Stub TypeScript definitions entry for commander, which provides its own types definitions
@types/commander provides TypeScript type definitions for the Commander.js library, which is a popular tool for building command-line interfaces (CLI) in Node.js applications.
Command Definition
Defines a command named 'start' with a description and an action to be executed when the command is called.
const { Command } = require('commander');
const program = new Command();
program
.command('start')
.description('Start the application')
.action(() => {
console.log('Application started');
});
program.parse(process.argv);
Option Parsing
Defines options for the command-line interface, including a boolean flag and a parameter with a default value.
const { Command } = require('commander');
const program = new Command();
program
.option('-d, --debug', 'output extra debugging')
.option('-p, --port <number>', 'port number', 3000);
program.parse(process.argv);
if (program.debug) console.log('Debugging enabled');
console.log(`Port: ${program.port}`);
Subcommands
Defines subcommands under a main command, allowing for more complex command structures.
const { Command } = require('commander');
const program = new Command();
const service = new Command('service');
service
.command('start')
.description('Start the service')
.action(() => {
console.log('Service started');
});
service
.command('stop')
.description('Stop the service')
.action(() => {
console.log('Service stopped');
});
program.addCommand(service);
program.parse(process.argv);
Yargs is another library for building command-line interfaces. It provides a similar feature set to Commander.js, including command and option parsing, but also includes additional features like generating help documentation and handling complex command hierarchies.
Oclif is a framework for building command-line tools, developed by Heroku. It offers a more structured approach to building CLIs, with built-in support for plugins, testing, and documentation generation. It is more opinionated compared to Commander.js.
Meow is a minimalistic library for building command-line interfaces. It focuses on simplicity and ease of use, making it a good choice for smaller projects or scripts. It provides basic command and option parsing, but lacks some of the advanced features found in Commander.js.
This is a stub types definition for commander (https://github.com/tj/commander.js). commander provides its own type definitions, so you don't need @types/commander installed!
