Creating a TikTok video downloader using Next.js would involve several steps, including getting the video URL, handling the user’s request, and then downloading the video to the server or allowing the user to download it.

Here’s an example of what the code might look like:

1. First, you would need to install the package “tiktok-scraper” by running the following command:

npm install tiktok-scraper

2. Next, you would create an API route in your Next.js application that handles the request to download a video.

import tikTokScraper from 'tiktok-scraper';
import { NextApiRequest, NextApiResponse } from 'next';

export default async (req: NextApiRequest, res: NextApiResponse) => {
    const { url } = req.query;
    const videoData = await tikTokScraper.getVideoMeta(url);
    const videoUrl = videoData.videoUrl;
    // handle the download
}

3. To handle the download you can use axios package or any other package to download the video, and then send it to the user as a response.

import axios from 'axios';

const downloadVideo = async (url, res) => {
    try {
        const video = await axios({
            url,
            method: 'GET',
            responseType: 'stream',
        });
        res.setHeader('Content-Disposition', 'attachment; filename="video.mp4"');
        res.setHeader('Content-Type', 'video/mp4');
        video.data.pipe(res);
    } catch (err) {
        console.error(err);
    }
}

It’s important to note that TikTok’s terms of service prohibit downloading videos without permission from the video owner, so you should always obtain the necessary rights before proceeding. Additionally, TikTok may change the URLs of their videos frequently, so this approach may not be reliable in the long term.
