Response containing news articles (headlines, sources, timestamps).\n\n### 3. **Code Node: Data Formatting**\n- **Purpose**: Transforms String Data into a loop-compatible array.\n- **Example Code**:\n ```javascript\n // Get the string with the news array\n let raw = $json[\"message\"];\n // Remove backticks and the \u2018json\u2019 tag if they exist\n raw = raw.replace(/```json|```/g, '').trim();\n // Parse the clean string into an array of objects\n const noticias = JSON.parse(raw);\n // Returns each news item as an individual item for the Loop\n return noticias.map(noticia => ({ json: noticia }));\n\n## 4. Loop Node: MongoDB Insertion\n**Action**: Iterates over each news item and inserts into MongoDB.\n\n**Configuration**:\n- **Collection**: `daily_news`\n- **Operation**: `Insert` \n- **Fields**: \n ```json\n {\n \"headline\": \"\",\n \"timestamp\": \"\",\n \"source\": \"\",\n \"url\": \"\",\n \"category\": \"\",\n \"metadata\": {}\n }\n\n## 5. Code Node: Aggregation & Notification Prep\n\n- **Purpose**: Wait for the news to be posted and then send a single notification email.\n\n## 6. Email Node (Gmail)\n\n- **Purpose**: Notification email\n\nWorkFlow\n A[Cron Trigger] --> B[Perplexity API]\n B --> C[Format Data]\n C --> D[Loop: MongoDB Insert]\n D --> E[Aggregate Results]\n E --> F[Send Email Notification]" }, "typeVersion": 1 }, { "id": "5f8fde92-09a5-44a2-9e8e-efebfcb84fd9", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ -160, -256 ], "parameters": { "color": 7, "width": 1504, "height": 672, "content": "" }, "typeVersion": 1 } ], "active": false, "settings": { "executionOrder": "v1" }, "versionId": "a765923b-a9ab-4567-a08f-132d54451d50", "connections": { "News": { "main": [ [ { "node": "Send Message", "type": "main", "index": 0 } ] ] }, "DB News": { "main": [ [ { "node": "Loop Over News", "type": "main", "index": 0 } ] ] }, "Perplexity": { "main": [ [ { "node": "Response Perplexity", "type": "main", "index": 0 } ] ] }, "Send Message": { "main": [ [] ] }, "Loop Over News": { "main": [ [ { "node": "News", "type": "main", "index": 0 } ], [ { "node": "DB News", "type": "main", "index": 0 } ] ] }, "Schedule Trigger": { "main": [ [ { "node": "Perplexity", "type": "main", "index": 0 } ] ] }, "Response Perplexity": { "main": [ [ { "node": "Loop Over News", "type": "main", "index": 0 } ] ] } } }
