Example

Example of a dummy translator. In your code, feel free to use HTTP requests to any urls.

class FakeTranslator {
	translate = (text, from, to) =>
		Promise.resolve(`FakeTranslator["${text}"-${from}-${to}]`);
	translateBatch = (texts, from, to) =>
		Promise.all(texts.map((text) => this.translate(text, from, to)));

	getLengthLimit = () => 4000;
	getRequestsTimeout = () => 300;
	checkLimitExceeding = () => -10000;

	static isSupportedAutoFrom = () => true;
	static getSupportedLanguages = () => ['en', 'ru', 'ja', 'de'];
}

FakeTranslator;
