When implementing a comment feature in a web application, the logic should be divided between the client-side and server-side for optimal performance and security.
On the client-side (e.g., in React or Angular), you can build a form UI to let users enter their comment. Once submitted, this data is sent to the server using a POST request.
On the server-side (e.g., in Node.js, Django, or PHP), you handle the request, validate the input, check for authentication, and then save the comment in a database.
Example:
Let’s say you're building a real-time discussion feature for a website that shares lottery sambad results. Users may want to quickly comment when the latest result is posted.
The client will display the result and have a text box underneath to enter a comment.
When the comment is submitted, it is sent to the server, where you can check if it’s appropriate (no spam or abusive words) and then store it.
The server then responds, and the client shows the comment on the page instantly using JavaScript or WebSocket for real-time updates.
This setup ensures fast interaction for the user and reliable data handling on the backend.
