javascript - Fetching data with redux actions -


i having issue internally how structure redux actions fetch data via rest api.

i fetching variety of data like

  • all posts published
  • a singular post
  • all current users
  • search results

i wondering if create action fetch's data each endpoint or if create singular fetch action fetches data supplied route?

current implementation:

function requestposts(site) { return {     type: request_posts,     site }  function fetchposts(site) { return dispatch => {     dispatch(requestposts(site))     return fetch(`http://notareallink.com/posts`)         .then( response => response.json() )         .then( json => dispatch( receiveposts( site, json ) ) ) }  function requestpost(site) { return {     type: request_post,     site }  function fetchpost(site) { return dispatch => {     dispatch(requestpost(site))     return fetch(`http://notareallink.com/post/post-id`)         .then( response => response.json() )         .then( json => dispatch( receivepost( site, json ) ) ) }  function requestusers(site) { return {     type: request_users,     site }  function fetchusers(site) { return dispatch => {     dispatch(requestusers(site))     return fetch(`http://notareallink.com/users`)         .then( response => response.json() )         .then( json => dispatch( receiveusers( site, json ) ) ) }

to me feels load of duplicate code doing same thing (fetching data endpoint).

is correct way or should creating singular action data fetch , pass relevant route?

i sorry if not clear trying wrap head around type out.

all of functions can call functions handle repetative tasks w/o code duplication.

first of need extract repetative fetch calls.

const callapi = url => fetch(`http://notareallink.com/${url}`).then(res => res.json())

to avoid repetative action dispatching can use middlewares. seems have thunk middleware. can add own or use package.

const promisemiddleware = ({dispatch}) => next => action => {    const {promise, pending, success, fail} = action    if(promise) {      dispatch(pending());      promise.then(        res => dispatch(success(res)),        err => dispatch(fail(err))      )    }    return next(action) }

and use this

const requestposts = () => ({ type: request_posts }) const recieveposts = posts => ({ type: recieve_posts, posts }) const requestpostsfail = reason => ({ type: request_posts_fail, reason })  const fetchposts = () => dispatch => dispatch({   promise: callapi('posts'),   pending: requestposts,   success: receiveposts,   fail: requestpostsfail })
