A Node module with optional settings for validating HTML pages using the "validator.w3.org/nu" or "whatwg" standard.

const axios = require("axios").default;
const config = require("./config");
const filterData = require("./filter-data");

	const requestOptions = await config(options);
	const {ignore} = options;
	return new Promise((resolve, reject) => {
		axios(requestOptions).then((response) => {
			const { data, status } = response;
			if (data && status !== 200) {
				const error = new Error(`Validator returned unexpected statuscode: ${status}`);
				return reject(error);
			}
			return ignore ? resolve(filterData(data, ignore)) : resolve(data);
		}).catch((error) => {
			// To match the previous API
			const statusCode = error.message.replace(/^\D+/g, "");
			if (statusCode.length === 3) {
				return reject(new Error(`Validator returned unexpected statuscode: ${statusCode}`));
			}
			return reject(error);
		});
