Next-Cache-Handler

Introduction

@dbbs/next-cache-handler-core is designed to elevate the performance of Next.js applications by providing a robust caching solution that adapts to cookies, query parameters, and device types. This enables the delivery of content that is finely tuned to the context of each user, significantly improving load times and user experience.

Features

• Cache Segmentation: Dynamically segment cache storage based on cookies, query parameters, and device types.
• Multiple Storage Options: Supports various caching mechanisms including file system cache, in-memory cache, and Redis.
• Customizable: Flexible configuration options to tailor caching strategies to specific needs.

Quick Start

Installation

Ensure you have Node.js version 12 or higher installed.

npm i @dbbs/next-cache-handler-core
# or
yarn add @dbbs/next-cache-handler-core

Configuration

Create a cacheHandler.js in your project and configure as follows:

import { Cache, FileSystemCache } from '@dbbs/next-cache-handler-core'

Cache
    .setCacheStrategy(new FileSystemCache())
    .addCookies(['my-cookie-1','my-cookie-2'])
    .addQueries(['my-query-1','my-query-2'])
    .addDeviceSplit()
    // Additional configuration...
export default Cache    

Update your next.config.js to use the cache handler.

const nextConfig = {
    cacheHandler: require.resolve('./cacheHandler.js')
}

export default nextConfig

Cache Strategies

Explore various caching strategies to find the best fit for your application's needs:

• MemoryCache: Ideal for short-lived data in applications with limited cache size requirements. By default limit of size is set to 512MB.

import { Cache, MemoryCache } from '@dbbs/next-cache-handler-core'

Cache.setCacheStrategy(new MemoryCache())

import { Cache, MemoryCache } from '@dbbs/next-cache-handler-core'

// extending size limitation to 1024MB.
Cache.addStrategy(new MemoryCache({ sizeLimit: 1024 }))

• FileSystemCache: Suitable for persistent caching across application restarts.

import { Cache, FileSystemCache } from '@dbbs/next-cache-handler-core'

Cache.setCacheStrategy(new FileSystemCache())

• Redis: Perfect for distributed applications requiring shared cache access.

import { Cache } from '@dbbs/next-cache-handler-core'
import { RedisCache } from '@dbbs/next-cache-handler-redis'

// list of all accepted redis connection options.
const redisConnectionOpts = {
    url: 'redis://localhost:5843',
    ...
}

Cache.setCacheStrategy(new RedisCache(redisConnectionOpts))

• S3: Suitable for high scalable applications.

import { Cache } from '@dbbs/next-cache-handler-core'
import { S3Cache } from '@dbbs/next-cache-handler-s3'

Cache.setCacheStrategy(new S3Cache('cache-bucket-name'))

API Reference

addCookies

Cookie names what is going to be used to fragmentate cache based on browser cookies session.

Cache.addCookies(['my-cookie-to-split'])

addQueries

Query names to fragmentate cache based on url query parameters.

Cache.addQueries(['my-query-to-split'])

addDeviceSplit

Enables to fragmentate experience based on current User-Agent of the request.

Cache.addDeviceSplit()

setCacheStrategy

Applies given strategy to cache page data.

Cache.setCacheStrategy(new MemoryCache())

addNoCacheRoute

Add route to ignore cache list. All routes added here would be excluded from caching and will always render again.

Cache.addNoCacheRoute('/home')

Logging

Leverage the built-in logger for monitoring cache operations or integrate your custom logger for advanced logging capabilities.

import { BaseLogger, Cache, FileSystemCache } from '@dbbs/next-cache-handler-core'

class MyCustomLogger implements BaseLogger {
    constructor() {}

    info(data) {
        console.log(data)
    }

    error(data) {
        console.error(data)
    }
}

Cache.setCacheStrategy(new FileSystemCache).setLogger(new MyCustomLogger())
