FakerLoader

Loads faker only when it is actually needed. This is useful for demo data, mocks, and development screens where you do not want to load the data generator in advance.

When to use

• When you need to generate test or demo data on demand.
• When you want to delay loading faker until the first real use.
• When you need to switch the generator locale for a specific scenario.

What it provides

• Controlled loading of a faker instance.
• Loading state and error state if something goes wrong.
• Access to the ready-to-use instance after a successful load.

Constructor parameters

• defaultLocale — Initial locale that will be used for loading faker.
• abortSignal — Stops the internal loading flow when the related lifecycle is aborted.

Public properties

• instance — The currently loaded faker instance for the active locale.
• isLoading — Shows whether the current locale is still loading.
• error — Returns the last loading error for the current locale.

Public methods

• load(locale?) — Loads faker for the provided locale or for the current default locale.
• destroy() — Cleans up the internal loader.

Usage example

import { createFakerLoader } from "mobx-swiss-knife";

const fakerLoader = createFakerLoader({
  defaultLocale: "en",
});

await fakerLoader.load();

const city = fakerLoader.instance.location.city();
const email = fakerLoader.instance.internet.email();

console.log(city, email);
