Function merge

Merges properties from a new object into an existing object.

This utility function performs a shallow merge, copying all enumerable properties from the new object to the old object. It's used internally to merge user-provided options with default configurations.

Example

const defaults = { color: 'blue', size: 40, opacity: 0.8 };
const userOptions = { color: 'red', size: 60 };

const merged = merge(defaults, userOptions);
// Result: { color: 'red', size: 60, opacity: 0.8 }
Copy

Example: Type-safe usage

import { SetCaptchaOptions } from './constants';

const defaultOptions: SetCaptchaOptions = { size: 40, color: 'blue' };
const userOptions: Partial<SetCaptchaOptions> = { size: 60 };

const result = merge(defaultOptions, userOptions) as SetCaptchaOptions;
Copy
