dotenv

Read configuration values from a .env file or the surrounding process environment.

Import:

import "dotenv";

envvar

Look up a value by name. If a .env file is present in the working directory, its keys are loaded automatically.

string key = envvar("AI_API_KEY");
string url = envvar("AI_URL");

Example .env

AI_URL=https://api.openai.com/v1/chat/completions
AI_MODEL=gpt-4
AI_API_KEY=sk-...
