Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Introduction

The TimeSeriesStatisticsManager is a TypeScript library designed to manage time series statistics using AWS DynamoDB. It provides an easy-to-use interface for adding and retrieving statistics, with built-in support for multiple time partitions, such as minutes, hours, days, months, and years.

Installation

Install the library using npm:

npm install dynamodb-time-series-manager

Usage

First, import the TimeSeriesStatisticsManager class and create a new instance with your desired options:

import { TimeSeriesStatisticsManager } from 'time-series-statistics-manager';

// Create a new instance of the TimeSeriesStatisticsManager:

const manager = new TimeSeriesStatisticsManager({});

// Add a statistic:

await manager.addStatistic("example_topic", Date.now());

// Get statistics:

const stats = await manager.getStatistics("example_topic", startTime, endTime);

Components of the TimeSeriesStatisticsManager

  1. TimeSeriesStatisticsManagerOptions: An object that you can use to configure the TimeSeriesStatisticsManager. It includes the following optional properties: table, client, and timePartitions.
  2. Statistic: An object representing a single statistic, which includes topic, period, count, and time_partition properties.
  3. TimePartition: An object that represents a time partition, which includes name, format, and interval properties.

Example

Here's a simple example demonstrating how to use the TimeSeriesStatisticsManager:

import { TimeSeriesStatisticsManager } from 'time-series-statistics-manager';

const manager = new TimeSeriesStatisticsManager({});

(async () => {
    await manager.addStatistic("example_topic", Date.now());
    
    const startTime = Date.now() - (60 * 60 * 1000); // 1 hour ago
    const endTime = Date.now();
    
    const stats = await manager.getStatistics("example_topic", startTime, endTime);
    
    console.log(stats);
})();

Conclusion

The TimeSeriesStatisticsManager provides a simple and efficient way to manage time series statistics using AWS DynamoDB. With built-in support for multiple time partitions, it makes it easy to add and retrieve statistics for various time ranges. Give it a try and see how it can help you manage your time series data.
