Igor and the Holy Grail (Lighting Talk)

PyCon DE 2019 路 Oct 9, 2019

7 years ago I started my Holy Grail findings. After:

  • routr (and the attempt to make a web framework)
  • jsl (and the attempt to provide principles to build web applications for Flask, aiohttp.web or any web framework)
  • GraphQL (and abandoning REST API as a whole)

I've discovered OpenAPI 3 Schema and, thankfully to pyramid3_openapi, I've decided to rebuild my rororo library to bring OpenAPI 3 schema support to aiohttp.web applications.
