cockatiel
After Mixer was acquired by Microsoft to become part of Xbox, we started migrating many of our services to .NET to take advantage of Xbox Live's tooling and infrastructure.
In these services, we used the wonderful Polly project to deal with transient failures and fault-handling—particularly important in our move to microservices. I missed having a similar tool in my Node.js work, so I wrote Cockatiel.
At some point, I'll write some blog posts about fault handling.
