nuxt-pinecone

Nuxt module for Pinecone vector database. Provides a server-side usePinecone() composable with auto-import support.

Features

• 🔒  Server-only — API key is never exposed to the client
• ⚡  Auto-imported usePinecone() utility in server routes
• 🛠  Full PineconeConfiguration support (apiKey, controllerHostUrl, sourceTag, maxRetries, assistantRegion, caller)
• 📦  Zero config with environment variables

Quick Setup

Install the module to your Nuxt application:

npx nuxt module add nuxt-pinecone

Add it to your nuxt.config.ts:

export default defineNuxtConfig({
  modules: ['nuxt-pinecone'],
  pinecone: {
    // All PineconeConfiguration options are supported
    // apiKey is read from NUXT_PINECONE_API_KEY env var by default
  },
})

Set your API key via environment variable (recommended):

NUXT_PINECONE_API_KEY=your_api_key

Or directly in config (not recommended for production):

export default defineNuxtConfig({
  modules: ['nuxt-pinecone'],
  pinecone: {
    apiKey: 'your_api_key',
  },
})

Usage

Use the auto-imported usePinecone() composable in any server route or API handler:

// server/api/search.post.ts
export default defineEventHandler(async (event) => {
  const { query, topK } = await readBody(event)
  const pinecone = usePinecone()
  const index = pinecone.index('my-index')

  const results = await index.query({
    vector: query,
    topK: topK || 10,
    includeMetadata: true,
  })

  return results.matches
})

// server/api/indexes.get.ts
export default defineEventHandler(async () => {
  const pinecone = usePinecone()
  return await pinecone.listIndexes()
})

Configuration

All options from PineconeConfiguration are supported (except fetchApi and additionalHeaders which are not serializable):

| Option | Env Variable | Description | |--------|-------------|-------------| | apiKey | NUXT_PINECONE_API_KEY | Your Pinecone API key | | controllerHostUrl | NUXT_PINECONE_CONTROLLER_HOST_URL | Custom controller host URL | | sourceTag | NUXT_PINECONE_SOURCE_TAG | Tag applied to User-Agent header | | maxRetries | NUXT_PINECONE_MAX_RETRIES | Max retries after initial request (default: 3) | | assistantRegion | NUXT_PINECONE_ASSISTANT_REGION | Region for assistant APIs (default: "us") | | caller | — | Caller info for User-Agent (set in config) |
