🎉 We are thrilled to introduce FastStore v2. If you are looking for documentation of the previous version of FastStore, please refer to FastStore v1.

Setting Up the Project

Now that your store is up and running after FastStore Onboarding, you're ready to set up your development environment and create a unique storefront that reflects your brand. Let's get started!

In this guide, you will:

Before you start

Required tooling

Before cloning your store's repository, ensure that you have the following tools on your machine:


To run your FastStore project, you must have the latest Node.js version or a version higher than 15.0.0.


We will use the yarn command-line interface to add functionalities to the store and also run tasks, such as starting a development server.

Install Yarn on macOS by running the following:
  brew install yarn
Install Yarn on Windows by running the following:
  npm install -g yarn

When developing your store's website, you will use Git (opens in a new tab) to push your code to the cloud. You will also use Git to download and install the required files for your project.

Visual Studio Code - Code Editor

When developing your store's website, you will need a code editor to write the code for your project, such as Visual Studio Code (a.k.a., VS Code). Visit the VS Code website, download and install the version appropriate to your operating system.


Although you might opt to use an alternative code editor, note that Visual Studio Code (opens in a new tab) might help you follow along with the FastStore documentation since our documentation may include screenshots from VS Code.

Enabling Developer Mode (Windows users)

We strongly recommend enabling Developer Mode when using the terminal for FastStore projects. Since FastStore projects rely on creating symlinks, this mode grants the necessary permissions and privileges, reducing the chance of errors during development. To activate Developer Mode, refer to Microsoft's official guide on Enabling your device for development (opens in a new tab).


Running the FastStore project as an Administrator is not recommended.

Step 1: Cloning the Store's Repository

  1. Open the terminal and navigate to the directory where you want to store your project.

For Windowns users we highly recommend to enable the Developer mode to run the terminal.

  1. Clone the repository created during the FastStore Onboarding by running the following command in the terminal:
    git clone https://github.com/vtex-sites/{storeName}

Replace {storeName} for your store's repository.

  1. Change into the working directory by running the following command:
cd {storeName}
  1. Install all the dependencies listed within the package.json file by running the following command:
yarn install
  1. Open up your FastStore project in any code editor of your choice.

Note that your store configuration was already set during the FastStore Onboarding. Therefore, there is no need to connect your project to your VTEX account. If you want to review these configurations, you can access the faststore.config.js file in the root directory of your project's repository.

Step 2: Running a local server

Let's check what the project looks like in a web browser so far.

  1. Start a local development server to serve your website:
  yarn dev

This may take a few minutes. Once your development server is ready, the command line will output a similar message as the following:

  ready - started server on, url: http://localhost:3000
  event - compiled client and server successfully in 333 ms (951 modules)

The dev command is part of the FastStore CLI, a pre-configured command line interface in your starter project. Using the CLI, this command enables you to execute code to keep your store's project up-to-date with the @faststore/core package.

  1. Now, open your favorite web browser and navigate to the localhost served, for example, http://localhost:3000 (opens in a new tab).


Congratulations! You have just created your very first FastStore store website! 🎉

While your local development server is running, you can preview any changes you make to your files, and saved changes will hot reload in the browser. To stop the development server, return to the terminal and press Ctrl + C. To restart it, run yarn dev again.

Step 3: Making the first change in your store frontend

Now that your store is up and running locally, let's make a simple change in the storefront.

Let's make the first level of customization which updates the store's theme. For this customization, we are going to use the Soft Blue theme.

  1. Create a new file named soft-blue.scss in src/themes. This is going to be the new theme of your store.

  2. Add the following styles to src/themes/soft-blue.scss:

// ----------------------------------------------------------
// Theme Soft Blue
// ----------------------------------------------------------
@layer theme {
  .theme {
  // --------------------------------------------------------
  // Colors (Branding Core)
  // --------------------------------------------------------
  --fs-color-main-0: #ecf0ff;
  --fs-color-main-1: #d8e2ff;
  --fs-color-main-2: #00419e;
  --fs-color-main-3: #002c71;
  --fs-color-main-4: #001947;
  --fs-color-accent-0: #ebdcff;
  --fs-color-accent-1: #8d50fd;
  --fs-color-accent-2: #732fe2;
  --fs-color-accent-3: #5900c8;
  --fs-color-accent-4: #4700a0;
  --fs-color-primary-bkg: var(--fs-color-main-4);
  --fs-color-primary-bkg-active: var(--fs-color-main-2);
  --fs-color-primary-bkg-light: var(--fs-color-main-0);
  --fs-color-primary-bkg-light-active: var(--fs-color-main-1);
  --fs-color-success-bkg: #cee8de;
  --fs-color-warning-bkg: #f6e0ba;
  --fs-color-text-display: var(--fs-color-main-4);
  --fs-color-action-bkg: var(--fs-color-accent-3);
  --fs-color-action-bkg-hover: var(--fs-color-accent-2);
  --fs-color-action-bkg-active: var(--fs-color-accent-1);
  // --------------------------------------------------------
  // Typography (Branding Core)
  // --------------------------------------------------------
  // FACE
  --fs-text-face-body: 'Lato', -apple-system, system-ui, BlinkMacSystemFont, sans-serif;
  // --------------------------------------------------------
  // Refinements
  // --------------------------------------------------------
  --fs-border-radius: 0.25rem;
  --fs-shadow: none;
  --fs-shadow-darker: 0 0 10px rgb(0 0 0 / 20%);
  --fs-shadow-hover: 0 1px 4px rgb(0 0 0 / 10%), 0 6px 8px rgb(0 0 0 / 10%);
  // --------------------------------------------------------
  // FS UI Components
  // --------------------------------------------------------
  // Add here the customizations for FastStore UI components.
    --fs-logo-width: 8rem;
    [data-fs-product-card] {
      --fs-product-card-border-color: transparent;
      --fs-product-card-border-color-hover: var(--fs-border-color-light);
      &[data-fs-product-card-bordered='true'] {
        --fs-product-card-border-color: var(--fs-border-color-light);
  1. Open the faststore.config.js file and changes the theme from custom-theme to soft-blue.
  theme: 'soft-blue',
  1. Restart the server and check in the browser the new theme applied to your store. You may need to refresh the page.



It is important to highlight that the store's logo is set through the Headless CMS.
