FeathersJS custom API method that retrieves enum Type, to fill a Dropdown in React

Question

So I'm trying to fill a select component with a enum type from mongoose

In my user service the schema looks something like :

firstName: { type:String, required: true },
   ...
ris:{type: String, default: 'R', enum:['R', 'I', 'S']},

In my feathers service I can access the Model with "this.Model"

so in any hook I can do:

this.Model.schema.path('ris').enumValues); //['R','C','I']

and I get the values from the enum type.

Now since I can't create custom API methods other that the officials ones

• Feathers calling custom API method
• https://docs.feathersjs.com/clients/readme.html#caveats
• https://docs.feathersjs.com/help/faq.html#can-i-expose-custom-service-methods

How can I create a service method/call/something so that I can call it in my

componentDidMount(){ var optns= this.props.getMyEnumsFromFeathers}

and have the enum ['R','C','I'] to setup my dropdown

I'm Using React/Redux/ReduxSaga-FeathersJS

I'd create a service for listing Enums in the find method:

class EnumService {
  find(params) {
    const { service, path } = params.query;
    const values = this.app.service(service).Model.schema.path(path).enumValues;

    return Promise.resolve(values);
  }

  setup(app) {
    this.app = app;
  }
}

app.use('/enums', new EnumService())

Then on the client you can do

app.service('enums').find({ query: {
    service: 'myservice',
    path: 'ris'
  }
}).then(value => console.log('Got ', values));
