ZenStack Cache

Reduce response times and database load with query-level caching integrated with the ZenStack ORM.

NPM VersionNPM DownloadsBuild StatusJoin the ZenStack Cache channelLicense: MIT

ℹ️ This project is not affiliated with or endorsed by the ZenStack team.

Features

  • 🌐 Redis Cache: A central cache to scale across different systems.
  • 🖥️ Memory Cache: A simple cache when scale is not a concern.
  • 🛟 Type-safety: The caching options appear in the intellisense for all read queries.
  • 🏷️ Tag-based Invalidation: Easily invalidate multiple related cache entries.

Requirements

  • ZenStack (version >= 3.3.0)
  • Node.js (version >= 20.0.0)
  • Redis (version >= 7.0.0)
    • ℹ️ Only if you intend to use the RedisCacheProvider

Installation

npm install @visualbravo/zenstack-cache
pnpm add @visualbravo/zenstack-cache
bun add @visualbravo/zenstack-cache

Sample Usage

import{schema}from'./zenstack/schema'import{ZenStackClient}from'@zenstackhq/orm'import{defineCachePlugin}from'@visualbravo/zenstack-cache'import{RedisCacheProvider}from'@visualbravo/zenstack-cache/providers/redis'import{MemoryCacheProvider}from'@visualbravo/zenstack-cache/providers/memory'constclient=newZenStackClient(schema,{dialect: ...,}).$use(defineCachePlugin({// Choose only one provider.// 1️⃣provider: newRedisCacheProvider({url: process.env['REDIS_URL'],}),// 2️⃣provider: newMemoryCacheProvider(),}),)asyncfunctiongetPostsPublishedByUser(userId: string){constpublishedPosts=awaitclient.post.findMany({where: {published: true,authorId: userId,},// All of these are optional.cache: {ttl: 60,swr: 120,tags: [`user:${userId}`],},})returnpublishedPosts}

Invalidation

You can easily invalidate multiple cache entries.

// Invalidate specific tags.awaitclient.$cache.invalidate({tags: ['user:1'],})// Invalidate everything.awaitclient.$cache.invalidateAll()

Cache Status

After performing a query, you can check where the result came from.

constpublishedPostsStatus=client.$cache.status// 'hit' | 'miss' | 'stale'
  • hit - a cache entry in the ttl window was found, and the database was not queried.
  • miss - a cache entry was not found, and the database was queried.
  • stale - a cache entry in the swr window was found, and the database was queried in the background to revalidate it.

Revalidation

If the result was stale, you can choose to await its revalidation.

constrevalidatedPublishedPosts=awaitclient.$cache.revalidationasPost[]

Cache Options

  • ttl reduces response times and database load by serving cached results.
  • swr reduces response times by serving cached results, but does not reduce database load because it performs a revalidation in the background after each request.

Note

The total TTL of a cache entry is equal to its ttl + swr. The ttl window comes first, followed by the swr window. You can combine the two options to best suit the needs of your application.

Caching Forever

You can cache results forever by specifying neither ttl nor swr. Such results will always be considered fresh.

awaitclient.post.findMany({cache: {tags: [`user:${userId}`],},})

Warning

Your server may eventually run out of memory if you're not careful about invalidating entries that never expire.

  • hit - a cache entry in the ttl window was found, and the database was not queried.
  • miss - a cache entry was not found, and the database was queried.
  • stale - a cache entry in the swr window was found, and the database was queried in the background to revalidate it.
Revalidation
If the result was stale, you can choose to await its revalidation.
constrevalidatedPublishedPosts=awaitclient.$cache.revalidationasPost[]
Cache Options
  • ttl reduces response times and database load by serving cached results.
  • swr reduces response times by serving cached results, but does not reduce database load because it performs a revalidation in the background after each request.
Note
The total TTL of a cache entry is equal to its ttl + swr. The ttl window comes first, followed by the swr window. You can combine the two options to best suit the needs of your application.
Caching Forever
You can cache results forever by specifying neither ttl nor swr. Such results will always be considered fresh.
awaitclient.post.findMany({cache: {tags: [`user:${userId}`],},})
Warning
Your server may eventually run out of memory if you're not careful about invalidating entries that never expire.

ZenStack Cache

Reduce response times and database load with query-level caching integrated with the ZenStack ORM.
NPM VersionNPM DownloadsBuild StatusJoin the ZenStack Cache channelLicense: MIT

ℹ️ This project is not affiliated with or endorsed by the ZenStack team.

Features
  • 🌐 Redis Cache: A central cache to scale across different systems.
  • 🖥️ Memory Cache: A simple cache when scale is not a concern.
  • 🛟 Type-safety: The caching options appear in the intellisense for all read queries.
  • 🏷️ Tag-based Invalidation: Easily invalidate multiple related cache entries.
Requirements
  • ZenStack (version >= 3.3.0)
  • Node.js (version >= 20.0.0)
  • Redis (version >= 7.0.0)

    • ℹ️ Only if you intend to use the RedisCacheProvider
Installation
npm install @visualbravo/zenstack-cache
pnpm add @visualbravo/zenstack-cache
bun add @visualbravo/zenstack-cache
Sample Usage

Invalidation
You can easily invalidate multiple cache entries.
// Invalidate specific tags.awaitclient.$cache.invalidate({tags: ['user:1'],})// Invalidate everything.awaitclient.$cache.invalidateAll()

  • hit - a cache entry in the ttl window was found, and the database was not queried.
