I shipped 29 browser-only image tools. These 5 boring patterns kept the codebase sane
Zihang Dong discusses the development of 29 browser-only image tools, highlighting the challenges faced during the process. He emphasizes the importance of maintaining a consistent codebase and user experience across all tools. The article outlines five effective patterns that helped streamline the development and ensure efficiency.
- ▪The toolkit is built using static HTML, ES2020 JavaScript, and Canvas, with no backend processing or uploads.
- ▪A shared dispatcher was implemented to avoid duplicated logic across tools, simplifying maintenance.
- ▪Expensive decoders are lazy-loaded only when necessary, preventing unnecessary load on the homepage.
