# Dashboard App — Agent Reference Guide

## Overview

`apps/dashboard` is the primary Angular (NgModule-based) frontend for Nuclia's ARAG platform. Lets users manage Knowledge Boxes (KBs) and Retrieval Agents (ARAGs), upload resources, monitor usage, configure AI models, and interact with Nuclia's search/RAG capabilities.

**Entry point:** `main.ts` → `AppModule` → `AppComponent`  
All ARAG workflow code lives in `libs/common` and is shared with `apps/rao`.

## Core Modules

### `AppModule`

`STFConfigModule.forRoot(environment)`, `TranslateModule.forRoot(MultiTranslateHttpLoader)`, `BaseModule`, `PaToastModule`, `AuthInterceptor`, `TitleStrategy → AppTitleStrategy`.

### `KnowledgeBoxModule`

`KnowledgeBoxComponent` (thin router-outlet wrapper) + `KnowledgeBoxHomeComponent` (KB dashboard: usage charts, status counts, trial info, REMI metrics) + `SimplePageModule` (lazy, at `/simple`, gated by `unstable.simpleUI` feature flag). `SimplePageComponent` (inside `SimplePageModule`) routes to `ReaderExperienceComponent` for read-only KB users or `SimpleKBComponent` for admins/contributors.

---

## Knowledge Box Home

`KnowledgeBoxHomeComponent` shows: KB endpoint URL, UID, region, status badge, 4 usage charts (Processing/Search/Ask/Nuclia Tokens), REMI metrics (if `authorized.remiMetrics`), resource status counts, trial info.

---

## ARAG Dashboard (in `libs/common`)

`AgentDashboardComponent` is the ARAG workflow editor — shared with `apps/rao`.

**`WorkflowService`** orchestrates the canvas:

- Dynamically creates node form components via `createComponent()` + `ApplicationRef.attachView()`.
- Sidebar panels (rules, add-node, test, import, export) are rendered this way — **no `@if`/`*ngIf` template slots for sidebar content**.
- `openSidebar(type, component)` — renders any component into the sidebar.

**Workflow state** — Angular signals (no NgRx), in `workflow.state.ts`:
`aragUrl`, `sidebar`, `selectedNode`, `preprocessNodes`, `contextNodes`, `generationNodes`, `postprocessNodes`, `childNodes`, `workflow`, `testAgent`

## Guards Summary

| Guard                    | Purpose                                                                              |
| ------------------------ | ------------------------------------------------------------------------------------ |

## SCSS

```scss
// Components use:
@use 'apps/dashboard/src/variables' as *;
// Exposes: colors, rhythm(), font-size(), title-*() mixins, font weights
```

ARAG tokens in `libs/common/src/lib/retrieval-agent/agent-dashboard/_agent-dashboard.tokens.scss`:
`$height-toolbar`, `$height-main`, `$width-sidebar`, `$width-sidebar-large`, `$padding-sidebar`

---

## Running Locally

```sh
nx serve dashboard           # against Nuclia stage (default)
nx serve dashboard -c local-prod  # against production
nx build dashboard
nx test dashboard
```

Config: `src/environments_config/{local-stage,local-prod,production}/app-config.json`

## Important Conventions

1. **Signal-based workflow state** — mutations via exported state functions in `workflow.state.ts` (`addNode()`, `deleteNode()`, `updateNode()`). Never mutate signals from outside the state file.
2. **Dynamic sidebar** — `WorkflowService.openSidebar()` uses `createComponent()`. No template slots.
3. **Shared ARAG code** — `AgentDashboardComponent` + all workflow code in `libs/common`. Dashboard-specific code: `app/` directory only.
4. **Module-based** — app uses NgModules; imported lib components may be standalone.
5. **UI ↔ API models** — `*AgentToUi()` (API → UI) and `*UiToCreation()` (UI → API) in `workflow.models.ts`.
6. **Lazy modules** — `AccountModule`, `UploadModule`, `ResourcesModule`, `MetricsModule` (+ `ActivityModule` inside it), `WIDGETS_ROUTES`, `TASK_AUTOMATION_ROUTES`, `LazyUserModule` are all lazy-loaded.
7. **`/metrics` always loads `MetricsModule`** — the legacy REMI-only page and the `metricsDisabledGuard`/`metricsEnabledGuard` split were removed. `MetricsModule` is always loaded when the `/metrics` route is activated.
8. **Activity logs moved to `/metrics/detailed`** — `ActivityModule` (`libs/common/src/lib/metrics/activity/`) is lazy-loaded inside `MetricsModule` at the `detailed` child route. There is no longer a standalone `/activity` route on the KB.
9. **`/user/callbacks/saml` is temporary** — added for IDP-initiated SAML clients whose `RelayState` points here. Remove once those clients are updated to use the auth app's URL.
10. **`/simple` frictionless UI** — `SimplePageModule` is lazy-loaded; `SimplePageComponent` inspects the user role and routes to `ReaderExperienceComponent` (reader: search-only) or `SimpleKBComponent` (admin/contrib: upload + search). Gated by `FeaturesService.unstable.simpleUI`.
11. **ARAG routes now under `/workflows`** — `/:zone/arag/:agent` redirects to `./workflows`. `WorkflowsListComponent` shows all workflows; `AgentDashboardComponent` is at `./workflows/:id`.
12. **`/user/set-password`** — `SetPasswordComponent` is a dedicated route for setting a password after being invited or after signup. Distinct from `/user/reset` (which uses a magic token from an email link).
13. **KB routes guarded by `knowledgeBoxOwnerGuard`** — `/manage`, `/ai-models`, `/widgets`, `/users`, `/keys` under `/:zone/:kb` all require `knowledgeBoxOwnerGuard` (KB owner/admin). ARAG equivalents use `aragOwnerGuard`.
14. **`/prompt-lab` redirect** — permanently redirects to `/rag-lab`. Old bookmarks continue to work.
15. **ARAG `/sources` route** — previously named `/drivers`, renamed to `/sources`. `DriversPageComponent` (name unchanged) renders data sources.
