Multiple calls with dependencies redux-thunk
There might be several approaches depending of your requirements.
If the purpose is to load, initially users, and then their post, i would call firstly /users, and then dispatch another action creator to get their /posts.Because getting it all together would make your users waiting longer for something to change in the UI (ex: loading spinner), thus i would split these in two separate actions.
export function getUsers(group_id) => { return async dispatch => { const users = await API.get(`/users?group_id=${group_id}`); dispatch(loadUsersAction(users)); return users; };};export function getPostForGroupUsers (group_id) => { return async dispatch => { const users = await dispatch(getUsers(group_id)); const posts = await axios.all([...getPosts(users)]); dispatch(loadPostsAction(posts)); return posts; }}// or just call users, dispatch and get them from storeexport function getPostForAllUsers () => { return async dispatch => { // this depends on your implementation const users = getFromReduxStore('users'); const posts = await axios.all([...getPosts(users)]); dispatch(loadPostsAction(posts)); return posts; }}Maybe you can provide more details of your case, I then could give more precise response.
