Action creators

JavaScript functions that take some arguments and return actions are action creators. Let's look at an action creator function for adding a new doctor to the application:

function addNewDoctor(data) {
 return {
   type: ADD_NEW_DOCTOR_REQUEST,
   data
 };
}

Now, you can think of a function that you might need for deleting a record, as follows:

function deleteDoctor(identifier) {
 return {
   type: "DELETE_DOCTOR_REQUEST",
   identifier
 };
}

Before we move on to reducers, let's make one more action creator for authentication. Generally, to authenticate, we use an email and password. So, in order to authenticate (or deauthenticate) we need to define actions. Please note that the actions that we define will be used in our project for a hospital management system. Our action for authentication could look something like the following:

export const authenticate = (credentials) => ({
 type: "AUTHENTICATE",
 payload: credentials
});
export const deauthenticate = () => ({
 type: "DEAUTHENTICATE"
});

Similarly, let's create action creators for registering a user. When we register a user, we are likely to have a request, a success, or a failure. Based on these three states, we can create the action creators, as follows:

export const onRegisterRequest = user => ({ type: REGISTER_REQUEST, user });

export const onRegisterSuccess = user => ({ type: REGISTER_SUCCESS, user });

export const onRegisterFailure = message => ({
  type: REGISTER_FAILURE,
  message,
});
