@sealsystems/counter-storage

@sealsystems/counter-storage manages handling of counters persisted in a MongoDB.

Installation

$ npm install @sealsystems/counter-storage

Quick start

First you need to add a reference to @sealsystems/counter-storage within your application:

const counterStorage = require('@sealsystems/counter-storage');

Then you can connect to a MongoDB. For that call the connect function and provide the database's connection string using the url property:

const storage = await counterStorage.connect({
  url: 'mongodb://localhost:27017'
});

Optionally, you may also specify the number of connection retries:

const storage = await counterStorage.connect({
  url: 'mongodb://localhost:27017',
  connectionRetries: 10
});

Get next counter value

To get the next counter value call the getCounter function and provide its name. Optionally you can provide the increment as second argument, default increment is 1:

const newCounterValue = await storage.getCounter('hugo');

With increment:

const newCounterValue = await storage.getCounter('hugo', 100);
