Payload Redis Cache Plugin

This is a modified version of this plugin for Payload CMS that solved a particular use case I have

This plugin for Payload CMS adds a cache layer to API endpoints. The cache is based on the combination of the user's collection and the original URL.

Requirements

Payload version 1.0.19 or higher is required
A Redis instance is required

Installation

To install the plugin, run one of the following commands:

yarn add @aengz/payload-redis-cache

npm install @aengz/payload-redis-cache

Redis package

You also need to install the redis package if it is not already installed:

yarn add redis

npm install redis

Usage

To use the plugin, add it to the Payload config as follows:

import { buildConfig } from 'payload/config';
import { cachePlugin } from '@aengz/payload-redis-cache'

const config = buildConfig({
  // your config here
  
  plugins: [
    cachePlugin({ 
      excludedCollections: ['users'],
      //  excludedGlobals: ['myglobal']
    })
  ]
})

Add the initializer function in server.ts

import { cachePlugin } from '@aengz/payload-redis-cache'

...

initRedis({
  redisUrl: process.env.REDIS_URI
})
