I have been learning about React Router have run into some issues while I was trying to implement a dynamic page creation based on the slugs that I receive from my fetch api call.
basically, I'm trying to redirect user to a new page after they click on a link - This new page will be a new component and I will make a new api call on this component with the slug as my search parameter.
However I'm struggling to dynamically change pages based on slugs.
Here is the component (BoxScore.js) in which I make the initial fetch and display data -
import React from "react";
import { useEffect, useState } from "react";
import { Link } from "react-router-dom";
const BoxScore = () => {
const [users, setUsers] = useState([]);
const [pageNumber, setPageNumber] = useState(1);
useEffect(() => {
fetch(
`myfetchapihere.com`
)
.then((response) => {
return response.json();
})
.then((data) => {
setUsers(data);
console.log(data);
setPageNumber(pageNumber);
});
}, [pageNumber]);
return (
<> {users.map((user) => (
<div
className="column"
key={user.id}
id={user.id}>
<div className="inner">
<div className="flex">
<h2 className="uk-text-small">
<Link to={user.slug} className="h2 link" id={user.slug}>
{user.name}
</Link>
</div>
</div></div>
)}
</>);
In my App.js I have react router set up -
<Routes>
<Route path="boxscore/:slug" element={<BoxScore />}>
<Route path=":slug" element={<OneScore />} />
</Route>
</Routes>
My OneScore component which isn't being rendered on the click of the link I set up in the Boxscore component -
import React from 'react'
import BoxScore from './Boxscore'
import { useParams } from "react-router";
import {useEffect} from 'react'
function OneScore() {
const { slug } = useParams();
useEffect(() => {
// Fetch post using the postSlug
console.log({slug});
}, [slug]);
return (
<div>
Hiii
</div>
)
}
export default OneScore
EDIT - I have managed to make the linking work thanks to @DrewReese comments however, the only issue remains now is that after the url is changed to (ex- www.a.com/boxscore/) the 'OneScore' component is not rendered instead the same BoxScore remains just the url is changed.
Instead of a raw anchor (<a />) tag use the Link or NavLink component. These link components work with the routing context being provided by the router. Using the anchor tag will reload the app, which very likely isn't what you want to occur.
import { Link } from 'react-router-dom';
...
{users.map((user) => (
<div
className="column"
key={user.id}
id={user.id}
>
<div className="inner">
<div className="flex">
<Link to={user.slug} className="h2link" id={user.slug}>
<h2 className="uk-text-small">{user.name}</h2>
</Link>
</div>
</div>
</div>
)};
The routed component should use the useParams hook to access the route's slug path param and an useEffect hook to rerun any logic that depends on this slug value.
import { useEffect } from 'react';
import { useParams } from 'react-router-dom';
...
const { slug } = useParams();
useEffect(() => {
// "make a new api call on this component with the slug as my search parameter"
}, [slug]);
Look into useParams to get the slug from the url. https://v5.reactrouter.com/web/api/Hooks/useparams
