How hard would it be to adapt this style of resilience driven development to other languages? You mention having to make several improvements to the core algorithms when faced with truly concurrent code. For example, could microservice architectures in node.js use your methods/application?

For sure, the algorithm changes that we made we believe work across all languages; they are inherent to the architecture of microservice applications and not specific to a particular programming language.

That said, we currently do not have any client libraries for node.js. Therefore, we would probably have to make a client library for the common GRPC and HTTP libraries that are used in node.js. As I am not a node.js programmer, I do not know what they are. However, since we have written client libraries for Python (HTTP and GRPC clients) and Java (one HTTP client and the primary GRPC client), we believe this is a "small matter of programming."
