Insights From A Spring Boot Leisure Project for Everyday Developer Life
summary
Builds a Spring Boot service that accepts Telegram images, resizes them with imgscalr, and forwards PNGs to a reverse‑engineered GraphQL API discovered by decompiling the APK with APKLab and unpinning TLS in about ten minutes, proxying traffic through Postman. Packages with Spring Boot Buildpacks, pushes images via GitHub Actions, and auto‑updates with Watchtower on a home NAS. Hits: emoji fonts missing in containers (two nights to fix by adding Google Noto), and the private API breaks without warning.
