Components not re-rendering on route change - React HashRouter - javascript

I've got a problem with react and react-router.
When I click on a link (in my example contact in Footer.js), the url changes, but the desired component Location is not shown. When I refresh the site then, the correct component is displayed.
App.js:
import React, { Component } from 'react';
import { BrowserRouter as Router, HashRouter, Route, Link } from 'react-router-dom';
import 'bootstrap/dist/css/bootstrap.css';

What I'm doing wrong? Why it is not working, when I click on a link?

Got it working now.
I needed to change <HashRouter> to <Router>. Then it works fine.
UPDATE:
This solution solves the problem, but then there is a different problem: When I have navigated and refresh the page, then an error (404) is thrown, because there is of course no such a page on the server.
I need to get the HashRouter work.

When you declare your routes in App.js, you should pass the props to the component:
components: props => <Location {...props} <insert other props> />
You should stick to the <Router> solution as having unnecessary hash in the url is ugly.
When I have navigated and refresh the page, then an error (404) is thrown, because there is of course no such a page on the server.
To resolve this, you need to set up a redirect to redirect all requests to the base url for the React app to handle (the url displayed will be preserved).
On Netlify, you can create a _redirects file in your public folder with the content:
/* /index.html 200
On AWS S3, the redirect rules can be set in S3 or CloudFront, see the answers here.
For Google Cloud bucket, see this.
For Github pages, see this.

In your Route component you use component prop to pass the Location component (instead of render or children props available on Route) the router uses React.createElement to create a new React element from the given component. That means if you provide an inline function to the component prop, you would create a new component every render. This results in the existing component unmounting and the new component mounting instead of just updating the existing component. When using an inline function for inline rendering, use the render or the children prop.However in your case it seems you are using it for no reason so you should just pass the component and not an inline function that returns it like so :
const routes = [
{
path: '/',
exact: true,
components: <Home key="home" currentLanguage={this.state.currentLanguage}/>
},
{
path: '/contact',
exact: true,
components: <Location key="locations" currentLanguage={this.state.currentLanguage} country={this.state.countryObject} contacts= {this.state.contacts} onCountryChange={this.handleCountryChange.bind(this)} />
},
]

Make your routes use Component as below
import {IndexRoute, Route} from 'react-router';
<Route component={App}>
<Route path='/locations' component={LocationComponent}/>
</Route>
This is what I am doing in my current project without using HashRouter.
Currently, When you do
<Route key={index} path={route.path} exact={route.exact} component={route.components} />
I don't think {route.components} treats it as a component.

Could be a problem with withRouter().

How to pass props from from parent to grand child when using react-router--dom <Link>?

I sending image path data from parent component(TaskSubmissions.js component) to child component(Card.js component) and same image path data I want to pass child component of Card which is CardDetail.js.
Problem is data is passed from TaskSubmissions.js to Card.js but it's not getting passed from Card.js to DetailCard.js
I am using react-router-dom . To understand it better below I am sharing all three components code. I'll appreciate your help.
P.S I am new to react and trying to understand the flow with such experiments.
Data Flow = image URL is passing from TaskSubmission.js to -> Card.js to -> DetailCard.js
Parent Component TaskSubmissions.js
import React from "react";
import Card from "../components/Card";
const TaskSubmissions = () => {
return (
<div className="container-fluid">
<div className="row justify-content-center mt-5">
<h1 className="text-info display-4 text-center">
Review All Students Task!
</h1>
</div>
<div className="row justify-content-center">
<p className="lead text-center">Rate your students performance</p>
</div>
<div className="row justify-content-center mt-5">
<div className="col-lg-3 col-md-4 col-sm-12">
<Card
name="Jane"
path="https://source.unsplash.com/aob0ukAYfuI/400x300"
/>
</div>
</div>
</div>
);
};
export default TaskSubmissions;
Child Component Card.js
import React from "react";
import { Link } from "react-router-dom";
const Card = (props) => {
return (
<div className="container-fluid">
<div className="row">
<h4 className="card-title">{props.name}</h4>
<Link
to={{
pathname: "/detail",
state: { imgpath: props.path, name: props.name },
}}
className="d-block mb-4 h-100"
>
<img
className="img-fluid img-thumbnail"
src={props.path}
alt="image"
/>
</Link>
</div>
</div>
);
};
export default Card;
GrandChild Component CardDetail.js
import React from "react";
import { useLocation } from "react-router";
const CardDetail = (props) => {
const data = useLocation();
return (
<div className="container-fluid">
<div className="row justify-content-center">
<div className="card mb-3">
<img src={data.imgpath} className="card-img-top" alt="..." />
<div className="card-body">
<h5 className="card-title">{data.name}</h5>
<p className="card-text">Assignment 1 is completed.</p>
<p className="card-text">
<small className="text-muted">Last updated 3 mins ago</small>
</p>
</div>
</div>
</div>
</div>
);
};
export default CardDetail;
Try accessing it differently. You are currently doing const data = useLocation(); and then data.imgpath. Have you tried console.log(data)?
I would suggest the following change:
<img src={data.state.imgpath} className="card-img-top" alt="..."/>
<h5 className="card-title">{data.state.name}</h5>
Since you've stored it in
{{pathname: "/detail", state: {imgpath: props.path, name: props.name}}}
So it is held in data.state.
data Object should look something like this:
{
...
pathname: '/detail',
state: {
name: 'bar',
imgpath: 'foo'
}
}

How can I use nested routes with props for a child component

I'm building an react app where I have a feed component and the feed component consists of array of post components. The post component contains a link in it for viewing the full post component. I'm not able to pass the respective props to the full post component. I'm not able to do a nested route for the fullpost component.
this is my layout component
import React, { Component } from "react";
import Header from "../Header/Header";
import classes from "./Layout.css";
import { Route, Switch } from "react-router-dom";

state = {
users: [],

this.setState({ users: response.data });

how to show specific post details by clicking using react-router-parameters?

I'm using map to view all posts using axios. And I just want show when I click a specific post to see more information. I'm using react parameters. But it's not working.
Here is my one component
import React, {Component} from 'react';
import Album from './album'
import {Link, BrowserRouter as Router, Route} from 'react-router-dom'
import axios from "axios"
class ViewDataAPI extends Component{
state = {
posts: []
}
componentDidMount(){
axios.get('https://jsonplaceholder.typicode.com/comments')
.then(response => {
this.setState({
posts: response.data
})
})
.catch(error => console.log('error'))
}
render(){
let { posts } = this.state
if(posts.length === 0){
return <h1>Loading...</h1>
}
else{
return(
<Router>
<div className="header">
<div className="container">
<div className="row">
<div className="col-lg-12 col-sm-12 col-xs-12">
<div className="text-center mb-20">
<h1>View Data From API</h1>
<p>using jsx-component, props, state, map in react </p>
</div>
</div>
</div>
<div className="row">
{
posts.map(post =>
{
return (
<Album
key={post.id}
name={post.name}
email = {post.email}
body = {post.body}
view = {post.id}
/>
)
}
)
}
</div>
{/* here is im using params, and to match by clicking specific id to show/view more information */}
<div className="row">
{posts && (
<Route path="/album/:albumId"
render = {({match}) => (
<ViewPosts {...posts.find(pv => pv.id === match.params.albumId)} />
)}
/>
)}
</div>
</div>
</div>
</Router>
)
}
}
}
export default ViewDataAPI;
// This component using for show details
const ViewPosts = ({posts}) =>{
return(
<div className="col-lg-6">
<div className="card border-dark mb-3">
<div className="card-body text-dark">
<div className="album">
<h3>{posts.name}</h3>
<h3>{posts.email}</h3>
<Link to="./">Back To Home</Link>
</div>
</div>
</div>
</div>
);
}
This is album component that has a link
import React, {Component} from 'react'
import {Link} from "react-router-dom"
class Album extends Component{
render(){
return(
<div className="col-lg-6">
<div className="card border-dark mb-3">
<div className="card-body text-dark">
<div className="album">
<h3>{this.props.name}</h3>
<p>{this.props.email}</p>
<p>{this.props.body}</p>
<Link to={`/album/${this.props.view}`}>View</Link>
</div>
</div>
</div>
</div>
);
}
}
export default Album;
https://react-pin.netlify.com/
Please follow the above link to what I'm trying to do. Please first go to one "View Data From API"
My github link https://github.com/sultan0/reactpin
The route param is a string. There is no implicit type conversion
with === Operator. Therefore you have to do it explicitly. Pls. see
Comparison operators for a further explanation.
The spread ... Operator is misplaced here.
The solution is:
<ViewPosts posts={posts.find(pv => pv.id === parseInt(match.params.albumId))} />
Update
You would like to use the Switch component from react router:
Switch is unique in that it renders a route exclusively. In contrast, every Route that matches the location renders inclusively.
Pls refer to react router documentation.
I created a pull request as an example. Hope it helps.

React Redirect when clicking button

I´m learning in react and practicing making a simple application to login and view messages sent.
I´ve read a lot about routing, links and redirect, but i couldn´t translate to my app.
I Would like to click in the "Login" button of a component and redirect to another component.
Here i have the principal component : App.js
import React, { Component } from 'react';
import { BrowserRouter as Router, Route, Link, Switch } from 'react-router-dom';
class Login extends Component {
state = {
loggedIn:false
};
loginHandle = () => {
this.setState({loggedIn:true});
}
render(){
return (
<div className="container d-flex h-100">
<div className="row align-self-center w-100">
<div className="col-6 mx-auto">
<div className="jumbotron">
<form name="form1">
<fieldset>
<legend>Chat App</legend>
<label for="UserName" className="col-form-label">Username</label>
<input type="text" className="form-control col-12" id="UserName"></input>
<label for="Password" className="col-form-label">Password</label>
<input type="text" className="form-control col-12" id="Password"></input>
<button type="button" value="log in" className="btn btn-secondary" onClick={this.loginHandle}>Login</button>
</fieldset>
</form>
<div style={{float:"right"}}>
<div className="login-help ">
Register - Forgot Password
</div>
</div>
</div>
</div>
</div>
</div>
);
}
}
export default Login;
I wrapped all the Links in a Navigation component
So, when i route /, it goes to the Login component
class Login extends Component {
state = {
loggedIn:false
};
loginHandle = () => {
this.setState({loggedIn:true});
}
render(){
return (
<div className="container d-flex h-100">
<div className="row align-self-center w-100">
<div className="col-6 mx-auto">
<div className="jumbotron">
<form name="form1">
<fieldset>
<legend>Chat App</legend>
<label for="UserName" className="col-form-label">Username</label>
<input type="text" className="form-control col-12" id="UserName"></input>
<label for="Password" className="col-form-label">Password</label>
<input type="text" className="form-control col-12" id="Password"></input>
<button type="button" value="log in" className="btn btn-secondary" onClick={this.loginHandle}>Login</button>
</fieldset>
</form>
<div style={{float:"right"}}>
<div className="login-help ">
Register - Forgot Password
</div>
</div>
</div>
</div>
</div>
</div>
);
}
}
export default Login;
Do i have to import routes and redirect in the Login component, or i have to mange all from the App component?
Sorry about this mess, but i don´t know how to continue
Thanks a lot. I really apreciatted in advance.
The simplest way for navigating to another route.
For example you can wrap your Forgot password like following:
<Link to="/forgotRoute">Forgot password?</Link>
Don't forget to add /forgotRoute handling into your Navigator config (where you routed / to your Login component).
Hope it helps.
The correct way for what you want i think it is. So follow me..
You need to use router. In my case i'm using react-router-dom.
First router App component, by default page its renders DefaultPage components and in DefaultPage when component mounted you can render client anywhere.
index.js looks like:
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import { Route, Switch } from 'react-router-dom';
class DefaultPage extends Component {
state = {
autorized: false,
mounted: false,
}
componentDidMount = () => {
const { autorized } = this.state;
if (!autorized) {
this.props.history.push('/login');
return;
}
this.setState({
mounted: true,
});
}
render = () => {
if (!this.state.mounted) {
return (
<React.Fragment>
<p>Waiting...</p>
</React.Fragment>
)
}
return (
<React.Fragment>
<p>Hello...</p>

Why does the twitter widget not re-render reactjs

I am using the twitter embedded timeline on my application to show the twitter feed of a companies twitter account.
When I get a result from an API, the state changes to the correct values, but the twitter widget does not appear to change
TwitterCard.js
import React from "react";
export class TwitterCard extends React.Component{
render() {
return (
<a className="twitter-timeline" href={this.props.href} data-height="100%">Tweets by {this.props.ticker}</a>
)
}
}
I have attached screenshots of the react plugin output for proof of state change.
The parent class is rather large, so I have posted the render method:
render() {
return (
<div>
<NavBar/>
<div className="container-fluid">
<div className="row">
<NavBarSide clickHandler={(url) => this.handleNavClick(url)}/>
<Dashboard
errorChart={this.state.errorChart}
twitter={this.state.twitter}
status={this.state.status}
/>
</div>
</div>
</div>
)
}
The parent passes these values to the Dashboard:
import React from "react";
import { Switch, Route } from 'react-router-dom';
import { Chart } from "./Chart";
import { TwitterCard } from "./TwitterCard";
export class Dashboard extends React.Component {
render() {
return (
<div className="col-md-9 ml-sm-auto col-lg-10 pt-2 px-3">
<div className="row">
<div className="col-lg-8">
<div className="row">
<div className="col-lg-6">
<div className="card border-0">
<div className="card-body">
<Chart chart={this.props.errorChart}/>
</div>
</div>
</div>
</div>
</div>
<div className="col-lg-4">
<TwitterCard href={this.props.twitter} ticker={this.props.ticker}/>
</div>
</div>
</div>
)
}
}
You can force an update to the twitter component when the ticket changes by keying it with the ticker where you render it in your dashboard component:
<TwitterCard
key={this.props.ticker}
href={this.props.twitter}
ticker={this.props.ticker}
/>
