Installation

NodeJS

Browser

Import the script:

<script src="https://joker876.github.io/edit-history/edit-history.min.js">

And import the class from a global object:

new EditHistory(/* capacity */);

Usage

import EditHistory from 'edit-history';

Constructor

new EditHistory<T = any>(capacity: number);

EditHistory constructor takes the history's maximum capacity as its only argument. Capacity is optional, and defaults to 100.

The type of the elements can also be specified explicitly. The default type is any.

const history = new EditHistory(50);
// or with specified type
const history = new EditHistory<number>(50);

Members

• size - the amount of past changes in the history (changes that can be undone).
• undoAmount - alias of size.
• redoAmount - the amount of future changes in the history (changes that can be redone).
• capacity - the maximum number of elements that can be stored in the history. Exceeding this value will cause the elements to be overwritten when pushed.
