express-pants's Introduction

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
