Package Exports
- @dotenvx/dotenvx
- @dotenvx/dotenvx/src/lib/main.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@dotenvx/dotenvx) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Multiple Environments
Create a
.env.productionfile and use--env-fileto load it. It's straightforward, yet flexible.
$ echo "HELLO=production" > .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js
$ dotenvx run --env-file=.env.production -- node index.js
[dotenvx][info] loading env (1) from .env.production

Encryption
Encrypt your secrets to a
.env.vaultfile and load from it (recommended for production and ci).
$ echo "HELLO=World" > .env
$ echo "HELLO=production" > .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js
$ dotenvx encrypt
[dotenvx][info] encrypted to .env.vault (.env,.env.production)
[dotenvx][info] keys added to .env.keys (DOTENV_KEY_PRODUCTION,DOTENV_KEY_PRODUCTION)
$ DOTENV_KEY='<dotenv_key_production>' dotenvx run -- node index.js
[dotenvx][info] loading env (1) from encrypted .env.vault

Pre-commit
You can prevent .env files from being committed to code with this pre-commit hook.
Place this in .git/hooks/pre-commit
#!/bin/sh
dotenvx precommit --quiet
# Check dotenvx precommit exit status
if [ $? -ne 0 ]; then
echo "dotenvx pre-commit failed. run [dotenvx precommit] for more information"
exit 1
fi
exit 0Make sure to make it executable.
chmod +x .git/hooks/pre-commitYou can simulate the pre-commit hook by running dotenvx precommit locally.
