Very short introduction

The best way is to read documentation, but there is an example below for a quick introduction.

If we want to select a user with its company and with the address of the company, in order that the final object would look like that:

const user = {
  id: '1',
  firstName: 'John',
  lastName: 'Smith',
  companyId: '1',
  company: {
    id: '1',
    name: 'Magic',
    adminId: '2',
    addressId: '1',
    address: {
      id: '1',
      street: 'Main st.',
      city: 'Town',
      country: 'Land',
    },
  },
};

We need to use a selector built by ngrx-entity-relationship for Redux or NGRX like that:

const selectUser = rootUser(
  relUserCompany(
    relCompanyAddress(),
  ),
);

Profit.
