Hacker News Effect

Were it important, the author would have chosen a different medium.

"Something went wrong. Try reloading."

A few hours on top in Hacker News, we went from 3,000 visits/day to 300,000 visits/days. Lesson learned to survive a Hacker News storm:

- use a cheap VPS (our is 5€/month)

- make all your site static HTML: turns out HTML can be served really efficiently

- no server load: search is done in JavaScript in the browser (can be better though)

- cache every resource

Our VPS's CPU is 10% flat, RAM usage 20%

Bonus:

- be gracefull to users: minimum JavaScript, zero analytics in the browser

- begin to use WebP and Avif for images. Avif is really amazing!
