Yes, it's perfectly fine to use client components for all your pages in a Next.js application if they all require the use of useState or other client-side features. In Next.js, client rendering is opt-in, meaning you have to explicitly decide what components React should render on the client.
To declare a component as a client component, you can add the React "use client" directive at the top of a file, above your imports. This directive is used to declare a boundary between Server and Client Component modules. By defining a "use client" in a file, all other modules imported into it, including child components, are considered part of the client bundle.
Here's an example of a client component using useState:
'use client'
import { useState } from 'react'
export default function Counter() {
const [count, setCount] = useState(0)
return (
<div>
<p>You clicked {count} times</p>
<button onClick={() => setCount(count + 1)}>Click me</button>
</div>
)
}
Remember, Client Components can use state, effects, and event listeners, meaning they can provide immediate feedback to the user and update the UI. They also have access to browser APIs, allowing you to build UI for specific use cases[^1^].
However, keep in mind that if you're using third-party components that rely on client-only features, you may need to wrap them in your own Client Components if they don't yet have the "use client" directive[^2^].

Let me check the knowledge base for you. One moment! :books:
Yes, a Suspense component can re-render when state from other components is updated. This is especially true if the state change triggers a new asynchronous action that the Suspense component is waiting for.
In React, a Suspense component allows you to wait for some code to load and declaratively specify a loading state (like a spinner or placeholder). This is achieved by wrapping a component that performs an asynchronous action (like fetching data) in a <Suspense> component and providing a fallback UI to display while waiting[^1^].
Here's an example from the Next.js documentation:
import { Suspense } from 'react'
import { PostFeed, Weather } from './Components'
export default function Posts() {
return (
<section>
<Suspense fallback={<p>Loading feed...</p>}>
<PostFeed />
</Suspense>
<Suspense fallback={<p>Loading weather...</p>}>
<Weather />
</Suspense>
</section>
)
}
In this example, if the state in either PostFeed or Weather components changes and triggers a new fetch operation, the Suspense component will re-render and show the fallback UI until the new data is ready.
However, it's important to note that Suspense components can sometimes behave unexpectedly in certain scenarios. For instance, some users have reported issues with Suspense not rendering the fallback UI when search parameters change[^2^][^3^]. Others have found workarounds by using their own Suspense boundaries with a key prop[^4^].

To prevent the Suspense component for the Weather from re-rendering when the state of PostFeed changes, you need to ensure that the state change in PostFeed does not trigger a new fetch operation in Weather.
In React, a component re-renders when its state or props change. If the Weather component is somehow dependent on the state of PostFeed, it will re-render when that state changes.
To avoid this, you should isolate the state of these two components. Make sure that the state change in PostFeed does not affect Weather. If the two components need to share some state, consider lifting the state up to their closest common ancestor, but keep the state that they don't need to share separate.
Here's an example of how you might structure your components:
import { Suspense } from 'react'
import { PostFeed, Weather } from './Components'
export default function Posts() {
return (
<section>
<Suspense fallback={<p>Loading feed...</p>}>
<PostFeed />
</Suspense>
<Suspense fallback={<p>Loading weather...</p>}>
<Weather />
</Suspense>
</section>
)
}
In this example, PostFeed and Weather are separate components wrapped in their own Suspense components. As long as the state changes in PostFeed do not affect Weather, updating the state in PostFeed should not cause Weather to re-render.
However, if you're experiencing issues with Suspense re-rendering inappropriately, it might be due to known issues with Suspense in Next.js[^1^][^2^][^3^][^4^]. Some users have found workarounds by using their own Suspense boundaries with a key prop[^4^].

While it's technically possible to include a modal within a table row (<tr>), it's generally not recommended due to semantic and accessibility reasons. HTML tables are designed to present tabular data, and each table row should contain table cells (<td> or <th>). Including a modal within a table row could lead to unexpected behavior and might not be correctly interpreted by assistive technologies like screen readers.
In your case, it would be better to manage the modal at a higher level in your component hierarchy, outside of the UserTableItem component. You could lift the state up to the parent component and conditionally render the ConfirmationModal based on that state.
Here's a simplified example:
import { useState } from 'react';
import UserTableItem from './UserTableItem';
import ConfirmationModal from '@components/Modal/ConfirmationModal';
function UserTable({ users }) {
const [modal, setModal] = useState(false);
const [selectedUser, setSelectedUser] = useState(null);
const handleDeleteUser = (userId) => {
// delete user logic here
setModal(false);
};
const handleOpenModal = (userId) => {
setSelectedUser(userId);
setModal(true);
};
return (
<>
<table>
{users.map((user, index) => (
<UserTableItem
key={user._id}
index={index}
data={user}
onClickDelete={() => handleOpenModal(user._id)}
// other props here
/>
))}
</table>
{modal && (
<ConfirmationModal
confirmedModal={() => handleDeleteUser(selectedUser)}
cancelModal={() => setModal(!modal)}
isOpen={modal}
subtTitle="Are you sure u want to delete this user?"
/>
)}
</>
);
}
