How to generate a file with Node.js from a predefined template?

Question

I am building an app with React Native and when I need a new component, I go through a few steps (lets assume I need a Button component) :

1. Create a new folder: /src/components/Button
2. Create Button.js
3. Create Button.styles.js
4. Create index.js , which exports both the component and its styles

That's takes some time, so I want to create a script that does the following things:

1. Prompts a new component name
2. Checks if that component already exists. If so, displays error

3. Creates files listed above with predefined templates, for example:

    import $component from './$component'; import styles from './$component.styles'; export { $component, styles }; 

   where $component is a name, provided via cli.

I can create folder and files with node, but how can I write a template and provide a variable to those files?

Answer 1

Create a template file manually. While running your script, read the contents of the file and then replace predetermined variable ($component for example) with the name from the console.
