Search\nthrough your documents using natural language queries.\n\n## Quickstart\n\n```typescript\nimport PineconeIndex from \"https://esm.town/v/peterqliu/PineconeIndex/PineconeIndex\";\n\n// set up your environment variables\nconst pineconeKey = Deno.env.get(\"PINECONE_KEY\");\nconst modelToken = Deno.env.get(\"OPENAI_KEY\");\n\nconst index = new PineconeIndex({\n name: \"2025-all-docs\",\n model: \"text-embedding-ada-002\",\n dimensions: 1536,\n pineconeKey,\n modelToken,\n});\n\nawait index.create();\n\n// Using the methods directly (see bottom of README for HTTP access)\nconst results = await index.query(\"machine learning applications\");\nawait index.upsertRecords([\"Document 1\", \"Document 2\"]);\nawait index.empty();\n```\n\n## API Reference\n\n### Search Documents\n\nFind the most relevant documents for your query.\n\n```typescript\nconst results = await index.query(\"your search text\");\n```\n\n**Returns:**\n\n```json\n{\n \"matches\": [\n {\n \"id\": \"doc-123\",\n \"score\": 0.95,\n \"metadata\": {\n \"text\": \"Machine learning is transforming...\"\n }\n }\n ]\n}\n```\n\n### Add Documents\n\nUpload new documents to your index.\n\n```typescript\nawait index.upsertRecords([\n \"First document content\",\n \"Second document content\",\n]);\n```\n\n### Clear Index\n\nRemove all documents from your index.\n\n```typescript\nawait index.empty();\n```\n\n### Create Index\n\nCreate a new Pinecone index (if it doesn't exist).\n\n```typescript\nawait index.create();\n```\n\n## Usage Examples\n\n### Basic Usage\n\n```typescript\nimport PineconeIndex from \"https://esm.town/v/peterqliu/PineconeIndex/PineconeIndex\";\n\nconst index = new PineconeIndex({\n name: \"my-documents\",\n model: \"text-embedding-ada-002\",\n dimensions: 1536,\n pineconeKey: Deno.env.get(\"PINECONE_KEY\"),\n modelToken: Deno.env.get(\"OPENAI_KEY\"),\n});\n\n// Add some documents\nawait index.upsertRecords([\n \"AI is revolutionizing healthcare\",\n \"Machine learning enables automation\",\n \"Solar energy is becoming more efficient\",\n]);\n\n// Search for relevant documents\nconst results = await index.query(\"renewable energy technologies\");\nconsole.log(results.matches);\n```\n\n## Remote HTTP access\n\nPineconeIndex also provides `handleRequest` as a convenience method to access\nyour indices via HTTP. This is useful when multiple other vals need to access,\nor for granting access without sharing Pinecone or OpenAI keys.\n\n### Server setup\n\n```typescript\nconst index = new PinconeIndex({...});\n\nexport default async function (req: Request): Promise {\n return await index.handleRequest(req);\n}\n```\n\n### Usage\n\nOperations are determined by the URL path. The first segment after the domain\nspecifies the operation to perform.\n\n```javascript\nconst API_URL = \"https://your-server-url.web.val.run\";\n\n// Search for documents: append the desired operation to the url\nconst searchResponse = await fetch(`${API_URL}/query/`, {\n method: \"POST\",\n headers: { \"Content-Type\": \"application/json\" },\n body: JSON.stringify(\"artificial intelligence trends\"),\n});\n```",[134],"2fb1b12e-ddfb-11f0-969c-42dde27851f2","550e6a1c-6d75-11f0-9956-0224a6c84d84",115,["D",1766273135505],88,"script","import { Pinecone } from \"npm:@pinecone-database/pinecone\";\nimport axios from \"npm:axios\";\nimport { v4 as uuidv4 } from \"npm:uuid\"; // for generating unique IDs\n\n\nexport default class PineconeIndex {\n \n constructor(options) {\n const {name, dimensions, pineconeIndex, pineconeKey, modelToken, model} = options;\n\n this.options = options;\n this.pc = new Pinecone({ apiKey: pineconeKey });\n this._index = null;\n this._namespace = options.namespace ?? \"\";\n }\n \n async create() {\n const { name, dimension } = this.options;\n await this.pc.createIndex({\n name,\n dimension,\n metric: 'cosine',\n spec: { serverless: { cloud: 'aws', region: 'us-east-1' } },\n deletionProtection: 'disabled',\n waitUntilReady: true\n });\n\n // Immediately capture index host\n const {host} = await this.pc.describeIndex(name);\n this._index = this.pc.Index(host);\n }\n\n async getIndex() {\n if (this._index) return this._index;\n \n const { name } = this.options;\n const {host} = await this.pc.describeIndex(name);\n const idx = this.pc.index(name, host);\n \n const ns = this._namespace;\n this._index = ns ? idx.namespace(ns) : idx;\n return this._index;\n }\n\n \n async upsertRecords(texts) {\n const idx = await this.getIndex();\n \n // Process texts one at a time to avoid message size limits\n for (const text of texts) {\n const values = await this.embed(text);\n const vector = {\n id: uuidv4(), // generate unique ID per text\n values,\n metadata: { text }, // keep original text in metadata\n };\n \n await idx.upsert([vector]);\n }\n }\n\n async query(text:string){\n const idx = await this.getIndex();\n const vector = await this.embed(text);\n return idx.query({\n vector,\n topK: 10,\n includeValues: false,\n includeMetadata: true,\n });\n }\n\n async embed(text:string) {\n const {model, modelToken} = this.options;\n const response = await axios.post(\n \"https://api.openai.com/v1/embeddings\",\n {model, input: text }, \n {\n headers: {\n \"Authorization\": `Bearer ${modelToken}`,\n },\n }\n );\n \n return response.data.data[0].embedding;\n }\n\n async empty() {\n const idx = await this.getIndex();\n \n // Delete all vectors in the current namespace\n // If no namespace is set, this will delete all vectors in the index\n await idx.deleteAll();\n }\n\n /**\n * HTTP handler that routes requests to appropriate methods\n * Supports routes like /query/, /upsert/, /empty/\n */\n async handleRequest(req: Request): Promise {\n const url = new URL(req.url);\n const pathSegments = url.pathname.split('/').filter(segment => segment.length > 0);\n \n // Extract the operation from the path (e.g., \"query\" from \"/query/\")\n const operation = pathSegments[0];\n \n try {\n switch (operation) {\n case 'query':\n return await this._handleOperation(req, 'POST', async (body) => {\n // Support both direct string and object with query property\n const queryText = typeof body === 'string' ? body : (body.query || body.text || JSON.stringify(body));\n \n if (!queryText) {\n throw new Error('Query text is required');\n }\n\n const results = await this.query(queryText);\n return results;\n });\n \n case 'upsert':\n return await this._handleOperation(req, 'POST', async (body) => {\n const texts = body.texts || body.data || (Array.isArray(body) ? body : [body]);\n \n if (!Array.isArray(texts) || texts.length === 0) {\n throw new Error('Texts array is required');\n }\n\n await this.upsertRecords(texts);\n return { success: true, count: texts.length };\n });\n \n case 'empty':\n return await this._handleOperation(req, 'POST', async () => {\n await this.empty();\n return { success: true, message: 'Index cleared' };\n });\n \n case 'health':\n return Response.json({ status: 'healthy', timestamp: new Date().toISOString() });\n \n default:\n return Response.json(\n { error: `Unknown operation: ${operation}.
