constant-case

What is constant-case?

The constant-case npm package is used to convert strings into constant case format, typically used for defining constants in programming. This format involves converting all letters to uppercase and replacing spaces and other special characters with underscores.

What are constant-case's main functionalities?

String Conversion to Constant Case

Converts a given string into constant case, making all characters uppercase and replacing spaces and special characters with underscores. Useful for creating identifiers in code that are typically constants.

const constantCase = require('constant-case');

console.log(constantCase('string to convert')); // 'STRING_TO_CONVERT'

Other packages similar to constant-case

change-case

A comprehensive toolkit for converting text between different cases. It includes constant-case as one of its many functions, along with other cases like camel case, capital case, and more. This makes change-case more versatile compared to constant-case, which specializes in only constant case conversion.

upper-case

Converts a string to uppercase. It is similar to constant-case in that it affects the letter casing, but it does not replace spaces or special characters with underscores, thus it's less suitable for creating constant identifiers but useful for general uppercasing needs.
