# All JavaScript Packages

> Complete list of OpenInference JavaScript instrumentation packages

OpenInference provides a comprehensive set of JavaScript/TypeScript packages for instrumenting AI/ML applications with OpenTelemetry.

## Instrumentation Packages

These packages provide automatic instrumentation for popular AI SDKs and frameworks:

## Core Packages

These packages provide foundational functionality for building instrumentations and working with OpenInference:

| Package                                         | Description                                                                              | npm                                                                              |

## Installation

All packages are available via npm and can be installed using your preferred package manager:

<CodeGroup>
  ```bash npm theme={null}
  npm install @arizeai/openinference-instrumentation-openai
  ```

  ```bash yarn theme={null}
  yarn add @arizeai/openinference-instrumentation-openai
  ```

  ```bash pnpm theme={null}
  pnpm add @arizeai/openinference-instrumentation-openai
  ```
</CodeGroup>

## Common Features

All OpenInference JavaScript instrumentations provide:

* **Automatic Tracing**: Capture traces without modifying application code
* **OpenTelemetry Compatible**: Works with standard OpenTelemetry infrastructure
* **Context Propagation**: Automatically propagate session ID, user ID, metadata, and tags
* **Data Masking**: Support for hiding sensitive inputs/outputs via trace configuration
* **Custom Tracer Providers**: Ability to use non-global tracer providers
* **TypeScript Support**: Full TypeScript type definitions included

## Getting Started

Most instrumentations follow a similar pattern:

1. Install the instrumentation package
2. Create a tracer provider
3. Register the instrumentation
4. Use your AI SDK normally

Example:

```typescript theme={null}
import { NodeTracerProvider } from "@opentelemetry/sdk-trace-node";
import { OpenAIInstrumentation } from "@arizeai/openinference-instrumentation-openai";
import { registerInstrumentations } from "@opentelemetry/instrumentation";

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [new OpenAIInstrumentation()],
});

// Now use OpenAI SDK as normal - traces will be captured automatically
```
