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>
);
} );
}
import { Container } from 'react-bootstrap'
import { useDispatch, useSelector } from 'react-redux'
import Layout from '../../components/Layout/Layout'
const CartScreen = () => {
const cart = useSelector(state => state.cart)
const { cartItems } = cart
console.log(cartItems)
return (
<Layout>
<Container>
<div>
<h1>Shopping Cart</h1>
{cartItems && cartItems.length === 0 && <p>Your cart is empty </p>}
</div>
</Container>
</Layout>
)
}
export default CartScreen
This code gives me that Hydration Error only when 'cart' is empty
I don't know how to use useEffect on this and I use redux toolkit.
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.

I'm currently working on a site that pulls Reddit data from different subreddits to show recipes, you can toggle between 3 different ones. That part works fine! I'm able to pull the list of posts from each subreddit, but now I'm trying to make it so when you click a button, it routes you to post details where it'll show the post and comments. I have to do another API call to get that information.
Somewhere along the way, it's getting messed up and it's showing "xhr.js:210 GET https://www.reddit.com/r/recipes/comments/[object%20Object].json 404:" It's a dynamic route, so there are two different parameters I'm trying to use. I did try and console log the parameter for ID(the one showing up as [object object] and it shows up fine by itself and is not an object from what I can tell.
Please see some of the code below where I think things could be going wrong. I'm guessing it's the API call because when I console log it, it only shows the subreddit as an arg but not sure..

Any help would be appreciated, because I'm lost!
Thanks!
I figured it out today, for those interested!
I finally got it! I figured I was doing something wrong with react router, and that's why I couldn't get it to work but I didn't want to stop using react router. I tried many different ways to fix it, including putting both arguments in an object, I tried changing it by passing what I needed with a pathname AND a state, but the state didn't work right. think that I was passing the state in an incorrect way somehow. I think I wrote it like state{ permalink: data.permalink} or something. I also tried changing it so it only took one parameter, but for some reason the react router Link only wanted to use the post IDs and would go to my page not found if I tried to use permalink. After researching other ways to pass data using React Router, I landed on using From to grab the data from the previous page the user was on and used useLocation to grab the state.
Here is a snippet of what I changed in Link for in PostCard.js. The data was passed in props from postListing.js, just for reference:
return (
<div className="card mb-3 mx-auto text-center" style={{width: "70%"}}>
<div className="row g-0">
<div className="col-md-5">
{mediaRender()}
</div>
<div className="col-md-7">
<div className="card-body">
<h5 className="card-title">{parse(data.title)}</h5>
<div className="card-text">{renderSelf()}</div>
<div className="card-text"><small className="text-muted">By {data.author}</small></div>
<Link to={`/post/${data.id}`}
state={{ from: data}}>
<button className="btn btn-primary">Go to post</button>
</Link>
</div>
</div>
</div>
</div>
)
}
I also stopped using the postId to try and make the API call, and instead only used it to make the dynamic link to the component. After that, I used From's state to grab the permalink(from previous reddit post data) to make the API call to get the comment information.
Here is a snippet of PostDetails.js where I made the changes:
function PostDetails() {
const location = useLocation();
const {from} = location.state;
const comments = useSelector(getSelectedPost);
const dispatch = useDispatch();
useEffect( () => {
dispatch(getPostComments(from.permalink));
}, [dispatch]);
I also found out I was trying to access the data incorrectly in my API call, as the data was structured differently than I originally thought.
Here is the changed thunk in PostSlice.js:
export const getPostComments = createAsyncThunk('posts/getPostComments', async (permalink) => {
const response = await fetch(`http://www.reddit.com${permalink}.json`);
const json = await response.json();
return json[1].data.children.map((comment) => comment.data)
});
There were multiple things wrong with my react app, but hopefully this helps someone else! :)
The second argument to createAsyncThunk is the payloadCreator.
It's called with two arguments, arg which is a single value, and the thunkAPI object.
// First, create the thunk
const fetchUserById = createAsyncThunk(
'users/fetchByIdStatus',
async (userId, thunkAPI) => {
const response = await userAPI.fetchById(userId)
return response.data
}
)
// Later, dispatch the thunk as needed in the app
dispatch(fetchUserById(123))
You are passing the thunkAPI argument as the postID value in the GET request.
export const fetchAsyncPostsDetail = createAsyncThunk(
'posts/fetchAsyncPostsDetail',
async (sub, postID) => {
const response = await redditApi.get(`${sub}/comments/${postID}.json`)
return response.data.data.children;
}
);
If you need to pass multiple values to your thunk then pack them into a single object.
export const fetchAsyncPostsDetail = createAsyncThunk(
'posts/fetchAsyncPostsDetail',
async ({ sub, postID }, thunkAPI) => {
const response = await redditApi.get(`${sub}/comments/${postID}.json`)
return response.data.data.children;
}
);
...
useEffect(() => {
dispatch(fetchAsyncPostsDetail({ sub, postID }));
}, [dispatch, postID, sub]);
