You can use your own fetcher, for example, fetch through a real browser.

`typescript
import { LeetCode, fetcher } from 'leetcode-query';
import { chromium } from 'playwright-extra';
import stealth from 'puppeteer-extra-plugin-stealth';

// setup browser
const _browser = chromium.use(stealth()).launch();
const _page = _browser
.then((browser) => browser.newPage())
.then(async (page) => {
await page.goto('https://leetcode.com');
return page;
});

// use a custom fetcher
fetcher.set(async (...args) => {
const page = await _page;

const res = await page.evaluate(async (args) => {
const res = await fetch(...args);
return {
body: await res.text(),
status: res.status,
statusText: res.statusText,
headers: Object.fromEntries(res.headers),
};
}, args);

return new Response(res.body, res);
});

// use as normal
const lc = new LeetCode();
const daily = await lc.daily();
console.log(daily);
await _browser.then((browser) => browser.close());
