Start and call Ruby HTTP server in the same script

由 落爺英雄遲暮 提交于 2019-11-30 20:46:43
问题 I wonder how I could start a Ruby Rack application (such as Sinatra) and call it with Net::HTTP or similar in the same script. Of couse I could do something like... require 'sinatra/base' require 'net/http' t = Thread.new do class App < Sinatra::Base get '/' do 'Hi!' end end App.run! :host => 'localhost', :port => 1234 end sleep 2 puts Net::HTTP.start('localhost', 1234) { |http| http.get('/') }.body t.join puts 'Bye!' ...but it doesn't feel optimal to sleep for two seconds, waiting for Thin

由 和自甴很熟 提交于 2019-11-30 19:58:31

For example /events returns a HTML page and /api/v1/events returns a JSON data. According to some best practices , I want to split those into two different applications. I have chosen Sinatra to implement the API application. It works now for simple requests where authentication is not required. My Ruby on Rails 3 application is using Devise to authenticate users. There's also ability to login with

Could someone give me an example of node.js application

由 心已入冬 提交于 2019-11-30 14:00:51
I'm trying to understand the differences between some of the newer web programming frameworks that now exists, namely Node.js, Rails, and Sinatra. Could someone give me an example of applications that would work best on each of the frameworks? That is to say, what is an application that would be best suited for Node.js as opposed to Rails or Sinatra and what is an application that is best suited for Rails as opposed to Node.js and Sinatra etc..... Sinatra and Rails are both web frameworks. They provide common web development abstractions, such as routing, templating, file serving, etc. node.js
