Basic Koa API and Web Server

1_Koa API and Webserver

This is my basic starting point for any koa server. Mostly for module development with frontend components

app.js

var koa = require('koa');
var app = koa();
var route = require('koa-route');
var send = require('koa-send');


var db = {
  tobi: { name: 'tobi', species: 'ferret' },
  loki: { name: 'loki', species: 'ferret' },
  jane: { name: 'jane', species: 'ferret' }
};


app.use(route.get('/', index));
app.use(route.get('/pets', list));
app.use(route.get('/pets/:name', show));

app.listen(3000);
console.log('listening on port 3000');



function* index(){
  yield send(this, '/index.html', { root: __dirname });
}

function* list(){
  var names = Object.keys(db);
  this.body = 'pets: ' + names.join(', ');
}

function* show(name){
  var pet = db[name];
  if (!pet) return this.throw('cannot find that pet', 404);
  this.body = pet.name + ' is a ' + pet.species;
}

Gulpfile.js

var gulp        = require('gulp');
var browserSync = require('browser-sync');
var reload      = browserSync.reload;
var nodemon = require('nodemon');


gulp.task('nodemon', function () {
  return nodemon({ script: 'example/app.js', ext: 'html js' })
  .on('restart', function () {
    console.log('restarted!')
  })
})

gulp.task('browser-sync', ['nodemon'], function() {
  browserSync({
    proxy: "localhost:3000",  // local node app address
    port: 4000,  // use *different* port than above
    notify: true
  });
});

gulp.task('nodemon', function (cb) {
  var called = false;
  return nodemon({
    script: 'example/app.js',
    ignore: [
    'Gulpfile.js',
    'node_modules/'
    ]
  })
  .on('start', function () {
    if (!called) {
      called = true;
      cb();
    }
  })
  .on('restart', function () {
    setTimeout(function () {
      reload({ stream: false });
    }, 1000);
  });
});

gulp.task('default', ['browser-sync'], function () {
  gulp.watch(['example/**/*.html'], reload);
  gulp.watch(['example/**/*.js'], reload);
  gulp.watch(['index.js'], ['bundle']);
  gulp.watch(['example/**/*.css'], reload);
});
gulp.task('test', [], function () {
});
gulp.task('deploy', [], function () {
});
