You may have heard of Platform Phoenix, but you don’t know how to get started. Platform Phoenix is a real-time system built on Erlang, and has a lot of advantages over Elixir. Here are some tips to get you started. In the first place, you should know that Phoenix uses WebSockets and Channels, which are both real-time programming systems. This can help you make the transition to Phoenix easier.
Elixir is a functional programming language
The Phoenix framework for Elixir has many benefits, including low latency and fault tolerance, preemptive scheduling, and multiple concurrent nodes. Elixir also provides a high level of readability and facilitates easy understanding of the concepts. It has been widely adopted in other cloud-based platforms, including AWS and Google Cloud. If you’re thinking of using Elixir to develop Platform Phoenix applications, it’s worth looking into the language’s benefits.
Platform Phoenix uses Elixir as its web application framework. It features the server-side MVC pattern and is based on the BEAM virtual machine, which is aligned with Erlang’s foundation. Phoenix features the Ecto language for reading databases, LiveView for real-time updates, Components for server-side rendered HTML pages, Plug for controllers, and a robust permissions system.
Erlang is a real-time system
The Erlang programming language supports distributed systems. Each process has a mailbox, which stores messages sent to it by other processes. The receive primitive fetches the messages and processes them according to the patterns in the mailbox. The message may be any Erlang structure such as primitives, tuples, lists, or functions. The message may be synchronous or asynchronous. Erlang processes can be distributed across different computers or ambient network conditions.
A ‘working prototype’ is the first step in any Erlang project. Erlang provides excellent prototyping support. A working prototype consists of a subset of functionality that is tested end-to-end. For example, a working prototype of an IM server can include functions such as signing on and sending messages to a remote server. This enables debugging and improvements in the system.
Phoenix uses WebSockets
Developers may be concerned that WebSockets are not developer-friendly, but the Phoenix framework provides support for them. Instead of relying on a separate server, Phoenix uses developer-friendly abstractions over WebSockets, such as Channels. These abstractions allow developers to easily connect to the web service. However, some developers might want to use a lower-level implementation. To get started, you can check the documentation of the Phoenix framework and find out how to implement websockets.
When used with Phoenix, WebSockets support soft real-time communication across millions of connected clients. A client connects to the server using a transport such as WebSocket and then joins topics. These topics may be public chat or product updates. A public chat room might have a topic called public chat. Another example might be a topic for a specific product ID. In this way, multiple clients can subscribe to the same topic.
Channels
With the help of channels, Platform Phoenix developers can create applications that allow bi-directional communication. Phoenix channels allow you to build chat rooms, tracking software, or sensors for IoT projects. The concept of channels is simple: clients connect to a server through a transport such as WebSocket, subscribe to a topic, and then receive messages. Using Phoenix channels can be done with any JavaScript client or Objective-C, Swift, C#, or Java.
In the example above, the message is received by the Channel client, which then sends a message to the Channel server process. This message is then broadcast out to other connected clients. The messages are then forwarded to distant PubSub servers, which then deliver the message to all subscribed clients. Channels support any type of communication protocol, including HTTP and TCP. The main benefit of Channels is that they enable you to create applications that can scale well.
