This is the third post of building a basic web application using Plug.Router, Ecto, and the Postgres jsonb datatype. In this post we clean up the snapshot schema a bit and then handle the post logic. In the end, the application has the basic post and get routes, stores records in the database, and of course still deploys through our CI pipeline.
