如何更改我的"language.json“文件(键和值)而不必重新编译angular应用程序？

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})
export class LanguageService {
  private languageUrl = 'assets/language.json';

  constructor(private http: HttpClient) { }

  getLanguageData() {
    return this.http.get(this.languageUrl);
  }
}

import { Component, OnInit } from '@angular/core';
import { LanguageService } from 'path-to-language.service';

@Component({
  selector: 'app-example',
  templateUrl: './example.component.html',
  styleUrls: ['./example.component.css']
})
export class ExampleComponent implements OnInit {
  languageData: any;

  constructor(private languageService: LanguageService) { }

  ngOnInit() {
    this.languageService.getLanguageData().subscribe(data => {
      this.languageData = data;
    });
  }
}

<p>{{ languageData.key }}</p>
