Hasura DDN is introducing preview deployments for GraphQL APIs enabling zero downtime production deployments and rollbacks.

We recently rolled out a new CI system at Hasura and we are writing this post to take you on a journey about why and how we did it. This is a collection of ideas and implementation details which we believe to have helped us arrive at an optimal solution that worked out for us.

We want to setup a git push workflow to deploy our functions on AWS Lambda with API Gateway.

Schema migrations using Hasura CLI can version control and reproduce schema along with sample data.
