GraphQL Will Do To REST What JSON Did To XML

Why GraphQL will become the new standard for accessing external data in your application. I will show how using GraphQL instead of REST services the development process becomes even more declarative as GraphQL will take away the (imperative) hassle of tying data from multiple endpoints together. This will increase the level of complexity in frontend development, while also increasing the performance of the application.

Testing GraphQL: From Zero To Hundred Percent

Testing is important for every project, whether it's a web application or api service. But writing scripts to test your application can be a hassle, especially for specific frameworks or tools like GraphQL. Sure, you could just test using Jest, Enzyme or any other testing tool out there for JavaScript applications. But how do you specifically test your GraphQL schemas and queries?
