I am migrating from my Create React App (client-side-rendering) to Next JS (server-side rendering) due to SEO reasons. Migrating was going well until using React-Redux-Firebase / Firestore. This is the page I am trying to load:
Discover.js
import React, { Component } from 'react'
import { firestoreConnect, isEmpty } from 'react-redux-firebase';
import { compose } from 'redux'
import { connect } from "react-redux";
import { blogpostsQuery } from '../blogposts/blogpostsQuery';
import DiscoverList from "./DiscoverList";
const mapState = (state, ownProps) => {
let blogposts = {};
blogposts =
!isEmpty(state.firestore.ordered.blogposts) &&
state.firestore.ordered.blogposts;
return {
blogposts,
};
};
class DiscoverPage extends Component {
render() {
const {blogposts} = this.props
return (
<div className="container">
<div className="hero">
<h1>Discover stories</h1>
<p className="lead">Blogpost published:</p>
</div>
<DiscoverList blogposts={blogposts} />
</div>
)
}
}
export default compose(
firestoreConnect(() => blogpostsQuery()),
connect(mapState, null)
)(DiscoverPage)
The error I received is this:
ReferenceError: XMLHttpRequest is not defined

error Command failed with exit code 1.
I wasn't the only one with this problem and I have found the solution on GitHub by prescottprue:
https://github.com/prescottprue/react-redux-firebase/issues/72
Including documentation: http://react-redux-firebase.com/docs/recipes/ssr.html
// needed to fix "Error: The XMLHttpRequest compatibility library was not found."
global.XMLHttpRequest = require('xmlhttprequest').XMLHttpRequest
The problem is (sorry i am new developer) I have no idea where to add this line of code? Adding it to _app.js doesnt work.. i've added https://www.npmjs.com/package/xmlhttprequest but still no luck...
-app.js
import App from "next/app";
import { Provider } from "react-redux";
import React, { Fragment } from "react";
import withRedux from "next-redux-wrapper";
import "../src/styles.css";
import configureStore from "../src/app/store/configureStore";
import Header from "../src/app/layout/Header";
import NavBar from "../src/app/layout/nav/Navbar/NavBar";
import Footer from "../src/app/layout/Footer";
global.XMLHttpRequest = require('xmlhttprequest').XMLHttpRequest
class MyApp extends App {
static async getInitialProps({ Component, ctx }) {
const pageProps = Component.getInitialProps
? await Component.getInitialProps(ctx)
: {};
//Anything returned here can be accessed by the client
return { pageProps: pageProps };
}
render() {
const { Component, pageProps, store } = this.props;
return (
<Fragment>
<Header />
<NavBar />
<Provider store={store}>
<Component {...pageProps} />
</Provider>
<Footer />
</Fragment>
);
}
}
export default withRedux(configureStore)(MyApp);
Could somebody help me?
Many thanks

The point is to implement a dynamic SSR component can be re-rendered by a search input.
I solved this by creating a layout.tsx file on my specific router then import children which made me dynamic render ssr component by the client component:
Layout.tsx
import React, { Suspense } from "react";
import Search from "./Search";
export default function RootLayout({
children,
}: {
children: React.ReactNode;
}) {
return (
<div className="layout">
<Search />
{children}
</div>
);
}
Search.tsx
"use client";
import { FormEvent, useState } from "react";
import { useRouter } from "next/navigation";
export default function Search() {
const [text, setText] = useState<string>("")
const router: any = useRouter();
const handleSubmit = (e: FormEvent<HTMLFormElement>) => {
e.preventDefault();
setText('')
router.push(`/definition/${text}`)
}
return (
<form onSubmit={handleSubmit} className='search'>
<input onChange={(e) => setText(e.target.value)}
value={text} type="text"
placeholder={"write to search"} />
</form>
);
} );
}
Need One Help i am trying to call api in nextjs using
redux(Here,SSR is not possible)
and getServerSideProps(Here, SSR is Possible but without redux) in both case API Called Successfully. If i used it individually bot are working well but now i want to merge it both and i have read about next-redux-wrapper but when i am integrate it.

Try to Use Next-redux-wrapper but not able to find solution regarding that

import { Provider } from "react-redux";
import store, { wrapper } from "../redux/store";
import "../styles/globals.css";
function MyApp({ Component, pageProps }) {
return (

</Provider>
</>
);
}
export default wrapper.withRedux(MyApp);

legacy_createStore,
} from "redux";

In Nextjs, I would like to avoid importing Apollo lib and ApolloProvider on specific paths such as the homepage since the bundle is huge.
Here is how I tried to proceed without success (it's always bundled):
import { ApolloProvider } from "#apollo/client";
import type { NextPageWithLayout } from "next";
import type { AppProps } from "next/app";
import { useApollo } from "#/libraries/apollo/client";
type AppPropsWithLayout = AppProps & {
Component: NextPageWithLayout;
err: any;
};
export default function MyApp({ Component, pageProps, err, ...appProps }: AppPropsWithLayout) {
const apolloClient = useApollo(pageProps.initialApolloState);
if (["/"].includes(appProps.router.pathname))
return (
<Component {...pageProps} err={err} />
);
const getLayout = Component.getLayout || ((page) => page);
return (
<ApolloProvider client={apolloClient}>
{getLayout(<Component {...pageProps} err={err} />)}
</ApolloProvider>
);
}
Do you think we can use the ApolloProvider in the getLayout functions of all the other pages? Will it persist between page changes?
I am trying to connect some component (USERS) to my store. I will show you each step.
First of all i create my store in index.js:
// composeWithDevTools helps to follow state changes, remove in production
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const sagaMiddleware = createSagaMiddleware();
const store = createStore(reducers, composeEnhancers(applyMiddleware(sagaMiddleware)));
//sagaMiddleware.run(usersSaga);
console.log('MYSTORE: ', store);
ReactDOM.render(
<Provider store={store}>
<App />
</Provider>,
document.getElementById('root'),
);
My reducer is coded in the following way:
import { combineReducers } from 'redux';
import usersReducer from './usersReducer';
export default combineReducers({
users: usersReducer,
});
Now my App.js file looks like this:
import React from 'react';
import { HashRouter, Route, Redirect } from 'react-router-dom';
import { AuthorisationMails } from './route-components/AuthorisationMails.js';
import { ChangePassword } from './route-components/ChangePassword.js';
import { Credits } from './route-components/Credits.js';
import { Graphs } from './route-components/Graphs.js';
import { Groups } from './route-components/Groups.js';
import { HeaderBar } from './components/HeaderBar.js';
import { Home } from './route-components/Home.js';
import { Login } from './route-components/Login.js';
import { MailServers } from './route-components/MailServers.js';
import { MailStatus } from './route-components/MailStatus.js';
import { Options } from './route-components/Options.js';
import { StatusMails } from './route-components/StatusMails.js';
import { Users } from './route-components/Users.js';
const App = () => (
<div>
<HashRouter>
<HeaderBar />
<Route path="/">
<Redirect to="/login" />
</Route>
<Route path="/login" component={Login} />
<Route path="/dashboard_user" component={Users} />
</HashRouter>
</div>
);
export default App;
In Users, i try to connect to the store with a mapstateToProps and connect as you see here:
import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';
import { connect } from 'react-redux';
import * as actions from '../redux/actions';
export class Users extends Component {
componentDidMount() {
console.log('USERPROPS: ', this.props);
}
render() {
return <div>Users</div>;
}
}
const mapStateToProps = state => {
console.log('USERSSTATE: ', state.user);
return {
users: state.userReducer,
};
};
export default withRouter(connect(mapStateToProps)(Users));
The problem here is that somehow i am connecting in the wrong way, since the console.log of USERPROPS does not contain a property user. It contains history location and match.
I tried connecting by using the following url https://react-redux.js.org/api/connect.
Any idea on why my component is not connecting to the store?
Solved it, i removed the brackets when importing components, thus for example:
import { Credits } from './route-components/Credits.js' => import Credits from './route-components/Credits.js'
I think you might need to use state.users.user:
const mapStateToProps = state => {
return {
users: state.users.user,
};
};
I am working on a redux project where I have a list of posts(like Blog Post) and each post has an unique id.Also,I have a different component which displays the detail of a particular post(I have named it Post_Detail component). So what I want to do is when I click on a particular post from the list of posts,I want to navigate to the page which displays the detail of that particular post.
My action creator for displaying a selected post is:
//Action Creator for displaying a selected post
export function fetchPost(id) {
const request = axios.get(`${API}/posts/${id}`,{headers});
return dispatch => {
return request.then(({data}) => {
console.log(data);
dispatch({
type: FETCH_POST,
payload: data
})
})
}
}
My Post_Detail component for displaying the selected post is:
import React, { Component } from 'react';
import { connect } from 'react-redux';
import { fetchPost, deletePost } from '../actions/posts_action';
class PostDetail extends Component {
componentDidMount() {
const { id } = this.props.match.params;
this.props.fetchPost(id);
console.log(id)
}
//Function for deleting on click using action creator
onDeleteClick() {
const { id } = this.props.match.params;
this.props.deletePost(id, () => {
this.props.history.push('/');
});
}
render() {
const { post } = this.props;
if (!post) {
return <div>Loading...</div>
}
return(
<div>
<div>
<h3>{post.title}</h3>
<h6>Categories: {post.category}</h6>
<p>{post.body}</p>
</div>
<button
className="btn btn-danger pull-xs-right"
onClick={this.onDeleteClick.bind(this)} >
Delete Post
</button>
</div>
);
}
}
function mapStateToProps({ posts }, ownProps) {
return { post: posts[ownProps.match.params.id] };
}
export default connect(mapStateToProps, { fetchPost, deletePost })(PostDetail);
My homepage for listing all the available posts is:
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware } from 'redux';
import { BrowserRouter, Route } from 'react-router-dom';
import thunk from 'redux-thunk';
import './index.css';
import App from './App';
import reducers from './reducers/index.js'
import Posts from './components/posts_index';
import CreatePost from './components/new_post';
import PostDetail from './components/post_detail';
import CategoryView from './components/category';
import { compose } from 'redux';
import { Link } from 'react-router-dom';
//const createStoreWithMiddleware = createStore(reducers,applyMiddleware(thunk));
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const createStoreWithMiddleware = createStore(reducers, composeEnhancers(applyMiddleware(thunk)));
ReactDOM.render(
<Provider store={createStoreWithMiddleware}>
<BrowserRouter>
<div>
<Route path="/new" component={CreatePost} />
<Route path="/posts/:id" component={PostDetail} />
<Route exact path="/" component={Posts} />
<Route path="/:category/posts" component={CategoryView} />
</div>
</BrowserRouter>
</Provider> , document.getElementById('root'));
So, what is happening now is if I try to navigate to the post using the "id" for that post in the url like : http://localhost:3000/posts/8xf0y6ziyjabvozdd253nd where "8xf0y6ziyjabvozdd253nd" is the id of that post,I can navigate to the Post_Detail component and see the details of that post.But,I am not able to figure out how to navigate to the Post_Detail component when the post is clicked from the list of posts in the homepage. I know that I should use a "Link" from 'react-router-dom' and navigate to the page passing in the url in "to" property of the link, but I don't know how to dynamically change the id in the link. Can anyone please guide me how to proceed?
