Use Custom Fetcher

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

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());
