useParams for category products - css

I am new with React JS and I am trying to be able to call the list of products by their category. That should be done from the Navbar, but I could not sort it out. If there is someone to help me with it I would much appreciate it. Below is the code.
this is my route page
const Pages = () => {
return (
<Routes>
<Route path="/" element={<Home />}/>
<Route path="/products/:_type" element={<Products />}/>
</Routes>
)
}
this one is for fetching products
let params = useParams()
const[shopProducts,setShopProducts] = useState([])
const[ifFetch,setIfFetch] = useState(false)
const getProducts = async (name) =>{
const query = `*[_type ==${name}]`
await client.fetch(query).then((res) => {
//console.log(res)
setShopProducts(res)
console.log(shopProducts)
setIfFetch(true)
})
}
useEffect(()=>{
getProducts(params.type)
},[params.type,ifFetch])
and this is my link from navbar
<NavLink to={'/products/men'}>Men</NavLink>

Route page
const Pages = () => {
return (
<Routes>
<Route path="/" element={<Home />}/>
<Route path="products/:type" element={<Products />}/>
</Routes>
)
}
And get route parameter like this way -
let { type } = useParams()
const[shopProducts,setShopProducts] = useState([])
const[ifFetch,setIfFetch] = useState(false)
useEffect(()=> {
client.fetch(`https://ho4y55im.api.sanity.io/v2021-10-21/data/production?query=${type}`)
.then((res)=> {
setShopProducts(res)
setIfFetch(true)
}
},[type, ifFetch])

How to enable ssg/ssr in next.js with custom App component

I have a custom _app.js which looks like this:
function MyApp({ Component, pageProps }) {
const Layout = Component.layoutProps?.Layout || React.Fragment
const layoutProps = Component.layoutProps?.Layout
? { layoutProps: Component.layoutProps }
: {}
const meta = Component.layoutProps?.meta || {}
const description =
meta.metaDescription || meta.description || 'Meta Description'
const store = useStore(pageProps.initialReduxState)
return (
<QueryClientProvider client={queryClient}>
<Provider session={pageProps.session}>
<Title suffix="My Dynamic Site">{meta.metaTitle || meta.title}</Title>
<Description>{description}</Description>
<Meta />
<ReduxProvider store={store}>
<PersistGate persistor={store.__PERSISTOR} loading={null}>
<CartBox />
<Layout {...layoutProps}>
<Component {...pageProps} />
</Layout>
</PersistGate>
</ReduxProvider>
<ReactQueryDevtools initialIsOpen={false} />
</Provider>
</QueryClientProvider>
)
}
MyApp.getInitialProps = async (appContext) => {
// calls page's `getInitialProps` and fills `appProps.pageProps`
const appProps = await App.getInitialProps(appContext);
return { ...appProps }
}
export default MyApp
Now, I would like to fetch data using ssg/ssr data fetching method to help SEO team for my page components.
But, it seems any of the methods aren't working as expected, none of them actually passing props to the page component.
Here's my page component.
const HomePage = ({ title, stars }) => {
console.log(title, stars); // undefined, undefined
return (
<div>
<Header title={title} />
<GhStars stars={stars} />
<Footer />
</div>
)
}
export const getStaticProps = async () => {
return {
props: {
title: "My Dynamic Title From getStaticProps"
}
}
}
// I tried both getInitialProps & getStaticProps independently.
HomePage.getInitialProps = async (ctx) => {
const res = await fetch('https://api.github.com/repos/vercel/next.js')
const json = await res.json()
return { stars: json.stargazers_count }
}
export default HomePage
I might be missing something for sure, which I failed to figure out so far.
Any help will be really much appreciated. Thanks.

React - Fetch in useEffect to check user database

I'm stuck trying to find the best way to do a user search in the database and if there is mount the page, if there is no redirect to the root. This is the last thing I tried, but always redirect to root.
App.js
function App() {
return (
<div className="container">
<Suspense fallback={<div></div>}>
<Switch>
<Route exact path="/" render={() => <Home />} />
<Route path="/login" render={() => <Login />} />
<Route path="/register" render={() => <Register />} />
<Route path="/resetpassword" render={() => <ResetPassword />} />
<Route path="/:username">
<Middleware />
</Route>
<Route render={() => <Home />} />
</Switch>
</Suspense>
</div>
);
}
Middleware.js
const Middleware = () => {
const [exist, setExist] = useState(false);
const { username } = useParams()
useEffect(() => {
var isCancelled = false;
async function fetch() {
await datosFirebaseUsuario(username)
.then((data) => {
if (data) {
if (!isCancelled) {
setExist(true)
}
}
});
}
fetch();
return () => {isCancelled = true}
}, [username])
if (!exist) {
return <Redirect to="/" />
}
return (
<>
<Header />
<Links />
<Footer />
</>
)
}

How to integrate React Router in Meteor?

I am trying to integrate Routes using React Router in Meteor Project. I have followed the Meteor React documentation but somehow its not working. Have tried with "Router" instead of "BrowserRouter" but no luck. Any suggestions on this.
imports/startup/client/routes.js
import { BrowserRouter, Route, Switch } from "react-router-dom";
import App, City , NotFound from "respective-modules";
export const renderRoutes = () => {
<BrowserRouter>
<div>
<Switch>
<Route exact path="/" component={App} />
<Route exact path="/city" component={City} />
<Route component={NotFound} />
</Switch>
</div>
</BrowserRouter>;
client/main.html
<body>
<div id="react-target"></div>
</body>
client/main.jsx
import { renderRoutes } from "/imports/startup/client/routes.js";
Meteor.startup(() => {
render(renderRoutes(), document.getElementById("react-target"));
});
But a blank page is getting appeared.
If the code you are showing is correct (i.e., copied accurate from what you are running), then you just have an extra curly bracket:
export const renderRoutes = () => {
<BrowserRouter>
needs to be either:
export const renderRoutes = () =>
<BrowserRouter>
or
export const renderRoutes = () => {
return <BrowserRouter>

Implement breadcrumbs with react, react-router and redux

I had designed the action and reducer in below:
// Action Types
const PUSH_BREADCRUMB = 'PUSH_BREADCRUMB';
const POP_BREADCRUMB = 'POP_BREADCRUMB';
// ActionCreator
const pushBreadcrumb = (payload: { text, link }) => ({
type: PUSH_BREADCRUMB,
payload
});
const popBreadcrumb = () => ({ type: PUSH_BREADCRUMB });
// Reducer
const initState = [
{ text: 'Home', link: '/' }
];
const breadcumbsReducer = (state = initState, action) => {
switch (action.type) {
case PUSH_BREADCRUMB:
return [...state, action.payload];
case POP_BREADCRUMB:
return state.slice(0, state.length - 1);
default:
return state
};
};
Below is my component and router:
//...import some components
// ...connect and map breadcrumbs
const Header = ({ breadcrumbs }) => {
return (
<ul>
{breadcrumbs.map({ item, link } =>
<li key={link}><Link to={link}>{text}</Link></li>
)}
</ul>
);
};
ReactDOM.render(
<Provider>
<Router>
<AppContainer>
<Header />
<Route exact path='/orders' component={OrderListContainer} />
<Route path='/orders/:id' component={OrderDetailContainer} />
</AppContainer>
</Router>
</Provider>,
document.getElementById('root')
);
Then:
Dispatch pushBreadcrumb in OrderListContainer#componenetWillMount and OrderDetailContainer#componenetWillMount
Dispatch popBreadcrumb in OrderListContainer#componentWillUnmount and OrderDetailContainer#componentWillUnmount.
The excepted breadcrumbs is Home > Orders > Detail;
But when i stay in /orders/:id and refresh page, it will be Home > Detail.
Is there better way to implement breadcrumbs with redux?
That happens because state is reset after you refresh. You can try to implement your solution with persistent store - this will keep selected state keys to browser localStorage.

How to set up Google Analytics for React-Router?

I'm trying set up Google Analytics on my react site, and have come across a few packages, but none of which has the kind of set up that I have in terms of examples. Was hoping someone could shed some light on this.
The package I'm looking at is, react-ga.
My render method on my index.js looks like this.
React.render((
<Router history={createBrowserHistory()}>
<Route path="/" component={App}>
<IndexRoute component={Home} onLeave={closeHeader}/>
<Route path="/about" component={About} onLeave={closeHeader}/>
<Route path="/gallery" component={Gallery} onLeave={closeHeader}/>
<Route path="/contact-us" component={Contact} onLeave={closeHeader}>
<Route path="/contact-us/:service" component={Contact} onLeave={closeHeader}/>
</Route>
<Route path="/privacy-policy" component={PrivacyPolicy} onLeave={closeHeader} />
<Route path="/feedback" component={Feedback} onLeave={closeHeader} />
</Route>
<Route path="*" component={NoMatch} onLeave={closeHeader}/>
</Router>), document.getElementById('root'));
Keep a reference to your history object. i.e.
import { createBrowserHistory } from 'history';
var history = createBrowserHistory();
ReactDOM.render((
<Router history={history}>
[...]
Then add a listener to record each pageview. (This assumes you've already set up the window.ga object in the usual manner.)
history.listen((location) => {
window.ga('set', 'page', location.pathname + location.search);
window.ga('send', 'pageview');
});
The question is about react-ga but this package will soon be obsolete because it doesn't support Google Analytics 4. Below is a generic solution that works with any library or native gtag. For adding GA4 to React check out this answer: https://stackoverflow.com/a/73354959/2771889.
Since react-router v5.1.0 this can be solved a lot easier with useLocation.
usePageTracking.js
import { useEffect } from "react";
import { useLocation } from "react-router-dom";
const usePageTracking = () => {
const location = useLocation();
useEffect(() => {
// track pageview with gtag / react-ga / react-ga4, for example:
window.gtag("event", "page_view", {
page_path: location.pathname + location.search,
});
}, [location]);
};
export default usePageTracking;
App.js
const App = () => {
usePageTracking();
return (...);
};
Keep in mind that Google Analytics does automatic page tracking, but this will not work for every use case. For example, hash and search parameter changes are not tracked. This can lead to a lot of confusion. For example, when using HashRouter or anchor links the navigation will not be tracked. To have full control over page view tracking you can disable automatic tracking. See for a detailed explanation: The Ultimate Guide to Google Analytics (UA & GA4) on React (Or Anything Else
You can see this working in cra-typescript-starter where I'm using it with GA4.
Given that google analytics is loaded and initialised with a tracking id.
Here is a solution for react-router version 4 using the <Route> component to track page views.
<Route path="/" render={({location}) => {
if (typeof window.ga === 'function') {
window.ga('set', 'page', location.pathname + location.search);
window.ga('send', 'pageview');
}
return null;
}} />
You simply render this component inside the <Router> (but not as a direct child of a <Switch>).
What happens is that whenever the location prop changes it causes a re-render of this component (not actually rendering anything) that fire a pageview.
I'm using React Router v4 and the Google Analytics Global Site Tag, which appears to be recommended at the time of writing this.
And here's my solution:
Create a component wrapped in withRouter from react-router-dom:
import React from 'react';
import { withRouter } from 'react-router-dom';
import { GA_TRACKING_ID } from '../config';
class GoogleAnalytics extends React.Component {
componentWillUpdate ({ location, history }) {
const gtag = window.gtag;
if (location.pathname === this.props.location.pathname) {
// don't log identical link clicks (nav links likely)
return;
}
if (history.action === 'PUSH' &&
typeof(gtag) === 'function') {
gtag('config', GA_TRACKING_ID, {
'page_title': document.title,
'page_location': window.location.href,
'page_path': location.pathname
});
}
}
render () {
return null;
}
}
export default withRouter(GoogleAnalytics);
Simply add the component within your router (I believe ideally after any routes that would be matched and any Switch components, because the analytics function should not be priority over your site rendering):
import React from 'react';
import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';
import IndexPage from './IndexPage';
import NotFoundPage from './NotFoundPage';
import GoogleAnalytics from './GoogleAnalytics';
const App = () => (
<Router>
<Switch>
<Route exact path="/" component={IndexPage} />
<Route component={NotFoundPage} />
</Switch>
<GoogleAnalytics />
</Router>
);
As stated:
withRouter will re-render its component every time the route changes with the
same props as render props
So when the route changes, the GoogleAnalytics component will update, it will receive the new location as props, and history.action will be either PUSH for a new history item or POP to signal going backwards through the history (which I think shouldn't trigger a page view, but you can adjust the if statements in componentWillUpdate as you see fit (you could even try componentDidUpdate with this.props instead, but I'm unsure which is better)).
Note if you're using the react-router-dom package from react-router-4 you can handle this like so:
import { Router, Route } from 'react-router-dom';
import { createBrowserHistory } from 'history';
const history = createBrowserHistory();
const initGA = (history) => {
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','https://www.google-analytics.com/analytics.js','ga');
ga('create', 'YOUR_IDENTIFIER_HERE', 'auto');
ga('send', 'pageview');
history.listen((location) => {
console.log("tracking page view: " + location.pathname);
ga('send', 'pageview', location.pathname);
});
};
initGA(history);
class App extends Component { //eslint-disable-line
render() {
return
(<Router history={history} >
<Route exact path="/x" component={x} />
<Route exact path="/y" component={y} />
</Router>)
}
}
Note that this requires you to install the history package (npm install history). This is already a dependency of react-router-dom so you're not adding any page weight here.
Also note: It is not possible to use the BrowserRouter component AND instrument your ga tracking this way. This is okay because the BrowserRouter component is just a really thin wrapper around the Router object. We recreate the BrowserRouter functionality here with <Router history={history}> where const history = createBrowserHistory();.
I would suggest using the excellent react-router-ga package that is extremely lightweight and easy to configure, especially when using the BrowserRouter wrapper.
Import the component:
import Analytics from 'react-router-ga';
Then simply add the <Analytics> within your BrowserRouter:
<BrowserRouter>
<Analytics id="UA-ANALYTICS-1">
<Switch>
<Route path="/somewhere" component={SomeComponent}/>
</Switch>
</Analytics>
</BrowserRouter>
I like how Mark Thomas Müller suggests here:
In your index.js
import ReactGA from 'react-ga'
ReactGA.initialize('YourAnalyticsID')
ReactDOM.render(<App />, document.getElementById('root'))
Where your routes are:
import React, { Component } from 'react'
import { Router, Route } from 'react-router-dom'
import createHistory from 'history/createBrowserHistory'
import ReactGA from 'react-ga'
const history = createHistory()
history.listen(location => {
ReactGA.set({ page: location.pathname })
ReactGA.pageview(location.pathname)
})
export default class AppRoutes extends Component {
componentDidMount() {
ReactGA.pageview(window.location.pathname)
}
render() {
return (
<Router history={history}>
<div>
<Route path="/your" component={Your} />
<Route path="/pages" component={Pages} />
<Route path="/here" component={Here} />
</div>
</Router>
)
}
}
Short, scalable and simple :)
Always go with the library's recommended way
In the React-GA documentation, they have added a community component recommended for using with React Router: https://github.com/react-ga/react-ga/wiki/React-Router-v4-withTracker
Implementation
import withTracker from './withTracker';
ReactDOM.render(
<Provider store={store}>
<ConnectedRouter history={history}>
<Route component={withTracker(App, { /* additional attributes */ } )} />
</ConnectedRouter>
</Provider>,
document.getElementById('root'),
);
Code
import React, { Component, } from "react";
import GoogleAnalytics from "react-ga";
GoogleAnalytics.initialize("UA-0000000-0");
const withTracker = (WrappedComponent, options = {}) => {
const trackPage = page => {
GoogleAnalytics.set({
page,
...options,
});
GoogleAnalytics.pageview(page);
};
// eslint-disable-next-line
const HOC = class extends Component {
componentDidMount() {
// eslint-disable-next-line
const page = this.props.location.pathname + this.props.location.search;
trackPage(page);
}
componentDidUpdate(prevProps) {
const currentPage =
prevProps.location.pathname + prevProps.location.search;
const nextPage =
this.props.location.pathname + this.props.location.search;
if (currentPage !== nextPage) {
trackPage(nextPage);
}
}
render() {
return <WrappedComponent {...this.props} />;
}
};
return HOC;
};
export default withTracker;
here is a simplest way to track all paths with some work arounds:
npm i --save history react-ga
create a file history.js
import { createBrowserHistory } from "history"
import ReactGA from "react-ga"
ReactGA.initialize(process.env.REACT_APP_GA)
const history = createBrowserHistory()
history.listen((location) => {
ReactGA.pageview(location.pathname)
})
// workaround for initial visit
if (window.performance && (performance.navigation.type === performance.navigation.TYPE_NAVIGATE)) {
ReactGA.pageview("/")
}
export default history
and then import it to where is set your Router
import history from "./history"
...
class Route extends Component {
render() {
return (
<Router history={history}>
<Switch>
<Route path="/" exact component={HomePage} />
...
</Switch>
</Router>
)
}
export default Route

First, in your index.js set onUpdate function to call ga
import ga from 'ga.js';
onUpdate() {
console.log('=====GA=====>', location.pathname);
console.log('=====GA_TRACKING_CODE=====>', GA_TRACKING_CODE);
ga("send", "pageview", location.pathname);
}
render() {
return (
<Router onUpdate={this.onUpdate.bind(this)}>...</Router>
);
}
And ga.js:
'use strict';
if(typeof window !== 'undefined' && typeof GA_TRACKING_CODE !== 'undefined') {
(function(window, document, script, url, r, tag, firstScriptTag) {
window['GoogleAnalyticsObject']=r;
window[r] = window[r] || function() {
(window[r].q = window[r].q || []).push(arguments)
};
window[r].l = 1*new Date();
tag = document.createElement(script),
firstScriptTag = document.getElementsByTagName(script)[0];
tag.async = 1;
tag.src = url;
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
})(
window,
document,
'script',
'//www.google-analytics.com/analytics.js',
'ga'
);
var ga = window.ga;
ga('create', GA_TRACKING_CODE, 'auto');
module.exports = function() {
return window.ga.apply(window.ga, arguments);
};
} else {
module.exports = function() {console.log(arguments)};
}
I suggest using the Segment analytics library and following the React quickstart guide to track page calls using the react-router library. You can allow the <Route /> component to handle when the page renders and use componentDidMount to invoke page calls. The example below shows one way you could do this:
const App = () => (
<div>
<Switch>
<Route exact path="/" component={Home} />
<Route path="/about" component={About} />
</Switch>
</div>
);
export default App;
export default class Home extends Component {
componentDidMount() {
window.analytics.page('Home');
}
render() {
return (
<h1>
Home page.
</h1>
);
}
}
I’m the maintainer of https://github.com/segmentio/analytics-react. With Segment, you’ll be able to switch different destinations on-and-off by the flip of a switch if you are interested in trying multiple analytics tools (we support over 250+ destinations) without having to write any additional code. 🙂
If you use hash or browser history you can do:
import trackingHit from 'tracking';
import { Router, browserHistory } from 'react-router';
browserHistory.listen(trackingHit);
// OR
import { Router, hashHistory } from 'react-router';
hashHistory.listen(trackingHit);
where ./tracking.es6
export default function(location) {
console.log('New page hit', location.pathname);
// Do your shizzle here
}
basic react-ga implementation with your index.js
var ReactGA = require('react-ga'); // require the react-ga module
ReactGA.initialize('Your-UA-ID-HERE'); // add your UA code
function logPageView() { // add this function to your component
ReactGA.set({ page: window.location.pathname + window.location.search });
ReactGA.pageview(window.location.pathname + window.location.search);
}
React.render((
<Router history={createBrowserHistory()} onUpdate={logPageView} > // insert onUpdate props here
<Route path="/" component={App}>
<IndexRoute component={Home} onLeave={closeHeader}/>
<Route path="/about" component={About} onLeave={closeHeader}/>
<Route path="/gallery" component={Gallery} onLeave={closeHeader}/>
<Route path="/contact-us" component={Contact} onLeave={closeHeader}>
<Route path="/contact-us/:service" component={Contact} onLeave={closeHeader}/>
</Route>
<Route path="/privacy-policy" component={PrivacyPolicy} onLeave={closeHeader} />
<Route path="/feedback" component={Feedback} onLeave={closeHeader} />
</Route>
<Route path="*" component={NoMatch} onLeave={closeHeader} />
</Router>), document.getElementById('root'));
Based on #david-l-walsh and #bozdoz suggestions
I created a HOC that execute the window.ga('set','page','{currentUrl}) and window.ga('send', 'pageview'); function and is easly used directly in the router page...
this is the HOC:
import React from 'react';
import { history } from '../../store'; // or wherever you createBrowserHistory(); invokation is
function withGAHistoryTrack(WrappedComponent) {
return class extends React.Component {
constructor(props) {
super(props);
}
componentDidMount() {
const { location } = history;
const page = location.pathname + location.search;
if (typeof window.ga === 'function') {
window.ga('set', 'page', page);
window.ga('send', 'pageview');
}
}
render() {
return <WrappedComponent {...this.props} />;
}
};
}
export default withGAHistoryTrack;
and is used this way in the router page:
<Route
path={'yourPath'}
component={withGAHistoryTrack(yourComponent)}
exact
/>
For dynamically updating url on some event (like onClick etc), following can be used:
//Imports
import ReactGA from "react-ga";
import { createBrowserHistory } from "history";
// Add following on some event, like onClick (depends on your requirement)
const history = createBrowserHistory();
ReactGA.initialize("<Your-UA-ID-HERE>");
ReactGA.pageview(history.location.pathname);
