env-path

Loads environment variables from a chosen .env file into process.env, using dotenv and dotenv-expand

Adds .env variables to process.env

package.json
"scripts": {
  "test"  : "env-path -p path/.env node app.js"
  "build" : "env-path -p path/.env.production, react-scripts build"
  "start" : "env-path -p otherPath/.env-file react-script start",
}

Installation

$ npm install env-path

Usage

Thanks to dotenv-expand, we can use variables inside our .env file.

See simple .env file under

API_KEY=key
PORT=3000
MONGO_DB=myDB
MONGO_URL=mongodb://localhost:27017/${MONGO_DB}
REACT_APP_VERSION=$npm_package_version

Run

Preloads dotenv and dotenv-expand. By doing this, you do not need to require and load dotenv and dotenv-expand in your application code.

Path

Specify a path using the -p flag:

$ env-path -p path/.env-file node app.js

package.json
"scripts": {
  "build"   : "env-path -p path/.env.production, react-scripts build"
  "start"   : "env-path -p path/.env-file react-script start",
  "start2"  : "env-path -p path/.env.development node app.js",
  "start3"  : "env-path -p path/otherFileName.env node app.js",
}

Without path

Works similar to dotenv's Preload See dotenv docs

$ env-path node app.js

package.json
"scripts": {
  "start"   : "env-path node app.js",
  "build"   : "env-path react-scripts build"
}
