# Architecture
|
|
|
|
How `mangabaka-seeder` is built today. Update in the same commit as any structural change.
|
|
|
|
## Overview
|
|
The core (`src/core/`) is built and tested: `pipeline.ts` composes the stages of spec §3, `session.ts` holds the review state both front ends share. The server, page and userscript follow. The design is in [`specs/001-webtoons-covers.md`](specs/001-webtoons-covers.md):
|
|
one pure TypeScript core (`src/core/`) that turns a MangaBaka series link and a Webtoons series
|
|
link into a cover submission, used by three front ends — a static page served by a small
|
|
self-hosted Bun server (primary), a userscript, and later a Bun CLI. Replace this section with reality as modules land.
|
|
|
|
## Map (planned — spec §4)
|
|
| Path | Responsibility |
|
|
|---|---|
|
|
| `src/core/` | Pure pipeline: sources, Wayback history, image inspection, dedupe, seed, MangaBaka client. No DOM, Bun, Node or `GM_*` APIs. |
|
|
| `src/core/session.ts` | Review state shared by the page and the userscript: cards, main cover, rehosting, manual text, token flow (preview → confirm → save for review). |
|
|
| `src/web/` | Static page UI. |
|
|
| `src/server/` | Web-standard `fetch` handler (`app.ts`) run by `bun.ts` (`Bun.serve`, behind our reverse proxy). Static assets, `/api/fetch` allowlisted proxy, `/api/upload`, `/covers/*` from the storage folder (30-day sweep, total size cap). Gate and Workers entry deferred. |
|
|
| `src/userscript/` | Userscript on mangabaka.org; network via `GM_xmlhttpRequest`. |
|
|
| `src/cli/` | Later: Bun CLI. |
|
|
| `test/fixtures/` | Saved real responses; tests never hit the network. |
|
|
|
|
## Data flow
|
|
Links → series id + `source.resolve` → current + Wayback candidates → inspect (bytes, size,
|
|
sha256) → dedupe against MangaBaka → seed → user reviews → rehost (explicit) → submit or manual entry.
|
|
|
|
## External dependencies
|
|
| Service | Reached via | If unavailable |
|
|
|---|---|---|
|
|
| `api.mangabaka.org` | direct (CORS open) | Nothing works. |
|
|
| Webtoons HTML / `swebtoon-phinf.pstatic.net` | server proxy or `GM_xmlhttpRequest` | Nothing works. |
|
|
| Wayback (`web.archive.org`) | same | Warning; current covers only. |
|
|
| Server storage (folder on our server) | server | `server` host hidden; litterbox/catbox/direct still work. |
|
|
| litterbox / catbox | browser directly (litterbox), server or `GM_xmlhttpRequest` (catbox) | That host fails; others still work. |
|
|
|
|
## Invariants
|
|
- `src/core/` never imports from `web/`, `server/`, `userscript/` or `cli/`.
|
|
- The MangaBaka token is only ever sent to `api.mangabaka.org`, never through our server.
|
|
- The covers folder never exceeds `MBSEED_STORAGE_MAX_BYTES`; when full, uploads are refused and
|
|
no file is deleted before its 30 days.
|
|
- Nothing is uploaded or submitted without an explicit user action; saves use `save_mode: "review"`.
|
|
- `/api/fetch` only fetches allowlisted hosts; `/api/upload` only takes a source URL, never bytes.
