+Palett: **nextcloud collabora** — sex noder i samma lila, alla kopplade till **nc-collab-config** (kugghjul, inte flödesnod).

 `nc-collab-config` · `collabora-bridge` · `nc-office` · `collabora-convert` · `collabora-extract` · `collabora-transform` · `collabora-wopi`

+# Noder — nextcloud collabora
+
+Sex flödesnoder i paletten + en config. Alla sex pekar på samma **nc-collab-config** (kugghjul, inte i paletten). Utan config händer inget.
+
+## Backends
+
+| Backend | Typisk adress | Roll |
+|---------|---------------|------|
+| Nextcloud | `https://cloud.domain.name` | Filer (WebDAV) + Office-API (OCS) |
+| Collabora CODE | `https://172.17.0.2:9980` | Konvertering (`/cool/...`) på Docker bridge |
+
+Auth: **användarnamn + app-lösenord**. Inte kontolösen.
+
+Standardutdata om du inte anger sökväg: `/Dokument/OfficeOut/`
+
+---
+
+## Så hänger de ihop
+
+```
+nc-collab-config (URL + app-lösen)
+        │
+   ┌────┼────┬────────────┐
+   ▼    ▼    ▼            ▼
+collabora-*  nc-office  collabora-wopi  collabora-bridge
+(direkt CODE) (NC OCS)  (health/WOPI)   (kedjor + sparar)
+```
+
+**Tumregel**
+
+- PDF i Nextcloud → `collabora-bridge` **ncFileToPdf**
+- Fylla mall i NC → **fillTemplateSave** eller `nc-office template:fillFields`
+- Öppna i webbläsaren → `nc-office` **document:direct**
+- Bara byta format i minnet → `collabora-convert`
+- Se fältnamn → `collabora-extract` eller bridge **extractToPayload**
+- Kolla att CODE lever → `collabora-wopi` **capabilities**
+
+---
+
+## Gemensamma fält i msg
+
+| Fält | Betydelse |
+|------|-----------|
+| `ncPath` | Sökväg i användarens filer, t.ex. `/Dokument/avtal.docx` |
+| `fileId` | NC fil-id (slås upp från ncPath om saknas) |
+| `payload` | Rådata redan i flödet (Buffer eller HTML) |
+| `format` | pdf, png, docx, html, … |
+| `destNcPath` | Exakt målsökväg |
+| `destFolder` / `destName` | Mapp + namn (default `/Dokument/OfficeOut/`) |
+| `fields` / `transform` | JSON att skriva in i mall |
+| `templateNcPath` | Extra mall till convert |
+| `compareNcPath` | Gammal version för diff-PDF |
+| `operation` | Överstyr dropdown på noden |
+
+Fel → `msg.error` + röd nod. Flödet dör inte tyst.
+
+---
+
+## 1. collabora-convert
+
+Gör om fil till annat format via CODE. Sparar **inte** i Nextcloud — utdata i `msg.payload` (Buffer).
+
+**In:** `msg.payload` eller WebDAV GET `msg.ncPath`. Valfritt `templateNcPath`, `compareNcPath`, `format`.
+
+**Ut:** `payload`, `filename`, `format`, `contentType`, `statusCode`.
+
+```
+inject { ncPath: "/Dokument/avtal.docx", format: "pdf" }
+  → collabora-convert → debug
+```
+
+---
+
+## 2. collabora-extract
+
+Lista struktur (content controls, fält …). JSON ut, ingen fil.
+
+**In:** samma källa som convert. Filter: nod eller `msg.filter` (default `contentcontrol`).
+
+```
+inject { ncPath: "/Mallar/avtal.docx" }
+  → collabora-extract → function → collabora-transform
+```
+
+---
+
+## 3. collabora-transform
+
+Skriv värden i dokument via CODE. Kräver `msg.fields` eller `msg.transform`.
+
+```
+msg.ncPath = "/Mallar/avtal.docx"
+msg.fields = { "Kund": "AB Exempel", "Datum": "2026-08-22" }
+  → collabora-transform
+```
+
+Spara själv efteråt om filen ska ligga i NC.
+
+---
+
+## 4. collabora-wopi
+
+Hälsokoll och WOPI — inte konvertering.
+
+| Operation | Syfte |
+|-----------|--------|
+| `capabilities` | Första test att CODE svarar |
+| `discovery` | mime → editor-URL |
+| `buildEditor` | `wopiSrc` + `token` → `editorUrl` |
+| `checkFileInfo` / `getFile` | Felsökning |
+
+Publik editor-URL går via Nextcloud (`collaboraPublicUrl`), inte intern IP.
+
+---
+
+## 5. nc-office
+
+Nextcloud richdocuments OCS — mallar, fält, editor-URL, assets.
+
+| Operation | Kort |
+|-----------|------|
+| `templates:list` | Lista mallar |
+| `templates:create` | Ny fil från mall |
+| `template:extractFields` | Fält-JSON via NC |
+| `template:fillFields` | Fyll + spara i NC |
+| `document:direct` | `editorUrl` för inloggad användare |
+| `document:public` | Samma med shareToken |
+| `files:convert` | NC → NC konvertering |
+| `assets:create` | Infogningslänk till öppen editor |
+
+```
+inject { ncPath: "/Dokument/avtal.docx" }
+  → nc-office (document:direct) → debug editorUrl
+```
+
+---
+
+## 6. collabora-bridge
+
+Färdiga pipelines — det mesta i vardagsflöden.
+
+| Operation | Gör |
+|-----------|-----|
+| `ncFileToPdf` | NC-fil → PDF i OfficeOut |
+| `ncFileToPng` | Förhandsvisning |
+| `ncFileToHtml` | HTML-export |
+| `htmlToOffice` | HTML → docx/pdf … |
+| `fillTemplateSave` | Mall + fält → spara i NC |
+| `compareVersionsPdf` | Diff-PDF |
+| `extractToPayload` | Fält-JSON i msg |
+| `createAssetLink` | assetUrl |
+
+```
+inject { ncPath: "/Dokument/avtal.docx" }
+  → collabora-bridge (ncFileToPdf)
+  → debug destNcPath
+```
+
+Efter bridge kan du koppla dina befintliga OCS-noder (Talk, Mail, dela länk): först PDF i `/Dokument/OfficeOut/`, sedan dela.
+
+---
+
+## Config: nc-collab-config
+
+Skapas under kugghjul i Node-RED. Alla sex noder väljer samma config-instans.
+
+| Fält | Exempel |
+|------|---------|
+| nextcloudUrl | `https://cloud.domain.name` |
+| collaboraUrl | `https://172.17.0.2:9980` (bridge-IP, verifyTls=false) |
+| collaboraPublicUrl | `https://cloud.domain.name` |
+| username + app-lösenord | Nextcloud-inloggning |
+
+IP för CODE detekteras vid `./install.sh` — se `.env.example`.
