Getting Started with Gatsby

This integration guide follows the Quick Start Guide and assumes you have you have fully completed the "Hands-on" path. You should be able to consume the API by browsing the URL http://localhost:1337/api/restaurants.

If you haven't gone through the Quick Start Guide, the way you request a Strapi API with Gatsby remains the same except that you do not fetch the same content.

Create a Gatsby app

Create a basic Gatsby application using the Gatsby CLI.

gatsby new gatsby-app

Configure Gatsby

Gatsby is a Static Site Generator 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.

Example GET request

query {
  allStrapiRestaurant {
    edges {
      node {
        data {
          id
          attributes {
            name
            description
          }
        }
      }
    }
  }
}

Example response

{
  "data": {
    "allStrapiRestaurant": {
      "edges": [
        {
          "node": {
            "data":[
              {
                "id": 1,
                {
                  "attributes": {
                    "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 {
          data {
            id
            attributes {
              name
              description
            }
          }
        }
      }
    }
  }
`;

const IndexPage = () => (
  <StaticQuery
    query={query}
    render={data => (
      <ul>
        {data.allStrapiRestaurant.edges[0].node.data.map(restaurant => (
          <li key={restaurant.id}>{restaurant.attributes.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.

Example GET request

query {
  strapiCategory(data: { elemMatch: { id: { eq: 1 } } }) {
    data {
      id
      attributes {
        name
        restaurants {
          name
          description
        }
      }
    }
  }
}

Example response

{
  "data": {
    "strapiCategory": {
      "data": [
        {
          "id": 1,
          "attributes": {
            "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(data: { elemMatch: { id: { eq: 1 } } }) {
      data {
        id
        attributes {
          name
          restaurants {
            id
            name
            description
          }
        }
      }
    }
  }
`;

const IndexPage = () => (
  <StaticQuery
    query={query}
    render={data => (
      <div>
        <h1>{data.strapiCategory.data[0].attributes.name}</h1>
        <ul>
          {data.strapiCategory.data[0].attributes.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>.
