QLutch (open source)

QLutch is a caching tool that enables developers to install a cache on their Node.js GraphQL server with little more than adding a piece of middleware to their GraphQL endpoint. This is ideal for applications that may not have been built from the ground up with a caching solution in mind. Simplicity does not mean sacrificing performance, however. By utilizing in-memory storage with Redis, a server running QLutch can retrieve cached data and respond to a client in fewer than 5 milliseconds. Developed under the tech accelerator, OS Labs (https://www.opensourcelabs.io).
