Custom File Generator CLI Tutorial
View custom-file-generator-cli-tutorial.md

As a developer who works on multiple React projects daily, I like having a tool that can help me quickly and efficiently write consistent code. One of the best ways I've found is writing a custom command line tool to rapidly scaffold out my most common code patterns.

My tool of choice is Plop.js. Plop is a powerful "micro-generator framework" built to help maintain patterns as well as speed up your project build time. From the documenation:

If you boil plop down to its core, it is basically glue code between inquirer prompts and handlebar templates.

In this tutorial, we'll build out a simple React component generator for your Typescript projects. By the end, you'll have a fully functioning CLI that is customized to your file generating needs. Let's get started.
