Overview
direnv automatically loads/unloads environment variables when you cd into a directory. No more source .env — enter the project folder and variables are set.
Instructions
Step 1: Install
brew install direnv
# Add to .bashrc or .zshrc:
eval "$(direnv hook bash)"
Step 2: Configure
# .envrc — Auto-loaded when entering directory
export DATABASE_URL="postgresql://localhost:5432/myapp"
export API_KEY="sk-dev-key-123"
export NODE_ENV="development"
dotenv .env
PATH_add bin
PATH_add node_modules/.bin
direnv allow # required first time and after changes
Step 3: Per-Project Layouts
# .envrc — Use specific versions
use nvm 20
layout python3
Guidelines
- Always add .envrc to .gitignore — it contains secrets.
- Use .envrc.example (committed) as template.
- direnv unloads vars when you leave the directory — no env pollution.
