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 🙏

Problem:

In our survey, most abstracted JavaScript communications libraries either target a specific platform (e.g. Node.js or jQuery) or a specific framework (e.g Vue.js). The purpose of this project is to create a simple and flexible set of JavaScript communication libraries for cross-platform and cross-framework use, specifically targeted at interacting with SPARQL endpoints: bbop-manager-sparql.

Significance

Without the creation of low-level common infrastructure, developers are left to recreate the wheel, wasting unnecessary bandwidth, and possibly creating incompatible solutions that may cause more issues down the road.

Approach

The JavaScript library set that we will base our work on is one already in use by applications such as AmiGO and various Noctua clients, both in browsers and on the server; the BBOP libraries ( bbop-rest-manager and berkeleybop/bbop-rest-response ) are a client/server safe abstraction that has many implementation engines for both sync and async communication, across jQuery (browser), Node.js, and Rhino. In order to support the use cases we have for these libraries (automatic GET/POST switching to help endpoint caching, SPARQL templating, etc.) we first needed make adjustments and improve these core libraries before moving on to library creation. These upstream changes, bugfixes, and test coverage ended up taking the bulk of the effort; however, with these new pieces in place, progress on bbop-manager-sparql proceeded quickly. The templating use case was easily covered, but raised questions about the best approach to take in this space, where there is no apparent leading standard.

Next steps

Moving forward, the library will develop along with the use cases of the userbase; resolving SPARQL template handling in a standard way is already under discussion, exploring both supporting a TBD standard or multiple contenders, including the custom one already in use in the library.
