I'M MORE PROUD OF THESE 128 KILOBYTES THAN ANYTHING I'VE BUILT SINCE

Summary from the TLDR Web Dev newsletter

This dev had to build a web application for users in Africa with poor internet infrastructure, mostly using feature phones with 240px screens and EDGE connections. They established strict constraints, including a 128KB total page budget, compatibility with Opera Mini browser, and responsive design from feature phones to 4K displays. Despite the extreme limitations, these tight constraints led to better solutions: they used system fonts instead of web fonts, built a minimal custom library called "Whizz" instead of heavy frameworks, and created an efficient AJAX-based navigation system that only loaded new page content rather than full page reloads.
