Verifying Clerk JWTs in Cloudflare Workers
Authentication typically happens in one of two places: the frontend checks if a user is logged in before showing protected UI, and the backend validates tokens before processing requests. There's a third option—verifying JWTs at the edge, in a Cloudflare Worker, before requests reach your backend infrastructure. This approach rejects unauthenticated requests at the edge, preventing them from consuming backend resources. It keeps your authentication provider's secrets out of your backend infras
Securing API Keys with AWS Secrets Manager and Cloudflare Workers
API keys for backend authentication create a fundamental challenge in web applications: the credentials need to authenticate requests but cannot be exposed to clients. Hardcoding keys in frontend bundles or environment variables leaves them visible in browser developer tools. Anyone who opens the network tab can extract the key and make unauthorized requests. Static configuration files require manual rotation and create operational risk—when a key needs to change, someone has to remember to upda
Securing AWS S3 with Cloudflare: The Worker Direct Fetch Pattern
When building a React SPA with Cloudflare as the CDN it is possible to use S3 for static asset storage. If you have all of your resources typically on AWS, but want some of the advantages of Cloudflare, you can build a system that is very similar to the traditional Cloudfront + S3 architecture. There are a few differences in deployments and setup, but it is generally the same. The typical approach with Cloudflare uses S3 static website hosting with IP restrictions, but this comes with significan

Analyzing the domains (and sites) of an authoritarian regime
If you've ever wondered what domains the US federal government has registered, there's a rather exhaustive list over in the dotgov-data repository on GitHub, which is maintained by CISA . You can see the raw CSV here . They don't include the registration date, but you can derive that from public WHOIS records or by examining the repository's git histor

Benchmarking Cloudflare R2 HEAD Requests from Cloudflare Workers
Why would I do this? For my latest project, mapvoyage, I need to serve text files (wikitext to be specific), directly to the user if possible, as well as in a separate function select one wikitext file to display from a list of wikidata ids that may or may not have an associated wikitext file. Latency is important and I'd like the data to be edge-available if possible. R2 with workers seemed ideal here, as the client can download the files from R2 directly and I can lookup the urls from a separate worker, which hopefully shouldn't have a long latency for reading them.
How to use Cloudflare Warp with a UDM Pro

It supports various operating systems, including Windows, Linux, Mac, iOS, and Android.

DNS records and a Cloudflare security violation
This site (was) hosted on Cloudflare Pages. In an effort to make scheduling more convenient for my mentee from Underdog Devs , I set up SavvyCal . Without giving it any thought, I added an easy to remember CNAME and pointed it at SavvyCal.
Colocating your code and your Cloudflare Workers
When I first moved my site to Cloudflare, I kept all of my Cloudflare Workers in their own repositories. I wanted to keep my account and zone IDs secret, but wasn't sure how best to do so. So there they sat cozy (but lonely) in their own repositories with their secrets of questionable value.
Syndicating an RSS feed to Mastodon using a Cloudflare worker
Everything shared from my site to Mastodon runs out of a single all activity RSS feed. You're welcome to subscribe to it, but it's formatted with social syndication in mind — emojis, hashtags and truncation that match that use case. This feed is populated from a fairly verbose processContent collection. It also populates my sitemap and search index since there's plenty of overlap in format and the data being handled. Anyways.
