Pagination

Hi everyone Anyone already did pagination or infinite scrolling on Solid? If yes, can share how to do it please? I found a primitive for that, but I can't use the data fetching I have with the createInfiniteScroll. This is my second attempt:

const [searchParams, setSearchParams] = useSearchParams();

  const totalOfProjects = createAsync(() => getTotalOfProjects());

  const [paginationProps, page, setPage] = createPagination({
    pages: Math.ceil((totalOfProjects() ?? 0) / DEFAULT_PAGINATION_OFFSET),
  });

  const projects = createAsync(() => getProjects(page()));

  createEffect(() => {
    setSearchParams({
      page: page(),
    });
  });

const [searchParams, setSearchParams] = useSearchParams();

  const totalOfProjects = createAsync(() => getTotalOfProjects());

  const [paginationProps, page, setPage] = createPagination({
    pages: Math.ceil((totalOfProjects() ?? 0) / DEFAULT_PAGINATION_OFFSET),
  });

  const projects = createAsync(() => getProjects(page()));

  createEffect(() => {
    setSearchParams({
      page: page(),
    });
  });

Where The getProjects is:

const getProjects = cache(async (page = 1): Promise<GetProjectsQueryResult> => {
  'use server';

  try {
    const { start, end } = getPagination(page);

    return client.fetch<GetProjectsQueryResult>(getProjectsQuery, {
      start,
      end,
    });
  } catch {
    return [];
  }
}, 'projects');

const getProjects = cache(async (page = 1): Promise<GetProjectsQueryResult> => {
  'use server';

  try {
    const { start, end } = getPagination(page);

    return client.fetch<GetProjectsQueryResult>(getProjectsQuery, {
      start,
      end,
    });
  } catch {
    return [];
  }
}, 'projects');

Thanks 🙏

I'm trying to use that Any problem to do this:

  const [searchParams, setSearchParams] = useSearchParams();

  const totalOfProjects = createAsync(() => getTotalOfProjects());

  const [paginationProps, page, setPage] = createPagination({
    pages: Math.ceil((totalOfProjects() ?? 0) / DEFAULT_PAGINATION_OFFSET),
  });

  const projects = createAsync(() => getProjects(1));

  createEffect(() => {
    setSearchParams({
      page: page(),
    });
  });

  const [searchParams, setSearchParams] = useSearchParams();

  const totalOfProjects = createAsync(() => getTotalOfProjects());

  const [paginationProps, page, setPage] = createPagination({
    pages: Math.ceil((totalOfProjects() ?? 0) / DEFAULT_PAGINATION_OFFSET),
  });

  const projects = createAsync(() => getProjects(1));

  createEffect(() => {
    setSearchParams({
      page: page(),
    });
  });

I try to use createInfiniteScroll but didn't work

The problem here is that when totalOfProjects changes, pages is not updated. wrap the options in a function to make them reactive: createPagination(() => ({ pages: ... })). I haven't written infinite scrolling, so I need to have a closer look once I have some time.

Thanks 🙏

happy to help. The use of reactivity in createPagination was a fun exercise. It is as fine-grained as possible.

Daniel Sousa @TutoDS•3mo ago

Is my first time using Solid, so thank you for your help and sorry for any noob question
