Ensure nested objects are always dereferenced

This version ensures nested objects are always dereferenced, even when a merge operation will not affect internal values.

Use named export instead of default

Changes

This version moves from using a default export for the merge function, to exporting it as a named function. This is to avoid some issues that some native ESM TypeScript projects were facing where it couldn't resolve the types correctly.

Update dependencies

This version just updates the dev dependencies of the project.

Add `allowUndefinedOverrides` option + update dependencies

Changes

This version includes a new option - allowUndefinedOverrides. If you provide it with false it will prevent explicitly-provided properties with a value of undefined from overwriting existing values:

import merge from "ts-deepmerge";

const objA = { value: 1 };
const objB = { value: 2 };
const objC = { value: undefined };

merge.withOptions({ allowUndefinedOverrides: false }, objA, objB, objC);

The result of the above example would be:

{ value: 2 }

Thanks to @norahmaria for raising an issue (#28) asking for this feature🙏

Add `uniqueArrayItems` option + update dependencies

Changes

This version includes a new option - uniqueArrayItems. If you provide it with false it will allow duplicate array items:

import merge from "ts-deepmerge";

const objA = { array: ["a", "b"] };
const objB = { array: ["b", "c"] };

merge.withOptions({ uniqueArrayItems: false }, objA, objB);

The result of the above example would be:

{ array: ["a", "b", "b", "c"] }
