Getting started


  1. This development stack uses Node, so make sure you have it installed.
  2. Install Gulp globally:
npm install -g gulp


  1. Clone the repository: git clone ./PROJECT_NAME

  2. Install package dependencies with npm install under the root of your PROJECT_NAME folder.

  3. Configure the project. Do not forget to change the respective keys in package.json according to your project’s info, and setup a unique listening port in ./gulp/config.js.

Project structure

Following a certain file and folder structure keeps development, maintenance and debugging processes much easier when switching from project to project based on the same development stack.

  • dist/

    Build (production) folder generated and changed automatically by various Gulp tasks. Contains production-ready compiled CSS (dist/css), JavaScript (dist/js), graphics (dist/gfx) and HTML. Should not be edited manually.

  • gulp/

    • tasks/ The list of Gulp tasks. Each task is responsible for handling automation for different file types (i.e. styles.js compiles SCSS to CSS, and serve.js launches a local server for development). Do not edit unless you know what you are doing.

    • config.js Global Gulp configuration, consisting of declaring environment and folder/file paths. While we would not recommend to change the project structure references, you may and should customize such keys as PORT or TITLE, which are unique for each project.

    • environment.js Determines current working environment (DEVELOPMENT or PRODUCTION).

  • src/

    Development folder. This is where all the action happens.

    • api/
      • api.js Entry point of dummy data for api server.
    • app/ JavaScript source files.
      • components/ React-driven components.
      • modules/ Vanilla JS classes.
      • store/ Redux store.
      • utilities/ Small helpers for everyday routine.
      • app.js Entry point for JS bundling.
      • factory.js Functions for initializing one instance of module on multiple containers.
      • init.js Functions for initializing one instance of module per one container.
      • render.js Functions for initilizing React components.
    • gfx/
      • svg/
        • sprites/ Folder for SVG sprites, where each nested folder represents a sprite name, and containing files - the icons bundled into that sprite.
        • example.svg Single SVG icons, optimized and outputted individually for direct usage.
      • image.png
    • styles/
      • base/ Base components used by Styleguide.
      • bootstrap/ Bootstrap overrides.
      • components/ Custom components.
      • critical.scss Critical CSS
      • main.scss Entry point for SCSS compiling.
      • variables.scss Custom variables
    • tpl/
      • components/
      • helpers/
      • layouts/
      • PAGE.nunj Template page written in Nunjucks and compiled to dist/PAGE.html.
  • / (root files)

    A brief summary of dev stack root files purpose.

    • .babelrc

      Babel configuration. Primarily used to specify presets for plugins for JavaScript compiling.

      Further info

    • .editorconfig

      A definition of coding styles for different code editors and IDEs. You can specify what configuration (indent size, charset, trim whitespaces, ...) should be used for what files.

      Further info

    • .eslintrc.js

      Eslint configuration. Primarily used to specify and configure rules of JavaScript linting.

      Further info

    • .gitattributes

      Path-specific settings used by Git. Settings that Git applies to certain subdirectories or subsets of files - for example EOL (End Of Line) setting.

      Further info

    • .gitignore

      Contains patterns that are matched against file names in your Git repository to determine whether or not they should be ignored (commited).

      Further info

    • .stylelintrc

      Stylelint configuration. Primarily used to specify and configure rules of CSS (SCSS) linting.

      Further info

    • circle.yml

      CircleCI configuration. How to set up and test your project.

      Further info


      Project workflow guideline. How to create branches, write commits or assign pull requests.

      Further info

    • gulpfile.js

      Gulp configuration and definition of automation tasks.

      Further info


      Open source license of Git repository. It enables others to freely use, change and distribute the project in the repository.

      Further info

    • package-lock.json

      NPM manifest. Automatically generated with change of node_modules or package.json if working with NPM. Holds information about which versions of each dependency were installed in order to get consistent installs across machines.

      Further info

    • package.json

      NPM packages specifics. It lists the packages (with their versions) your project depends on.

      Further info


      It's me!

    • yarn.lock

      Yarn manifest. Automatically generated with change of node_modules or package.json if working with Yarn. Holds information about which versions of each dependency were installed in order to get consistent installs across machines.

      Further info



To start your development process, run gulp --dev in the terminal. This will prepare the project for the work and launch watch tasks to update the files on-the-fly as you work. A --dev flag will notify the automatization tasks to add or omit certain steps (i.e. your JavaScript files are not minified while in development mode).

API mock server

If you want to start also an API server, run gulp --dev --api. This server will run on different port which is defined in gulp/config.js as API_PORT.


If you want to start Mokker, run gulp server. This server will run on different port which is defined in gulp/config.js as MOCK_PORT.

Remove built targets

If you want to revert back to a fresh state without built files, run

gulp clean

It will remove the dist/ folder and all built targets in src/.

Production build

To prepare production-ready files, run gulp and grab built assets from dist folder.

Updates from devstack to your project

  • create branch in your project’s repo (eg. devstack-update)
  • add devstack as a remote to your project (git remote add devstack
  • fetch remote (git fetch devstack)
  • merge branch from devstack remote to devstack-update (use --allow-unrelated-histories if necessary)
  • merge your project’s master to devstack-update
  • solve eventual conflicts
  • push the devstack-update branch
  • create PR from devstack-update to your master

Debugging with Visual Studio Code Debugger for Chrome

Support for extension Debugger for Chrome is enabled! Big thanks to roblourens

  1. Install extension Debugger for Chrome
  2. Run project in development mode
  3. Run Debugger for Chrome by F5 key (in Windows)
