NodeJS script to remove 1000 DNS records added by Cloudflare when used * (wildcard) A record

index.js

// Now if you adding a domain with wildcard A record, Cloudflare uses strange scan, which added a 1000 trash domains (like 1-100, some english words like "ai", "air", "android").
// There's no way to bulk delete it, you can delete it only using their API.
// So I write a script that can help you with this problem.

// Discussions about same problem:
// https://community.cloudflare.com/t/delete-all-records-using-api/13410/2
// https://community.cloudflare.com/t/bulk-delete-dns-record/89540

const settings = {
    email: 'your@email',
    key: 'your_api_key',
    domain: 'domain.example'
}

const a = async () => {
    const cloudflare = require('cloudflare')({email: settings.email, key: settings.key});
    const zone_id = await cloudflare.zones.browse().then(zones => zones.result.find(x => x.name === settings.domain).id);
    const info = await cloudflare.dnsRecords.browse(zone_id).then(x => x.result_info);
    console.log(`Pages to delete: ${info.total_pages}`);
    for (let i=0;i<info.total_pages;i++) {
        const dns_records = await cloudflare.dnsRecords.browse(zone_id).then(x => x.result.map(dns_record => dns_record.id));
        await Promise.all(dns_records.map(id => cloudflare.dnsRecords.del(zone_id, id)));
        console.log(`Page ${i+1} is deleted remained ${info.total_pages-i} pages`);            
    }
