Gulp 4 Bootstrap Sass BrowserSync Boilerplate

Gulp 4 Bootstrap Sass BrowserSync Boilerplate is a starter project from Themesberg that combines Gulp 4, Bootstrap 4, and Sass with BrowserSync to give front-end developers a live-reloading build workflow. Its single core function is to turn a cloned repository into a running local development server with one gulp command, automating Sass compilation and browser refresh.

What is the Gulp 4 Bootstrap Sass BrowserSync Boilerplate?

This boilerplate is the companion project files for the Themesberg blog tutorial "Gulp 4, Bootstrap, Sass and BrowserSync setup tutorial." It takes plain HTML, Sass (.scss) stylesheets, and the Bootstrap 4 framework as inputs, and produces a compiled website served at http://localhost:3000 with automatic browser reloading. The repository is hosted on GitHub under the Themesberg organization and includes everything needed to run the setup: a package.json for npm dependencies, a Gulpfile with Gulp 4 tasks, and the project structure shown in the tutorial.

Key Features

• Gulp 4 task runner — Uses the Gulp 4 API to define tasks that compile Sass and orchestrate BrowserSync, giving you a modern Node.js-based build pipeline.
• Bootstrap 4 included — Bootstrap 4 is part of the dependency set, so you can use its grid system, components, and utility classes right away.
• Sass preprocessing — The workflow compiles .scss source files into browser-ready CSS, supporting variables, mixins, partials, and other Sass language features.
• BrowserSync live reload — Starts a local server on port 3000 and watches project files, automatically reloading the browser whenever you edit HTML or Sass.
• Quick start commands — Two commands get you running: npm install to install dependencies and gulp to start the server and file watcher.
• Tutorial alignment — The files match the Themesberg tutorial step by step, making it easy to compare your own setup against a working example.

Who is it for?

• Front-end developers learning build tools — You can study a minimal Gulp 4 configuration that handles real tasks like Sass compilation and live reload without the complexity of Webpack.
• Bootstrap customizers — Because Sass is wired in, you can edit Bootstrap variables and recompile to create customized theme styles rather than hand-writing overrides.
• Themesberg tutorial readers — Anyone following the companion blog tutorial gets the exact starting files referenced in the instructions, eliminating setup guesswork.

What can you do with it?

• Rapid prototyping: Write Bootstrap 4 markup and custom Sass, then watch the browser update instantly on save through BrowserSync.
• Bootstrap theme development: Override Bootstrap's Sass variables to generate a unique color palette and test component changes in real time.
• Learning Gulp 4 pipelines: Inspect the Gulp tasks, modify them to add minification or source maps, and use them as a base for larger front-end projects.

How does it work?

First, clone or download the repository. Second, run npm install in the project directory to fetch all dependencies from package.json. Third, run gulp — this starts a local server at http://localhost:3000, compiles your Sass files, and watches for changes. Whenever you edit a source file, BrowserSync pushes the update to the browser without a manual refresh.

FAQ

Do I need Node.js to use this boilerplate?

Yes. Running npm install and gulp requires Node.js and npm, since Gulp 4 is a Node.js-based task runner and dependencies are installed through npm.

What port does the development server use?

The default local server runs on http://localhost:3000. This is the address BrowserSync opens when you run gulp.

Is this project free?

The files are published publicly on GitHub by Themesberg as part of a free tutorial, so you can download and use them to follow along with the tutorial. No purchase or account is required.
