Paginated Queries

Example: Pagination

Paginated queries are queries that return a list of results in incremental pages.

This can be used to build components with "Load More" buttons or "infinite scroll" UIs where more results are loaded as the user scrolls.

Using pagination in Convex is as simple as:

  1. Writing a paginated query function that calls .paginate(opts).
  2. Using the usePaginatedQuery React hook.

Like other Convex queries, paginated queries are completely reactive.

Writing Paginated Query Functions

Convex uses cursor-based pagination. This means that paginated queries return a string called a Cursor that represents the point in the results that the current page ended. To load more results, you simply call the query function again, passing in the cursor.

To build this in Convex, define a query function that:

  1. Takes PaginationOptions as its first argument.
    • This is an object with numItems and cursor fields.
    • You may include additional arguments as well.
  2. Calls .paginate(opts) on a database query, passing in the PaginationOptions and returning its result.
import { query } from "./_generated/server";

export default query(async ({ db }, opts) => {
return await db.query("messages").order("desc").paginate(opts);

Paginating within React Components

To paginate within a React component, use the usePaginatedQuery hook. This hook gives you a simple interface for rendering the current items and requesting more. Internally, this hook manages the continuation cursors.

The arguments to this hook are:

  • The name of the paginated query function.
  • An options object with the initialNumItems to load on the first page.
  • Any additional arguments that the query function expects.

The hook returns an object with:

  • results: An array of the currently loaded results.
  • status: The status of the pagination. The possible statuses are:
    • "CanLoadMore": This query may have more items to fetch. Call loadMore to fetch another page.
    • "LoadingMore": We're currently loading another page of results.
    • "Exhausted": We've paginated to the end of the list.
  • loadMore(n): A callback to fetch more results. This will be undefined unless the status is "CanLoadMore".
const { results, status, loadMore } = usePaginatedQuery("listMessages", {
initialNumItems: 5,


Like any other Convex query functions, paginated queries are completely reactive. Your React components will automatically rerender if items in your paginated list are added, removed or changed.

One consequence of this is that page sizes in Convex may change! If you request a page of 10 items and then one item is removed, this page may "shrink" to only have 9 items. Similarly if new items are added, a page may "grow" beyond its initial size.
