// This file contains an Express server that does two things:
//
// 1. During development, provide data APIs for the web app to consume
//
//     The development webpack-dev-server initiated via `npm start` can only serve
//     static files from the root project directory. This server provides two APIs
//     for dynamic data: listing AMP docs and retrieving contents of a single AMP doc.
//
//     For development, run `npm start`.
//     Then, in a **separate terminal shell**, run `node server.js`.
//
// 2. Testing the production build
//
//     `npm run build` builds the web app for production into the build/ folder.
//     This server also serves the content of that folder via express.static.
//
//     To test the prod build, run `npm run build && node server.js` and the navigate
//     to http://localhost:4000 on your web browser.

var express = require('express');
var path = require('path');
var pjson = require('./package.json');

// This port number must match that of `proxy` in `package.json`, which is used
// to redirect requests from the development server to the APIs in this file.
// See https://github.com/facebookincubator/create-react-app/blob/master/template/README.md#proxying-api-requests-in-development
var port = pjson.proxy ? parseInt(pjson.proxy.split(':')[2]) : 4000;
