null-as-undefined

Convert null values to undefined in a way that TypeScript understands.

Installation

Install in the usual way:

npm install null-as-undefined

or

yarn add null-as-undefined

depending on your package manager of choice.

Usage

This package exports two functions and two types:

• nullAsUndefined<T>(value: T): NullAsUndefined<T>
• nullValuesAsUndefined<T>(obj: T): NullValuesAsUndefined<T>
• NullAsUndefined<T>
• NullValuesAsUndefined<T>

nullAsUndefined<T>(value: T): NullAsUndefined<T>

Takes any value and returns undefined if the value was null. Otherwise it returns the original value.

nullValuesAsUndefined<T>(obj: T): NullValuesAsUndefined<T>

Takes any object and returns a new object, replacing all null values with undefined.

NullAsUndefined<T>

Casts null values to undefined.

NullValuesAsUndefined<T>

Casts all null values of an object to undefined.
