Installing it is as easy as performing the following command in your terminal:

npm install @ngrx/effects --save

The next step is to set it up. The setup can be seen as consisting of two steps:

• Create our effect
• Register the effect with the EffectsModule

An effect is just an injectable service that listens for a specific action. Once the effect is in focus, it can carry out a number of operations and transformations before leaving over control. It leaves over control by dispatching an action.
