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.

const encodeGetParams = p => 
  Object.entries(p).map(kv => kv.map(encodeURIComponent).join("=")).join("&");

const params = {
  user: "María Rodríguez",
  awesome: true,
  awesomeness: 64,
  "ZOMG+&=*(": "*^%*GMOZ"
};

const password2 = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?!.*\s).*$/; // Password (UpperCase, LowerCase, Number/SpecialChar and min 8 Chars)

// Building-blocks to use for composition
const double = x => x + x;
const triple = x => 3 * x;
const quadruple = x => 4 * x;

// Function composition enabling pipe functionality
const pipe = (...fns) => input => [...fns].reduce((acc, fn) => fn(acc), input);

// Composed functions for multiplication of specific values
const multiply6 = pipe(double, triple);
