Building a Zero-Framework, Local-First PWA to Combat Web Bloat
Stephen Sebastian developed QuickConvertUnits, a lightweight, ad-free Progressive Web App designed to provide fast unit conversions without the bloat of traditional web calculators. Built with native HTML5, CSS, and vanilla JavaScript, the app operates entirely offline using service workers and prioritizes user privacy with no backend or tracking. The project emphasizes performance, minimalism, and efficient use of modern browser capabilities.
- ▪QuickConvertUnits is a zero-framework, local-first PWA for unit conversion that runs completely offline.
- ▪The app uses native web APIs, avoiding external libraries or frameworks to maintain speed and privacy.
- ▪It supports multiple languages through a lightweight JSON-based i18n system without increasing initial load size.
- ▪No user data is sent to servers, and all calculations are performed client-side for instant results.
- ▪The developer invites feedback on handling floating-point precision in JavaScript without heavy math libraries.
