Redis Array Playground

Tool: Redis Array Playground Salvatore Sanfilippo submitted a PR adding a new data type - arrays - to Redis. The new commands are ARCOUNT , ARDEL , ARDELRANGE , ARGET , ARGETRANGE , ARGREP , ARINFO , ARINSERT , ARLASTITEMS , ARLEN , ARMGET , ARMSET , ARNEXT , AROP , ARRING , ARSCAN , ARSEEK , ARSET . The implementation is currently available in a branch, so I had Claude Code for web build this interactive playground for trying out the new commands in a WASM-compiled build of a subset of Redis running in the browser. The most interesting new command is ARGREP which can run a server-side grep against a range of values in the array using the newly vendored TRE regex library . Salvatore wrote more about the AI-assisted development process for the array type in Redis array type: short story of a long development .
