⚛ React Conf 2025

📝 Note: If you are not interested in the articles fluff, scan the article read the bulleted, bold text and points that begin with emojis.

💡If you are responsible for implementing, architecting or greenlighting development using React, this post is for you. I dive deep into the economics of React to outline how expensive the free lunch of these open-source technologies might actually be.

Normally, I book one tech conference a year. Since I am usually paying out of pocket, I typically pick the event that most supports my personal interests.
Usually, Pycon US, the Python programming language's community conference is the heavy favorite. This year was no exception; I attended Pycon in Pittsburgh back in May and with that burned through my personal tech self-improvement budget.

Next.js client-only SPA example

Made this example to show how to use Next.js router for a 100% SPA (no JS server) app.

You use Next.js router like normally, but don't define getStaticProps and such. Instead you do client-only fetching with swr, react-query, or similar methods.

You can generate HTML fallback for the page if there's something meaningful to show before you "know" the params. (Remember, HTML is static, so it can't respond to dynamic query. But it can be different per route.)

Don't like Next? Here's how to do the same in Gatsby.
