ngx-translate with values in database?

I'm making an angular2 app using ngx-translate module

the service use .json documents to find the translations

first... i noticed that the local json documents route are "/src/assets/i18n/" like the next image:

so, the translate service use the default language to translate the diferents texts

this is how my app.component.ts works:

import { Component, OnInit, AfterContentInit } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';


@Component({
  selector: 'app-root',
  template: '<router-outlet></router-outlet>'
})
export class AppComponent implements OnInit {
  constructor(translate: TranslateService) {
    translate.addLangs(['es']);
    translate.setDefaultLang('es');

    const browserLang: string = translate.getBrowserLang();
    translate.use(browserLang.match(/en|es/) ? browserLang : 'es');
  }

  ngOnInit() {
  }

}

So the service use "en.json", "es.json" and "fr.json" to match the translation.

So my question is

How to avoid the "json" documents and match the texts with the text from the database?

So the client never have to been rebuild to get the new translation updates, just adding to the database and automatically translating without the rebuild
