Javascript Question

Use reselect selector with parameters

How do I pass additional parameters to combined selectors? I am trying to

• Get data

• Filter data

• Add custom value to my data set / group data by myValue

export const allData = state => state.dataTable
export const filterText = state => state.filter.get('text')

export const selectAllData = createSelector(
(data) => data

export const selectAllDataFiltered = createSelector(
[ selectAllData, filterText ],
(data, text) => {
return data.filter(item => {
return item.name === text

export const selectWithValue = createSelector(
[ selectAllDataFiltered ],
(data, myValue) => {
return data

let data = selectWithValue(state, 'myValue')

The answer to your questions is detailed in an FAQ here: https://github.com/reactjs/reselect#q-how-do-i-create-a-selector-that-takes-an-argument

In short, reselect doesn't support arbitrary arguments passed to selectors. The recommended approach is, instead of passing an argument, store that same data in your Redux state.
