Percentage read, reading time & pointsby Read Write Tools
|The rwt-reading-points web component provides site visitors with a clue about a document's reading-level, using a descriptive learning level and experience points system.|
When user's browse technical documentation it's not always easy to know if a page is meant for first timers or advanced users. This web component provides that information using an ephemeral notification-style text block.
As the user reads, a timer tracks how many seconds is spent reading. As the user scrolls down, the readers progress (as percent read) is tracked. This information is saved to the user's local storage for use with the rwt-reading-summary web component.
The rwt-reading-points web 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.
Installation using NPM
If you are familiar with Node.js and the
package.json file, you'll be comfortable installing the component just using this command:
npm install rwt-reading-points
If you are a front-end Web developer with no prior experience with NPM, follow these general steps:
- Install Node.js/NPM on your development computer.
- Create a
package.jsonfile in the root of your web project using the command:
npm install rwt-reading-points
Important note: This web component uses Node.js and NPM and
package.json as a convenient distribution and installation mechanism. The web component itself does not need them.
Installation using Github
If you are more comfortable using Github for installation, follow these steps:
- Create a directory
node_modulesin the root of your web project.
- Clone the rwt-reading-points web component into it using the command:
git clone https://github.com/readwritetools/rwt-reading-points.git

- Provide a descriptive word to catagorize the document, using the
<rwt-reading-points id=reading-points data-time='190' data-points='4' data-level='Moderate' data-category='Phrasing'></rwt-reading-points>
Initially the component is hidden. It appears soon after the page first loads. It fades away after a few seconds.
The position of the text block is always immediately after the document element with the identifier
objectives. You should style your page to provide a small amount of whitespace in that area using
margin-bottom or something similar. The component itself is designed so that it does not occupy space.
The user's reading time is tracked by movement of the scroll bar placed on the document's outermost frame, which should be identified as
If the page does not have either the
objectives element or the
frame element, the component will be disabled. This is intentional, as it allows a generic template to be used for a website.

data-points attribute is zero, the component will also be disabled.
