API doc

Rest

Visit the documentation endpoint to see the swagger docs. Available at [/docs]((http://localhost:8080/docs) running project locally

The task queue can be interacted with by making a post request to /reverse and providing a body consisting of:

• delay(int) -> time in seconds to delay the task by
• text(string) -> any text to be reversed

NB The task queue runs synchronously as it blocks for the number of seconds specified. It is just a proof of concept; can't think of any basic use for it in this project.

The graphql endpoint is available at /graphql
