# Installation

> Install OpenInference JavaScript packages for tracing LLM applications

## Requirements

OpenInference JavaScript requires:

* Node.js 10 or higher
* npm, yarn, or pnpm package manager

## Installation

### Core Dependencies

First, install the OpenTelemetry SDK packages:

<CodeGroup>
  ```bash npm theme={null}
  npm install --save @opentelemetry/exporter-trace-otlp-http \
    @opentelemetry/exporter-trace-otlp-proto \
    @opentelemetry/resources \
    @opentelemetry/sdk-trace-node \
    @opentelemetry/instrumentation
  ```

  ```bash yarn theme={null}
  yarn add @opentelemetry/exporter-trace-otlp-http \
    @opentelemetry/exporter-trace-otlp-proto \
    @opentelemetry/resources \
    @opentelemetry/sdk-trace-node \
    @opentelemetry/instrumentation
  ```

  ```bash pnpm theme={null}
  pnpm add @opentelemetry/exporter-trace-otlp-http \
    @opentelemetry/exporter-trace-otlp-proto \
    @opentelemetry/resources \
    @opentelemetry/sdk-trace-node \
    @opentelemetry/instrumentation
  ```
</CodeGroup>

### Instrumentation Packages

Install the instrumentation for your LLM framework:

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

  # LangChain
  npm install --save @arizeai/openinference-instrumentation-langchain

  # Anthropic
  npm install --save @arizeai/openinference-instrumentation-anthropic

  # AWS Bedrock
  npm install --save @arizeai/openinference-instrumentation-bedrock
  ```

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

  # LangChain
  yarn add @arizeai/openinference-instrumentation-langchain

  # Anthropic
  yarn add @arizeai/openinference-instrumentation-anthropic

  # AWS Bedrock
  yarn add @arizeai/openinference-instrumentation-bedrock
  ```

  ```bash pnpm theme={null}
  # OpenAI
  pnpm add @arizeai/openinference-instrumentation-openai

  # LangChain
  pnpm add @arizeai/openinference-instrumentation-langchain

  # Anthropic
  pnpm add @arizeai/openinference-instrumentation-anthropic

  # AWS Bedrock
  pnpm add @arizeai/openinference-instrumentation-bedrock
  ```
</CodeGroup>

### Manual Instrumentation

For manual instrumentation, install the semantic conventions package:

<CodeGroup>
  ```bash npm theme={null}
  npm install --save @arizeai/openinference-semantic-conventions
  ```

  ```bash yarn theme={null}
  yarn add @arizeai/openinference-semantic-conventions
  ```

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

### Core Utilities (Optional)

For advanced tracing features like context propagation and span wrappers:

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

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

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

## Basic Setup

Create an instrumentation file to configure OpenTelemetry:

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

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

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

<Warning>
  The instrumentation must run **before** any other code in your application. Load it using the `-r` flag:

  ```bash theme={null}
  node -r ./instrumentation.js ./app.js
  ```
</Warning>
