UNL WDN Templates

The template files are developed and maintained by the Web Developer Network (WDN) at the University of Nebraska-Lincoln. These templates are made up of HTML, CSS and JavaScript to power the underlying web presence.

Template Usage

Template usage is subject to the WDN Terms of Use.

Templates Available

All templates variations utilize the same HTML markup, with an exception of the body class, ex: class="document".

Collaboration

All members of the WDN are invited to contribute to this project. Please make a fork of the main repository for local development. Once you have created and tested your code, please send a pull request to the main repository.

Building Template Resources

Much of the template CSS and JavaScript is built using aggregators, preprocessors, and/or "minifiers". You can build a local copy of these resources with the following instructions as your guide.

The resources are built using a Gruntfile. The following tools are required to be installed.

• Git -- version control system
• NodeJS -- used to run the libraries that process and minimize LESS and JavaScript files
• Grunt -- The Grunt CLI must be installed ( npm install -g grunt-cli ) in order to build.

Installing the additional resources necessary to build the system can be downloaded by running npm install from the project root.

Once all of the above dependencies are met, simply running Grunt grunt at the project root will build all resources. The following are all of the supported targets.

• default or all - builds all needed CSS and JavaScript
• clean - removes all built files
• js-main - builds and minifies combined JavaScript
• css-main - builds all CSS files from their SCSS partials and passed through postcss
• dist - builds the ZIP's used for template distribution. Also does smudging of keywords such as $DEP_VERSION$ in dwt and include files

The JavaScript build process can be further customized by passing parameters. The following are the flags that are supported.

EXAMPLE: Build for use in a special CDN or server location grunt --rjs-flags="wdnTemplatePath=//www.unl.edu/"

EXAMPLE: Customize the UNLchat url. Could be useful for integrating a custom instance of UNLchat or for development grunt --rjs-flags="unlChatURl=//ucommchat-test.unl.edu/assests/js"

EXAMPLE: Build for use in debug mode for analytics grunt --rjs-flags="debug_mode=true"

EXAMPLE: Customize the Analytics Measurement ID grunt --rjs-flags="wdnProp=G-9DM5F2WV3Y"

EXAMPLE: Two or more parameters are separated with a space grunt --rjs-flags="wdnTemplatePath=//www.unl.edu/ unlChatURl=//ucommchat-test.unl.edu/assests/js"

PLEASE NOTE: The build process has been optimized for a Linux or OS X environment. While it is technically possible to build on Windows, the specifics of setting up your environment correctly are beyond the scope of this project.

Further support

Support of the UNL Templates is coordinated and communicated through the WDN.

5.3 Development Documentation for Developers

Folder Structure

Directories

templates_5.3/js-src/

• contains JavaScript source files.
• All files in this folder will be first copied to the templates_5.3/js folder (through the Grunt sync:js task) before require.js works on them
• *.babel.js files will be transpiled and outputted to /js/*.js

templates_5.3/js-src/plugins/

• Place vendor libraries here

templates_5.3/js-src/utility-scripts/

• Place script files here that are not require.js modules or widgets but are standalone files for transpile and minification purposes

templates_5.3/js/

• Contain files and folders to be worked and bundled by require.js. Files from DCF are also pulled into this folder when the Grunt task js-main is ran

templates_5.3/js/compressed/

• Production-ready JS files, containing the require.js entry file all.js

templates_5.3/scss/*

• place theme SASS partials in this folder.
• main SASS files include glob patterns that will pull in DCF SASS partials for compilation
• tmp.scss files can be used to import styles into other projects. The most likely use case will be to use pre.tmp.scss to import framework variables, mixins and functions.

scripts/

• contains bash scripts for deployment and distribution

Files

.gitattributes

• path to files that contain keywords such as $id$ and $DEP_VERSION$ that needs to be replaced with git commit information by the filter-clean and filter-smudge Grunt tasks.
• Paths in this file must match the filterFiles variable inside of Gruntfile.js

.git_filters/lib/git-filters.js

• contain git filter clean and smudging methods that is imported into Gruntfile.js as gitFilters variable. Methods are used in the filter-clean and filter-smudge Grunt tasks.

Critical CSS

The script to remove inline critical styles once the core stylesheets have been loaded can be found in js-src/utility-scripts/clearCriticalCSS.js. If changes needs to be made to the script, grab the minified and transpiled version from js/compressed/utility-scripts and replace the one inside of head-2.html include file.
