Summary

Throughout this chapter, we've seen how to use Apollo Client to send queries and mutations to our previously implemented backend API. We integrated Apollo with our Angular frontend, then implemented the required services and components for user authentication.

We have also added functionality to our application header to allow users to navigate between pages, such as the profile, home feed, and login pages. We used conditional rendering to display just the necessary buttons based on the user's authentication state. We added the necessary functionality to allow users to search for other users on the network using a search bar in the header. The results are then displayed in a dialog component that includes pagination and close buttons.

In the next chapter, we'll continue improving our authentication system and add unit testing to ensure our code works as expected.
