I'm implementing caching following the NestJS docs .

Create new project for this so there's no difference between docs example and this.

import { CacheModule, Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
@Module({
  imports: [CacheModule.register()],
  controllers: [AppController],
  providers: [AppService],
export class AppModule {}
Inject CacheManager..
import { CACHE_MANAGER, Controller, Get, Inject } from '@nestjs/common';
import { Cache } from 'cache-manager';
@Controller()
export class AppController {
  constructor(
    @Inject(CACHE_MANAGER) private cacheManager: Cache,
And use it
  @Get()
  async getHello(): Promise<string> {
    const value: string = await this.cacheManager.get('hello');
    if (value === null) {
      await this.cacheManager.set('hello', 'cache item', 60);
      return 'no cache exists';
    return value;
but I get this error, I don't know why:
TypeError: store.get is not a function
    at Object.get (.../node_modules/cache-manager/src/caching.ts:88:36)
    at AppController.getHello
This is a simple job, I think.
So there's no one seems to get this error (I looked it up).
I came across the same error and could not figure it out either.
node-cache-manager was only updated to version 5 within the last day.
https://github.com/node-cache-manager/node-cache-manager/tags
So I updated the package.json to use version 4.x
"cache-manager": "^4.0.0",
And now the caching works as expected.
Keep an eye on the package issue queue for further updates.
                To add onto this, the upgrade to v5 was a breaking change, and discussion about this specifically can be seen in this issue

Follow these steps to get it working on v5
Upgrade @nestjs/core, @nestjs/common and @nestjs/cli to use > 9.4.0
install @nesjs/cache-manager package
in your app.ts
import { CacheModule } from '@nestjs/cache-manager'; // not from "cache-manager"
add this
        CacheModule.register({
            isGlobal: true,
// if you use redis
            useFactory: async () => ({
                store: redisStore as any,
                host: config.REDIS_HOST,
                port: config.REDIS_PORT,
                // ttl: 1000,
NOTE: Don't use CacheModule.resgisterAsync
Run Your app and it should work fine
