Another take on the problem of fetch() sometimes returning a response and sometimes throwing an error: what if it always returned an object containing either response or error?

Did you know that fetch() can reject errors? Network errors or AbortSignals cause errors, so you never get a Response object and need to handle these separately. That's annoying so I created Safe Fetch, a wrapper that always returns a Response:

This is super weird. When I test Bredbox locally, it's able to correctly fetch and extract meta data from a YouTube URL. Once deployed to Cloudflare, I get nothing. (thinking emoji)

I currently have three VS Code windows open:
1. My local file system
2. My WSL instance
3. A remote server via SSH
It's nearly impossible to tell the difference between them. Amazing work by the VS Code team.

While I generally enjoy using Cloudflare infrastructure, the worker subrequests limit is a pain to work with. Very little visibility into what counts as a subrequest and the limits aren’t enforced locally so it’s a huge time sink to debug “too many subrequests” errors.

Pro tip: Did you accidentally `rm` a file you had open in this VS Code session? Open the command palette --> "Local History: Find Entry to Restore".
You're welcome.

One of the hidden benefits of ESLint going multi-language is pulling in a new group of contributors. Since releasing the JSON, CSS, and Markdown plugins, we had over a dozen new consistent contributors and four became team members.

I still use ChatGPT for most non-coding AI stuff. I feel like it always give the right level of detail. With Claude, it's like that friend who you ask what time it is and they tell you the history of timepieces.

Pretty excited that full-text search just shipped on Bredbox! Feature parity with Pocket for managing bookmarks is getting very close. Only major feature left to implement is highlights.

If you want your open source project to grow, you need to get comfortable with other people reviewing and merging pull requests without your involvement. This didn't come naturally to me and still feels weird, but there's no other way to keep up project velocity.

Early thoughts on Claude Haiku 4.5: It seems just as fast as GPT-4.1 but with more agency and more capacity to understand complex situations. It has less of a tendency to go off on tangents than Sonnet 4.0 but still does from time to time.

My current biggest time sink is Supabase's lack of true down migrations. `migration down` deletes all data, which essentially is like doing `db reset`.
