Repository files navigation

A local-first file explorer making use of the new Origin Private File System (OPFS) and web workers.

Drop a folder of 1000+ images onto the page and it will generate a list of all the images and their EXIF data in a couple of seconds.

Demo coming soon (after work).

This is the base for a customiNaturalist upload interface.

Very much a work in progress.

• Remix (React)
• SST (AWS CDK)
• Comlink (Web Workers)
• IndexedDB

• OPFS (Origin Private File System)
• File System Access API
• Web Workers

• @tanstack/virtual (virtualized list)
• On-the-fly image compression using a web worker before rendering in the browser (single biggest perf gain).

TODO

• File tree directory navigation instead of a flat list. Would allow for separate sessions based off the directory.
• Experiment with different perf patterns (queues, better caching with IndexedDB + cache API, cancelable promises, async iterators etc.)
• Image Editing
• Ability to add GPS data to images with a GPX (or similar) file.
• Tests
• Run certain transformations in parallel depending on the number of cores available.

• Cleanup + consistent code style
• Responsive design
• Browser support

• Deployment pipeline with SEED
• Add privacy-focused analytics/error tracking (avoid session recordings etc.)

• Add to this README

• Add a license
• Add a contributing guide
