In the previous article, I wrote about isFolderEmpty function that is used to prevent providing conflicting names for your project.

In this article, I will try to understand the following code snippet.

// Remember the example option? // if there is no example provided as part of your CLI command // that is where you see prompts for your project configuration const example = typeof program.example === 'string' && program.example.trim() // What is conf.get? in the one of previous articles, I wrote about Conf // package for setting preferences stored specific to your device const preferences = (conf.get('preferences') || {}) as Record< string, boolean | string > /** * If the user does not provide the necessary flags, prompt them for whether * to use TS or JS. */ if (!example) { // default preferences variable const defaults: typeof preferences = { typescript: true, eslint: true, tailwind: true, app: true, srcDir: false, importAlias: '@/*', customizeImportAlias: false, } // Interesting variable name // getPrefOrDefault // What if you write getConfPreferenceOrDefault? long one // Should prefer to abbreviate where possible, but not overdo it where it // meaning changes const getPrefOrDefault = (field: string) => preferences[field] ?? defaults[field] 

I have provided the corresponding comments in the above code snippet.

Conclusion:

This code snippet uses Conf preferences. If you have a package that takes user input via prompts in the CLI, I recommend this conf package to store user preferences local to their device.
