ORM selectors for redux, @ngrx/entity and @ngrx/data. Ease of relationships with entities.

Package Exports

  • ngrx-entity-relationship
  • ngrx-entity-relationship/bundles/ngrx-entity-relationship.umd.js
  • ngrx-entity-relationship/fesm2015/ngrx-entity-relationship.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ngrx-entity-relationship) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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.
