{"id":14912,"library":"serverless-offline-redis-server","title":"Serverless Offline Redis Server","description":"serverless-offline-redis-server is a Serverless Framework plugin designed to launch a local Redis server specifically for local development workflows using `serverless-offline`. The package, currently at version 0.0.2, integrates with the `serverless offline start` command to automatically manage a Redis instance alongside your serverless functions. Its primary differentiation lies in simplifying the setup of a local Redis instance within the Serverless Offline ecosystem, eliminating the need for manual Redis server management during development. It acts as a wrapper for the `redis-server` npm package, allowing users to configure Redis properties like port directly in their `serverless.yml`. The release cadence appears to be infrequent given its early version.","status":"active","version":"0.0.2","language":"javascript","source_language":"en","source_url":"https://github.com/apancutt/serverless-offline-redis-server","tags":["javascript","Serverless","Offline","Redis"],"install":[{"cmd":"npm install serverless-offline-redis-server","lang":"bash","label":"npm"},{"cmd":"yarn add serverless-offline-redis-server","lang":"bash","label":"yarn"},{"cmd":"pnpm add serverless-offline-redis-server","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"Peer dependency, required for plugin functionality within the Serverless Offline environment.","package":"serverless-offline","optional":false},{"reason":"This plugin requires the native Redis server executable to be installed locally on the development machine.","package":"Redis Server (native)","optional":false}],"imports":[{"note":"This package is a Serverless plugin and is integrated via the `plugins` section in `serverless.yml`, not through JavaScript `import` or `require` statements in application code.","wrong":"import { ServerlessOfflineRedisServer } from 'serverless-offline-redis-server'","symbol":"Plugin integration","correct":"plugins:\n    - serverless-offline-redis-server"},{"note":"Configuration for the Redis server is passed via the `custom.redis` property in `serverless.yml`, adhering to the options accepted by the underlying `redis-server` npm package.","wrong":"plugins:\n  serverless-offline-redis-server:\n    port: 8888","symbol":"Configuration","correct":"custom:\n  redis:\n    port: 8888\n    # ... other redis-server options"}],"quickstart":{"code":"npm install --save-dev serverless-offline-redis-server\n\n# Ensure Redis server is installed locally via your OS package manager (e.g., 'brew install redis' on macOS).\n\n# serverless.yml\nservice: my-redis-service\n\nplugins:\n  - serverless-offline\n  - serverless-offline-redis-server\n\ncustom:\n  redis:\n    port: 6379 # Default Redis port\n    bind: 127.0.0.1 # Bind to localhost\n    # Additional redis-server options can be added here\n\nprovider:\n  name: aws\n  runtime: nodejs18.x\n\nfunctions:\n  hello:\n    handler: handler.hello\n    events:\n      - http:\n          path: hello\n          method: get\n\n# handler.js (example usage)\nconst Redis = require('ioredis');\nconst redis = new Redis({ port: 6379, host: '127.0.0.1' });\n\nmodule.exports.hello = async (event) => {\n  await redis.set('mykey', 'myvalue');\n  const value = await redis.get('mykey');\n  return {\n    statusCode: 200,\n    body: JSON.stringify({ message: `Redis value: ${value}` }),\n  };\n};\n\n# To run:\nnpx serverless offline start","lang":"javascript","description":"This quickstart demonstrates how to install the plugin, configure it in `serverless.yml` to launch a local Redis server, and connect to it from a Serverless function during local development."},"warnings":[{"fix":"Ensure Redis server is installed and accessible in your system's PATH.
