Custom File Generator CLI Tutorial

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.

    return new Promise((resolve, reject) => {
        fs.readFile(filePath, 'utf8', (err: any, data: string) => {
            if (err) reject(err)
            resolve(data)
        })
    })
}

const write = (filePath: string, fileName: string, fileExtension: string, content: any) => {
