I‘d say there has to be a check whether the active session user is allowed to update the user.

Why is it possible to update another users info with a different session?

Image of code using ComponentProps to extend HTML element props

When I need to extend React props of HTML elements, I use ComponentProps. Very convenient 😊

What is the best way to monitor performance without OTEL?

`vi.mock` Is a Footgun: Why `vi.spyOn` Should Be Your Default Which Vitest API is your favorite? There are so many great ones to choose from. test is a classic, vi.fn might have the best name, and expect is a great Swiss Army knife. Like a proud parent, I have…

Very in depth article about why you should favor spyOn instead of mock. Worth a read (and try). laconicwit.com/vi-mock-is-a...

new Date("wtf") How well do you know JavaScript's Date class?

11/28 with more luck than skill 😂 How much can you score?

At first I was skeptical, but after some time configuration via CSS variables felt very intuitive 😊

I wrote a blog post sophiebits.com/2025/07/21/t...

Thats sounds awesome! I vividly remember writing gulp tasks 😄

I'm starting to get a grep of how to handle CommonJS in an ESM Vite project. Nasty stuff 😄

IMHO creating PRs that big is disrespectful to reviewers. It‘s hard to effectively review so much at once and wastes my time..

Have fun! 😊

It has the following features:

- Prevent double submissions
- Error auto-referencing for A11y
- Simple field and form error display
- Button spinner based on submit status

Works like a charm 🚀

My guilty pleasure is creating perfect abstractions and component apis 😅 Really satisfied with my react-hook-form abstraction

It took me weeks to figure out that Hetzner blocks certain email ports for new accounts 🤦‍♂️

Selfish reasons for building accessible UIs All web developers know, at some level, that accessibility is important. But when push comes to shove, it can be hard to prioritize it above a bazillion other concerns when you’re trying to c…

'“eat your vegetables” is one of the least effective arguments in the world. [..]

I would like to list some of my personal, completely selfish reasons for building accessible UIs. No finger-wagging here: just good old hardheaded self-interest!'

The value of tests greatly increases when using AI for code generation. Let the AI check if it broke something by running the tests is so priceless 🚀

Claude Code suits my workflow much better than Cursor. It might be because I'm using Neovim 😅 The results are really impressive, but it's also quite slow and interrupts my workflow. I'll have to figure out the best way to integrate it 😊

One pattern I like to use is constants for time amounts with self-describing names. No need for extensive comments 🙅‍♂️

Are there any good guides on how to setup AWS SES properly? I manage to get it working, but not sure if everything is correct due to the massive amount of options 🙃 #AWS

Career advice for developers:

Write normal code. Just the basic good stuff. Don't be fancy, don't be clever. Don't use currying everywhere. You don't need Docker for everything. Also don't write dumb code. Please write good code. But make it normal. As unsurprising as possible.

Thank you

Not on my fun things to do list: handling DNS stuff 😅

Write flat tests. No "describe", no scenario nesting, no beforeEach/afterEach hooks (as a rule). Each test case is self-contained, listing all the setup it needs. Use Symbol.dispose for reliable cleanup. Use granular test cases.

☝️ These things will make your tests shine.

Great stack 🚀

What are your favorite battle tested technologies? 😊

I learned the hard way, that when importing a CommonJS package in an ESM app within the same monorepo, Vite requires different selectors for the package: optimizeDeps requires the package name and commonjsOptions requires a path. Wasted way too much time on this, but it finally works as expected 🙄

pnpm v10.12 is a huge release!

We’ve added many new features to the version catalogs system.

We also shipped a new experimental option that makes installation almost instant on most dev machines.

Finally 😍

Sexy! 😄

Whenever I implement basic features, such as authentication, for my starter kit, I like to check out the Laravel documentation. They're implemented and documented quite well there 🎯
