A drop-in replacement for `redux-thunk` that allows middleware to detect that a thunk has been dispatched from within another thunk
npm install redux-thunk-recursion-detectredux-thunk that allows other middleware to detect that a thunk has been dispatched from within another thunk.dispatch call stack is important.I wrote an explanation that helps understand one such case in redux-thunk-error-handler's thunkErrorHandling.md
``bash`
npm install redux-thunk-recursion-detect
Normally, you can just replace anywhere you're using redux-thunk with this library instead.
`js
import { createStore, applyMiddleware } from 'redux';
import thunkMiddleware from 'redux-thunk-recursion-detect';
const store = createStore(myReducerFn, applyMiddleware(thunkMiddleware));
`
Then, in some other middleware that needs to know whether or not a thunk was dispatched from inside another thunk, you can use the isNestedThunkSymbol export to test for it.
`js
import { isNestedThunkSymbol } from 'redux-thunk-recursion-detect';
export const myCoolMiddleware = store => next => action => {
if (typeof action === 'function' && action[isNestedThunkSymbol]) {
// The thunk that is currently in the dispatch pipeline is a nested thunk.
doWhateverINeedForNestedThunks();
return next(action);
} else {
// The thunk is at the top level of its call stack
return next(action)
}
}
``
Take a look at redux-thunk-error-handler to see a real application of this middleware.
