RIVER CLI

The river CLI tool provides a central service for creating, managing and configuring projects at RIVER.

Usage

Available Commands

• new: Create a new Laravel project using the default branch of the river-laravel-template repository
• version: Display the CLI version

Laravel

• env:init: Generate Laravel's .env file

Terraform

• terraform:init: Generate the terraform configuration
• terraform:apply: Apply the terraform configuration
• terraform:download: Download the AWS configuration file
• terraform:install: Run all terraform commands

Bitbucket Pipelines

• pipelines:init: Generate the bitbucket-pipelines.yml configuration
• pipelines:add: Add a new deployment to the bitbucket-pipelines.yml configuration
• pipelines:remove: Remove a deployment from the bitbucket-pipelines.yml configuration

Lando

• lando:init: Generate the .lando.yml configuration

Development

To develop on the CLI locally, follow these steps:

Install dependencies

npm install
npm install -g ts-node  # typescript version of `node`

*Note: Node 16 or later is required.*

Run Commands

# Invoke the CLI application
ts-node src/index.ts

# Show the help menu explicitly
ts-node src/index.ts --help

# Run a command
ts-node src/index.ts new

A note on performance

If you are using an IDE with Typescript support, you can skip the compile time type-checking and get native JS speeds when running commands. Simply pass the transpileOnly flag when running the command.

ts-node -T src/index.ts

Adding new Commands

Commands are automatically loaded from the src/commands directory. This is not recursive.

All commands must extend the Command class exported from src/command.ts

Working with the CLI during development

Create a new project locally, using example as the production domain (this is ignored via .gitignore)

ts-node src/index.ts new

Change into the project directory and call the CLI using relative paths, not the global install.

cd example
ts-node ../src/index.ts env:init

Deployment

To publish the package, ensure you are logged into the RIVER agency NPM account.

Steps

# Start from a clean working directory
git add .
git commit -m "your message"
git push

# Tag a new version
# 	major: Major release / Breaking changes (e.g. 2.0.0)
# 	minor: Feature release / Non breaking changes
# 	patch: Bug fix releasee / Non breaking changes
npm version minor


# Publish the package
npm publish

Note: The prepublishOnly and postpublish NPM scripts have been configured to automate the discrete build steps

Documentation

Command API

• name: The name of the command (required)
• description: An optional description for the command
• options: An object representing any flag that can be passed to the command. The key will be used as the flag and the value the description.

protected options = {
	'--force': "Force the command"

	// Optionally, define a shortcut
	'--force': ["-f", "Force the command"]
}

Flags can be accessed from the handle method (described below).

const isForced = this.flag("force", true /* optional default */);

• handle: The async function to run when the command is invoked.

public async handle() {
	return 0;
}

Note, if invoking the command from another command, returning a value will not exit the process. To exit manually, you can call the exit method.

public async handle() {
	//...

	this.exit(); // Same as this.exit(0);
}

Return values

• 0 (integer) = Exit without errors
• 1 (integer) = Exit with errors
• any other value = Exit without errors

Invoking commands programatically

You may call any registered command by "dispatching" it via the application container.

public async handle() {
	const result = this.app.dispatch("other-command")

	// You may also provide flags
	const result = this.app.dispatch("other-command", {
		'--force': true, 	// By flag
		'-f': true, 		// By flag shortcut,
		'force': true, 		// By flag name,
    })
}

Writing Console Output

public async handle()
{
	this.info("Hello world") 	 // Prints green tex
	this.warn("Hello world") 	 // Prints yellow textt
	this.error("Hello world") 	 // Prints red text
	this.line("Hello world") 	 // Prints gray text
	this.jsonLine("Hello world") // Prints formmated json (gray)
	this.newLine() 				 // Prints 1 new line
	this.newLine(3) 			 // Prints 3 new lines
	this.loading("Hello world")  // Display a loading spinner with a message
	this.loading(false)			 // Stop the last loading spinner
}

Accepting input

public async handle()
{
	// Accept text input
	const name = await this.ask("Question", "default value");

	// Accept true/false input
	const runInProd = await this.confirm("Run in production?", false);

	// Pick from a list of options
	const mode = await this.prompt(
		"Which mode to run?",
		["Long", "Short"],
		"Short"
	);
}
