slicy - image resizer

a queue based image resizing tool, built for speed ⚡️

---

tech stack

• bun – runtime (blazingly fast)
• hono – backend framework
• bullmq – job queue
• sharp – image resizing + webp conversion
• redis – job storage
• react – frontend

---

how it works

you upload an image → it gets queued → resized into multiple sizes → saved as .webp → served to you via urls.

the flow

1. upload – image hits the backend
2. queue – job added to bullmq
3. process – sharp resizes it in the background
4. store – saved to public/images/<jobId>
5. respond – returns urls of resized images

you probably dont even need to read any further - becuz images tell you everything

---

features

• multiple sizes – customize resize steps (90px, 120px, etc.)
• async processing – doesn't block anything
• served as static – use the URLs anywhere

---

why it slaps

• bun makes it ridiculously fast
• sharp is memory efficient

---

run it

requires macOS (uses brew in entrypoint.sh, tweak for other OS)

before running, make sure you install deps:

cd ui && bun install
cd ../backend && bun install

then start it up:

./entrypoint.sh

spins up redis → backend → frontend
you’re live. go throw some images in! 😎
