>
</Router>
);
}
Pass the params:
import React, { Component } from "react";
import { Link } from 'react-router-dom'
export default class Topics extends Component {
render() {
return <Link to="/topic/someTopicName">Some Topic</Link>;
}
}
Access router params in the component
import React from 'react'
export default function Topic(props) {
return <h1>{props.match.params.name}</h1>
}
This is how you can pass data to navigated component
<Link
to={{
pathname: '/home/userDetails',
state: {infoId: info.id},
}}
>
And access like this in navigated component
if it's class based component.
this.props.location.state
if it's functional component
props.location.state
If your using function component in your react application. You can follow below steps
Main page:
<Link
to={{
pathname: '/your/path',
state: {
data: "your data"
},
}}
>
In your child page or page you wanted to route:
use useLocation (version 5.+) hook
const emp = useLocation()
console.log(emp)
Output
{
state: {
data: "your data"
}
}
**Pass the state:**
import { Link} from "react-router-dom";
<Link to="/home/userDetails" state: { userDetails:'Name'} }>
**Received the state:**
import { useLocation} from 'react-router-dom';
const location = useLocation();
const userDetails= location.state.userDetails;

Option 2: Pass Something in the URL path
<Link to={`/home/userDetails/${info.id}`>
or (RRDv5)
const history = useHistory();
...
history.push(`/home/userDetails/${info.id}`);
or (RRDv6)
const navigate = useNavigate();
...
navigate(`/home/userDetails/${info.id}`);
And retrieve the param from the match prop in the returned route component. For example if the route looks like this:
Using react-router-dom v5
<Route path="/home/userDetails/:infoId" component={Detail} />
Then in the component get id from the match route prop:
props.match.params.infoId
And in the case of function components, the useParams React hook:
const { infoId } = useParams();
Using react-router-dom v6
<Route path="/home/userDetails/:infoId" element={<Detail />} />
There is only the useParams hook in v6, there are no route props.
const { infoId } = useParams();
The user can see this, but you don't have to use the guard pattern to access since by definitions it'll be defined by the route (though infoID can still be defined if the user types in an invalid id).
Option 3: Pass Something in the URL queryString
Using react-router-dom v5
Declarative Navigation - Link to
<Link
to={{
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
}}
>
Imperative Navigation - useNavigate hook
const history = useHistory();
...
history.push({
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
});
You can then unpack the infoId query param from the location prop/object on the component being returned by that route.
If passed route props:
props.location && props.location.search
or
props.location?.search
If using function components then you can also use the useLocation React hook:
const { search } = useLocation();
Then create a URLSearchParams object and access the infoId parameter.
const searchParams = new URLSearchParams(search);
const infoId = searchParams.get("infoId");
Using react-router-dom v6
Declarative Navigation - Link or Navigate components
The link API changed a bit in v6, the state is now a prop.
<Link
to={{
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
}}
>
or using the Navigate component, the spiritual successor/replacement to the v5 Redirect component
<Navigate
to={{
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
}}
/>
Imperative Navigation - useNavigate hook
const navigate = useNavigate();
...
navigate({
pathname: '/home/userDetails',
search: `?infoId=${info.id}`,
});
You can then unpack the infoId query param from the useSearchParams hook.
const [searchParams] = useSearchParams();
const infoId = searchParams.get("infoId");
New in v6.4.0 is the createSearchParams utility function.
<Link
to={{
pathname: '/home/userDetails',
search: createSearchParams({ infoId: info.id}),
}}
>
or
navigate({
pathname: '/home/userDetails',
search: createSearchParams({ infoId: info.id}),
});
But I'm using a React class component
In react-router-dom#6 the route props and withRouter HOC were removed. To access the old "route props" in RRDv6 you'll need to create your own withRouter HOC replacement that can use the React hooks and inject props that can be used in React class components.
import { useLocation, useParams, /* other hooks */ } from 'react-router-dom';
const withRouter = WrappedComponent => props => {
const location = useLocation();
const params = useParams();
// other hooks
return (
<WrappedComponent
{...props}
{...{ location, params, /* other hooks */ }}
/>
);
};
Decorate the component and access props:
class MyComponent extends React.Component {
...
this.props.location.state;
this.props.params;
...etc...
...
};
export default withRouter(MyComponent);
References
location
match
useLocation v5
useLocation v6
useParams v5
useParams v6
useSearchParams v6.4.0
You can use path params option of react-router-dom .
Example
import React from 'react'
import { BrowserRouter as Router, Route } from 'react-router-dom'
import Topic from '../topic'
export default function App() {
return (
<Router>
<div>
<Route path="/topic/:name" component={Topic} />
</div>
</Router>
);
}
Pass the params:
import React, { Component } from "react";
import { Link } from 'react-router-dom'
export default class Topics extends Component {
render() {
return <Link to="/topic/someTopicName">Some Topic</Link>;
}
}
Access router params in the component
import React from 'react'
export default function Topic(props) {
return <h1>{props.match.params.name}</h1>
}
This is how you can pass data to navigated component
<Link
to={{
pathname: '/home/userDetails',
state: {infoId: info.id},
}}
>
And access like this in navigated component
if it's class based component.
this.props.location.state
if it's functional component
props.location.state
If your using function component in your react application. You can follow below steps
Main page:
<Link
to={{
pathname: '/your/path',
state: {
data: "your data"
},
}}
>
In your child page or page you wanted to route:
use useLocation (version 5.+) hook
const emp = useLocation()
console.log(emp)
Output
{
state: {
data: "your data"
}
}
**Pass the state:**
import { Link} from "react-router-dom";
<Link to="/home/userDetails" state: { userDetails:'Name'} }>
**Received the state:**
import { useLocation} from 'react-router-dom';
const location = useLocation();
const userDetails= location.state.userDetails;
Please I need help on react-router-dom, I am new to the library and can seem to find any solution since. I am getting three results from an api call, in which I map over the data to render it on UI, now what I need now is that if I click on a row on one of this list, I want it to take me to a screen showing the details of only that single thing I clicked on.
import React, { Component } from "react";
export default class User extends Component {
state = { userDetails: "" };
componentDidMount() {
axios.get(`https://urlforapi.com`)
.then(({ data }) => {
this.setState({
userDetails: data
});
});
}
render() {
const { userDetails } = this.state;
return (
<div>
{userDetails
? userDetails.map(info => {
return (
<Link to="/home/userDetails">
<div key={info.id}>
<p>{info.name}</p>
</div>
<div>
<p>{info.age}</p>
</div>
<div>
<p>{info.description}</p>
</div>

);
})
: null}

);
}
}
Option 1: Pass Route State
Send the state in the route transition.
Using react-router-dom v5
Declarative Navigation - Link to
You can pass some state unique to the mapped entry, like info.id along with the route push that happens when the link is clicked. This obfuscates the data from the user as you aren't leaking information out to the ui (i.e. the browser).
<Link
to={{
pathname: '/home/userDetails',
state: { infoId: info.id },
}}
>
Imperative Navigation - useHistory hook
const history = useHistory();
...
history.push({
pathname: '/home/userDetails',
state: { infoId: info.id },
});
You can then unpack the state from the location prop/object on the component being returned by that route. Use guards in case a user has navigated to '/home/userDetails' from elsewhere, as state may be undefined.
If passed route props:
props.location && props.location.state && props.location.state.infoId
or
props.location?.state?.infoId

state={{ infoId: info.id }}
/>
Imperative Navigation - useNavigate hook
const navigate = useNavigate();

navigate('/home/userDetails', { state: { infoId: info.id } });
