Swagger is a tool for documenting APIs, primarily driven from a coding side and a universal docs client.
When our API is used by anything running in a browser and it this thing running in the browser was not loaded from the same domain our API is running, we will encounter a concept called CORS.
I’ve been working on the Kanban tutorial app to make it a better tutorial application. This week, I am going to talk about changes and why and how I implemented them.
The RestTemplate is a little helper class that makes calling web requests an easier. Instead of wrangling with protocols and transformation by ourselves, we get that out of the box by Spring MVC.
Spring Boot is not only for server applications. Did you know you can write command line apps too?
Our API works now. We can register a new user, log in via the API, authenticate via token in a header and can work with the kanban board. So, we are done for now.
Now that we can register a new user and login, it is time for assigning boards to the logged in user.
We will be using Spring Session with a JDBC storage and use the same database as for the rest of the application.
Microservices are not the holy grail of software development as many devs and managers see them. They don’t solve all your problems at once, not even the tech ones. Yet, they follow a fad blindly again. Yesterday it was Agile and SOA, today it’s still microservices and cloud. Instead of solutions, many find themselves facing new problems; worse problems.
The API will expose endpoints for login and register new users.
