### Quickstart [![npm version](https://img.shields.io/npm/v/@dotenvx/dotenvx.svg)](https://www.npmjs.com/package/@dotenvx/dotenvx) [![downloads](https://img.shields.io/npm/dw/@dotenvx/dotenvx)](https://www.npmjs.com/package/@dotenvx/dotenvx) [![test suite](https://img.shields.io/endpoint?url=https://gist.githubusercontent.com/motdotenv/bb76445765a9731e7d824a6efdf53524/raw/dotenvxTestCount.json)](https://github.com/dotenvx/dotenvx/tree/main/tests) 

Install and use it in code just like `dotenv`.

```sh
npm install @dotenvx/dotenvx --save
```
```js
// index.js
require('@dotenvx/dotenvx').config()
// or import '@dotenvx/dotenvx/config' // for esm

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

 

or install globally - *unlocks dotenv for any language, framework, or platform!*

## Multiple Environments

> Create a `.env.production` file and use `-f` to load it. It's straightforward, yet flexible.
```sh
$ echo "HELLO=production" > .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ dotenvx run -f .env.production -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env.production
Hello production
> ^^
```

More examples

<details><summary>multiple `.env` files</summary><br>

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

$ echo "HELLO=World" > .env

$ dotenvx run -f .env.local -f .env -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env.local,.env
Hello local
```

Note subsequent files do NOT override pre-existing variables defined in previous files or env. This follows historic principle. For example, above `local` wins – from the first file.

</details>

<details><summary>`--overload` flag</summary><br>

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

$ echo "HELLO=World" > .env

$ dotenvx run -f .env.local -f .env --overload -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env.local,.env
Hello World
```

Note that with `--overload` subsequent files DO override pre-existing variables defined in previous files.
</details>
<details><summary>`--verbose` flag</summary><br>

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

$ dotenvx run -f .env.production --verbose -- node index.js
[dotenvx][verbose] injecting env from /path/to/.env.production
[dotenvx][verbose] HELLO set
[dotenvx@1.X.X] injecting env (1) from .env.production
Hello production
```

</details>
<details><summary>`--debug` flag</summary><br>

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

$ dotenvx run -f .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][debug] reading env from /path/to/.env.production
[dotenvx][debug] parsing env from /path/to/.env.production
[dotenvx][debug] {"HELLO":"production"}
[dotenvx][debug] writing env from /path/to/.env.production
[dotenvx][verbose] HELLO set
[dotenvx][debug] HELLO set to production
[dotenvx@1.X.X] injecting env (1) from .env.production
Hello production
```

</details>
<details><summary>`--quiet` flag</summary><br>

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

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

$ dotenvx run -f .env.production --quiet -- node index.js
Hello production
```

</details>
<details><summary>`--log-level` flag</summary><br>

Set `--log-level` to whatever you wish. For example, to suppress warnings (risky), set log level to `error`:

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

$ dotenvx run -f .env.production --log-level=error -- node index.js
Hello production
```

Available log levels are `error, warn, info, verbose, debug, silly`

</details>
<details><summary>`--convention` flag</summary><br>

Load envs using [Next.js' convention](https://nextjs.org/docs/pages/building-your-application/configuring/environment-variables#environment-variable-load-order) or [dotenv-flow convention](https://www.npmjs.com/package/dotenv-flow). Set `--convention` to `nextjs` or `flow`:

```sh
$ echo "HELLO=development local" > .env.development.local
$ echo "HELLO=local" > .env.local
$ echo "HELLO=development" > .env.development
$ echo "HELLO=env" > .env

$ dotenvx run --convention=nextjs -- node index.js
Hello development local

$ dotenvx run --convention=flow -- node index.js
Hello development local
```

(more conventions available upon request)

</details>

&nbsp;

## Encryption

> Add encryption to your `.env` files with a single command. Use `dotenvx encrypt`.

```sh
$ dotenvx encrypt
✔ encrypted (.env)
```

[![encrypted .env](https://github.com/user-attachments/assets/46dfe1a7-a027-4d80-9207-789eccc325dc)](https://dotenvx.com)

> A `DOTENV_PUBLIC_KEY` (encryption key) and a `DOTENV_PRIVATE_KEY` (decryption key) are generated using the same public-key cryptography as [Bitcoin](https://en.bitcoin.it/wiki/Secp256k1).

More examples

<details><summary>`.env`</summary><br>

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

$ dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env
Hello World
```

</details>
<details><summary>`.env.production`</summary><br>

```sh
$ echo "HELLO=Production" > .env.production
$ dotenvx encrypt -f .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ DOTENV_PRIVATE_KEY_PRODUCTION="<.env.production private key>" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env.production
Hello Production
```

Note the `DOTENV_PRIVATE_KEY_PRODUCTION` ends with `_PRODUCTION`. This instructs `dotenvx run` to load the `.env.production` file.

</details>
<details><summary>`.env.ci`</summary><br>

```sh
$ echo "HELLO=Ci" > .env.ci
$ dotenvx encrypt -f .env.ci
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ DOTENV_PRIVATE_KEY_CI="<.env.ci private key>" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env.ci
Hello Ci
```

Note the `DOTENV_PRIVATE_KEY_CI` ends with `_CI`. This instructs `dotenvx run` to load the `.env.ci` file. See the pattern?

</details>
<details><summary>combine multiple encrypted .env files</summary><br>

```sh
$ dotenvx set HELLO World -f .env
$ dotenvx set HELLO Production -f .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ DOTENV_PRIVATE_KEY="<.env private key>" DOTENV_PRIVATE_KEY_PRODUCTION="<.env.production private key>" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (3) from .env, .env.production
Hello World
```

Note the `DOTENV_PRIVATE_KEY` instructs `dotenvx run` to load the `.env` file and the `DOTENV_PRIVATE_KEY_PRODUCTION` instructs it to load the `.env.production` file. See the pattern?

</details>
<details><summary>combine multiple encrypted .env files for monorepo</summary><br>

```sh
$ mkdir app1
$ mkdir app2
$ dotenvx set HELLO app1 -f app1/.env.ci
$ dotenvx set HELLO app2 -f app2/.env.ci
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ DOTENV_PRIVATE_KEY_CI="<app1/privat ci key>,<app2/private ci key>" dotenvx run -f app1/.env.ci -f app2/.env.ci -- node index.js
[dotenvx@1.X.X] injecting env (2) from app1/.env.ci,app2/.env.ci
Hello app1

$ DOTENV_PRIVATE_KEY_CI="<app1/privat ci key>,<app2/private ci key>" dotenvx run -f app1/.env.ci -f app2/.env.ci --overload -- node index.js
[dotenvx@1.X.X] injecting env (2) from app1/.env.ci,app2/.env.ci
Hello app2
```

Note the `DOTENV_PRIVATE_KEY_CI` (and any `DOTENV_PRIVATE_KEY*`) can take multiple private keys by simply comma separating them.

### CLI 📟

Advanced CLI commands.

<details><summary>`run` - Variable Expansion</summary><br>

Reference and expand variables already on your machine for use in your .env file.

```ini
# .env
USERNAME="username"
DATABASE_URL="postgres://${USERNAME}@localhost/my_database"
```
```js
// index.js
console.log('DATABASE_URL', process.env.DATABASE_URL)
```
```sh
$ dotenvx run --debug -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env
DATABASE_URL postgres://username@localhost/my_database
```

</details>
<details><summary>`run` - Default Values</summary><br>

Use default values when environment variables are unset or empty.

```ini
# .env
# Default value syntax: use value if set, otherwise use default
DATABASE_HOST=${DB_HOST:-localhost}
DATABASE_PORT=${DB_PORT:-5432}

# Alternative syntax (no colon): use value if set, otherwise use default
API_URL=${API_BASE_URL-https://api.example.com}
```
```js
// index.js
console.log('DATABASE_HOST', process.env.DATABASE_HOST)
console.log('DATABASE_PORT', process.env.DATABASE_PORT)
console.log('API_URL', process.env.API_URL)
```
```sh
$ dotenvx run --debug -- node index.js
[dotenvx@1.X.X] injecting env (3) from .env
DATABASE_HOST localhost
DATABASE_PORT 5432
API_URL https://api.example.com
```

</details>
<details><summary>`run` - Alternate Values</summary><br>

Use alternate values when environment variables are set and non-empty.

```ini
# .env
NODE_ENV=production

# Alternate value syntax: use alternate if set and non-empty, otherwise empty
DEBUG_MODE=${NODE_ENV:+false}
LOG_LEVEL=${NODE_ENV:+error}

# Alternative syntax (no colon): use alternate if set, otherwise empty  
CACHE_ENABLED=${NODE_ENV+true}
```
```js
// index.js
console.log('NODE_ENV', process.env.NODE_ENV)
console.log('DEBUG_MODE', process.env.DEBUG_MODE)
console.log('LOG_LEVEL', process.env.LOG_LEVEL)
console.log('CACHE_ENABLED', process.env.CACHE_ENABLED)
```
```sh
$ dotenvx run --debug -- node index.js
[dotenvx@1.X.X] injecting env (4) from .env
NODE_ENV production
DEBUG_MODE false
LOG_LEVEL error
CACHE_ENABLED true
```

</details>
<details><summary>`run` - Interpolation Syntax Summary (Variable Expansion, Default/Alternate Values)</summary><br>

Complete reference for variable interpolation patterns supported by dotenvx:

```ini
# .env
DEFINED_VAR=hello
EMPTY_VAR=
# UNDEFINED_VAR is not set

# Default value syntax - use variable if set/non-empty, otherwise use default
TEST1=${DEFINED_VAR:-fallback}     # Result: "hello"
TEST2=${EMPTY_VAR:-fallback}       # Result: "fallback"  
TEST3=${UNDEFINED_VAR:-fallback}   # Result: "fallback"

# Default value syntax (no colon) - use variable if set, otherwise use default
TEST4=${DEFINED_VAR-fallback}      # Result: "hello"
TEST5=${EMPTY_VAR-fallback}        # Result: "" (empty, but set)
TEST6=${UNDEFINED_VAR-fallback}    # Result: "fallback"

# Alternate value syntax - use alternate if variable is set/non-empty, otherwise empty
TEST7=${DEFINED_VAR:+alternate}    # Result: "alternate"
TEST8=${EMPTY_VAR:+alternate}      # Result: "" (empty)
TEST9=${UNDEFINED_VAR:+alternate}  # Result: "" (empty)

# Alternate value syntax (no colon) - use alternate if variable is set, otherwise empty  
TEST10=${DEFINED_VAR+alternate}    # Result: "alternate"
TEST11=${EMPTY_VAR+alternate}      # Result: "alternate" (empty but set)
TEST12=${UNDEFINED_VAR+alternate}  # Result: "" (empty)
```

**Key differences:**
- `:-` vs `-`: The colon makes empty values trigger the fallback
- `:+` vs `+`: The colon makes empty values not trigger the alternate  
- Default syntax (`-`): Use variable value or fallback
- Alternate syntax (`+`): Use alternate value or empty string

</details>
<details><summary>`run` - Command Substitution</summary><br>

Add the output of a command to one of your variables in your .env file.

```ini
# .env
DATABASE_URL="postgres://$(whoami)@localhost/my_database"
```
```js
// index.js
console.log('DATABASE_URL', process.env.DATABASE_URL)
```
```sh
$ dotenvx run --debug -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env
DATABASE_URL postgres://yourusername@localhost/my_database
```

</details>
<details><summary>`run` - Shell Expansion</summary><br>

Prevent your shell from expanding inline `$VARIABLES` before dotenvx has a chance to inject it. Use a subshell.

```sh
$ dotenvx run --env="HELLO=World" -- sh -c 'echo Hello $HELLO'
Hello World
```

</details>
<details><summary>`run` - Multiline</summary><br>

Dotenvx supports multiline values. This is particularly useful in conjunction with Docker - which [does not support multiline values](https://stackoverflow.com/questions/50299617/set-multiline-environment-variable-with-dockerfile/79578348#79578348).

<details><summary>`run` - Contextual Help</summary><br>

Unlike other dotenv libraries, dotenvx attempts to unblock you with contextual help.

For example, when missing a custom .env file:

```sh
$ dotenvx run -f .env.missing -- echo $HELLO
[MISSING_ENV_FILE] missing .env.missing file (/Users/scottmotte/Code/dotenvx/playground/apr-16/.env.missing)
[MISSING_ENV_FILE] https://github.com/dotenvx/dotenvx/issues/484 and re-run [dotenvx run -- echo]
```

or when missing a KEY:

```sh
$ echo "HELLO=World" > .env
$ dotenvx get GOODBYE
[MISSING_KEY] missing GOODBYE key
```

</details>
<details><summary>`run` - multiple `-f` flags</summary><br>

Compose multiple `.env` files for environment variables loading, as you need.

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

$ dotenvx run -f .env.local -f .env -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env.local, .env
Hello local
```

Note subsequent files do NOT override pre-existing variables defined in previous files or env. This follows historic principle. For example, above `local` wins – from the first file.

</details>
<details><summary>`run --env HELLO=String`</summary><br>

Set environment variables as a simple `KEY=value` string pair.

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

$ dotenvx run --env HELLO=String -f .env -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env, and --env flag
Hello String
```

</details>
<details><summary>`run --overload`</summary><br>

Override existing env variables. These can be variables already on your machine or variables loaded as files consecutively. The last variable seen will 'win'.

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

$ dotenvx run -f .env.local -f .env --overload -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env.local, .env
Hello World
```

Note that with `--overload` subsequent files DO override pre-existing variables defined in previous files.

</details>
<details><summary>`run` - Environment Variable Precedence (Container/Cloud Deployments)</summary><br>

When deploying applications in containers or cloud environments, you often need to override specific environment variables at runtime without modifying committed `.env` files. By default, dotenvx follows the historic dotenv principle: **environment variables already present take precedence over `.env` files**.

```sh
# .env.prod contains: MODEL_REGISTRY=registry.company.com/models/v1
$ echo "MODEL_REGISTRY=registry.company.com/models/v1" > .env.prod
$ echo "console.log('MODEL_REGISTRY:', process.env.MODEL_REGISTRY)" > app.js

# Without environment variable set - uses .env.prod value
$ dotenvx run -f .env.prod -- node app.js
MODEL_REGISTRY: registry.company.com/models/v1

# With environment variable set (e.g., via Azure Container Service) - environment variable takes precedence
$ MODEL_REGISTRY=registry.azure.com/models/v2 dotenvx run -f .env.prod -- node app.js
MODEL_REGISTRY: registry.azure.com/models/v2

# To force .env.prod to override environment variables, use --overload
$ MODEL_REGISTRY=registry.azure.com/models/v2 dotenvx run -f .env.prod --overload -- node app.js
MODEL_REGISTRY: registry.company.com/models/v1
```

**For container deployments:** Set environment variables through your cloud provider's UI/configuration (Azure Container Service, AWS ECS, etc.) to override specific values from committed `.env` files without rebuilding your application.

</details>
<details><summary>`DOTENV_PRIVATE_KEY=key run`</summary><br>

Decrypt your encrypted `.env` by setting `DOTENV_PRIVATE_KEY` before `dotenvx run`.

```sh
$ touch .env
$ dotenvx set HELLO encrypted
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

# check your .env.keys files for your privateKey
$ DOTENV_PRIVATE_KEY="122...0b8" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env
Hello encrypted
```

</details>
<details><summary>`DOTENV_PRIVATE_KEY_PRODUCTION=key run`</summary><br>

Decrypt your encrypted `.env.production` by setting `DOTENV_PRIVATE_KEY_PRODUCTION` before `dotenvx run`. Alternatively, this can be already set on your server or cloud provider.

```sh
$ touch .env.production
$ dotenvx set HELLO "production encrypted" -f .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

# check .env.keys for your privateKey
$ DOTENV_PRIVATE_KEY_PRODUCTION="122...0b8" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env.production
Hello production encrypted
```

Note the `DOTENV_PRIVATE_KEY_PRODUCTION` ends with `_PRODUCTION`. This instructs dotenvx run to load the `.env.production` file.

</details>
<details><summary>`DOTENV_PRIVATE_KEY_CI=key dotenvx run`</summary><br>

Decrypt your encrypted `.env.ci` by setting `DOTENV_PRIVATE_KEY_CI` before `dotenvx run`. Alternatively, this can be already set on your server or cloud provider.

```sh
$ touch .env.ci
$ dotenvx set HELLO "ci encrypted" -f .env.ci
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

# check .env.keys for your privateKey
$ DOTENV_PRIVATE_KEY_CI="122...0b8" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (2) from .env.ci
Hello ci encrypted
```

Note the `DOTENV_PRIVATE_KEY_CI` ends with `_CI`. This instructs dotenvx run to load the `.env.ci` file. See the pattern?

</details>
<details><summary>`DOTENV_PRIVATE_KEY=key DOTENV_PRIVATE_KEY_PRODUCTION=key run` - Combine Multiple</summary><br>

Decrypt your encrypted `.env` and `.env.production` files by setting `DOTENV_PRIVATE_KEY` and `DOTENV_PRIVATE_KEY_PRODUCTION` before `dotenvx run`. 

```sh
$ touch .env
$ touch .env.production
$ dotenvx set HELLO encrypted
$ dotenvx set HELLO "production encrypted" -f .env.production
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

# check .env.keys for your privateKeys
$ DOTENV_PRIVATE_KEY="122...0b8" DOTENV_PRIVATE_KEY_PRODUCTION="122...0b8" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (3) from .env, .env.production
Hello encrypted

$ DOTENV_PRIVATE_KEY_PRODUCTION="122...0b8" DOTENV_PRIVATE_KEY="122...0b8" dotenvx run -- node index.js
[dotenvx@1.X.X] injecting env (3) from .env.production, .env
Hello production encrypted
```

Compose any encrypted files you want this way. As long as a `DOTENV_PRIVATE_KEY_${environment}` is set, the values from `.env.${environment}` will be decrypted at runtime.

</details>
<details><summary>`run --verbose`</summary><br>

Set log level to `verbose`. ([log levels](https://docs.npmjs.com/cli/v8/using-npm/logging#setting-log-levels))

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

$ dotenvx run -f .env.production --verbose -- node index.js
loading env from .env.production (/path/to/.env.production)
HELLO set
[dotenvx@1.X.X] injecting env (1) from .env.production
Hello production
```

</details>
<details><summary>`run --debug`</summary><br>

Set log level to `debug`. ([log levels](https://docs.npmjs.com/cli/v8/using-npm/logging#setting-log-levels))

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

$ dotenvx run -f .env.production --debug -- node index.js
process command [node index.js]
options: {"env":[],"envFile":[".env.production"]}
loading env from .env.production (/path/to/.env.production)
{"HELLO":"production"}
HELLO set
HELLO set to production
[dotenvx@1.X.X] injecting env (1) from .env.production
executing process command [node index.js]
expanding process command to [/opt/homebrew/bin/node index.js]
Hello production
```

</details>
<details><summary>`run --quiet`</summary><br>

Use `--quiet` to suppress all output (except errors). ([log levels](https://docs.npmjs.com/cli/v8/using-npm/logging#setting-log-levels))

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

$ dotenvx run -f .env.production --quiet -- node index.js
Hello production
```

</details>
<details><summary>`run --log-level`</summary><br>

Set `--log-level` to whatever you wish. For example, to suppress warnings (risky), set log level to `error`:

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

$ dotenvx run -f .env.production --log-level=error -- node index.js
Hello production
```

Available log levels are `error, warn, info, verbose, debug, silly` ([source](https://docs.npmjs.com/cli/v8/using-npm/logging#setting-log-levels))

</details>
<details><summary>`run --strict`</summary><br>

Exit with code `1` if any errors are encountered - like a missing .env file or decryption failure.

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

$ dotenvx run -f .env.missing --strict -- node index.js
[MISSING_ENV_FILE] missing .env.missing file (/path/to/.env.missing)
[MISSING_ENV_FILE] ? add one with [echo "HELLO=World" > .env.missing]
```

This can be useful in `ci` scripts where you want to fail the ci if your `.env` file could not be decrypted at runtime.

</details>
<details><summary>`run --ignore`</summary><br>

Ignore errors like `MISSING_ENV_FILE`.

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

$ dotenvx run -f .env.missing --ignore=MISSING_ENV_FILE -- node index.js
...
```

</details>
<details><summary>`run --convention=nextjs`</summary><br>

Load envs using [Next.js' convention](https://nextjs.org/docs/pages/building-your-application/configuring/environment-variables#environment-variable-load-order). Set `--convention` to `nextjs`:

```sh
$ echo "HELLO=development local" > .env.development.local
$ echo "HELLO=local" > .env.local
$ echo "HELLO=development" > .env.development
$ echo "HELLO=env" > .env
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ dotenvx run --convention=nextjs -- node index.js
[dotenvx@1.X.X] injecting env (1) from .env.development.local, .env.local, .env.development, .env
Hello development local
```

(more conventions available upon request)

</details>
<details><summary>`run --convention=flow`</summary><br>

Load envs using [dotenv-flow's convention](https://www.npmjs.com/package/dotenv-flow). Set `--convention` to `flow`:

```sh
$ echo "HELLO=development local" > .env.development.local
$ echo "HELLO=development" > .env.development
$ echo "HELLO=local" > .env.local
$ echo "HELLO=env" > .env
$ echo "console.log('Hello ' + process.env.HELLO)" > index.js

$ NODE_ENV=development dotenvx run --convention=flow -- node index.js 
[dotenvx@1.X.X] injecting env (1) from .env.development.local, .env.development, .env.local, .env
Hello development local
```

Further, we recommend using `DOTENV_ENV` over `NODE_ENV`– as `dotenvx` works everywhere, not just node.

```sh
$ DOTENV_ENV=development dotenvx run --convention=flow -- node index.js 
[dotenvx@1.X.X] injecting env (1) from .env.development.local, .env.development, .env.local, .env
Hello development local
```

</details>
<details><summary>`run -fk`</summary><br>

Further, we recommend using `DOTENV_ENV` over `NODE_ENV`– as `dotenvx` works everywhere, not just node.

```sh
$ DOTENV_ENV=development dotenvx get HELLO --convention=flow
development local
```

</details>
<details><summary>`get` (json)</summary><br>

Return a json response of all key/value pairs in a `.env` file.

```

This can be useful when combined with `env` on the command line.

```
$ echo "console.log('Hello ' + process.env.KEY + ' ' + process.env.HELLO)" > index.js
$ env $(dotenvx get --format=shell) node index.js
Hello value World
```

or with `export`.

```

Return an `eval`-ready shell formatted response of all key/value pairs in a `.env` file.

```sh
$ echo "HELLO=World" > .env
$ echo "KEY=value" >> .env

$ dotenvx get --format eval
HELLO="World"
KEY="value"
```

Note that this exports newlines and quoted strings.

This can be useful for more complex .env values (spaces, escaped characters, quotes, etc) combined with `eval` on the command line.

```sh
$ echo "console.log('Hello ' + process.env.KEY + ' ' + process.env.HELLO)" > index.js
$ eval $(dotenvx get --format=eval) node index.js
Hello value World

## Whitepaper

> **Dotenvx: Reducing Secrets Risk with Cryptographic Separation**
>
> Abstract. An ideal secrets solution would not only centralize secrets but also contain the fallout of a breach. While secrets managers offer centralized storage and distribution, their design creates a large blast radius, risking exposure of thousands or even millions of secrets. We propose a solution that reduces the blast radius by splitting secrets management into two distinct components: an encrypted secrets file and a separate decryption key.

## FAQ

#### How does encryption work?

Dotenvx uses Elliptic Curve Integrated Encryption Scheme (ECIES) to encrypt each secret with a unique ephemeral key, while ensuring it can be decrypted using a long-term private key.

When you initialize encryption, a DOTENV_PUBLIC_KEY (encryption key) and DOTENV_PRIVATE_KEY (decryption key) are generated. The DOTENV_PUBLIC_KEY is used to encrypt secrets, and the DOTENV_PRIVATE_KEY is securely stored in your cloud secrets manager or .env.keys file.

Your encrypted .env file is then safely committed to code. Even if the file is exposed, secrets remain protected since decryption requires the separate DOTENV_PRIVATE_KEY, which is never stored alongside it. Read [the whitepaper](https://dotenvx.com/dotenvx.pdf?v=README) for more details.

#### Is it safe to commit an encrypted .env file to code?

Yes. Dotenvx encrypts secrets using AES-256 with ephemeral keys, ensuring that even if the encrypted .env file is exposed, its contents remain secure. The encryption keys themselves are protected using Secp256k1 elliptic curve cryptography, which is widely used for secure key exchange in technologies like Bitcoin.

This means that every secret in the .env file is encrypted with a unique AES-256 key, and that key is further encrypted using a public key (Secp256k1). Even if an attacker obtains the encrypted .env file, they would still need the corresponding private key—stored separately in a secrets manager—to decrypt anything.

Breaking this encryption would require brute-forcing both AES-256 and elliptic curve cryptography, which is computationally infeasible with current technology. Read [the whitepaper](https://dotenvx.com/dotenvx.pdf?v=README) for more details.

#### Why am I getting the error `node: .env: not found`?

You are using Node 20 or greater and it adds a differing implementation of `--env-file` flag support. Rather than warn on a missing `.env` file (like dotenv has historically done), it raises an error: `node: .env: not found`.

This fix is easy. Replace `--env-file` with `-f`.

```bash
# from this:
./node_modules/.bin/dotenvx run --env-file .env -- yourcommand
# to this:
./node_modules/.bin/dotenvx run -f .env -- yourcommand
```

#### What happened to the `.env.vault` file?

I've decided we should sunset it as a technological solution to this.

The `.env.vault` file got us far, but it had limitations such as:

* *Pull Requests* - it was difficult to tell which key had been changed
* *Security* - there was no mechanism to give a teammate the ability to encrypt without also giving them the ability to decrypt. Sometimes you just want to let a contractor encrypt a new value, but you don't want them to know the rest of the secrets.
* *Conceptual* - it takes more mental energy to understand the `.env.vault` format. Encrypted values inside a `.env` file is easier to quickly grasp.
* *Combining Multiple Files* - there was simply no mechanism to do this well with the `.env.vault` file format.

That said, the `.env.vault` tooling will still stick around for at least 1 year under `dotenvx vault` parent command. I'm still using it in projects as are many thousands of other people.

#### How do I migrate my `.env.vault` file(s) to encrypted `.env` files?

Run `$ dotenvx ext vault migrate` and follow the instructions.
