How does Vue.js, Angular, or Ember do data store?

Ember has the library ember-data, which handles all relational data for you. It currently only works with REST-based apis ({json:api} being the best spec in REST for this), but it manages cache / requests / etc for you. No need to configure anything.

usage is this:

export default class MyComponent extends Component {
  @service store;

  async fetchUsers() {
    return await this.store.findAll('user');
  }
}

and then later down the road when you want to read from the cache, you can this.store.peekAll('user') for synchronous access to the cache

I have a lot of experience working with Vue.js. For state management in Vue js you can use Vuex (vuex.vuejs.org/guide/).
