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 🙏

Server Side React Render

Readme

kneejerk

Current Version Build Status via Travis CI Dependencies

belly-button-style

KneeJerk is a minimal utility for server side React rendering. KneeJerk is server framework agnostic. You simply pass in a react-router configuration and URL, and KneeJerk renders the HTML using react-router. You can optionally pass in a root component to wrap the router output in order to achieve full page rendering.

const KneeJerk = require('kneejerk');

KneeJerk({
  root: require('your-html-wrapper.jsx'),
  routes: require('your-routes-file.jsx'),
  location: '/dashboard'
}, (err, results) => {
  reply(results.markup);
});

Methods

KneeJerk exports a single function, described below.

kneeJerk(options, callback)

  • Arguments
    • options (object) - A configuration object supporting the following keys.
      • location (string) - The URL path to match in the react-router. Required.
      • routes (object) - The routes configuration passed to the react-router.
      • render (string) - The react-dom rendering function. This can be set to null to disable rendering. Defaults to 'renderToStaticMarkup'.
      • root (function) - A react component used to wrap the rendered output. This is used to create a complete server rendered page. This can be explicitly set to null to prevent adding a wrapper. Defaults to null.
      • rootDoctype (string) - A DOCTYPE to prepend to the root rendering. Defaults to '<!DOCTYPE html>'.
      • rootMarkupProp (string) - The property named used to pass rendered markup to the root component for wrapping. Defaults to 'markup'.
    • callback (function) - A callback function receiving the following arguments.
      • err (object) - A Boom error representing any problem that occurs. If no match is made by the router, this will contain a Boom 404 error. This will be null if no error occurs.
      • results (object) - An object containing the following keys.
        • redirectLocation (object) - An object containing information about a potential redirection. This comes directly from the react-router output.
        • renderProps (object) - An object containing the props you should pass to the routing context. This comes directly from the react-router output.
        • markup (string) - The rendered output of the matched route, or the root rendering if one was provided. If there is no rendered output for any reason, this will be null.
  • Returns
    • Nothing. See arguments passed to callback.
