@neutrinojs/env v8.3.0

Neutrino Environment Middleware

@neutrinojs/env is Neutrino middleware for injecting environment variable definitions into source code at process.env. You can use this to make a custom environment variable (e.g. an API server backend to use) available inside your project. Always injects process.env.NODE_ENV, unless overridden.

Requirements

• Node.js v6 LTS, v8, v9
• Yarn v1.2.1+, or npm v5.4+
• Neutrino v8

Installation

@neutrinojs/env can be installed via the Yarn or npm clients.

Yarn

❯ yarn add @neutrinojs/env

npm

❯ npm install --save @neutrinojs/env

Usage

@neutrinojs/env can be consumed from the Neutrino API, middleware, or presets. Require this package and plug it into Neutrino:

// Using function middleware format
const env = require('@neutrinojs/env');

// Use with default options
neutrino.use(env);

// Usage with additional environment variables
neutrino.use(env, ['SECRET_KEY']);

// Using object or array middleware format

// Use with default options
module.exports = {
  use: ['@neutrinojs/env']
};

// Usage with additional environment variables
module.exports = {
  use: [
    ['@neutrinojs/env', ['SECRET_KEY']]
  ]
};

This middleware optionally accepts an array of environment variables to additionally inject into source code.

Customization

@neutrinojs/env creates some conventions to make overriding the configuration easier once you are ready to make changes.
