Dynamically loading json file by package name (Typescript)

I am trying to write a small browser game in Typescript. So to start, I have a Scenario class that would need to load characters' dialogues based on scenario names. Here is how the Scenario class looks like:

export class Scenario extends Entity{

  public characters: Character[] = [];

  constructor(
    public readonly scenarionName: string,
    public readonly startDialogueId: string
  ) {
    super();
  }

  public awake() {
    this.loadCharacters();
  }

  private loadCharacters(){
    this.characters = [];
    // FIXME how can I dynamically load dialogues based on scenario name? 
  }
}

My idea was to have dialogues stored in JSON files, which would then be loaded based on the scenario name, which would also be a package name. Here how it looks:

enter image description here

In this case, I want to dynamically load 'npc.json' and 'player.json' into Scenario class based on the scenario name which in this case is a 'test'. In the future, there would be more scenarios and I would like to avoid hard coding. Can this be done in such a way and if so, how?

EDIT: the game would run in the browser.

Use fs module to get the file names in a directory and read the contents of the files.

import fs from('fs');

export class Scenario extends Entity{

  public characters: Character[] = [];

  constructor(
    public readonly scenarionName: string,
    public readonly startDialogueId: string,
    scenarioPath: string
  ) {
    super();
  }

  public awake() {
    this.loadCharacters();
  }

  private loadCharacters(){
    this.characters = [];
    const dialoguesDir = `${this.scenarioPath}/${this.scenarioName}/dialogues/`;
    let dialogueContent;
    fs.readdirSync(dialoguesDir).forEach(filePath => {
       dialogueContent = fs.readFileSync(`${dialoguesDir}${filePath}`).toString();
    // Do something with contents
    });
  }
}
