Redis storage backend for @pluckr/core
Readme
@pluckr/redis
Redis storage backend for @pluckr/core. Persists selector caches in Redis so repeated extractions skip the LLM entirely. Ideal for distributed deployments where multiple instances share the same cache.
Installation
npm install @pluckr/core @pluckr/redisUsage
import { Pluckr } from '@pluckr/core'
import { RedisStorage } from '@pluckr/redis'
import { anthropic } from '@ai-sdk/anthropic'
const pluckr = new Pluckr({
model: anthropic('claude-haiku-4-5-20251001'),
storage: new RedisStorage(), // defaults to localhost:6379
})
const result = await pluckr.extract({
html: '<html>...</html>',
schema: ProductSchema,
cacheKey: 'my-product-page',
})
await pluckr.close()Options
new RedisStorage({
url: 'redis://user:pass@host:6379', // connection URL
prefix: 'pluckr:', // key prefix (default)
ttl: 60 * 60 * 24, // expire after 24h (default: no expiry)
})BYO Redis instance
import Redis from 'ioredis'
const redis = new Redis({ host: 'cache.internal', port: 6379 })
const storage = new RedisStorage({ redis })
// close() is a no-op — you manage the connection lifecycleWhat it stores
Each cache entry is a JSON string stored at pluckr:{cacheKey}:{schemaHash}:
| Field | Description |
|-------|-------------|
| fieldMappings | CSS selectors + transforms for each schema field |
| consecutiveFailures | Failure count (triggers PERMANENT_FAILURE after 4) |
Clearing the cache
# All pluckr keys
redis-cli KEYS "pluckr:*" | xargs redis-cli DEL
# Specific key
redis-cli DEL "pluckr:my-product-page:abc123"License
