We have finally learned how to integrate our Ionic App with any backend and add life to our app. Ionic App will be enabled now to fetch and store data from any custom-made web service or easy-to-use mBaaS available on the market. We have seen how to create Ionic services and use them in multiple views or controllers. MbaaS seems to be a perfect choice for wiring up a quick backend to your Ionic App. Firebase and Parse are the recommended mBaaS with wide community support. In the next chapter we will learn about testing our app on real devices.
