Some nice pants for your Express App to wear

A semi-opinionated framework for setting up Express apps.

Install

$ npm install --save express-pants

Usage

const createApp = require('express-pants')

const runApp = createApp((app, opts = {}) => {
  // Handle app errors
  app.on('error', console.error)

  // Load in your routes
  app.get('/', (req, res) => {
    res.send(`Hello ${opts.message}!`)
  })
})

// Start the app
runApp({
  port: 8080,
  message: 'World'
}).then(({ app, server }) => {
  const addr = server.address()
  // Log is a Pino logger
  app.get('log').info(`Server started at http://${app.get('host')}:${addr.port}`)
})

What does it do?

This package sets up common requirements for running an Express app in production with the goal of reducing boilerplate in your applications. Here is a list of some of those things:

• Uses next gen Express (5.0.0-alpha.7 at the time of publishing this)
  • See the GitHub PR for 5.0 for details
  • New and improved path-to-regex
  • Router with basic promise support
• Express app settings
  • Remove x-powered-by header
  • Sets query string parsing to simple (faster, more secure, planned default for 5.0)
• Set process title (nice for identifying your server process)
• Catch, report and exit on uncaughtException and unhandledRejection
• Handle and report server clientErrors
• Parses JSON bodies
• Parses cookies (off by default, turn on by passing options.parseCookies)
• Helmet (turned off by default, but turn on with options.helmet)
• Pino logging with pino-http
