== Phoenix (web framework) == [[File:Phoenix logo.png|thumb|Phoenix Logo]] '''Phoenix''' is a [[web framework]] written in the [[Elixir (programming language)|Elixir]] programming language. It was created with the goal of providing developers with a productive and reliable tool for building scalable web applications. === Features === * '''Concurrency''': Phoenix leverages the power of Elixir's lightweight processes to handle a large number of concurrent connections efficiently. * '''Scalability''': With its built-in support for distributed and fault-tolerant systems, Phoenix allows developers to easily scale their applications as needed. * '''Productivity''': Phoenix aims to promote developer productivity by providing a pleasant, elegant, and productive programming experience. * '''Real-time''' functionality: Phoenix makes it easy to build real-time applications using WebSockets and channels. * '''Routing''': Phoenix provides a powerful routing system that enables developers to define clear and structured routes for their web applications. * '''Database integration''': Phoenix seamlessly integrates with Ecto, the database wrapper for Elixir, allowing developers to easily interact with databases. * '''Testing''': Phoenix includes a robust testing framework that assists developers in writing comprehensive and reliable tests for their applications. === Getting Started === To start using Phoenix, developers need to have Elixir installed. Then, they can install Phoenix by running the following command: ```shell $ mix archive.install hex phx_new ``` After installing Phoenix, developers can create a new Phoenix application with the following command: ```shell $ mix phx.new my_app ``` === Examples === Here are a few examples of how to use Phoenix: ==== Routing ==== Phoenix provides a routing system that allows developers to define the URL routes for their web application. Here is an example of how to define a simple route: ```elixir defmodule MyAppWeb.Router do use Phoenix.Router get "/", PageController, :index end ``` ==== Controllers ==== Controllers define the actions that can be performed in a Phoenix application. Here is an example of a controller action: ```elixir defmodule MyAppWeb.PageController do use MyAppWeb, :controller def index(conn, _params) do render(conn, "index.html") end end ``` ==== Views ==== Views in Phoenix are responsible for rendering templates and generating HTML responses. Here is an example of a view in Phoenix: ```elixir defmodule MyAppWeb.PageView do use MyAppWeb, :view def render("index.html", _assigns) do "<h1>Welcome to my website!</h1>" end end ``` === Conclusion === Phoenix provides a powerful and efficient web framework for building scalable and reliable applications using Elixir. With its focus on productivity and performance, Phoenix is a great choice for developers looking to create modern and robust web applications. == See Also == * [[Elixir (programming language)]] * [[Ecto (Elixir)]] == References == {{reflist}} [[Category:Web frameworks]] [[Category:Elixir (programming language)]] [[de:Phoenix (Framework)]] [[es:Phoenix (framework web)]] [[fr:Phoenix (framework web)]] [[ja:Phoenix (ウェブフレームワーク)]] [[pt:Phoenix (Framework)]] [[ru:Phoenix (фреймворк)]] [[tr:Phoenix (web çatıs]]
