@cognitiveproof/cawg-trqp-plugin-redis

Redis-backed DecisionCache and RevocationDeltaStore for cawg-trqp-refimpl, using ioredis.

Use this when running more than one instance of the verifier/HTTP service: the core package's default in-memory TTLCache and InMemoryRevocationDeltaStore only affect the single process they're constructed in, so cache hits and pushed revocation deltas don't propagate across instances. Backing both by Redis makes them shared across every instance.

Install

npm install @cognitiveproof/cawg-trqp-plugin-redis

Usage

import { Verifier, MockTRQPService } from "cawg-trqp-refimpl";
import { RedisDecisionCache, RedisRevocationDeltaStore } from "@cognitiveproof/cawg-trqp-plugin-redis";

const verifier = new Verifier({
  service: new MockTRQPService("data/policies.json", "data/revocations.json"),
  cache: new RedisDecisionCache({ url: process.env.REDIS_URL }),
  revocationDeltaStore: new RedisRevocationDeltaStore({ url: process.env.REDIS_URL }),
});

Or with HTTPTRQPService:

import { HTTPTRQPService, MockTRQPService } from "cawg-trqp-refimpl";
import { RedisDecisionCache } from "@cognitiveproof/cawg-trqp-plugin-redis";

const service = new HTTPTRQPService(new MockTRQPService("data/policies.json", "data/revocations.json"), {
  cache: new RedisDecisionCache(),
});

Configuration

Both classes accept an options object, or fall back to the REDIS_URL environment variable, or redis://localhost:6379:

new RedisDecisionCache({ url: "redis://my-redis:6379", keyPrefix: "myapp:cache:" });
new RedisRevocationDeltaStore({ url: "redis://my-redis:6379", key: "myapp:revocation-delta" });

Both share a single ioredis connection per process (see src/client.ts).
