API First development with OpenAPI - You should you practise it !? by Nick Van Hoof

Very excellent presentation I've ever seen. Good job Nick!

I think postman also solves the problem while you can share your collection or create a team and invite them.

Dear All and Devoxx Team,
Good Presentation about Open API. Please help me certain technical questions related to Open API.
My Understanding of Open API
--------------------------------------------------
1) Open API definition shall be designed using tools which will generated YAML or RAML file.
2) To make use of this RAML or YAML file , I can generate the Validation module for example from java or any technology such as .NET ,....etc.
3) Finally Open API is request and response would be JSON....then it should be REST API.
Again if say REST API , I have two options two deploy it.
----------------------------------------------------------------------------------------
First Option- I can deploy my Open API(REST API) into any application server and the Second Option is that to deploy t as Micro services.
During the explanation, Taking about API Gateway, My question is on API Gateway.

Questions to you
------------------------------

1)With respect to API Gateway - Should i have to go with IBM DP ,, Oracle DP or KAFKA Server for this API Connect ?
2) How to Secure Open API in terms of Data Integrity and Data Transmission Security?. The reason for asking this question to you is that I am having scope of deploying this Open API to my clients who are going to access these services?

Thank you, I enjoyed a lot this brief but essential info of OpenAPI. One thing I was looking for as well was how to JUnit-test (probably by @SpringBootTest & MockMvc?) through a controller. Is there a good example? Thanks for answers from anyone in advance. ;)

Great talk. Man... it's so easy to get lost in all of the terms. You've made it easy to understand!

Communication is the only problem in the world, all others stem from some form of bad communication.

No comments in a whole year? OpenAPI nicely summarized Nick! I especially liked the one page diagram towards the end and coverage of AWS API Gateway and Postman imports of the YAML. The negatives of code regeneration remain, as you indicated with your enumeration example, hopefully minimized via proper versioning and communication to customers.
