Utilizing memoizee in TypeScript's object-oriented programming

Implementing memoization in TypeScript classes using the memoizee library is something I would like to explore.

Below is some code showcasing my initial attempts:

import memoize from "memoizee"
import { getModule, Module, MutationAction, VuexModule } from "vuex-module-decorators"
import store from "@/store"
import { User } from "./models"
import { UserAPI } from "./api"

@Module({ namespaced: true, name: "user", store, dynamic: true })
class UserModule extends VuexModule {
  user: User | null = null
  getUser = memoize(UserAPI.getUser, { maxAge: 10 * 60 * 1000, promise: true })

  @MutationAction
  async fetchProfile() {
    const user = await this.getUser()
    return { user }
  }
}

export default getModule(UserModule)

However, an error occurs stating that

TypeError: this.getUser is not a function
. What could be causing this issue? How can I correct it and effectively utilize memoizee in TypeScript's classes?

Answer №1

If you're encountering issues with importing memoize, try a different approach.

Check out the method that resolved it for me:

import * as memoizee from 'memoizee';
