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.


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 🙏

Manage document head data with react-helmet. Provides drop-in server rendering support for Gatsby.





Provides drop-in support for server rendering data added with React Helmet.

React Helmet is a component which lets you control your document head using their React component.

With this plugin, attributes you add in their component, e.g. title, meta attributes, etc. will get added to the static HTML pages Gatsby builds.

This is important not just for site viewers, but also for SEO -- title and description metadata stored in the document head is a key component used by Google in determining placement in search results.


npm install --save gatsby-plugin-react-helmet react-helmet

How to use

Just add the plugin to the plugins array in your gatsby-config.js

plugins: [`gatsby-plugin-react-helmet`]

Titles don't appear when opening in the background, while using gatsby-plugin-offline

If you're using gatsby-plugin-offline, you might notice that when opening a link in the background, the title doesn't appear in the tab bar until switching to that tab. This is an upstream issue with React Helmet; however, it can be worked around by passing the defer={false} prop into your Helmet component. For example:

<Helmet title="foo bar" defer={false} />

Compatibility with React 16.8 useEffect hook

If you are using this plugin with React hooks, you may notice some errors like maximum call stack size exceeded. To ensure everything is running smoothly when using these technologies together, make sure to validate the following:

  • You have updated to the latest version of gatsby-plugin-react-helmet
  • You are using version 6.0.0-beta or later of react-helmet
  • You are importing React Helmet using import { Helmet } from 'react-helmet' rather than the old import Helmet from 'react-helmet'
