海外TECH	DEV Community	Pagination in Javascript and React, with a custom usePagination() hook	https://dev.to/damiisdandy/pagination-in-javascript-and-react-with-a-custom-usepagination-hook-1mgo	Pagination in Javascript and React with a custom usePagination hookThis guide is to help you understand the concept of pagination and how to implement it in react the concepts in this tutorial can be applied to any javascript project What is Pagination Pagination is the process of separating print or digital content into discrete pages For print documents and some online content pagination also refers to the automated process of adding consecutive numbers to identify the sequential order of pages Concept behind it Let s say you have a total of items on a page and you want to only display items at a time per page This means we are going to have a total of pages and if we want to display items per page this means a total of you guessed it pages This formular is rather simple totalPages totalContent contentPerPage Implementing it in Javascript slice Calculating the content per page is rather easy but how do we display certain content based on what page we are on We simply need to understand the relationship between the page and the index of our content Let first understand the slice Array method The slice method returns a shallow copy of a portion of an array into a new array object selected from start to end end not included where start and end represent the index of items in that array The original array will not be modified For example let s say we have an array called scouts and we want to select only a portion of this array based on the array s index const scouts levi hange erwin petra oruo miche scouts slice output erwin petra oruo scouts slice output hange erwin We all know javascript follows a zero based index so the first parameter is the index from which we want to start the slice from and the second parameter is the index right after where we want the slice to end e g if we want to we use slice as seen in the first example Mapping page number to indexAll we need to do is know what the startIndex and lastIndex should be based on the page number this relationship is quite simple As you can tell from the diagram above the last index is simply the current page multiplied by the given content by page while the first index is the content by page subtracted from the last index assuming we are on page oneconst page const contentPerPage const lastIndex page contentPerPage const firstIndex lastIndex contentPerPage scouts slice firstIndex lastIndex scouts slice gt levi hange erwin page scouts slice gt petra oruo miche Wow that was easy Custom usePagination hook Now that we ve learned the concept behind it let s implement this in react and create our custom hook to help us automate this process This hook takes in an object that takes in the properties contentPerPage which is how many items should be displayed at a time and count which is the total number of items given Array length It also returns an object with the following properties page current page we are ontotalPages total number of pages generatedfirstContentIndex first index for the slice methodlastContentIndex last index for the slice methodnextPage function to navigate one page fowardprevPage function to navigate one page backwardsetPage function to go to a certain pageThe type definitions are as follows interface UsePaginationProps contentPerPage number count number interface UsePaginationReturn page number totalPages number firstContentIndex number lastContentIndex number nextPage gt void prevPage gt void setPage page number gt void type UsePagination UsePaginationProps gt UsePaginationReturn In your React project create a folder called hooks and create a file called usePagination this is where our custom hook will reside Type the following within itimport useState from react const usePagination UsePagination contentPerPage count gt const page setPage useState number of pages in total total items content on each page const pageCount Math ceil count contentPerPage index of last item of current page const lastContentIndex page contentPerPage index of first item of current page const firstContentIndex lastContentIndex contentPerPage change page based on direction either front or back const changePage direction boolean gt setPage state gt move forward if direction if page is the last page do nothing if state pageCount return state return state go back else if page is the first page do nothing if state return state return state const setPageSAFE num number gt if number is greater than number of pages set to last page if num gt pageCount setPage pageCount if number is less than set page to first page else if num lt setPage else setPage num return totalPages pageCount nextPage gt changePage true prevPage gt changePage false setPage setPageSAFE firstContentIndex lastContentIndex page export default usePagination We are managing the current page value with useState also notice that pageCount is also equal to the value of the last page I ve made the code above as explanatory as I can Implementation We simply import the hook then input the needed properties const firstContentIndex lastContentIndex nextPage prevPage page setPage totalPages usePagination contentPerPage count people length Then we simply slice our data with the firstContentIndex and lastContentIndex lt div className items gt people slice firstContentIndex lastContentIndex map el any gt lt div className item key el uid gt lt div gt lt div gt Below is a simple functionality to help us generate our buttons then we add their corresponding onClick handlers lt div className pagination gt lt p className text gt page totalPages lt p gt lt button onClick prevPage className page gt amp larr lt button gt ts ignore Array totalPages keys map el gt lt button onClick gt setPage el key el className page page el active gt el lt button gt lt button onClick nextPage className page gt amp rarr lt button gt lt div gt We are done As you can see below our usePagination hook works as planned Thank you for reading If you have any questions additions or subtractions please comment below The full source code to with project with a functioning todo application is linked below damiisdandy use pagination a react usePagination hook	2021-10-09 11:37:09
