    Project mention: Ruby on Rails load testing habits | | 2024-01-25

    This is a great blog post! just taking the opportunity here to comment on this:

    > Finally for full scale high fidelity load tests there are relatively few tools out there for browser based load testing.

    It exists as of a few months ago and it's fully open source: (I'm the lead dev). You write a Playwright script, then run it in your own AWS account on serverless Fargate and scale it out horizontally as you see fit. Artillery takes care of spinning up and down all of the infra. It will also automatically grab and report Core Web Vitals for you from all those browser sessions, and we just released support for tracing so you can dig into the details of each session if you want to (OpenTelemetry based so works with most vendors- Datadago APM, New Relic etc)

    The third one is JSON-LD. I actually question the usefulness of this feature, but if it is relatively easy to implement without a glaring downside, just give it a shot I guess? In Next.js, there is next-seo package that greatly simplifies the implementation of JSON-LD.
