Kickoff your store with this boilerplate. This starter ships with the main FastStore configuration files you might need to get up and running blazing fast with the blazing-fast store for React.

⚠️ Before you start

As of Sep, 2022, this starter is still far from covering most basic cases found on VTEX. To summarize what we still do not support that is considered basic on the VTEX commerce platform, we prepared the list below. If the feature you want is listed, you can either wait for us to add support to the feature, or fork the repo and implement on your own. Note that, by forking the repo, you will miss new features and improvements we do in this repo and you will need a developer to backport the feature to your store. Finally, this list is a work in progress, so some features may be missing from both base.store starter and this list.

1. Multiple CMS Previews. Only one user is allowed to preview content from the CMS at a time. If two users preview any content from any page at the CMS, the previews are not consistent and one user may see data from the other.
2. Price Table
3. Internationalization
4. Shared Cart (Carrinho compartilhado)
5. Clear products that are our of stock from cart
6. GDPR (LGDP)
7. Shipping simulation
8. Sitemap
9. Promotions via utm

🚀 Quick start

0. Clone this repo

   Get up and running by cloning this repo.

   # Clone this repo into your machine
   npx degit vtex-sites/nextjs.store awesome.store

1. Install dependencies

   Install dependencies with yarn

   cd awesome.store/
   yarn

2. Setup faststore.config.js

   Choose the ecommerce platform provider of your choice in the store.config file and set the corresponding options. For instance, to connect to the VTEX platform on the store fashioneurope:

   module.exports = {
     platform: 'vtex',
   
     api: {
       storeId: 'fashioneurope'
       environment: 'vtexcommercestable'
     }
   }

3. Start developing

   Navigate into your new site’s directory and start it up.

   yarn dev

4. Open the source code and start editing!

   Your site is now running at http://localhost:3000!

   Open the awesome.store directory in your code editor of choice and edit src/pages/index.tsx. Save your changes and the browser will update in real-time!

💻 Code Structure

All code is inside the src folder. The code is split into folders that implement an MVC-like architecture.

The controller is inside the src/sdk folder. This is where you will find most logic for the application. This folder contains hooks for adding items to cart, making graphql queries, resizing images, etc. If you need to write a custom business logic this is probably the place to put this logic.

The views are written in the src/components folder and are subdivided into domain-specific components. Cart related items are inside the src/components/cart folder. Search and Product related components like facets, product summary, and search results are in their respective folders. Basic building blocks components are inside the UI folder. Components like button, checkbox, and modal are good candidates for the UI folder. Section components are those components that occupy a whole slice on the webpage and are desirable to be changed by a CMS. Section components are Product Gallery, Carousel, Shelf and Product description.

The model, in a website, is where the data fetching occurs. Since this project uses Jamstack, a crucial design decision was made to explicitly split where Static and Dynamic data are fetched. The files inside the src/pages folder use NextJS's File System Route API to declare routes and fetch static data.

To summarize:

1. src/pages: Routes are declared and static data is fetched.
2. src/views: Receives static data from src/pages, enriches this data with dynamic attributes, and render section components along with SEO tags.
3. src/components/sections: Receives necessary data and use domain-specific components (cart/product/search/ui) for rendering a slice on the web page.

✏️ Adding Components

What better than an example for learning the best practices while adding components? In this example, we will add a button component. Components live on the src/components folder. Each component may have, at most, 3 files: a component file, an export file, and a styling file. First, let's create a folder and the files.

mkdir src/components/ui/Button
touch src/components/ui/Button/Button.tsx
touch src/components/ui/Button/index.tsx

The index.tsx is just an export file, so its content is simple:

export { default } from './Button'

The real thing happens on Button.tsx. On this file let's define the component like:

interface Props {}

function Button(props: Props) {
  return <button {...props} />
}

export default Button

And, that's it! Now you have a working button that you can use anywhere on your project. FastStore, however, brings a handy library called @faststore/ui with built-in components to help you speed up your development. To use it, just change Button.tsx to:

import { Button as UIButton } from '@faststore/ui'
import type { ButtonProps } from '@faststore/ui'

interface Props extends ButtonProps {}

function Button(props: Props) {
  return <UIButton {...props} />
}

export default Button

Now, your Button component is powered by Store UI. However, if you try to use this on your app you will see that the button is lacking styles. To add styles, we will use CSS modules because they allow us to target data attributes. On your terminal, type:

touch src/components/ui/Button/button.scss

Now, on button.scss:

[data-fs-button] {
  display: inline-flex;
  align-items: center;
  justify-content: center;
}

This data-fs-button is a CSS data attribute selector. To know which selectors are available, check FastStore UI docs.

Now, include the component's CSS into the Store's CSS. Open src/styles/global/components.scss and import this CSS with:

// ...
@import 'src/components/ui/Button/button.scss';
// ...

For most components, you would stop here. However, buttons can have different variants. For instance, suppose you want to have a button component with primary and secondary variants. To add variants to the component, update Button.tsx:

import { Button as UIButton } from '@faststore/ui'
import type { ButtonProps } from '@faststore/ui'

interface Props extends ButtonProps {
  variant: 'secondary' | 'primary'
}

function Button({ variant, ...props }: Props) {
  return <UIButton data-button-variant={variant} {...props} />
}

export default Button

and then, on button.scss:

[data-fs-button][data-button-variant='primary'] {
  background: blue;
}

[data-fs-button][data-button-variant='secondary'] {
  background: pink;
}

You can also use classes, if you wanted to:

function Button({ variant, ...props }: Props) {
  return <UIButton className={variant} {...props} />
}

.primary[data-fs-button] {
  background: blue;
}

.secondary[data-fs-button] {
  background: pink;
}

Now we have a styled Button component that accepts different variants!! 🎉

Managing SVG Icons

Icons help build web pages by illustrating concepts and improving website navigation. However, using icons can decrease the page's performance. One option to avoid the decrease of the page's performance is to use SVGs from a single SVG file, located in /static/icons.svg, and load them with the ui/Icon component.

In the following steps, learn how to add and use a new SVG icon and avoid decreasing page performance while using an icon.

⚠️ Warning

This is a recommendation while using icons on a web page. Evaluate if this fits in your project.

Adding an SVG icon

1. In the SVG file, change the svg tag to symbol.
2. Add an id to the symbol. Remember to use an unique id and do not replicate it.
3. Remove unnecessary HTML/SVG properties to allow you to style and decrease the final file size, such as fill, stroke-width, width, height, and color.

An example adding Bell icon:

<svg style="display:none">
<symbol id="Bell" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 256 256"><rect width="256" height="256" fill="none"></rect><path d="M56.2,104a71.9,71.9,0,0,1,72.3-72c39.6.3,71.3,33.2,71.3,72.9V112c0,35.8,7.5,56.6,14.1,68a8,8,0,0,1-6.9,12H49a8,8,0,0,1-6.9-12c6.6-11.4,14.1-32.2,14.1-68Z" fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round"></path><path d="M96,192v8a32,32,0,0,0,64,0v-8" fill="none" stroke="currentColor" stroke-linecap="round" stroke-linejoin="round"></path></symbol>
</svg>

Using an SVG icon

1. Get the icon's id that you created in the SVG icon file.
2. Add the id in the React component that you desire to use the SVG icon. For example

// src/components/ui/MyIconButton/MyIconButton.tsx
import Icon from 'src/components/ui/Icon' // this path can be outdated.

function ButtonIcon() {
  return (
    <button>
      <Icon name="<<symbol_id>>" weight="thin" />
    </button>
  )
}

export default ButtonIcon

This project uses SVGs from Phosphor icons.

🖊️ Styling Components

Our customized themes are based on Design Tokens using CSS Variables or a CSS class for each token. Today, we have the following files in the src/styles folder:

tokens.scss

Here you'll find the basic structure to build your theme (font base, color palette, spacing, color-text, body background color...), feel free to update it with your brand guidelines.

Colors

We suggest using a color palette of 3 colors and its gradation: primary, secondary and neutral.

We also listed a couple of customizable tokens so you can easily change your body background, for example.

If you feel the need to edit some of the color decisions, you can enter tokens.scss and update the semantical tokens. E.g.:

--fs-border-color: var(--fs-color-neutral-4); // Current
--fs-border-color: var(--fs-color-neutral-5); // Updated

Typography

We use the Modular Scale setting to create our text-sizes. If you want to change it, just set the --fs-text-size-base and the scale ratio.

Spacing

The spacing scale is based on rem sizes, so it will remain consistent if you change the --fs-text-size-base.

layout.scss

List of classes used to create default page grid.

.layout__content // Should be used for sections that fit centered on the grid.
.layout__section // This class only adds default vertical margins for page sections.

typography.scss

For the typography-related styles, we decided to use classes to add extra stylings like font-weight and line-height. In this file, you'll see all the classes for titles, paragraphs, and default settings on the body. You can create new ones here if needed.

🍒 Adding queries

We use graphql-codegen to pre-process GraphQL queries. This compilation generates TypeScript typings and configurations for our graphql server under the folder @generated/graphql. This means we can statically analyse your code in search of bugs and secure your graphql server before each deploy. If, however you need to change any GraphQL Fragment, Query or Mutation, you will need to regenerate the whole thing. To do this, open your terminal and type

$ yarn dev

Now, after the nextjs development server is up and running, open another terminal and run

$ yarn generate

That's it! you have just regenerated all graphql queries/fragments for your application and the new data you requested should be available to your component.

Pro tip: Pass -w to the yarn generate command so it watches for changes and you don't need to run this command multiple times.

CMS Integration

This store is integrated with VTEX headless CMS.

The page rendered with CMS is:

• index page: pages/index.tsx

CMS configs

It's possible to change the CMS tenant and workspace at faststore.config.js.

🎓 Learning the Frameworks

Looking for more guidance? Full documentation for FastStore lives on this GitHub repository. Also, for learning NextJS, take a look at the NextJS Website, they have plenty of tutorials and examples in there.

⚡ Performance & QA

This project has strict performance budgets. Right out of the box, this project performs around 95 on Google's Page Speed Insights website, which usually is way more strict than your laptop's chrome lighthouse. Every time you commit to the repository, our QA bots will run and evaluate your code quality. We recommend you NEVER put in production a code that breaks any of the bots. If a bot breaks and still you need to put the code into production, change the bot config (lighthouserc.js, cypress.config.ts) to make it pass and merge. This way you ensure your website will keep performing well during the years to come.

Adding third party scripts

Adding third-party scripts to a webpage usually makes it slow. To maintain great performance while third-party scripts are added, this project uses Partytown, a lazy-load library that helps relocate intensive scripts into a web worker and off of the main thread.

To add scripts using Partytown, add the type="text/partytown" to the script tag and make sure to add it before the Partytown script or component. Some third-party scripts execute expensive computations that may require some time to run, making pages few slow. If that's the case, wrap those in a function and reference it on the Partytown forward prop. By doing this, Partytown will run this function on a web worker so it doesn't block the main thread.

export const onRenderBody = ({ setHeadComponents }) => {
  // ...
  setHeadComponents([
    <script type="text/partytown">
      window.expensiveFunction = function() {/* expensive computation used by custom-script */}
    </script>
    <script key="custom-script" src="*://domain/path" type="text/partytown" />,
    <Partytown key="partytown" forward={["expensiveFunction"]} />
  ])
  // ...
}
