Ngx-translate and Ionic 3?

i have updated my language module and this worked for me, not sure if this is right way but it's worked.

import { NgModule } from '@angular/core';
import { IonicPageModule } from 'ionic-angular';
import { LanguagePage } from './language';
import { TranslateModule, TranslateLoader } from '@ngx-translate/core';
import { TranslateHttpLoader } from '@ngx-translate/http-loader';
import { HttpModule,Http } from '@angular/http';

export function createTranslateLoader(http: Http) {
  return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}

@NgModule({
  declarations: [
    LanguagePage,
  ],
  imports: [
    IonicPageModule.forChild(LanguagePage),
    TranslateModule.forChild({
            loader: {
                      provide: TranslateLoader,
                      useFactory: (createTranslateLoader),
                      deps: [Http]
                    }

        })
  ],
  exports: [
    LanguagePage
  ]
})
export class LanguagePageModule {}

i have added loader for child and export TranslateHttpLoader in language.module.ts

language.ts

langselect(form: NgForm){
  	let langselcode = this.langform.value.langcode;
  	this.storage.set('AppLangcode', langselcode);
  	this.translate.use(langselcode);
  }
