Axios Cache Wrapper for NestJS

api-nests.service.ts

import { HttpService } from '@nestjs/axios';
import { Injectable } from '@nestjs/common';
import {
  setupCache,
  buildMemoryStorage,
  defaultKeyGenerator,
} from 'axios-cache-interceptor';

@Injectable()
export class ApiService {
  constructor(private readonly httpService: HttpService) {}

  private readonly axiosCacheWrapper = setupCache(this.httpService.axiosRef, {
    storage: buildMemoryStorage(),
    generateKey: defaultKeyGenerator,
  });

  async getAxiosRequest() {
    const response = await this.axiosCacheWrapper.get(
      'https://example.com/wp/v2/keywords',
      {
        params: {},
        cache: {
          ttl: 1000 * 60 * 60, // 1 hour
          interpretHeader: false,
          methods: ['get'],
          cachePredicate: {
            statusCheck: (status) => status >= 200 && status < 400,
          },
        },
      },
    );

    return response.data;
  }
}

If you want to declare the wrapper in module class:

consts.ts

const AXIOS_CACHE_WRAPPER_TOKEN = 'AXIOS_CACHE_WRAPPER_TOKEN';

app.module.ts

  providers: [
    {
      provide: AXIOS_CACHE_WRAPPER_TOKEN,
      useFactory: (httpService: HttpService) => {
        return setupCache(httpService.axiosRef, {
          storage: buildMemoryStorage(),
          generateKey: defaultKeyGenerator,
        });
      },
      inject: [HttpService],
    },
  ],

app.service.ts

import { AxiosCacheInstance } from 'axios-cache-interceptor';

    @Inject(AXIOS_CACHE_WRAPPER_TOKEN)
    private readonly axiosCacheWrapper: AxiosCacheInstance,
