Quell is an easy-to-use, lightweight JavaScript library providing a client- and server-side caching solution and cache invalidation for GraphQL.

Quell is divided into two npm packages:

• Download @quell/client from npm in your terminal withnpm i @quell/client
• Download @quell/server from npm in your terminal withnpm i @quell/server

• IP-Rate Limiting to protect your server.
• Successfully handling cache mutations with cache invalidation.
• Quell/server offers optional depth and cost limiting middleware to protect your GraphQL endpoint! To use, please explore the@quell/server readme.
• Server-side cache now caches entire queries in instances where it is unable to cache individual datapoints.
• Client-side caching utilizing JavaScript's built in Map data structure.
• Client-side caching utilizing Least Recently Used (LRU) caching strategy.
• Server-side caching utilizing a configurable Redis in-memory data store with batching.
• Partial and exact match query caching.
• Programmatic rebuilding of GraphQL queries to fetch only the minimum data necessary to complete the response based upon current cache contents.
• A easy-to-use Chrome Developer Tools extension designed for Quell users. With this extension, users can:
  • Inspect and monitor the latency of client-side GraphQL/Quell requests.
  • Make and monitor the latency of GraphQL/Quell requests to a specified server endpoint.
  • View server-side cache data and contents, with the ability to manually clear the cache
  • Features require zero-to-minimal configuration and can work independently of@quell/client and@quell/server

• Currently, Quell can cache 1) query-type requests without variables or directives and 2) mutation-type requests (add, update, and delete) with cache invalidation implemented. Quell will still process other requests, but will not cache the responses.

Quell Developer Tool is currently available as a Chrome Developer Tools extension. The easiest way to get it is toadd it from the Chrome Web Store.
