Usage

String Enums

import Enum from "enum-xyz";

const { Summer, Autumn, Winter, Spring } = Enum.String();

console.log(Summer); // Outputs: "Summer"

Options for String Enums:

• casing: Transforms the string based on the specified casing style. Available options are snakeCase, camelCase, PascalCase, kebabCase, lowercase, and uppercase.
• transform: Provide a custom function to transform the enum values. This function takes the original value and returns a transformed value.

Example:

const { userId, userAddress } = Enum.String({ casing: 'kebabCase' });
console.log(userId); // Outputs: "user-id"

const options = {
  casing: 'kebabCase',
  transform: (value) => `https://api.example.com/${value}`
};
const { userEndpoint, orderEndpoint } = Enum.String(options);
console.log(userEndpoint); // Outputs: "https://api.example.com/user-endpoint"

Numeric Enums

Starts from 0 by default:

import Enum from "enum-xyz";

const { A, B, C, D } = Enum.Numeric();

console.log(A); // Outputs: 0

Options for Numeric Enums:

• startIndex: Start the numeric enum from a specific index.
• step: Increment the numeric values by a specific step (e.g., 2, 5, 10).

Example:

const { A, B, C } = Enum.Numeric({ startIndex: 5, step: 2 });
console.log(A); // Outputs: 5
console.log(B); // Outputs: 7

Symbol Enums

import Enum from "enum-xyz";

const { blue, red } = Enum.Symbol();

console.log(blue); // Outputs: Symbol(blue)

Options for Symbol Enums:

• global: Create a global symbol using Symbol.for().

Example:

const { blueGlobal } = Enum.Symbol({ global: true });
console.log(blueGlobal); // Outputs: Symbol.for('blueGlobal')
