@eleven-labs/nest-profiler-cache

@eleven-labs/nest-profiler-cache intercepts @nestjs/cache-manager operations (GET HIT, GET MISS, SET, DEL) during a profiled execution and displays them in a Cache panel with hit/miss statistics.

Installation

pnpm add @eleven-labs/nest-profiler-cache @nestjs/cache-manager

Peer dependencies: @nestjs/cache-manager ^3.0.0

Setup

import { CacheModule } from '@nestjs/cache-manager';
import { CacheCollectorModule } from '@eleven-labs/nest-profiler-cache';

@Module({
  imports: [
    CacheModule.register({ isGlobal: true }),
    CacheCollectorModule.forRoot(),
    ProfilerModule.forRoot({ isGlobal: true }),
  ],
})
export class AppModule {}

What it collects

For each cache operation:

The panel also displays an aggregated hit/miss ratio.

Toolbar badge

{hits}H/{misses}M (e.g., 8H/2M). When no GET operations: {n}ops.

How it works

At module initialization, the collector wraps the CACHE_MANAGER's get, set, and del methods using a JavaScript Proxy. Each wrapped call records the operation type, key, and duration into the current request profile.
