Middleware.md

Middleware

nwb provides middleware for serving a hot reloading app from your own server.

This gives you the same setup as if you'd run the nwb serve command, using your app's nwb.config.js file for configuration as usual.

Express 4.x Middleware

Middleware for Express 4.x for developing apps can be imported from 'nwb/express'.

See the nwb-react-tutorial project for an example of using it.

API

middleware(express, options: Object)

express

Your app's version of the Express module must be passed as the first argument.

options

• config - path to a config file [default: nwb.config.js]
• entry - entry point for the app [default: src/index.js]
• install - automatically install missing npm dependencies [default: false]
• reload - reload the page if Hot Module Replacement is unsuccessful [default: false]

Example

Here's a minimal express server which serves up an app:

var express = require('express')

var app = express()

app.use(require('nwb/express')(express))

app.use(express.static('public'))

app.listen(3000, function(err) {
  if (err) {
    console.error('error starting server:')
    console.error(err.stack)
    process.exit(1)
  }
  console.log('server listening at http://localhost:3000')
})
