This little TypeScript utility scratches a very specific itch that anyone shipping image-heavy websites will recognize instantly: the tedious dance of optimizing images locally and then pushing them to object storage. assets-optimizer processes web project images and syncs them between local folders and Cloudflare R2, turning what is usually a manual multi-step chore into a single command.

What makes this repo interesting is how narrowly focused it is. Rather than being yet another sprawling asset pipeline that tries to replace your build tooling, it targets one specific workflow — the R2 sync loop — and does it in TypeScript so you can actually read the source and understand what's happening to your files. For teams that have adopted Cloudflare's ecosystem (R2 for storage, Workers for compute, Pages for hosting), tooling like this fills a real gap: the official R2 SDK gives you primitives, but not opinionated workflows.

Who would benefit?

• Solo developers and small teams running static sites or marketing pages on Cloudflare Pages who need to serve optimized images from R2 without a full CMS
• JAMstack devs who have outgrown throwing everything into a /public folder but don't want to adopt a heavyweight image CDN
• Anyone migrating off S3 to R2 who wants a script they can fork rather than an abstraction they have to trust

The fact that it's TypeScript rather than a shell script also means it's easy to extend — swap in different image processors, add WebP/AVIF variants, or wire it into a CI pipeline. Small utilities like this are exactly the kind of thing that quietly become indispensable in your package.json scripts once you discover them.
