Azion CLI is an open-source tool designed to facilitate local development and testing of edge functions, allowing developers to run applications locally using the azion dev command. This enhances software quality by enabling error prevention, improved debugging, performance optimization, security enhancements, and cost-effective development through early detection and resolution of potential issues. Azion CLI works by invoking the Azion Bundler, which manages the build and local development process, initializing a server that emulates the Azion Edge Runtime. The tool supports edge functions for both applications and firewalls, each structured differently based on their event types, such as fetch and firewall events, respectively. Developers can test edge functions in a controlled environment, using JavaScript templates, hot reloads, and real-time logging to ensure correct functionality before deployment. For edge firewall functions, specific testing conditions require the use of a --firewall flag to simulate and assess the behavior under firewall conditions. Overall, Azion CLI streamlines the development process, ensuring robust, secure, and efficient edge computing solutions.
