💡 CSS Tip! In Anchor Positioning, you can use position-area to place an element relatively to its anchor, but there are 36 different positions !? 👀 No one can memorize them all, so I've created an interactive demo from where you can get the code. css-tip.com/position-area/

🧵 It's 3 AM. Your app is making the same API calls thousands of times. Rate limits are hitting. Timeouts everywhere. Your makeshift Map() cache is eating all your RAM. There's a better way. Let me show you how we got 550x faster responses with undici-cache-redis 👇

If you notice prettier-plugin-tailwindcss isn’t sorting tailwind classes correctly, it’s because starting from v4 you need to specify your CSS entry file. This was driving me crazy 😅

Como você lida com erros no Node.js? Se você só usa "throw new Error", pode estar deixando passar muita coisa já que não é possível diferenciar erros esperados dos não-esperados. Uma forma elegante pra iniciantes é nomear cada erro esperado e estender uma classe base 👇🏻

want to increase the click area without messing up your layout? try `:after` with `position: absolute` + `inset: -{value}px` this creates a larger, invisible hit area around the element, making it easier to click without changing the layout

📚 Got some questions around the `select` option lately: - How to make typed abstractions - How to make sure it doesn't run too often So per my own rules, I had to write a blogpost about it: tkdodo.eu/blog/react-query-s…
