neutrino-middleware-env v7.4.0
Neutrino Environment Middleware
neutrino-middleware-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 v6.10+
- Yarn or npm client
- Neutrino v7
Installation
neutrino-middleware-env
can be installed via the Yarn or npm clients.
Yarn
❯ yarn add neutrino-middleware-env
npm
❯ npm install --save neutrino-middleware-env
Usage
neutrino-middleware-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('neutrino-middleware-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: ['neutrino-middleware-env']
};
// Usage with additional environment variables
module.exports = {
use: [
['neutrino-middleware-env', ['SECRET_KEY']]
]
};
This middleware optionally accepts an array of environment variables to additionally inject into source code.
Customization
neutrino-middleware-env
creates some conventions to make overriding the configuration easier once you are ready to
make changes.
