Dojo CLI Architecture

CLI Lifecycle

The dojo cli is composed of a modular set of commands that allows for customization and extension.

A CLI command is broken into four parts: the executable (dojo), a group name, a command name, and parameters

> dojo create app --name MyApp

Initialize Phase

Loads commands internally and from package.json

Register Phase

A group's commands are loaded in by name and a default command is registered.

This phase calls register() on the command as part of the yargs builder step.

Validate Phase

Run validation if it exists on the command. If validation fails then stop.

This phase calls validate() on the command. This is where schema validation occurs.

Run Phase

Runs the command.

This phase calls run() on the command.
