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 🙏

Readme

If-only

A tiny react component that only renders children if a condition if met.

Installation

Install it using yarn:

$ yarn add if-only

Usage

Simple usage

const Component = () => (
  <div>
    // ...
    <If cond={someCondition}>
      // will render if someCondition is true
    </If>
  </div>
);

Advanced usage

If there's only one child, then it's going to render that child, but if there's more than one child, then, it's going to wrap them with an external component. That external component depends on the following props.

Manually specifying the external component

This takes precedence over any other prop.

const Component = () => (
  <div>
    // ...
    <If cond={someCondition} component={MyExternalComponent}>
      // will render if someCondition is true wrapping it with <MyExternalComponent>
    </If>
  </div>
);

Using a default external component

If inline is specified, it will wrap the children with a span tag. Otherwise, it will just use a div tag.

const Component = () => (
  <div>
    // ...
    <If cond={someCondition} inline>
      // Will render if someCondition is true wrapping it with a <span>
      <div />
      <div />
    </If>
  </div>
);

Specifying style and className for external component

If a external component is to be rendered, the className and style props can be specified on the If component and it will pass them down to the external component.

const Component = () => (
  <div>
    // ...
    <If cond={someCondition} className="CustomName">
      // Will render if someCondition is true. External <div> will have className="CustomName"
    </If>
  </div>
);
