Pagination

In this guide, you'll learn how to implement pagination in your Rapture application to efficiently manage and display large sets of data.

Introduction to Pagination

Pagination is a technique used to divide a large dataset into smaller, more manageable chunks called pages. This allows users to navigate through data in a structured manner, improving user experience and performance.


Basic Pagination Setup

To implement basic pagination in your Rapture app, follow these steps:


  1. Retrieve Data: Fetch the complete dataset from your data source, such as an API.

  2. Set Page Size: Determine the number of items you want to display per page (e.g., 10 items per page).

  3. Calculate Total Pages: Divide the total number of items by the page size to calculate the total number of pages.

  4. Display Data: Display the items for the current page to the user.

Adding page navigation controls allows users to move between pages. You can use buttons, links, or other UI components to achieve this. Here's an example of how you can implement next and previous page navigation:

javascript

// api.js


export async function fetchMessages(conversationId, page = 1, limit = 10) {

const response = await fetch(

`/api/messages?conversation_id=${conversationId}&page=${page}&limit=${limit}`

);


if (!response.ok) {

throw new Error('Failed to fetch messages');

}


const data = await response.json();

return data;

}

In this example, fetchDataForPage is a function that retrieves data specific to the current page and updates the UI accordingly. The nextPage and previousPage functions control the navigation, ensuring that users can't navigate beyond the total number of pages.

For more advanced pagination techniques, you can explore:

  • Infinite Scrolling: Load new data as the user scrolls, providing a seamless browsing experience.

  • Displaying Page Numbers: Show a list of page numbers, allowing users to jump to specific pages.

  • Caching: Store previously fetched pages to reduce redundant API calls.

  • Provide clear navigation controls for users to move between pages.

  • Indicate the current page and total number of pages to users.

  • Optimize API requests to fetch only the data needed for the current page.
