redis-evalsha

Shavaluator wrapper around Redis EVALSHA/EVAL for efficient Lua script execution. Version 1.1.1 is latest (stable). Provides a simple API to pre-register Lua scripts with SHA-1 hashes, automatically falling back from EVALSHA to EVAL if the script is not cached on the Redis server. Avoids recomputing SHA-1 on every call (unlike node-redis's built-in eval). Designed for the node-redis client (mranney/node-redis). Lightweight: zero runtime dependencies. No TypeScript types.
