{"id":11920,"library":"redis-server","title":"Redis Server Manager","description":"This `redis-server` package, currently at version 1.2.2 (last published June 2018), provides a programmatic interface to start and stop a local Redis server instance within Node.js applications. It's primarily intended for testing or local development environments, simplifying the lifecycle management of a Redis process from within Node.js. The package acts as a wrapper for the native `redis-server` executable, requiring it to be pre-installed on the system or a custom path provided in the configuration. Due to its age and lack of recent updates, it primarily supports CommonJS and older Node.js versions, lacking modern ESM support and potentially having compatibility issues with newer Node.js runtime features. There is no active development, marking it as an abandoned package.","status":"abandoned","version":"1.2.2","language":"javascript","source_language":"en","source_url":"https://github.com/BrandonZacharie/node-redis-server","tags":["javascript","Redis","server","manager"],"install":[{"cmd":"npm install redis-server","lang":"bash","label":"npm"},{"cmd":"yarn add redis-server","lang":"bash","label":"yarn"},{"cmd":"pnpm add redis-server","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"This package is a wrapper around the native Redis server executable.
