Zeus Spec

To return the promise of type query for data object:

PROMISE_RETURNING_OBJECT = Chain.[OPERATION_NAME]({
    ...FUNCTION_FIELD_PARAMS
})(
    ...QUERY_OBJECT
).then ( RESPONSE_OBJECT => RESPONSE_OBJECT[OPERATION_FIELD] )

The simple command for object function params:

FUNCTION_FIELD_PARAMS = {
  KEY: VALUE
}

Query object:

QUERY_OBJECT = {
    ...RETURN_PARAMS
}

Return params is an object containing RETURN_KEY - true if it is a scalar, RETURN_PARAMS if type. Otherwise it is a function where you pass field params and type return params.

RETURN_PARAMS = {
    RETURN_KEY: true,
    RETURN_KEY: {
        ...RETURN_PARAMS
    },
    RETURN_FUNCTION_KEY:[
        {
            ...FUNCTION_FIELD_PARAMS
        },
        {
            ...RETURN_PARAMS
        }
    ]
}

Use Alias Spec

RETURN_PARAMS = {
  __alias: RETURN_PARAMS
}

Access aliased operation in a type-safe way:

PROMISE_RETURNING_OBJECT[ALIAS_STRING]
