Using Dotenv Vault with Edgio and Nuxt.js

Rishi Raj Jain

Learn how to make Edgio, Nuxt.js, and Dotenv Vault work together in a simple web app. This tutorial assumes you are already familiar with .env files and know how to sync them.

You can find a complete example repo here.

Initialize a Nuxt(2) App

npx create-nuxt-app edgio-dotenv-vault-nuxt-example

Install Edgio CLI

npm i -g @edgio/cli

Integrate Edgio with Nuxt(2)

edgio init

Install dotenv-vault

# Install as dep and not devDep
npm install dotenv-vault

Update nuxt.config.js to use dotenv-vault

// Filename: nuxt.config.js


export default {
  // Auto import components:
  components: true,
  // Modules for dev and build (recommended):
  buildModules: [["@edgio/nuxt/module", { edgioSourceMaps: true }]],

Update edgio.config.js to include .env.vault

// Filename: edgio.config.js

"use strict"

module.exports = {
  connector: "@edgio/nuxt",

  // Set to true to include all packages listed in the dependencies property of package.json when deploying to Edgio.
  includeNodeModules: true,

  // Allows you to include additional resources in the bundle that is deployed to Edgio’s serverless JS workers.
  // Keys are globs, value can be a boolean or string. This is typically used to ensure that resources
  // that need to be dynamically required at runtime such as build manifests for server-side rendering
  // or other config files are present in the cloud.
  includeFiles: {
    ".env.vault": true,


Run dotenv-vault new

Open terminal, enter your project’s root directory (where you keep your .env file), and run dotenv-vault new.

npx dotenv-vault new

Run dotenv-vault login

Next, authenticate your machine by running dotenv-vault login.

npx dotenv-vault login

Push your .env to the dotenv account

Return one last time to terminal and run dotenv-vault push.

This will securely push your .env file to dotenv-vault. Each time you change your .env file, run dotenv-vault push.

npx dotenv-vault push

Congratulations 🎉, you just pushed (and secured) your first .env file in dotenv-vault.

Build the vault before running dev, build and production mode

Make sure you are logged in and in sync with your Vault first then run npx dotenv-vault build from CLI in your project root.

This will build an encrypted .env.vault file that serves as a unique identifier for your project in Dotenv.

Inside it you will find the public keys for every environment you have setup and must be committed to source.

npx dotenv-vault build

Fetch the dotenv-vault keys

With the Vault successfully built, you now can fetch the .env.vault decryption keys for each environment in the Vault project.

Running npx dotenv-vault keys production, for example, will return the production key and so will development and ci respectively.

npx dotenv-vault keys production
remote:   Listing .env.vault decryption keys... done

Okay, what just happened?

So now realize that you've created three files:

  • .env: The file containing all your secret variables that you pushed to dotenv-vault via npx dotenv-vault push. This file is not to be pushed in git commit(s).

  • That contains the key that uniquely identifies the user of the dotenv-vault project. This file is not to be pushed in git commit(s).

  • .env.vault: The file that contains the hashes to dotenv-vault's four mode: development, ci, staging and production. This file is to be pushed in git commit(s).

  • You probably still haven't realized that dotenv-vault has stages of secrets. For example, look at the gray button on the top right corner in the screenshot below that says 'development'. dotenv-vault example repo

To get keys for the development environment, one needs to run:

npx dotenv-vault keys development
remote:   Listing .env.vault decryption keys... done


Requirements to run dotenv-vault

What you get above is what we'll be referred to as DOTENVKEY in the guide. To ensure dotenv-vault properly, in any mode, you'd require the DOTENVKEY environment variable set, and the .env.vault file present in the root directory.

Using dotenv-vault during edgio dev (Edgio's dev mode)

Using .env at the root directory

Create a .env in your system which contains the following:

# .env


and then run the edgio's dev mode via:

edgio dev

Setting the variable with the CLI command

DOTENV_KEY=dotenv:// edgio dev

Using dotenv-vault during edgio build (Edgio's build mode)

Using .env at the root directory

Create a .env in your system which contains the following:

# .env


and then run the edgio's build mode via:

edgio build

Setting the variable with the CLI command

DOTENV_KEY=dotenv:// edgio build

Deploy To Edgio

To use dotenv-vault while deploying to Edgio for the first time, if you need the variables during the build time, deploy with:

DOTENV_KEY=dotenv:// edgio deploy

Using dotenv-vault during runtime (server-side)

To use the dotenv-vault during the runtime with Edgio, add an environment variable by following the guide here named DOTENV_KEY. Example DOTENV_KEY added to Edgio's environment

Once you've created an env variable in the Edgio console, for future builds edgio deploy will include the environment variable(s) added to the console during the build time by itself.
