Ruby on Rails is a web application framework.
Rails could be the framework, Ruby is the language.
Designed by David Heinemeier Hansson in 2005, it’s become renowned in the Internet startup world for its adoption by a number of the leading “startups” of our time, including Stripe, Uber and Groupon.
You an overview of what to do if you want to learn to program in Ruby on Rails, this tutorial should give. I will not get into specifics you an idea as to the structure of an application because I just want to give. I propose, you should more fully understand how these applications work if you follow what.
All software applications work in the way that is same
Data is inputted
Information is processed
Data is outputted
Just how the info is inputted and prepared is dependent on the platform the application runs on. Just how it is outputted will depend on the job.
The huge difference with web applications is their logic runs on a server, with the information IO being passed through the Internet (specifically, the HTTP protocol).
The problem of internet apps is the fact that you’re looking for the capacity to accept inbound data, and return responses. This is certainly handled by a web server program (NGinx or Apache). I’ll explain this ina moment.
Computer Software Stack
Whenever you create a piece of computer software, you need to think about the “stack” on which it runs.
The “stack” is all of the computer software needed to run the job. In the wonderful world of desktop games, for instance, the “stack” may include the kind of DirectX or a specific visuals driver.
The main hold-back for would-be internet application designers is understanding how the “web” pc software stack works. Web works similarly to native applications, with the exception of one difference that is distinct stateless.
The “Internet” runs under the HTTP protocol. Of course, this is referred to as a “stateless” protocol – each request you deliver is recognized as separate to your last. Each time unlike stateful protocols (which retain state), stateless protocols have to rebuild the application’s state.
Whilst this means nothing to most people, the overriding point is that in the event that you’re going to develop a web based application, you should employ a framework or technology set which makes the stateless nature of HTTP as incorporated possible. Most pertinently, you need an authentication system which rebuilds the consumer’s session on every demand (I’ll explain this in a second).
Ruby vs PHP
Ruby (the language) is akin to PHP – they are both procedural and both are used greatly on the web.
The difference that is main Ruby and PHP is that PHP is accessed entirely on the client-side, Ruby requires a proxy.
Applications such as for example WordPress are built with PHP since it’s free, available supply and certainly will be operate on any LAMP (Linux Apache MySQL PHP) server (that will be essentially most of the hosting that is shared in presence).
The purpose with Ruby is that it is a LOT more temperamental than PHP – it takes running procedures to help it operate and will frequently don’t begin if any problems arise.
To begin with, you will need three things:
An IDE (Built-in Developing Environment)
A Ruby-Compatible Online Server (Heroku)
Ruby, Rails & GIT Installed In Your System
