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 🙏

📊 Prometheus integration for Nuxt 3

Allows you to better understand what's going on with your application and how to optimize performance and other things in production. Nuxt 2 users can use this version.

Limitations

Due to this issue in ofetch package @artmizu/nuxt-prometheus cannot detect network requests which take place through useFetch or $fetch, because they both use ofetch inside. So on the /metrics page, you don't see any request time related to ofetch. Future investigation will take place here.

Features

  • Default NodeJS metrics exported through the prometheus middleware
  • Custom metrics about pages render time and external request consumption time
  • Health check middleware

Default routes that you can customise via the module options

  • /metrics - prometheus metrics
  • /health - health check

Installation

Install package via a package manager:

# using nuxi, it automatically appends the module in your nuxt.config
npx nuxi@latest module add prometheus

# using npm
npm install @artmizu/nuxt-prometheus

# using yarn
yarn add @artmizu/nuxt-prometheus

# using pnpm
pnpm add @artmizu/nuxt-prometheus

Add it to a modules section of your nuxt config:

export default {
  modules: ['@artmizu/nuxt-prometheus']
}

Grafana sample setup

Once the metrics have been collected by Prometheus, you will want to review them. I use Grafana for this purpose, and my metrics setup looks something like this: Cover

Options

You can pass it through module options and the nuxt config property prometheus.
