+# config-node-package (Node Package)
+
+You can run this example with:
+
+```bash
+npx promptfoo@latest init --example config-node-package
+cd config-node-package
+```
+
+This example demonstrates using promptfoo from a Node.js script.
+
+## Prerequisites
+
+- Node.js ^20.20.0 or >=22.22.0 (Node.js 20 support ends July 30, 2026; Node.js 24 LTS recommended)
+- API keys for LLM providers set as environment variables:
+  - `OPENAI_API_KEY` - Get from [OpenAI API keys page](https://platform.openai.com/api-keys)
+  - `ANTHROPIC_API_KEY` - Get from [Anthropic Console](https://console.anthropic.com/) (optional)
+
+You can set these in a `.env` file:
+
+```text
+OPENAI_API_KEY=sk-your-key-here
+ANTHROPIC_API_KEY=sk-ant-your-key-here
+```
+
+## Running the Example
+
+1. Install dependencies:
+
+```bash
+npm install
+```
+
+2. Execute the script:
+
+```bash
+node full-eval.js
+```
+
+## Expected Results
+
+The script will:
+
+- Run evaluations programmatically using the promptfoo Node.js API
+- Save results to `output.json`
+- Display evaluation metrics in the console
+- Allow you to view detailed results with `promptfoo view`
