Enhancing User Experience with Daxus |
https://dev.to/jason89521/enhancing-user-experience-with-daxus-1f2f
|
Enhancing User Experience with DaxusDaxus is an exceptional server state management library tailored for React applications With Daxus developers have complete control over their data allowing them to craft websites with superior user experiences Building a Better User Experience with DaxusLet s consider the scenario of developing a forum website Our website comprises various lists of posts such as popular latest recommended and more Users can interact with the posts for example by liking them and the post will display the total number of likes Initially we might opt for React Query to manage the server data Here s an example of how we could use React Query import useQuery useInfiniteQuery from tanstack react query export function usePost id number return useQuery queryKey post detail id queryFn gt axios get api post id export function usePostList forumId filter forumId string filter popular latest recommended return useInfiniteQuery queryKey post list forumId filter queryFn pageParam gt axios get api post page pageParam amp forumId forumId amp filter filter getNextPageParam lastPage pages gt lastPage nextCursor React Query provides the useQuery and useInfiniteQuery hooks to simplify data handling With just the queryKey and queryFn React Query efficiently manages the data for us Now let s address the logic of users liking a post import useMutation useQueryClient from tanstack react query export function useLikePost id number const client useQueryClient return useMutation mutationFn gt return likePostApi id onSuccess gt client invalidateQueries queryKey post When a user likes a post we invalidate all post data triggering a refetch of the post the user is currently viewing Moreover when the user returns to the post list it is also refetched displaying the updated like count However there is a noticeable delay between the user liking a post and the post displaying the updated like count To address this in the post view we can implement optimistic updates export function useLikePost id number const client useQueryClient return useMutation mutationFn gt return likePostApi id onMutate async gt await client cancelQueries queryKey post detail id client setQueryData post detail id old gt old likeCount old likeCount onError gt client setQueryData post detail id old gt old likeCount old likeCount onSettled gt client invalidateQueries queryKey post Now users can immediately see the result after liking a post However when they return to the post list they still see the old post data They have to wait for some delay to see the latest result Considering the multiple lists on our website finding the post in every list and then performing an optimistic update isn t efficient Daxus to the Rescue Enter Daxus With Daxus we can create a custom data structure for our post data ensuring that each post entity references the same data This feature allows us to eliminate the delay issue without any hassle Let s see how we can use Daxus to manage the post data import createDatabase createPaginationAdapter useAccessor from daxus export const database createDatabase export const postAdapter createPaginationAdapter lt Post gt export const postModel database createModel name post initialState postAdapter initialState export const getPost postModel defineAccessor name getPost async fetchData id number return axios get api post id syncState draft data postAdapter upsertOne draft data export const listPost postModel defineInfiniteAccessor name listPost async fetchData forumId filter forumId string filter popular latest recommended previousData const page previousData nextCursor return axios get api post page page amp forumId forumId amp filter filter syncState draft data arg forumId filter const key forumId amp filter postAdapter appendPagination draft key data export function usePost id number return useAccessor getPost id state gt postAdapter tryReadOne state id export function usePostList forumId filter forumId string filter popular latest recommended return useAccessor listPost forumId filter state gt const key forumId amp filter return postAdapter tryReadPagination state key items export async function likePost id number postModel mutate draft gt postAdapter readOne draft id likeCount try await likePostApi id catch postModel mutate draft gt postAdapter readOne draft id likeCount finally postModel invalidate In Daxus we provide the necessary instructions on how to update our state after fetching the data from the server The createPaginationAdapter function returns an object with operations for accessing pagination data If we need a more customizable data structure we can build our adapter as well Since each entity in the pagination data structure references the same data when a user likes a post and returns to any list they will immediately see whether they have liked that post No delays no fuss just a seamless user experience For more detailed information and code examples please visit the Daxus GitHub repository Daxus is continually evolving and your valuable feedback is crucial to making it even better Give Daxus a try and share your thoughts with us Let s create remarkable React applications together |
