R1D40 Swagger and OpenAPI

| programming |

I first learned about Swagger when I started working at LaunchDarkly since our REST API follows the OpenAPI specification. This is such an amazing tool. I am sad that I did not learn about it before.

Swagger and OpenAPI allow you to create a spec for your REST API. You can then use some tooling in order to create clients in pretty much every language under the sun for your API.

It took me a few solid days to write a python wrapper for the CircleCI API. In the same amount of time, I could have theoretically written a swagger spec and made clients for all the languages.

I spent a few hours today looking through the documentation for Swagger and learning more about tooling. Why doesn’t every product use this?
