Environment Variables

To call your LLM from a third-party service, you’ll likely need some environment variables to keep your API keys safe.

Since Evalite is based on Vitest, it should already pick them up from your vite.config.ts.

Setting Up Env Variables

If you don’t have Vitest set up, here’s how to do it:

Create a .env file in the root of your project:
.env
```
OPENAI_API_KEY=your-api-key
```
Add .env to your .gitignore, if it’s not already there
.gitignore
```
.env
```
Install dotenv:
Terminal window
```
pnpm add -D dotenv
```

Add a vite.config.ts file:

import { defineConfig } from "vite";

export default defineConfig({
  test: {
    setupFiles: ["dotenv/config"],
  },
});

Now, your environment variables will be available in your evals.
