JSPM – @dotenvx/dotenvx@0.13.0

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.

Readme

a better dotenv–from the creator of dotenv.

run anywhere (cross-platform)
multi-environment
encrypted envs

Quickstart

Install and use it in code just like dotenv.

npm install @dotenvx/dotenvx --save

// index.js
require('@dotenvx/dotenvx').config()

console.log(`Hello ${process.env.HELLO}`)

Or install globally

brew install dotenvx/brew/dotenvx

other global ways to install

Installing globally as a cli unlocks dotenv for ANY language, framework, or platform. 💥

I am using (and recommending) this approach going forward. – motdotla

Run Anywhere

$ echo "HELLO=World" > .env
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

Multiple Environments

Create a .env.production file and use --env-file to 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
Hello production
> ^^

More examples

multiple `.env` files

$ echo "HELLO=local" > .env.local

$ echo "HELLO=World" > .env

$ dotenvx run --env-file=.env.local --env-file=.env -- node index.js
[dotenvx][info] loading env (1) from .env.local,.env
Hello local

`--overload` flag

$ echo "HELLO=local" > .env.local

$ echo "HELLO=World" > .env

$ dotenvx run --env-file=.env.local --env-file=.env --overload -- node index.js
[dotenvx][info] loading env (1) from .env.local,.env

`--verbose` flag

$ echo "HELLO=production" > .env.production

$ dotenvx run --env-file=.env.production --verbose -- node index.js
[dotenvx][verbose] injecting env from /path/to/.env.production
[dotenvx][verbose] HELLO set

`--debug` flag

$ echo "HELLO=production" > .env.production

$ dotenvx run --env-file=.env.production --debug -- node index.js
[dotenvx][debug] configuring options
[dotenvx][debug] {"envFile":[".env.production"]}
[dotenvx][verbose] injecting env from /path/to/.env.production

[dotenvx][verbose] HELLO set
[dotenvx][debug] HELLO set to production
[dotenvx][info] loading env (1) from .env.production
Hello production

`--quiet` flag

Use --quiet to suppress all output (except errors).

$ echo "HELLO=production" > .env.production

$ dotenvx run --env-file=.env.production --quiet -- node index.js
Hello production

`--log-level` flag

Set --log-level to whatever you wish. For example, to supress warnings (risky), set log level to error:
```
$ echo "HELLO=production" > .env.production

$ dotenvx run --env-file=.env.production --log-level=error -- node index.js
Hello production
```
Available log levels are error, warn, info, verbose, debug, silly

Encryption

Encrypt your secrets to a .env.vault file 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
Hello production
