Many, many thanks go out to Keith Cirkel for his post and his useful CLI tools!
- 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, run
npm installto 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.
rm -f dist/{css/*,js/*,images/*}
Delete existing dist files
postcss -u autoprefixer -r dist/css/*
Add vendor prefixes to your CSS automatically
node-sass --output-style compressed -o dist/css src/scss
Compile Scss to CSS
eslint src/js
"Lint" your JavaScript to enforce a uniform style and find errors
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 src/images/* -o dist/images
Compress all types of images
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"
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
run-s scss autoprefixer
Alias to run the scss and autoprefixer tasks. Compiles Scss to CSS & add vendor prefixes
run-s lint concat uglify
Alias to run the lint, concat and uglify tasks. Lints JS, combines src JS files & uglifies the output
run-s imagemin icons
Alias to run the imagemin and icons tasks. Compresses images, generates an SVG sprite from a folder of separate SVGs
run-s build:*
Alias to run all of the build commands
onchange 'src/**/*.scss' -- run-s build:css
Watches for any .scss file in src to change, then runs the build:css task
onchange 'src/**/*.js' -- run-s build:js
Watches for any .js file in src to change, then runs the build:js task
onchange 'src/images/**/*' -- run-s build:images
Watches for any images in src to change, then runs the build:images task
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
run-s build watch
Runs watch after npm install is finished
