Your API on Steroids – Retrofitting GraphQL by Code, Cloud Native or Serverless

OOP 2023, Online, Februar 2023 (Sonja Wegner & Stefan Schmöller) Slides ansehen

With GraphQL a modern and flexible way of providing APIs for our data is emerging.
The clients specify which data they need, the provisioning of data becomes more flexible and dynamic. Over-fetching or under-fetching are history.
But does this mean we have to rewrite all APIs to benefit? How can we retrofit a GraphQL API onto our existing API landscape?

In this talk we explore three different alternatives:
– The Developer Way: Writing a GraphQL API layer by hand
– The Cloud-native Way: Using lightweight API gateways such as Gloo or Tyk
– The Serverless Way: Using Cloud Provider native services
We will look at all three approaches conceptually and justify when and why each makes sense. Additionally, we will show in a live demo how GraphQL APIs can be added to an existing REST API.
