npm package: @node-red-tools/node-red-contrib-redis
Description: Node Red client for Redis with pub/sub, list, lua scripting  and other commands support.
Author: Andre Alexandre Avila
Latest version: 1.0.1

# node-red-contrib-redis
Node Red client for Redis with pub/sub, list, lua scripting, ssl, cluster, custom commands, instance injection and other commands support.

Now uses same connection per flow and open new if you set block connection option.

Roadmap:
- (partial via instance injection)Stream Support
- (ok)Flow or Global redis instance injection to use on function Node.
- (wip)Better Validations
- (instance injection)Custom Commands support(Modules)

See the Sample flow before ask how this module works.

Please test and make feedback.
