@vibecodeapp/proxy

A transparent fetch proxy that auto-patches global fetch on import. Zero configuration required—just import and go.

Installation

``bash
bun add @vibecodeapp/proxy
`

Quick Start

`typescript
import '@vibecodeapp/proxy'

// That's it! All fetch requests to supported AI APIs are now proxied.
const response = await fetch('https://api.openai.com/v1/chat/completions', {
method: 'POST',
headers: { 'Authorization': 'Bearer sk-...' },
body: JSON.stringify({ model: 'gpt-4', messages: [...] })
})
`

Configuration

$3

Set your project ID via environment variable:

`bash
VIBECODE_PROJECT_ID=your-project-id
`

$3

`typescript
import { setProxyProjectId, setProxiedDomains } from '@vibecodeapp/proxy'

// Set project ID at runtime
setProxyProjectId('your-project-id')

// Override the list of proxied domains
setProxiedDomains([
'api.openai.com',
'api.anthropic.com',
'custom-api.example.com'
])
`

Proxied Domains

By default, requests to these domains are routed through the proxy:

- api.openai.com
- api.anthropic.com
- api.x.ai
- amazonaws.com (includes Bedrock)
- generativelanguage.googleapis.com
- api.elevenlabs.io

The proxy also fetches an updated domain list from the server on initialization.

How It Works

1. Import-time patching: When you import the package, it immediately patches globalThis.fetch
2. URL matching: Each fetch request is checked against the list of proxied domains
3. Transparent routing: Matching requests are rewritten to go through proxy.vibecodeapp.com
4. Credential injection: Your project ID is added to proxied requests for authentication

`
Original: https://api.openai.com/v1/chat/completions
Proxied: https://api.openai.com.proxy.vibecodeapp.com/v1/chat/completions
`

API Reference

$3

Get the original, unpatched fetch function if you need to bypass the proxy.

`typescript
import { getOriginalFetch } from '@vibecodeapp/proxy'

const originalFetch = getOriginalFetch()
await originalFetch('https://api.openai.com/...') // Bypasses proxy
`
