USWDS Compile

Simple Gulp 4.0 functions for copying USWDS static assets and transforming USWDS Sass into browser-readable CSS.

Requirements

Installation

Install @uswds/compile in the project root:

npm install @uswds/compile --save-dev

Usage

Overview

  1. Create a gulpfile.js file in the project root that includes the following:
    • Imported @uswds/compile package
    • Any project path settings you wish to modify (see Path settings, below)
    • Exports for the functions/tasks you need (see Functions, below)
  2. In the terminal run npx gulp [function]

Gulpfile setup

Create a file called gulpfile.js at the root of your project (or use an existing Gulpfile if one already exists). It needs to do the following

  • Import the @uswds/compile package
  • Set any project settings
  • Export the functions/tasks you need

Here's an example of how your gulpfile.js might look:

/* gulpfile.js */

const uswds = require("@uswds/compile");

/** 
 * Path settings
 * Set as many as you need
 */ 

uswds.paths.dist.css = './assets/css';
uswds.paths.dist.sass = './sass';

/** 
 * Exports
 * Add as many as you need
 */ 

exports.init = uswds.init;
exports.compile = uswds.compile;

Path settings

Use path settings to customize where USWDS Compile looks for USWDS source and outputs processed files.

Setting Default Description
paths.src.uswds "./node_modules/uswds/dist" Source location of the uswds package
paths.src.sass "./node_modules/uswds/dist/scss" Source location of the USWDS Sass
paths.src.theme "./node_modules/uswds/dist/scss/theme" Source location of the USWDS theme files (Sass entry point and starter settings files)
paths.src.fonts "./node_modules/uswds/dist/fonts" Source location of the USWDS fonts
paths.src.img "./node_modules/uswds/dist/img" Source location of the USWDS images
paths.src.js "./node_modules/uswds/dist/js" Source location of the USWDS compiled JavaScript files
paths.src.projectSass "./sass" Source location of any exisiting project Sass files outside of paths.dist.sass. The watch script will watch this directory for changes.
paths.dist.sass "./sass" Project destination for theme files (Sass entry point and settings)
paths.dist.img "./assets/uswds/images" Project destination for images
paths.dist.fonts "./assets/uswds/fonts" Project destination for fonts
paths.dist.js "./assets/uswds/js" Project destination for compiled JavaScript
paths.dist.css "./assets/uswds/css" Project destination for compiled CSS

Functions

Export USWDS Compile functions in your project's gulpfile.js to use them in your project.

Function Description
compile compileSass + compileIcons
compileIcons Build the USWDS icon sprite into paths.dist.img
compileSass Compile Sass into paths.dist.css
default watch
copyAll copySetup + copyAssets
copyAssets Copies all static assets: copyFonts + copyImages + copyJS
copyFonts Copy USWDS fonts to paths.dist.fonts
copyImages Copy USWDS images to paths.dist.img
copyJS Copy USWDS compiled JavaScript to paths.dist.js
copySetup Copy USWDS theme files (Sass entry point and settings files) from the uswds package to paths.dist.sass
init copyAll + compile
updateUswds copyAssets + compile
watch Compiles, then recompiles when there are changes to Sass files in paths.dist.sass and paths.src.projectSass

Running the compile functions

For any function you defined as an export in your gulpfile.js you can run npx gulp [function]

For example, if you have the following gulpfile.js:

/* gulpfile,js */

...

exports.compile = uswds.compile;
exports.watch = uswds.watch;
exports.init = uswds.init;
exports.update = uswds.updateUswds;
exports.default = uswds.watch;

With that setup, you could do the following in the terminal:

  • Compile Sass: npx gulp compile or npx gulp
  • Watch for changes and recompile: npx gulp watch
  • Initialize a new project: npx gulp init
  • Update USWDS statci assets and recompile: npx gulp update

Autoprefixer

We use Autoprefixer for maximum browser compatibility. We target the the following browsers. When you compile with the USWDS compiler, we will apply Autoprefixer to all compiled code.

Updating the USWDS icon sprite

After running either init or copyAssets, you'll find USWDS images in the paths.dist.img directory. Any icon SVG file in usa-icons diretory within the paths.dist.img directory will compile into the icon sprite when running the compileIcons function.

We'll be updating and improving the icon workflow in subsequent releases.
