Using in your project

  • First, ensure that node.js & npm are both installed. If not, choose your OS and installation method from this page and follow the instructions.
  • Next, use your command line to enter your project directory.
    • If this a new project (without a package.json file), start by running npm init. This will ask a few questions and use your responses to build a basic package.json file. Next, copy the "devDependencies" object into your package.json.
    • If this is an existing project, copy the contents of "devDependencies" into your package.json.
  • Now, copy any tasks you want from the "scripts" object into your package.json "scripts" object.
  • Finally, run npm install to install all of the dependencies into your project.

You're ready to go! Run any task by typing npm run task (where "task" is the name of the task in the "scripts" object). The most useful task for rapid development is watch. It will start a new server, open up a browser and watch for any SCSS or JS changes in the src directory; once it compiles those changes, the browser will automatically inject the changed file(s)!

List of available tasks

clean

rm -f dist/{css/*,js/*,images/*}

Delete existing dist files

autoprefixer

postcss -u autoprefixer -r dist/css/*

Add vendor prefixes to your CSS automatically

scss

node-sass --output-style compressed -o dist/css src/scss

Compile Scss to CSS

lint

eslint src/js

"Lint" your JavaScript to enforce a uniform style and find errors

uglify

mkdir -p dist/js && uglifyjs src/js/*.js -m -o dist/js/app.js && uglifyjs src/js/*.js -m -c -o dist/js/app.min.js

Uglify (minify) a production ready bundle of JavaScript

imagemin

imagemin src/images/* -o dist/images

Compress all types of images

icons

svgo -f src/images/icons && mkdir -p dist/images && svg-sprite-generate -d src/images/icons -o dist/images/icons.svg

Compress separate SVG files and combine them into one SVG "sprite"

serve

browser-sync start --server --files 'dist/css/*.css, dist/js/*.js, **/*.html, !node_modules/**/*.html'

Start a new server and watch for CSS & JS file changes in the dist folder

build:css

run-s scss autoprefixer

Alias to run the scss and autoprefixer tasks. Compiles Scss to CSS & add vendor prefixes

build:js

run-s lint concat uglify

Alias to run the lint, concat and uglify tasks. Lints JS, combines src JS files & uglifies the output

build:images

run-s imagemin icons

Alias to run the imagemin and icons tasks. Compresses images, generates an SVG sprite from a folder of separate SVGs

build

run-s build:*

Alias to run all of the build commands

watch:css

onchange 'src/**/*.scss' -- run-s build:css

Watches for any .scss file in src to change, then runs the build:css task

watch:js

onchange 'src/**/*.js' -- run-s build:js

Watches for any .js file in src to change, then runs the build:js task

watch:images

onchange 'src/images/**/*' -- run-s build:images

Watches for any images in src to change, then runs the build:images task

watch

run-p serve watch:*

Run the following tasks simultaneously: serve, watch:css, watch:js & watch:images. When a .scss or .js file changes in src or an image changes in src/images, the task will compile the changes to dist, and the server will be notified of the change. Any browser connected to the server will then inject the new file from dist

postinstall

run-s build watch

Runs watch after npm install is finished
