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 🙏

Reporter and Reporting lifecycle guidance

@as-pect/core owns the Test suite model, Reporting lifecycle, Suite report factory, and legacy reporter adapter. Custom reporters should prefer the report event callbacks exposed by IReporter:

  • onReportGroupStart(event) and onReportGroupFinish(event) receive { group } facts.
  • onReportTestStart(event) and onReportTestFinish(event) receive { group, test } facts.
  • onReportFinish(event) receives { report } facts for the completed suite.

These Report events carry stable Suite report facts that are ready to render. New reporters should read from SuiteGroupReport, SuiteTestReport, and SuiteReport instead of walking TestContext or mutable Test node state.

The older onEnter(ctx, node), onExit(ctx, node), and onFinish(ctx) callbacks remain available for compatibility with existing reporters and subclasses. Treat them as legacy extension points for migration only. The Reporting lifecycle now keeps compatibility-only TestContext and TestNode facts behind the legacy reporter adapter as legacy report facts so they do not leak into report event payloads.

If a reporter needs to create report facts directly, use createGroupReport(node), createTestReport(group, test), or createSuiteReport(ctx) from @as-pect/core.

Snapshot key format

@as-pect/core records snapshots under the full Test node namespace plus the explicit snapshot name passed by AssemblyScript code. The Test tree recorder creates the namespace used by the Snapshot lifecycle. A key contains each describe/it segment and duplicate-safe indexes before the snapshot name, for example:

outer[0]!~duplicate[1]!~renders value[0]

This is a breaking change from the older test-name-only snapshot keys. The namespace-derived format makes duplicate test names and repeated snapshot names deterministic because each snapshot is tied to the exact Test node that created it. Existing snapshot files should be regenerated or migrated for the next major release.
