Starter template for Bootstrap 4 Beta with Sass and Gulp build system with these features:

• Handlebars HTML templates with Panini– Panini is a super simple flat file generator for use with Gulp. It compiles a series of HTML pages using a common layout. These pages can also include HTML partials, external Handlebars helpers, or external data as JSON.
• Sass compilation, prefixing with Autoprefixer, and JavaScript concatenation
• Built-in BrowserSync server - Will automatically reload your page when files are changed. It also live-injects CSS changes when you save a Sass file. This task runs continuously. Defaults to localhost.
• For production builds - CSS compression, JavaScript compression, Image compression

To use this template, your computer needs:

• Node.js (0.12 or greater) Node.js is used to run the build processes. https://nodejs.org/en/download/ Test: run node -v in the terminal
• Npm (Node comes with npm installed so you should have a version of npm.) Used to manage development dependencies. Test: run npm -v in the terminal
• Sass http://sass-lang.com/install Test: run sass -v in the terminal
• Gulp – task runner npm install -g gulp Test: run gulp -v in the terminal

** Before moving forward, please ensure you have all of the above installed. ** if so, please open a new terminal window or clear your current window and continue to template installation steps below.

1. cd into the Pattern Library and run npm install in your terminal - this command installs packages listed in the package.json file and any packages that it depends on. Packages are installed in the node_modules directory. a. Please do not modifiy anything in the node_modules directory. Note: the node_modules directory is not kept in source control.
2. To start your project, make sure you are in the Pattern Library folder and run gulp to start the “default” gulp task and bring up the local BrowserSync server. This step will also create the dist folder for you, run the Gulp tasks specified in the gulpfile.js file, and watch for file changes. When changes are ready to be comiited, stop the default gulp task, and commit to source control.
3. Your finished static mini site will be created in a folder called dist, viewable at this URL: http://localhost:3000
4. To create compressed, production-ready assets run gulp build. This will delete everything in the dist folder and recreate all of your complied files. Never make updates directly into the dist folder as these files get overridden each time. Note: The dist folder is not kept in source control.

• dist/: Compiled files. Note: Do not modify anything in this directory. Your changes will be overridden every time you run the build command.
• node_modules Front-end dependencies.
• src/ Folder contains all of your core, working files—static assets, pages, templates, etc. These assets are compiled to a distribution folder. This is a completely static HTML site.
• src/assets/ Sass files, JS files, images, and fonts go here.
• src/data/ External data.
• src/layouts/ HTML layouts (templates).
• src/pages/ Site pages.
• src/partials/ Handlebars partials.
• gulpfile.js Task definitions.
• package.json Handles the front-end dependencies.

• src/assets/scss/components/ This is where custom project components go. Import to app.scss folder.
• src/assets/scss/forms/ This is where form specific styles and components will go. Import to app.scss folder.
• src/assets/scss/mixins/ Custom mixins go here. Should be organized like components.
• src/assets/scss/pages/ Page specific overrides to components. This should be done sparingly. Think of generic UI elements rather than a page specific UI element. If used, these files should be much, much smaller than your component files - 20-30 lines max. Import to app.scss folder.
• src/assets/scss/vendors/ Third party library styles. These must be .scss files. If the third-party library does not have a scss version, create a new .scss file and copy and paste the CSS. Import to app.scss folder.
• src/assets/scss/_settings.scss Allows you to set core structural and visual elements of default components, this is where you will add any custom variables as well. Import to app.scss folder.
• src/assets/scss/app.scss This is where you will import your custom component files. Note: Do not write any scss here – every bit of CSS needs a home, more than likely this will be in components. Anything commented out gets ignored and does not get complied.
