koa-spa

Create a Single Page Application(SPA) server with koa. Just like what pushserve does.

The goal is simple, make all routes under your SPA send the same index.html, while keep assets files (css, js) under the same directory accessible.

This is only a koa middleware, so you can decorate the server with your own middlewares, or integrate this "pushState friendly" functionality into a normal server (with server side routing).

A custom 404 page is possible, too.

Example

var path_ = require('path');

var koa = require('koa');
var spa = require('koa-spa');

exports.startServer = function(port, path) {
  var routes = {};

  // collect available routes
  require('./app/routes')(spa.routeCollector(routes));

  var app = koa();
  app.use(spa(path_.join(__dirname, path), {
     index: 'index.html',
     routeBase: '/',
     routes: routes
  }));

  // assets file requests will not run through middlewares below,
  // but `index.html` requests will
  // app.use(detectLanguage());

  // add your custom 404 page
  app.use(function* () {
    // requests not matching the routes will have a status of 404 by now,
    // but the response it not yet sent
    if (this.status == 404) {
      res.body = 'Nothing Here.';
    }
  });

  app.listen(port);
};

If your are using something like brunch and Backbone.js, the app/routes.js required above would be your routes configuration for Backbones.js:

module.exports = function(match) {
  match('', 'home#index');
  match('login', 'account#login');
  match('logout', 'account#logout')
};
