In order to do recursive copying of the files we'll use a library called ncp.

If you need some inspiration, you can check out my files at /dkundel/create-project. Our code will later simply copy those files into the new project. Inside that directory place any package.json that you would like to use as the base of your project and any kind of files you want to have copied into your project. This post will use these names but feel free to use other names you'd like.

Those are the lower-cased versions of the two values that we prompted the user to pick from. We'll allow the target directory to be also modified via the options in case you want to re-use the same logic inside another project.īefore we write the actual logic, create a templates directory in the root of our project and place two directories with the names typescript and javascript into it. Our CLI will write into an existing directory similar to npm init and it will copy all files from a templates directory in our project. Now that we are able to determine the respective options through prompts and command-line arguments, let's write the actual logic that will create our projects. Instead you'll immediately see the determined options output. Try to run the same command with -y and the prompts should be skipped. Take as an example create-flex-plugin, a CLI that you can use to bootstrap a plugin for Twilio Flex.

oclif a framework for building extensible CLIs by Heroku ( gluegun as an alternative)Īdditionally there are many convenient ways to consume CLIs published to npm from both yarn and npm.

One of the reasons why Node.js got so popular is the rich package ecosystem with over 900,000 packages in the npm registry. In this post we'll look at why you might want to write a CLI, how to use Node.js for it, some useful packages and how you can distribute your new CLI. And thanks to package managers like npm and yarn, these can be easily distributed and consumed across multiple platforms. Command-line interfaces (CLIs) built in Node.js allow you to automate repetitive tasks while leveraging the vast Node.js ecosystem.
