|
| 3 | * Convenience utility to create action based middleware that supports async processes more easily.
|
| 4 | * All hooks are called for both synchronous and asynchronous actions. Except that either `onSuccess` or `onFail` is called
|
| 5 | *
|
| 6 | * The create middleware tracks the process of an action (assuming it passes the `filter`).
|
| 7 | * `onResume` can return any value, which will be passed as second argument to any other hook. This makes it possible to keep state during a process.
|
| 8 | *
|
| 9 | * See the `atomic` middleware for an example
