helper for watching ops log in mongoDB for changes in a collection or all changes

Usage

Typescript

// Typescript
import Watcher from 'opswatcher';
// node JS
const Watcher = require('opswatcher').default;
const uri = 'mongodb+srv://username:password@host/database';
const watcher = new Watcher(uri);
watcher.connect().then(() => {
    // get an event emitter for test collection
    const test = watcher.addWatcher('test');
    test.on('data', (doc) => {
        console.log('test watcher', doc);

watcher.global.on('data | error | close | end');
