03 / Portable media pipeline
YarReader
A portable media library that works without a server.
Primary capabilityOffline, recoverable media pipeline
What it is
A complete working system.
A browser-based reading experience backed by a crash-recoverable pipeline that converts mixed publication formats into a verified, self-contained offline library.
Why I built it
The engineering question.
Portable archives fail when readers depend on a database, a network, or fragile application state. YarReader pushes complexity into the build pipeline so the activated library stays ordinary, durable, and movable.
Engineering highlights
What the project demonstrates.
- CBZ, CBR, EPUB, PDF, and image adapters
- Content-addressed normalization
- Crash-recoverable transactions
- Immutable static exports with an offline reader

Overview first. Evidence when you want it.
The case study explains the architecture, boundaries, tradeoffs, and current state. The running application and repository provide the proof.
