@frontity/components

Description
This package is a collection of React components that have proven to be pretty useful for a Frontity project.
How to use
In order to use it, you just have to import the component you want to use in your theme from @frontity/components/ and place it wherever needed. For example, if we want to use the <Image />component:
import Image from "@frontity/components/image";
Components
Image
<Image /> is a React component that adds lazy-loading to the native WordPress images. Combined with @html2react/processors , you can add this functionality and optimize your images pretty easy.
Script
<Script /> is a React component that executes scripts tags found in content.
Props
Name
Type
Default
Optional
Description
src
string
null
true
URL to an external JavaScript  file.
code
string
null
true
internal JavaScript code
id
string
null
true
ID for script element
Usage
External JavaScript file:
import Script from "@frontity/components/script";
​
const MyComponent = () => (
    <Script src="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/js/bootstrap.min.js />
);
Internal JavaScript code
import Script from "@frontity/components/script";
​
const MyComponent = () => (
    <Script code={`
        const body = document.querySelector('body');
​
        // Triggers anytime anywhere in the body of the page is clicked
        body.addEventListener('click', e => {
            e.preventDefault();
            console.log('Button Works');
        });
    `} />
)
Iframe
<Iframe /> is a React component that implement lazy-load on iframe components. The approach taken in implementing this component is based off the edge cases in the table below.
Intersection Observer
Native Lazy
Height > 0
Output
true
true
true
Native Lazy Load
true
true
false
Intersection Observer

Native Lazy needs a height attribute. For that reason, we use the Intersection Observer when a height is not provided.

Usage
import Iframe from "@frontity/components/iframe";
​
const MyComponent = () => (
    <Iframe
        src="https://frontity.org"
        title="Frontity"
        height="500"
        width="500" 
    />
);
Switch
The <Switch /> renders the first child component that returns true as the value of its when prop.
The last child component (which should not have a when prop) will be rendered if no other component matches the condition.
You can use it for routing to different components in your theme:
import Switch from "@frontity/components/switch";
​
const Theme = ({ state }) => {
    const data = state.source.get(state.router.link);
​
    return (
        <Switch>
            <Loading when={data.isFetching} />
            <Home when={data.isHome} />
            <Archive when={data.isArchive} />
            <Post when={data.isPostType} />
            <ErrorPage /> {/* rendered by default */}
        </Switch>
    );
}
But also inside any other component. For example, in a <Header> component that has a different menu for the home:
import Switch from "@frontity/components/switch";
​
const Header = ({ state }) => {
    const data = state.source.get(state.router.link);
​
    return (
        <Switch>
            <MenuHome when={data.isHome} />
            <Menu /> // rendered by default
        </Switch>
    );
}
This component is an alternative to applying plain JavaScript logic in React:
const Theme = ({ state }) => {
    const data = state.source.get(state.router.link);
​
    return (
        <>
          {(data.isFetching && <Loading />) ||
           (data.isHome && <Home />) ||
           (data.isArchive && <Archive />) ||
           (data.isPostType && <Post />) ||
           <ErrorPage />}
        </>    
    );
}
