Secrets

Secret handler for Node.js 🗝️

Secret is a zero-dependency package to handle secrets in Node.js from a .env file into process.env. Inspired by dotenv.

Install

yarn add secrets

Usage

Create a .env file in the root directory of your project. It supports 3 types of .env files .env.json and .env.js

.env supports entries in the form of NAME=VALUE.

NODE_ENV=development
PORT=3000
SECRET=my_super_secret

.env.json supports JSON

{
  "NODE_ENV": "development",
  "PORT": 3000,
  "SECRET": "my_super_secret"
}

.env.js supports JavaScript

module.exports = {
  NODE_ENV: 'development',
  PORT: 3000,
  SECRET: 'my_super_secret',
}

That's it. As early as possible in your application, require secrets. process.env should have the keys and values you defined in your .env file.

// setups entries in process.env
import 'secrets' // or require('secrets')
...

// which can be access anywhere in your code
app.listen(process.env.PORT, function () {
  console.log('Server running on localhost:' + process.env.PORT)
})

Verify environment variables are loaded in process.env

secret.verify('PORT', 'SECRET') // throw error if it's missing

Babel Plugin

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: ['secrets/babel-plugin-secrets'],
}

Github Action

To create secret .env environment files on demands on your github actions checkout du5rte/create-secret-file

Location

Secrets should be place in the root of the project but it searches for .env files the same way node searches for node_modules folders, the closer to the root the higher the priority.

/Users/user/myProjects/myAwesomeProject/.env
/Users/user/myProjects/.env
/Users/user/.env
/Users/.env

Rules

The parsing engine currently supports the following rules:

• BASIC=basic becomes {BASIC: 'basic'}
• empty lines are skipped
• lines beginning with # are treated as comments
• empty values become empty strings (EMPTY= becomes {EMPTY: ''})
• single and double quoted values are escaped (SINGLE_QUOTE='quoted' becomes {SINGLE_QUOTE: "quoted"})
• new lines are expanded if in double quotes (MULTILINE="new\nline" becomes

{MULTILINE: 'new
line'}

• inner quotes are maintained (think JSON) (JSON={"foo": "bar"} becomes {JSON:"{\"foo\": \"bar\"}")

FAQ

Should I commit my secrets files?

No! 🙅‍♂️, do not commit your .env files! Adding a .gitignore file to your repository should be your first line of defense against accidentally leaking any secrets. read more
