Recipes: Pages and Layouts

Add pages to your Gatsby site, and use layouts to manage common page elements.

Project structure

Inside a Gatsby project, you may see some or all of the following folders and files:

Some notable files and their definitions:

• gatsby-config.js — configure options for a Gatsby site, with metadata for project title, description, plugins, etc.
• gatsby-node.js — implement Gatsby’s Node.js APIs to customize and extend default settings affecting the build process
• gatsby-browser.js — customize and extend default settings affecting the browser, using Gatsby’s browser APIs
• gatsby-ssr.js — use Gatsby’s server-side rendering APIs to customize default settings affecting server-side rendering

Creating pages automatically

Gatsby core automatically turns React components in src/pages into pages with URLs. For example, components at src/pages/index.js and src/pages/about.js would automatically create pages from those filenames for the site’s index page (/) and /about.

Prerequisites

• A Gatsby site
• The Gatsby CLI installed

Directions

1. Create a directory for src/pages if your site doesn’t already have one.
2. Add a component file to the pages directory:

3. Run gatsby develop to start the development server.
4. Visit your new page in the browser: http://localhost:8000/about

Linking between pages

Routing in Gatsby relies on the <Link /> component.

Prerequisites

• A Gatsby site with two page components: index.js and contact.js
• The Gatsby <Link /> component
• The Gatsby CLI to run gatsby develop

Directions

1. Open the index page component (src/pages/index.js), import the <Link /> component from Gatsby, add a <Link /> component above the header, and give it a to property with the value of "/contact/" for the pathname:

2. Run gatsby develop and navigate to the index page. You should have a link that takes you to the contact page when clicked!

Note: Gatsby’s <Link /> component is a wrapper around @reach/router’s Link component. For more information about Gatsby’s <Link /> component, consult the API reference for <Link />.

Creating a layout component

It’s common to wrap pages with a React layout component, which makes it possible to share markup, styles, and functionality across multiple pages.

Prerequisites

• A Gatsby Site

Directions

1. Create a layout component in src/components, where child components will be passed in as props:

2. Import and use the layout component in a page:

Creating pages programmatically with createPage

You can create pages programmatically in the gatsby-node.js file with helper methods Gatsby provides.

Prerequisites

• A Gatsby site
• A gatsby-node.js file

Directions

1. In gatsby-node.js, add an export for createPages

2. Destructure the createPage action from the available actions so it can be called by itself, and add or get data

3. Loop through the data in gatsby-node.js and provide the path, template, and context (data that will be passed in the props’ pageContext) to createPage for each invocation

4. Create a React component to serve as the template for your page that was used in createPage

5. Run gatsby develop and navigate to the path of one of the pages you created (like at http://localhost:8000/Fido) to see the data you passed it displayed on the page
