sidekick.js is a ServiceWorker that automatically batches individual Solana JSON RPC requests without requiring you to change your existing code.
There are a lot of caveats and will be some open questions. I can almost guarantee you it's not production-ready yet.
- Compatible with any JS frontend framework, or lack thereof
- Simple as possible to install and update, ideally requiring no or very little existing code changes
- Provide sensible defaults, offering granular configuration and easy overrides
Based off https://github.com/johnrees/rate-limited-fetch-service-worker which is no longer needed because either RPCs aren't incorrectly sending CORS errors when rate limiting anymore, or web3.js is now retrying on CORS errors (I haven't checked recently). More info
