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 🙏

wix-ui-theme

If you wish to implement a new component with some specific theme, the best choice for you would be to take a core component from wix-ui-core, and to add your own theme to it.

This package provides a nice API for creating a themed component from a core component with important performance optimizations.

Why do we need themes

  • Prevent code duplication by having one core components code base.
  • Make it easy to style components to match the different designs.

Themed libraries

The themes we currently have at Wix (WIP):

Creating a new theme

A theme is simply an object that we need to pass to the core component as a prop. The core component has no style by definition, or at least only a basic one. Each component must have it's own theme object. It should have a specific structure (TBD).

buttons

Why do we need this package

Since the whole idea is to provide a theme prop to the core component, one might wonder what the hell is this package needed for.

Why not simply do the following:

import CoreButton from 'wix-ui-core/Button';

const theme = {
  color: 'green',
  backgroundColor: 'red',

  hover: {
    color: 'white',
    backgroundColor: 'black'
  }
};

export const ThemedButton = props =>
  <CoreButton theme={theme} {...props}>;

We won't get into too many implementation details, but what is going to happen in this case is that for each prop change there will be a lot of DOM interactions to keep the styles up to date.

ThemedComponent

In order to boost the performance issue we faced in the previous example, this package exposes the <ThemedComponent> component which wrapps the core component and generates the styles from the theme object.

import CoreButton from 'wix-ui-core/Button';
import {ThemedComponent} from 'wix-ui-theme';

const theme = {
  color: 'green',
  backgroundColor: 'red',

  hover: {
    color: 'white',
    backgroundColor: 'black'
  }
};

export const ThemedButton = ({theme, ...coreProps}) => (
  <ThemedComponent theme={theme}>
    <CoreButton {...coreProps}> 
  </ThemedComponent>
);

theme: Object or a function that returns an object.

coreProps: The props for the core component.

This will result in a new component which has it's own style. The styles will be generated from the custom theme you need to write.

Conditional Theme

The core component is implemented in wix-ui-core, and the styles will be generated from the custom theme you need to write.

The theme is an object, or a fucnction that gets some optional additional props as arguments, and returns an object with a very specific structure. Each component has it's own theme structure. For example:

const theme = ({height, skin}) => ({
  fontSize: height === 'small' ? '14px' : '20px',
  color: skin === 'normal' ? 'white' : 'blue',
  backgroundColor: skin === 'normal' ? 'blue' : 'white',
  
  hover: {		
    color: 'blue',		
    backgroundColor: 'green'		
  }
});

Note that we usually wouldn't want to pass those additional props to the core component, although it is possible. Those props are being used to generate the theme object which we will then pass to the Core component.

All of that is being taken care of by the ThemedComponent component which expects to get the core component as a children prop, a theme function / object prop, and some optional props which can be used by the theme function in order to generate the theme object.

Here is an example of how to implement a themed Button component properly:

import CoreButton from 'wix-ui-core/Button';
import {ThemedComponent} from 'wix-ui-theme';

const theme = ({height, skin}) => ({
  fontSize: height === 'small' ? '14px' : '20px',
  color: skin === 'normal' ? 'white' : 'blue',
  backgroundColor: skin === 'normal' ? 'blue' : 'white',
  
  hover: {		
    color: 'blue',		
    backgroundColor: 'green'		
  }
});

export const Button = ({height, skin, ...coreProps}) => (
  <ThemedComponent theme={theme} height={height} skin={skin}>
    <CoreButton {...coreProps}/>
  </ThemedComponent>
);
