README 文档

README

This is a frontent library designed and built for use in Iowa State University web projects.

Staging site: staging2.idfive.com, currently displaying the master branch. Use guest/guest for username/password.
Repo: Bitbucket private.
Build pipelines: Buddy, idfive access only.

Installation of this library into your projects

Installing via composer

Whenever possible, we reccomend using composer to install this library, to ensure all future updates can be pulled in to your project.

composer require iastate/frontend-component-library

Using the library

In general, to use this library in your own project, you would need to link the CSS/JS files from the build folder:

Link to /build/css/index.css
Link to /build/css/print.css (print syles only)
Link to /build/js/index.js

You can then pull, and utilize the provided markup examples in your own project.

Development

This library is designed to be used "as-is" for most developers. If you wish to modify this library, you will need to create your own fork. This section is strictly information for those working on, and committing to, this project.

The component library includes Fractal for component based development. Your own components can be added to the src/components folder. Static assets such as JavaScript, CSS and images will be served out of the build folder, but can also be configured to your specific needs by editing the fractal.js file. For more information, read the fractal guide.

General notes:

Installed Boostrap 5.1, the site uses the default breakpoints
Using Iowa State color variables
Using Iowa State Font Awesome for social media icons and various elements
All CSS/JS is scoped to not interfere with Boostrap, using a prefix of "iastate22-" on relevant classes
All components live in the src/components directory
The page structure can be found in src/components/_page-preview.twig. For individual components, the structure is located in src/components/_preview.twig

Dependencies

Dependencies need to be installed with node/npm, and is best pinned to stable versions via nvm. More on node usage at idfive.

cd idfive-component-library
nvm use
npm install

Building for development

To start the fractal development server:

cd idfive-component-library
nvm use
npm run fractal

Building for production

To build your code for production, prior to a release, run the following:

npm run build
npm run fractal:build

This will generate build and fractal folders at the root of your project. The build folder contains all of your compiled assets (CSS, JavaScript etc.), while the fractal folder contains a static generated version of your Fractal component library, which can be used for previews and an online reference to your component library. The build folder is committed, in order that projects may use it as a dependency directly.

Versioning

Releases for this project should follow Semantic Versioning.

Steps when releasing:

Commit (or merge) and push master to origin.
Tag 1.0.1 (the new release version), and push to origin. The tag is what composer uses to define a new release.

Markup

Written using Twig templates
Proper ARIA functionality is used to meet WCAG accessibility guidelines

Page wrapper and overall structure

This structure below shows the overall wrappers and ordering needed to properly display the layout:

<body>
  <a class="skip-link" href="#main-content">Skip To Main Content</a>
  <div class="off-canvas">
    <div class="max-bound">
      {% include "@site-header" with header %}
      <main id="main-content">
        {{ yield }}
      </main>
      {% include "@site-footer" with footer %}
    </div>
  </div>
  <!-- Scripts Here -->
</body>

The .skip-link link is provided for accessibility purposes
The .off-canvas div is in use to set overflow-x: hidden; on the whole page to prevent unwanted horizontal scrolling
Next is the .max-bound div, which provides a max-width, (and 100% width), centers the content and provides a background-color the the whole document
Next our main site header is added {% include "@site-header" with header %}
Then the <main id="main-content"> is added which contains all of the page content {{ yield }}
After the closing <main> tag, the footer is added {% include "@site-footer" with footer %}
Kitchen sink pages have an additional tag <div class="outer-pad"> directly after <main>, which provides left and right padding for the page

Images

All images should be added to src/images which compiles to build/images/*.

CSS/JS

All CSS/JS/Images will be compiled from src/*.
All CSS to be written as SCSS, and compiled via Webpack.
All CSS compiled from src/scss/index.scss
All theme JS is written as TypeScript, and compiled to stable, browser-compliant JS via Webpack.
ALL JS to be compiled from Typescript in src/js/index.ts

Utility Classes

In _base.scss, .align-left, .align-right, and .align-center handle images placed in WYSIWYG sections
In _base.scss, the .skip-link class is for the "Skip To Main Content" button for accessibility
In _placeholder-selectors.scss, .visible-for-screen-readers is used to hide content but allow it to be accessibly read/spoken
In _placeholder-selectors.scss, .outer-pad-x handles horiztonal padding throughout various parts of the site
In _placeholder-selectors.scss, %responsive-img is a placeholder selector which sets up object-fit for images and the padding-top percentage for the associated pseudo element which sets the height of the image
In _placeholder-selectors.scss, .caption is a re-used type style for image and video captions
In _placeholder-selectors.scss, .arrow is the arrow shape used throughout various button and nav styles
In _base.scss, there are two helper classes for remove the space above and below paragraph widgets. .paragraph-widget-no-margin-bottom will reduce the margin-bottom of the widget to zero and .paragraph-widget-no-margin-top will reduce the margin-top top zero. These both have !important tags attached to ensure there are no conflicts.

Acceptance Standards

W3C Validation
Passes Accessibility check using WAVE and Google Lighthouse
Provides fallback of full content for non-JS users.
