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 🙏

Redux Swarmlog

travis build version

ScreenShot

A super simple way of writing distributed Redux applications. The Redux action log is persisted in an IndexDB and synced with other peers via a WebRTC Swarm using Swarmlog.

When an application reloads the Redux store is initialsed by reducing all the persisted actions in the IndexDB and syncing any new actions from remote peers. Watch the Egghead video above to find out more.

Pros

  • offline data by default
  • super simple mental model for writing distributed apps
  • UIs update automatically as remote actions come in
  • works offline by default
  • scales globally for free with no bandwidth or storage costs for the developer
  • the developer is not responsible for client data
  • friends not cooperations hold user data
  • public / private key authentication is lighter weight than user accounts
  • time travel

Cons

  • Action logs use more bandwidth than raw data so initial sync could be slow for a very long log.

workaround: Break down long logs into lots of smaller logs e.g. log per month, week or day. Only fetch the most recent log if its all thats needed

  • Extra storage space needed on client

workaround: The price of SSDs is falling very rapidly. Stop thinking about cloud and thin client, but cache encrypted data where it is needed. This gives privacy, enables working offline, provides backups and can act as a CDN. Once you start using a distributed system like Git you soon stop thinking about the extra space it requires.

  • Permanence: even if an action deletes an item it can still be retrieved from the log.

workaround: Use a log for versioning other logs. Every so often the main log is reduced and a single action is written to a new log which creates the store in the current state. The old log is marked as stale in the version log and its database is deleted (purging old actions).

  • Can't get most up to date data if the peer holding it is offline

workaround: A small device like a Raspberry PI kept online should be all that is needed to make sure there is always at least one up to date source of truth. With 5G and IoT we are heading towards an era of always online small connected devices. Let's start thinking that way now.

Play to Strengths

Redux Swarmlog works well for apps that support some kind of physical live event. Because you know the action log will be short and the users will be online at the same time. Examples might be providing subtitles via mobile phone for a theatre show or letting a teacher see in realtime how each individuals in a class is answering a question.
