    Here's how it's done ๐Ÿ‘€ 1. Create an image with multiple steps 2. Use CSS animations to step through each image Code and result ๐Ÿงต

    Another hot take: Your frontend should dictate your API not the backend. If you backend engineers are defining your API response data you're gonna have a bad time.

    hot take - When building an API - never start with the systems architecture. Start by designing the ideal syntax, and work your way backwards. DX and consumer ergonomics is the most important thing when it comes to API, library & frameworks design.

    All the jokes about OpenAI killing startups with each new release have some validity. We just removed Pinecone and Langchain from our codebase lowering our monthly fees and removing a lot of complexity. New Assistants API is fantastic โœจ

    For your stacked elements: Stop using border or box-shadow. Start using mask.

    Everything on fey.com is built by 2 engineers. The site, app, server, jobs, desktop, etc. I'm very proud of this.

    The laptop animation on feyapp.com is one Iโ€™m most proud of. The secret behind it is our <Sticky /> component that Iโ€™ve used everywhere for over 5 years now. Hereโ€™s how it works:

    Building a Stock Screener is incredibly complex. The amount of data you need is only half the equation. You also have to make it searchable and simple to use. Whatโ€™s the trick to ours?

    Building the dotted background for our charts is simpler than you'd imagine. It uses two CSS techniques and 4 lines of code.

    The reveal, height change, motion blur, selection... Was a joy to build and still a joy to use.
