# Getting Started with Gatsby

This integration guide is following the Quick Start Guide. We assume that you have fully completed its "Hands-on" path, and therefore can consume the API by browsing this url (opens new window).

If you haven't gone through the Quick Start Guide, the way you request a Strapi API with Gatsby (opens new window) remains the same except that you will not fetch the same content.

# Create a Gatsby app

Create a basic Gatsby application using the Gatsby CLI (opens new window).

gatsby new gatsby-app

# Configure Gatsby

Gatsby is a Static Site Generator (opens new window) and will fetch your content from Strapi at build time. You need to configure Gatsby to communicate with your Strapi application.

yarn add gatsby-source-strapi
  • Add the gatsby-source-strapi to the plugins section in the gatsby-config.js file:
{
  resolve: "gatsby-source-strapi",
  options: {
    apiURL: "http://localhost:1337",
    collectionTypes: [
      "restaurant",
      "category",
    ],
    queryLimit: 1000,
  },
},

# GET Request your collection type

Execute a GET request on the restaurant Collection Type in order to fetch all your restaurants.

Be sure that you activated the find permission for the restaurant Collection Type.

Request

query {
  allStrapiRestaurant {
    edges {
      node {
        strapiId
        name
        description
      }
    }
  }
}

Response

{
  "data": {
    "allStrapiRestaurant": {
      "edges": [
        {
          "node": {
            "strapiId": 1,
            "name": "Biscotte Restaurant",
            "description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers."
          }
        }
      ]
    }
  }
}

# Example

./src/pages/index.js

import React from 'react';

import { StaticQuery, graphql } from 'gatsby';

const query = graphql`
  query {
    allStrapiRestaurant {
      edges {
        node {
          strapiId
          name
          description
        }
      }
    }
  }
`;

const IndexPage = () => (
  <StaticQuery
    query={query}
    render={data => (
      <ul>
        {data.allStrapiRestaurant.edges.map(restaurant => (
          <li key={restaurant.node.strapiId}>{restaurant.node.name}</li>
        ))}
      </ul>
    )}
  />
);

export default IndexPage;

Execute a GET request on the category Collection Type in order to fetch a specific category with all the associated restaurants.

Be sure that you activated the findOne permission for the category Collection Type.

Request

query {
  strapiCategory(strapiId: { eq: 1 }) {
    strapiId
    name
    restaurants {
      name
      description
    }
  }
}

Response

{
  "data": {
    "strapiCategory": {
      "id": "1",
      "name": "French Food",
      "restaurants": [
        {
          "name": "Biscotte Restaurant",
          "description": "Welcome to Biscotte restaurant! Restaurant Biscotte offers a cuisine based on fresh, quality products, often local, organic when possible, and always produced by passionate producers."
        }
      ]
    }
  },
  "extensions": {}
}

# Example

./src/pages/index.js

import React from 'react';

import { StaticQuery, graphql } from 'gatsby';

const query = graphql`
  query {
    strapiCategory(strapiId: { eq: 1 }) {
      id
      name
      restaurants {
        id
        name
        description
      }
    }
  }
`;

const IndexPage = () => (
  <StaticQuery
    query={query}
    render={data => (
      <div>
        <h1>{data.strapiCategory.name}</h1>
        <ul>
          {data.strapiCategory.restaurants.map(restaurant => (
            <li key={restaurant.id}>{restaurant.name}</li>
          ))}
        </ul>
      </div>
    )}
  />
);

export default IndexPage;

We can generate pages for each category.

  • Tell Gatsby to generate a page for each category by updating the gatsby-node.js file with the following:
exports.createPages = async ({ graphql, actions }) => {
  const { createPage } = actions;
  const result = await graphql(
    `
      {
        categories: allStrapiCategory {
          edges {
            node {
              name
            }
          }
        }
      }
    `
  );

  if (result.errors) {
    throw result.errors;
  }

  // Create blog articles pages.
  const categories = result.data.categories.edges;

  const CategoryTemplate = require.resolve('./src/templates/category.js');

  categories.forEach((category, index) => {
    createPage({
      path: `/category/${category.node.name}`,
      component: CategoryTemplate,
      context: {
        name: category.node.name,
      },
    });
  });
};
  • Create a ./src/templates/category.js file that will display the content of each one of your category:
import React from 'react';
import { graphql } from 'gatsby';

export const query = graphql`
  query Category($name: String!) {
    category: strapiCategory(name: { eq: $name }) {
      name
      restaurants {
        id
        name
      }
    }
  }
`;

const Category = ({ data }) => {
  const restaurants = data.category.restaurants;
  const category = data.category.name;

  return (
    <div>
      <h1>{category}</h1>
      <ul>
        {restaurants.map(restaurant => {
          return <li key={restaurant.id}>{restaurant.name}</li>;
        })}
      </ul>
    </div>
  );
};

export default Category;

You can find your restaurant categories by browsing http://localhost:8000/category/<name-of-category>.

Feel free to do the same for your restaurants!
