Appium Architecture (Series)

How is Appium built?

Appium is basically an HTTP server written in Node.js® that creates and handles webdriver sessions.

Node.js® is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Appium architecture

As Appium is an HTTP server, its performs pretty much same as Selenium Webdriver server by

• Receiving request/commands from client libraries*
• Executes the command on the target devices/emulators
• Responds with an HTTP response

Hence Appium works as a Client/Server architecture.

Client libraries

Appium client libraries has different language bindings like

• Ruby
• Python
• Java
• JavaScript
• PHP
• C#
• RobotFramework
