insertMany

lets add getCountry functions:

Example 
    
  const addMultipleCountriesValidator = () => {
    return object({
      set: object({ multiCountries: array(object()) }),
      get: coreApp.schemas.selectStruct("country", { users: 1 }),
    });
  };
  const addCountries: ActFn = async (body) => {
    const { multiCountries } = body.details.set;
      

        return await countries.insertMany({
            docs: multiCountries,
            projection: body.details.get,
        });
      

  };
  coreApp.acts.setAct({
    schema: "country",
    actName: "addCountries",
    validator: addMultipleCountriesValidator(),
    fn: addCountries,
  });

insertMany functions accept three inputs:

The code

So this is all the code we've written so far (You can also see and download this code from here):

Return Of Example: 
    
      {
        body: [
