Usage

Here we cover how to properly use Content Watcher library. The ContentWatcher instance requires a function as first argument and optionally can receive a second argument used as custom inital content. The default content is null. Let's see some examples:

Callback

Set a callback and implement the class:

import ContentWatcher from 'content-watcher';

const updateCallback = (_v) => { console.log(_v) };
const contWat = new ContentWatcher(updateCallback);

console.log(contWat.content); // null
contWat.content = 'final content'; // console logs 'final content'

Custom Initial Content

It accepts a second argument used as custom initial value:

import ContentWatcher from 'content-watcher';

const updateCallback = (_v) => { console.log(_v) };
const contWat = new ContentWatcher(updateCallback,  'initial content');

console.log(contWat.content); // 'initial content'
contWat.content = 'final content'; // console logs 'final content'

Plan

Some features what are expected for future versions:

• support for custom handler for different content types;
• official TypeScript version; Feel free to suggest features for futures versions, just open an issue.
