# Phase 9 — Content Modernization, Publication Features & SEO Enrichment

## Status: Implemented; Linux validation pending

Implemented in this pass:

- Additive Prisma models/fields for SEO metadata, article view logs, newsletter campaigns, article series, editorial reviews, comment likes, and reading lists.
- Backend APIs for related articles, public series pages, newsletter unsubscribe, admin analytics, review workflow, newsletter campaigns, series management, comment likes, and authenticated reading lists.
- Frontend API clients and visible admin panels for analytics, reviews, newsletter campaigns, and series management.
- Article page support for comment likes, API-backed related articles, author/profile navigation, and richer SEO metadata consumption.
- Seed/reference content now finalizes 23 published articles, refreshes old dates/slugs, promotes former draft/review items, and adds Phase 9 SEO fields.
- Sitemap/RSS generation now uses canonical paths, `dateModified`, `metaDescription`, and full-content RSS payloads.

Not run locally by request: frontend/backend builds and Prisma generation. Validate on Linux with the commands in `ARCH.md`/`AGENTS.md`.

All work targets the `SERVER/` directory. Content research uses web search and Context7 for technical accuracy. Schema changes are additive (nullable/defaulted) and backward-compatible.

---

## Overview

Phase 9 has three pillars:

1. **Content modernization.** 17 of 18 articles have placeholder content. All are dated 1403. AI model references are two generations stale. The publication needs to be current, factually accurate, and complete.
2. **Publication features.** Ten features a real tech publication needs but Teknav currently lacks: newsletter campaigns, article series, related articles, comment votes, writer analytics, syntax highlighting, social share, admin time-series charts, editorial review workflow, and a bookmark/reading-list system.
3. **SEO enrichment.** Every article needs `metaDescription`, Open Graph metadata, JSON-LD structured data, and a canonical URL. OG images generated locally. Sitemap and RSS updated.

## 9.3 — SEO Metadata Layer

### New Fields per Article in `teknav-data.js`

```js
{
  metaDescription: '...',      // 120–155 chars, Persian plain text
  keywords: ['کلمه ۱', ...],   // 6–10 Persian terms
  ogTitle: '...',              // og:title override (defaults to title)
  ogDescription: '...',        // 200–300 chars for og:description
  ogImage: '/images/og/slug.jpg',
  canonicalPath: '/articles/slug',
  dateModified: '2026-...',    // ISO — for JSON-LD dateModified and sitemap <lastmod>
}
```

### Prisma Schema Changes

```prisma
model Article {
  // existing fields unchanged ...
  metaDescription  String?   @db.VarChar(160)
  keywords         String[]  @default([])
  ogTitle          String?   @db.VarChar(200)
  ogDescription    String?   @db.VarChar(300)
  ogImage          String?
  canonicalPath    String?
  dateModified     DateTime?
}
```

All nullable/defaulted — no migration failure on existing rows. After change: `prisma:generate` → `prisma:apply`.

### `seed.ts` Update

Extend the article upsert to include all new SEO fields.

### Article Detail Page `<head>` Block

```html
<title>{title} | تکناو</title>
<meta name="description" content="{metaDescription}" />
<meta name="keywords" content="{keywords.join(',')}" />
<link rel="canonical" href="https://www.teknav.ir{canonicalPath}" />

<meta property="og:type" content="article" />
<meta property="og:title" content="{ogTitle || title}" />
<meta property="og:description" content="{ogDescription || metaDescription}" />
<meta property="og:image" content="https://www.teknav.ir{ogImage}" />
<meta property="og:url" content="https://www.teknav.ir{canonicalPath}" />
<meta property="og:locale" content="fa_IR" />
<meta property="og:site_name" content="تکناو" />
<meta property="article:published_time" content="{dateEn}" />
<meta property="article:modified_time" content="{dateModified}" />
<meta property="article:author" content="{authorName}" />
<meta property="article:section" content="{categoryName}" />

<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="{ogTitle || title}" />
<meta name="twitter:description" content="{metaDescription}" />
<meta name="twitter:image" content="https://www.teknav.ir{ogImage}" />
```

### JSON-LD Structured Data

Inject `<script type="application/ld+json">` in article detail page:

```json
{
  "@context": "https://schema.org",
  "@type": "Article",
  "headline": "{title}",
  "description": "{metaDescription}",
  "datePublished": "{dateEn}",
  "dateModified": "{dateModified}",
  "inLanguage": "fa",
  "author": {
    "@type": "Person",
    "name": "{authorName}",
    "url": "https://www.teknav.ir/profile/@{authorUsername}"
  },
  "publisher": {
    "@type": "Organization",
    "name": "تکناو",
    "url": "https://www.teknav.ir",
    "logo": { "@type": "ImageObject", "url": "https://www.teknav.ir/favicon.png" }
  },
  "image": "https://www.teknav.ir{ogImage}",
  "mainEntityOfPage": { "@type": "WebPage", "@id": "https://www.teknav.ir{canonicalPath}" }
}
```

---

## 9.4 — OG Image Generation

Node script `scripts/generate-og-images.mjs` uses `@napi-rs/canvas` (npm, zero CDN) to produce 23 × 1200×630 JPEG files in `public/images/og/`. Each image: category brand color background, site name top-right, article title centered (Vazirmatn font loaded locally), category badge bottom-right.

---

## 9.5 — SEO Artifacts Refresh

- Update `scripts/generate-seo.mjs` to use `dateModified` in sitemap `<lastmod>` and `metaDescription` in RSS `<description>`.
- RSS `<content:encoded>` must include the full article HTML.
- Run `npm run seo:sitemap` after all content changes.

---

## 9.6 — Article Status Cleanup

art17 (`rust-systems`) is `پیش‌نویس` and art18 (`venture-capital-ai`) is `در انتظار بررسی`. Both get full content in Phase 9 and are promoted to `منتشرشده`.

---

## 9.7 — Newsletter Campaign System

### Goal
The platform already collects subscriber emails. Phase 9 closes the loop: admins compose and send a newsletter campaign to all confirmed subscribers directly from the admin panel.

### Schema

```prisma
model NewsletterCampaign {
  id          String    @id @default(cuid())
  subject     String    @db.VarChar(200)
  bodyHtml    String    @db.Text
  sentAt      DateTime?
  recipientCount Int    @default(0)
  createdBy   User      @relation(fields: [createdById], references: [id])
  createdById Int
  createdAt   DateTime  @default(now())
}
```

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `GET` | `/api/v1/admin/newsletter/campaigns` | admin | List all campaigns |
| `POST` | `/api/v1/admin/newsletter/campaigns` | admin | Create draft campaign |
| `POST` | `/api/v1/admin/newsletter/campaigns/:id/send` | admin | Send to all active subscribers |
| `GET` | `/api/v1/admin/newsletter/subscribers` | admin | List subscribers |

### Send Logic
- `POST .../send` is idempotent — once `sentAt` is set, re-sending returns 409.
- Uses existing `backend/src/lib/email.ts` SMTP sender.
- Sends in batches of 50 with a 200ms delay between batches to avoid SMTP rate limits.
- Each email includes a plain-text unsubscribe link: `https://www.teknav.ir/api/v1/newsletter/unsubscribe?token={token}`.
- Each `NewsletterSubscriber` row gets a unique `unsubscribeToken` (random UUID, generated on subscription).
- `GET /api/v1/newsletter/unsubscribe?token=` removes the subscriber and returns a plain 200.

### Schema Addition to NewsletterSubscriber

```prisma
model NewsletterSubscriber {
  // existing fields ...
  unsubscribeToken String @unique @default(cuid())
}
```

### Frontend (Admin)
- New "خبرنامه" tab in admin sidebar (admin role only).
- Campaign list with status (پیش‌نویس / ارسال‌شده), subject, recipient count, send date.
- Campaign composer: subject input + HTML textarea (same editor controls as article editor).
- Preview renders the HTML in a sandboxed `<iframe>`.
- "ارسال به همه مشترکان" button with a count confirmation dialog: "ارسال به ۱٬۲۳۴ مشترک؟".
- Subscriber list panel: table of emails + subscribe date + unsubscribe button.

---

## 9.8 — Article Series

### Goal
Group thematically linked articles into ordered series (e.g., «سری: راهنمای کامل LLMها»). Readers see their position in the series and can navigate between parts. Great for long-form coverage and reader retention.

### Schema

```prisma
model ArticleSeries {
  id          String          @id @default(cuid())
  title       String          @db.VarChar(200)
  slug        String          @unique
  description String?         @db.VarChar(500)
  coverImage  String?
  createdAt   DateTime        @default(now())
  articles    SeriesArticle[]
}

model SeriesArticle {
  id        String        @id @default(cuid())
  series    ArticleSeries @relation(fields: [seriesId], references: [id], onDelete: Cascade)
  seriesId  String
  article   Article       @relation(fields: [articleId], references: [id], onDelete: Cascade)
  articleId String
  position  Int

  @@unique([seriesId, articleId])
  @@unique([seriesId, position])
}
```

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `GET` | `/api/v1/series` | public | List all series |
| `GET` | `/api/v1/series/:slug` | public | Series detail with ordered articles |
| `GET` | `/api/v1/admin/series` | editor+ | Admin list |
| `POST` | `/api/v1/admin/series` | editor+ | Create series |
| `PATCH` | `/api/v1/admin/series/:id` | editor+ | Update title/description/cover and ordered article list |
| `DELETE` | `/api/v1/admin/series/:id` | editor+ | Delete series |

### Frontend
- **Series page** `/series/:slug` — cover, description, ordered article list with part numbers (قسمت ۱، قسمت ۲...).
- **Article detail** — if the article belongs to a series, show a "این مقاله بخشی از سری..." banner above the content. Banner includes prev/next navigation.
- **Admin series management** — new "سری‌ها" tab in admin sidebar. Create/edit series, drag-and-drop to reorder articles using a simple up/down button pair (no drag library needed).

---

## 9.9 — Related Articles Engine

### Goal
Show three related articles at the bottom of every article. Relation is computed by tag overlap — no ML needed. Results cached in Redis.

### Backend

New route: `GET /api/v1/articles/:slug/related` — returns up to 3 articles.

Algorithm:
1. Get the current article's tag IDs.
2. Find published articles sharing the most tags (excluding self), limited to 3.
3. Tiebreak by `views DESC`.
4. Cache result in Redis `related:{articleId}` with TTL 1 hour.
5. Clear cache when any article is published, edited, or deleted.

```sql
-- Prisma raw for tag overlap score
SELECT a.id, COUNT(at.tagId) AS overlap
FROM Article a
JOIN ArticleTag at ON at.articleId = a.id
WHERE at.tagId IN (<current article tag IDs>)
  AND a.id != <current article id>
  AND a.status = 'منتشرشده'
GROUP BY a.id
ORDER BY overlap DESC, a.views DESC
LIMIT 3
```

### Frontend
- `RelatedArticles` component at the bottom of `ArticleDetail`, after comments.
- Three cards in a horizontal row (single column on mobile), each showing cover color, title, category, read time, author.
- Loaded via `GET /api/v1/articles/:slug/related` on article mount.

---

## 9.10 — Comment Helpfulness Votes

### Goal
Readers can upvote useful comments. Comments with more votes sort higher. Discourages noise and surfaces quality discussion.

### Schema

```prisma
model CommentLike {
  id        String   @id @default(cuid())
  comment   Comment  @relation(fields: [commentId], references: [id], onDelete: Cascade)
  commentId String
  user      User     @relation(fields: [userId], references: [id])
  userId    Int
  createdAt DateTime @default(now())

  @@unique([commentId, userId])
}
```

Add `likeCount Int @default(0)` to the `Comment` model.

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `POST` | `/api/v1/comments/:id/like` | session | Toggle like (like if not liked, unlike if already liked) |

`GET /api/v1/articles/:slug/comments` — add `likeCount` and `likedByMe` (bool, based on session) to each comment object. Default sort changes to: top-level comments ordered by `likeCount DESC, createdAt DESC`.

### Frontend
- Each comment card shows a "👍 مفید بود ({likeCount})" button (no emoji in production — use an SVG thumbs-up from global SVG sprite or inline).
- Authenticated users can click to toggle. The count updates optimistically.
- The button is teal-accented when liked by the current user, muted otherwise.
- Guests see the count but cannot vote.

---

## 9.11 — Writer Analytics Dashboard

### Goal
Writers see per-article performance stats: views over time, reaction breakdown, comment counts, and follower growth. Editors and admins see the same for any article. Data visualised with pure SVG sparklines — no chart library dependency.

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `GET` | `/api/v1/auth/analytics/overview` | session (writer+) | Total views, reactions, comments, followers |
| `GET` | `/api/v1/auth/analytics/articles` | session (writer+) | Per-article stats list |
| `GET` | `/api/v1/auth/analytics/article/:slug` | session (writer+, must own or be editor+) | Daily view/reaction time-series for one article (last 30 days) |

### Time-Series Data Source
The existing `ActivityLog` table logs article publishes. Views are buffered in Redis and flushed to the `Article.views` field. For a time-series breakdown, add:

```prisma
model ArticleViewLog {
  id        String   @id @default(cuid())
  article   Article  @relation(fields: [articleId], references: [id], onDelete: Cascade)
  articleId String
  date      DateTime @db.Date
  views     Int      @default(0)

  @@unique([articleId, date])
}
```

`flushViewCounters()` (which already runs every 60s) is extended to also upsert a `ArticleViewLog` row for today's date. This gives per-day granularity.

### Frontend
- New "آمار" tab in the writer's profile settings panel (visible to own writer/editor/admin).
- Overview cards: کل بازدیدها، کل واکنش‌ها، کل نظرها، دنبال‌کنندگان.
- Article table: slug, title, views, reactions, comments — sortable.
- Clicking an article row shows a 30-day sparkline (SVG, pure path element) for views.
- SVG sparkline: 300×60px, line chart, no axes — just the trend shape.

---

## 9.12 — Local Syntax Highlighting

### Goal
Technical articles with `<pre><code>` blocks render highlighted code. Highlight.js installed via npm (not CDN). Auto-detects language from `class="language-*"`. RTL article layout must not break LTR code blocks.

### Implementation

Install: `npm install highlight.js` in root package.json.

In `teknav-articles.jsx`, after the article HTML is injected via `dangerouslySetInnerHTML`, use a `useEffect` to:
1. Query all `pre code` elements inside the article body.
2. Call `hljs.highlightElement(el)` on each.
3. Force `direction: ltr; text-align: left` on every `<pre>` via inline style so RTL layout doesn't reverse code.

Import only the languages needed to keep bundle size small:
- `javascript`, `typescript`, `python`, `bash`, `sql`, `json`, `rust`, `go`, `yaml`, `docker`

Register them with `hljs.registerLanguage(...)`. Do not use `hljs.highlightAll()` (too broad).

Add a highlight.js theme (`github-dark.min.css`) to `src/styles/` — copied from the npm package's `styles/` folder, never from a CDN.

Add a language label above each code block: read the `class` attribute, strip `language-`, show as a small badge (e.g., `python`).

### Zero CDN Check
`scripts/check-no-cdn.mjs` must not flag highlight.js. Since it's bundled via Vite from npm, it produces a local `/assets/...` chunk — no external URL. Verify after `npm run build`.

---

## 9.13 — Social Share (URL-Scheme Only)

### Goal
Readers can share articles to Telegram, Twitter/X, and WhatsApp, and copy the article URL to clipboard. Zero CDN — all share actions use URL schemes or the browser Clipboard API. No tracking pixels.

### Frontend

`SocialShare` component rendered in `ArticleDetail` below the article byline.

Share targets:

| Platform | URL scheme |
|---|---|
| Telegram | `https://t.me/share/url?url={url}&text={title}` |
| Twitter/X | `https://x.com/intent/tweet?url={url}&text={title}` |
| WhatsApp | `https://api.whatsapp.com/send?text={title}+{url}` |
| Copy link | `navigator.clipboard.writeText(url)` → toast "لینک کپی شد" |

All share URLs open in a new tab (`target="_blank" rel="noopener"`). Icons are inline SVGs from a local sprite (no CDN icon fonts). Buttons are small and unobtrusive — placed in a compact row right of the article metadata line.

Share count is NOT tracked (avoids the need for a counter service or extra storage).

---

## 9.14 — Admin Time-Series Analytics

### Goal
Admin and editor roles see trend charts in the dashboard: daily active users (7-day), new registrations (30-day), total article views (30-day), and top 5 articles of the week. All charts are pure SVG — no chart.js or D3 dependency.

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `GET` | `/api/v1/admin/analytics` | writer+ | Views by day and top articles |
| `GET` | `/api/v1/admin/analytics/content` | writer+ | Content performance analytics |
| `GET` | `/api/v1/admin/analytics/newsletter` | editor+ | Newsletter analytics |
| `GET` | `/api/v1/admin/analytics/engagement` | writer+ | Engagement event analytics |

### Data Source

User registrations: aggregate `User.createdAt` by date.

Views: sum `ArticleViewLog.views` grouped by date (requires 9.11's `ArticleViewLog` model).

Top articles: sum `ArticleViewLog.views` where `date >= 7 days ago`, group by article, top 5.

### Frontend
- New "آمار سایت" panel in admin dashboard (below the live feed widget).
- Two SVG bar charts: "ثبت‌نام روزانه (۳۰ روز)" and "بازدید روزانه (۳۰ روز)".
- Bar chart: 300×120px SVG. Bars drawn as `<rect>` elements, scaled to max value. Day labels below each bar (Persian numerals, rotated 45°). Hover tooltip showing exact value.
- Top articles table: rank, title (linked), category, 7-day views.

### SVG Bar Chart Component
Pure React component, no dependencies:
```jsx
function BarChart({ data, label }) {
  const max = Math.max(...data.map(d => d.value), 1);
  const W = 300, H = 100, BAR_W = Math.floor(W / data.length) - 2;
  return (
    <svg width={W} height={H} style={{ direction: 'ltr' }}>
      {data.map((d, i) => {
        const h = Math.round((d.value / max) * (H - 20));
        return <rect key={i} x={i * (BAR_W + 2)} y={H - 20 - h} width={BAR_W} height={h} fill="#0F6B73" rx={2} />;
      })}
    </svg>
  );
}
```

---

## 9.15 — Editorial Submission & Review Workflow

### Goal
Writers submit articles for editorial review. Editors see a "صف بررسی" (review queue) panel. Editors can approve (publish), request revisions, or reject with a note. Writers get an in-app notification of the decision.

### Schema

```prisma
enum ReviewStatus {
  pending
  revision_requested
  approved
  rejected
}

model ArticleReview {
  id        String       @id @default(cuid())
  article   Article      @relation(fields: [articleId], references: [id], onDelete: Cascade)
  articleId String       @unique
  reviewer  User?        @relation(fields: [reviewerId], references: [id])
  reviewerId Int?
  status    ReviewStatus @default(pending)
  note      String?      @db.VarChar(1000)
  createdAt DateTime     @default(now())
  updatedAt DateTime     @updatedAt
}
```

The existing `Article.status` enum gains a new value: `در_انتظار_بررسی` (already exists in data but now is the formal submission state).

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `GET` | `/api/v1/admin/reviews` | writer+ | List review queue items visible to the current role |
| `PUT` | `/api/v1/admin/articles/:id/review` | reviewer/editor/admin | Approve, request revision, or reject with note |

### Notification Events
Reuse the Phase 8 `Notification` model with new types:

```prisma
enum NotificationType {
  comment
  comment_reply
  new_article
  review_approved    // new
  review_revision    // new
  review_rejected    // new
  review_submitted   // new — sent to editors when writer submits
}
```

### Frontend
- **Writer article editor** — "ارسال برای بررسی" button visible when article is in draft or revision_requested state.
- **Admin sidebar** — new "صف بررسی" tab with a badge showing pending count (editor+ only).
- **Review queue panel** — article title, author, category, word count, submit date. Action buttons: تأیید و انتشار / درخواست اصلاح / رد کردن. "درخواست اصلاح" and "رد کردن" open a note textarea before sending.
- **Writer notification** — bell notification with the editor's decision and note.
- **Article status badge** — `ArticleDetail` in admin view shows the current review status clearly.

---

## 9.16 — Saved Articles & Reading List Enhancement

### Goal
Phase 4 added a `save` API but the frontend reading list is minimal. Phase 9 elevates it: users can organize saved articles into named lists (e.g., "بعداً بخوانم"، "مقالات مرجع")، reorder items, and access the list from their profile.

### Schema

Each user gets a default list "ذخیره‌شده" created on first save. The existing `SavedArticle` model (Phase 4) is migrated to this system.

### Backend Routes

| Method | Path | Auth | Description |
|---|---|---|---|
| `GET` | `/api/v1/auth/lists` | session | Get user's reading lists |
| `POST` | `/api/v1/auth/lists` | session | Create a list |
| `DELETE` | `/api/v1/auth/lists/:id` | session | Delete a list (not default) |
| `POST` | `/api/v1/auth/lists/:id/items` | session | Add article to list |
| `DELETE` | `/api/v1/auth/lists/:id/items/:articleId` | session | Remove article |
| `PUT` | `/api/v1/auth/lists/:id/reorder` | session | Reorder items |

### Frontend
- Profile "ذخیره‌شده" tab shows reading lists, each expandable to see its articles.
- "+" button to create a new named list.
- Save button on articles now opens a small dropdown: pick which list to save to (or create new).
- Reading list items show article cover color, title, category, and a remove button.

## Dependencies to Add

| Package | Location | Purpose |
|---|---|---|
| `@napi-rs/canvas` | root (devDependency) | OG image generation script |
| `highlight.js` | root | Local syntax highlighting |

Both installed via npm. Neither violates the zero-CDN policy — they are bundled locally by Vite.

## Implementation Sequence

1. Web-search each article topic for 1405/2026 state.
2. Write full content for art2–art18 + update art1.
3. Write full content for art19–art23 (new articles).
4. Add SEO fields to all 23 articles in `teknav-data.js`, update dates.
5. Rename art10 slug.
6. Add SEO + `ArticleViewLog` + `NewsletterCampaign` + `ArticleSeries` + `SeriesArticle` + `CommentLike` + `ArticleReview` + `ReviewStatus` + `ReadingList` + `ReadingListItem` + extended `NotificationType` to `schema.prisma`.
7. Run `prisma:generate` → `prisma:apply`.
8. Update `seed.ts` to upsert SEO fields and create default reading lists for seeded users.
9. Implement backend routes: newsletter campaigns (9.7), series (9.8), related articles (9.9), comment likes (9.10), writer analytics + `ArticleViewLog` flush (9.11), admin analytics (9.14), editorial review (9.15), reading lists (9.16).

15. Update `scripts/generate-seo.mjs` for `dateModified` and RSS `<content:encoded>`.
16. Run `npm run seo:sitemap`.
17. Run `npm run build` — verify zero CDN, check highlight.js bundle chunk is local.
18. Run `cd backend && npm run build`.

## Phase 9 Checklist

Current implementation status: core schema, seed/reference data, SEO artifacts, public APIs, admin APIs, and primary frontend entry points are implemented. Several originally listed polish items remain intentionally pending for Linux/browser validation or a later UI pass: full researched 800-word rewrites for every legacy article, syntax-highlighting runtime integration, dedicated writer analytics profile tab, richer social-share buttons, article-series prev/next navigation, review notifications, and reading-list picker UI.
