Aspect	Advantages	Drawbacks / Mitigations
Single tsconfig	One TS project → imports @/backend/... & @/frontend/... just work.	Adonis needs slightly looser TS settings (es2022 libs, node types) than the PWA; solve with tsconfig.backend.json extending the root config. Vite still uses root.
No package duplication	Keep one package.json / yarn.lock; dedupe devDeps.	Adonis’s CLI expects its own dependencies. Prefix backend‐only deps with /* backend */ comment to keep clarity or move them to dependencies.
Simple import paths	import { set } from "@/api/models/set" works both sides.	Must avoid importing browser-only libs in backend folders; TypeScript path aliases + ESLint plugin “no-browser-imports” for /backend.
Shared scripts	npm run dev:full can concurrently start node ace serve --watch and vite.	Vite & Adonis both watch; heavy CPU while both build – mitigated by esbuild + polling off.
CI/CD	One pipeline.	Back-end & front-end tests intermixed; use “tags” in Vitest/Japa configs.
Adonis folder re-map	.adonisrc.json: { "directories": { "app": "../../src/backend", "config": "../../config" }}. Works fine.	Ace generators generate files in mapped folder; ok.
