Newton

Standing on the shoulders of giants

Abstract
The rwt-newton DOM component displays document references using standardized styling.

In the wild

To see an example of this component in use, visit the Compleat Botanica website. This component typically has no visible UI. To understand what's going on under the hood, use the browser's inspector to view the HTML source code and network activity, and follow along as you read this documentation.

Installation

Prerequisites

The rwt-newton DOM component works in any browser that supports modern W3C standards. Templates are written using BLUEPHRASE notation, which can be compiled into HTML using the free Read Write View desktop app. It has no other prerequisites. Distribution and installation are done with either NPM or via Github.

Download

Download using NPM

OPTION 1: Familiar with Node.js and the package.json file?
Great. Install the component with this command:

npm install rwt-newton

OPTION 2: No prior experience using NPM?
Just follow these general steps:

Install Node.js/NPM on your development computer.
Create a package.json file in the root of your web project using the command:

npm init

Download and install the DOM component using the command:

npm install rwt-newton

Important note: This DOM component uses Node.js and NPM and package.json as a convenient distribution and installation mechanism. The DOM component itself does not need them.

Download using Github

If you prefer using Github directly, simply follow these steps:

Create a node_modules directory in the root of your web project.
Clone the rwt-newton DOM component into it using the command:

git clone https://github.com/readwritetools/rwt-newton.git

Using the DOM component

After installation, you need to add two things to your HTML page to make use of it.

Add a script tag to load the component's rwt-newton.js file:

<script src='/node_modules/rwt-newton/rwt-newton.js' type=module></script>

Add the component tag somewhere on the page, supplying four pieces of slotted text:

span slot=h2 The h2 heading text (optional).
span slot=h3 The h3 heading text (optional).
span slot=dt A definition term.
span slot=dd A definition description. This typically has an anchor tag with the external reference.

Here's an example:

<rwt-newton role=navigation>
    <span slot=h2>Giants</span>
    <span slot=h3>Isaac Newton</span>
    <span slot=dt>Famous quotes</span>
    <span slot=dd><a href='https://example.com/shoulders-of-giants.html'> If I Have Seen Further</a> Using the understanding gained by major thinkers who have gone before in order to make intellectual progress.</span>
</rwt-newton>

Customization

The reference area has limited customization. Only the background color may be customized. Supply a background color using the background attribute.

<rwt-newton role=navigation background='#777'>
    ...
</rwt-newton>

Life-cycle events

The component issues life-cycle events.

component-loaded: Sent when the component is fully loaded and ready to be used. As a convenience you can use the waitOnLoading() method which returns a promise that resolves when the component-loaded event is received. Call this asynchronously with await.
