Use with Promises Resolved with Null Values
If a promise is resolved with a
null
or undefined
value, the fullfilled action will not include a payload property. This is because actions describe changes in state. Consider the following two actions:// A
{
type: 'ACTION`,
meta: ...
}
// B
{
type: 'ACTION'
payload: null,
meta: ...
}
Both actions describe the same change in state. This is why, when you resolve with
null
or undefined
, the payload property is not included. It would be redundant to include it.
