Build a static blog using Gatsby (Typescript) and Strapi

Our community is looking for talented writers who are passionate about our ecosystem (jamstack, open-source, javascript) and willing to share their knowledge/experiences through our Write for the community program.

Introduction

There's a whole series in blog of tutorials on how to make blogs using Strapi with a lot of frontend frameworks: Gatsby, React, Next.js, Vue, Nuxt or Angular.

This time we are going to create a Gatsby blog using TypeScript, and adding one of coolest plugins in the ecosystem: gatsby-image.

Caveat emptor: this is a re write of the previous tutorial about creating a blog with STRAPI + Gatsby. So the design will be the same.

Goal

The goal here is to be able to create a simple static blog website using Strapi as the backend and Gatsby for the frontend, using TypeScript.

The source code is available on GitHub.

Prerequisites

This tutorial uses Strapi v3.0.0-beta.20.3.

You need to have node v.12 installed and that's all.

Setup

Create a strapi-gatsby-typescript-blog folder and get inside!

• mkdir strapi-gatsby-typescript-blog && cd strapi-gatsby-typescript-blog

Back-end setup

That's the easiest part, as since beta.9 Strapi has an excellent package create strapi-app that allows you to create a Strapi project in seconds without needing to install Strapi globally so let's try it out.

Note: for this tutorial, we will use yarn as your package manager.

• yarn create strapi-app backend --quickstart --no-run.

This single command line will create all you need for your back-end. Make sure to add the --no-run flag as it will prevent your app from automatically starting the server because SPOILER ALERT: we need to install some awesome Strapi plugins.

Now that you know that we need to install some plugins to enhance your app, let's install one of our most popular ones: the graphql plugin.

• yarn strapi install graphql

Once the installation is completed, you can finally start your Strapi server strapi dev and create your first Administrator.

Don't forget that Strapi is running on http://localhost:1337

Nice! Now that Strapi is ready, you are going to create your Gatsby application.

Front-end setup

The easiest part has been completed, let's get our hands dirty developing our blog with Gatsby!

Gatsby setup

First of all, you'll need to install the Gatsby CLI

Install the Gatsby CLI by running the following command:

• npm install -g gatsby-cli

Create a Gatsby frontend project by running the following command:

• gatsby new frontend https://github.com/resir014/gatsby-starter-typescript-plus

Once the installation is completed, you can start your front-end app to make sure everything went ok.

1cd frontend
2gatsby develop

Good start!

A little note about the starter: as you can see, we didn't use the default Gatsby starter repo, we used a TypeScript starter, so we don't have to add it ourselves ;)

We are not keeping the default Gatsby starter style but the one we used for every other tutorials of this series.

UIkit setup

We need to create a Seo component that will allow us to add UIkit cdn and Staatliches font

• Create this file: components/Seo.tsx (mind the file extension, TypeScript React/Gatsby files are .tsx) and add this code:

1import React from 'react'
2import PropTypes from 'prop-types'
3import { Helmet } from 'react-helmet'
4import { useStaticQuery, StaticQuery, graphql } from 'gatsby'
5
6interface StaticQueryProps {
7  site: {
8    siteMetadata: {
9      title: string
10      description: string
11      author: string
12      keywords: string
13    }
14  }
15}
16
17interface Props {
18  readonly title?: string
19  readonly children?: React.ReactNode
20}
21
22const SEO: React.FC<Props> = ({ children }) => (
23  <StaticQuery
24    query={graphql`
25      query SeoQuery {
26        site {
27          siteMetadata {
28            title
29            description
30          }
31        }
32      }
33    `}
34    render={(data: StaticQueryProps) => (
35      <Helmet
36        htmlAttributes={{
37          lang: `en`
38        }}
39        title={data.site.siteMetadata.title}
40        titleTemplate={`%s | ${data.site.siteMetadata.title}`}
41        link={[
42          {
43            rel: 'stylesheet',
44            href: 'https://fonts.googleapis.com/css?family=Staatliches'
45          },
46          {
47            rel: 'stylesheet',
48            href: 'https://cdn.jsdelivr.net/npm/uikit@3.2.3/dist/css/uikit.min.css'
49          }
50        ]}
51        script={[
52          {
53            src: 'https://cdnjs.cloudflare.com/ajax/libs/uikit/3.2.0/js/uikit.min.js'
54          },
55          {
56            src: 'https://cdn.jsdelivr.net/npm/uikit@3.2.3/dist/js/uikit-icons.min.js'
57          },
58          {
59            src: 'https://cdnjs.cloudflare.com/ajax/libs/uikit/3.2.0/js/uikit.js'
60          }
61        ]}
62        meta={[
63          {
64            name: `description`,
65            content: data.site.siteMetadata.description
66          },
67          {
68            property: `og:title`,
69            content: data.site.siteMetadata.title
70          },
71          {
72            property: `og:description`,
73            content: data.site.siteMetadata.description
74          },
75          {
76            property: `og:type`,
77            content: `website`
78          },
79          {
80            name: `twitter:card`,
81            content: `summary`
82          },
83          {
84            name: `twitter:creator`,
85            content: 'kilinkis'
86          },
87          {
88            name: `twitter:title`,
89            content: data.site.siteMetadata.title
90          },
91          {
92            name: `twitter:description`,
93            content: data.site.siteMetadata.description
94          }
95        ]}
96      />
97    )}
98  />
99)
100
101export default SEO

Let's explain that code a little bit:

Here we are using the React Helmet library (fun fact: it was created by the NFL devs). It handles the <head> component of our app. In this case, we import UIkit from a CDN, also the font and handle metadescriptions.

We also define two interfaces we need in order to use our components, these are StaticQueryProps and Props. StaticQueryProps describes the object returned in the query that fetches the site description. Props is very simple, it describes the kind of Props that the React Functional Component below expects.

We'll talk more about StaticQuery later on when we fetch our articles :)

In order to have a simple but beautiful blog we're going to add some style:

• Create a src/styles/main.ts file containing the following:

1export default `
2  a {
3    text-decoration: none !important;
4  }
5
6  h1 {
7    font-family: Staatliches !important;
8    font-size: 120px !important;
9  }
10
11  #category {
12    font-family: Staatliches !important;
13    font-weight: 500 !important;
14  }
15
16  #title {
17    letter-spacing: 0.4px !important;
18    font-size: 22px !important;
19    font-size: 1.375rem !important;
20    line-height: 1.13636 !important;
21  }
22
23  #banner {
24    margin: 20px !important;
25    height: 800px !important;
26  }
27
28  #editor {
29    font-size: 16px !important;
30    font-size: 1rem !important;
31    line-height: 1.75 !important;
32  }
33
34  .uk-navbar-container {
35    background: #fff !important;
36    font-family: Staatliches !important;
37  }
38
39  img:hover {
40    opacity: 1 !important;
41    transition: opacity 0.25s cubic-bezier(0.39, 0.575, 0.565, 1) !important;
42  }
43  .banner-bg {
44    position: absolute !important;
45    width: calc(100% - 2.5rem) !important;
46    height: 800px !important;
47}
48`

We are not going to explain that CSS, but feel free to change anything as you need :)

Now we need to include this file in out layout wrapper in order to make it available to our app:

• Open the file src/components/LayoutRoot.tsx and add the import after Normalize, like so:

import main from '../styles/main'

and finally, add our freshly imported main CSS to the Global component:

<Global styles={() => css(normalize, main)} />

Nice! Let's continue.

Strapi Setup

To connect Gatsby to a new source of data, you have to develop a new source plugin. Fortunately, several source plugins already exist, so one of them could fill your needs.

In this example, we are using Strapi as the backend provider, so we need a source plugin for Strapi APIs. Good news: we built it for you!

• Install gatsby-source-strapi by running the following command:

yarn add gatsby-source-strapi

This plugin needs to be configured.

• Replace the content of gatsby-config.js with the following code:

1'use strict'
2
3require('dotenv').config({
4  path: `.env.${process.env.NODE_ENV}`
5})
6
7module.exports = {
8  siteMetadata: {
9    title: 'My super blog',
10    description: 'Gatsby blog with Strapi',
11    author: {
12      name: 'Strapi team',
13      url: 'https://strapi.io/'
14    }
15  },
16  plugins: [
17    {
18      resolve: 'gatsby-source-strapi',
19      options: {
20        apiURL: process.env.API_URL || 'http://localhost:1337',
21        collectionTypes: [
22          // List of the Content Types you want to be able to request from Gatsby.
23          'article',
24          'category'
25        ],
26        queryLimit: 1000
27      }
28    },
29    'gatsby-transformer-json',
30    {
31      resolve: 'gatsby-plugin-canonical-urls',
32      options: {
33        siteUrl: 'https://gatsby-starter-typescript-plus.netlify.com'
34      }
35    },
36    'gatsby-plugin-emotion',
37    'gatsby-plugin-typescript',
38    'gatsby-plugin-sharp',
39    'gatsby-transformer-sharp',
40    'gatsby-plugin-react-helmet'
41  ]
42}

As you can see at the top of that code, we are using environment variables for our API url. So, create a .env.development file a the root of your frontend folder containing the following:

API_URL="http://localhost:1337"

Important note that we defined our API_URL for the Strapi API: http://localhost:1337 without a trailing slash and that we plan to query content types article and category

Alright! Gatsby is now ready to fetch data from Strapi, but first, we need to create some data in Strapi!

Designing the data structure

Finally! We are now going to create the data structure of our article by creating an Article content type.

• Dive in your Strapi admin panel and click on the Content-Types Builder link in the sidebar.

• Click on Create new collection type and call it article.

Now you'll be asked to create all the fields for your collection-type:

• Create the following ones:
  • title with type Text (required)
  • content with type Rich Text (required)
  • image with type Media (Single image) and (required)
  • published_at with type date (required)

Press Save! Here you go, your first content type has been created. Now you may want to create your first article, but we have one thing to do before that: Grant access to the article content type.

• Click on the Settings then Roles & Permissions and click on the public role.
• Check the article find and findone routes and save.

Awesome! You should be ready to create your first article right now and fetch it on the GraphQL Playground.

Now, create your first article !

Here's an example:

Great! Now you may want to reach the moment when you can actually fetch your articles through the API!

Go to http://localhost:1337/articles.

Isn't that cool! You can also play with the GraphQL Playground.

Create categories

You may want to assign a category to your article (news, trends, opinion). You are going to do this by creating another collection type in Strapi.

Create a new Collection Type, named category, with a Text field named category and a Relation field, that has Many to One relationship.

• Create three instances of this collection type, as shown below:

Press save!

• Create a new field in the Article content type which is a Relation Category has many Articles like below:

Click on the Settings then Roles & Permission and click on the public role. And check the category find and findone routes and save.

Now you'll be able to select a category for your article in the right sidebox.

Now that we are good with Strapi let's work on the frontend part!

Architecture

Before we can dive in, we have to clean the default Gatsby architecture by removing useless files with the following command:

rm src/pages/page.tsx src/pages/page-2.tsx

Since we are using TypeScript in this project, we are writting type safe code, and for that we are using Interfaces in most cases. To avoid duplicated code, we can declare interfaces in the typings.d.ts file. In this case, lets declare our Article interface so we can use it across our app.

• Add this at the top of your typings.d.ts file:

1interface Article {
2  node: {
3    id: number
4    strapiId: string
5    image: {
6      childImageSharp: {
7        fixed: FixedObject
8        fluid: FluidObject
9      }
10    }
11    category: {
12      name: string
13    }
14    title: string
15    content: string
16  }
17}

Now we need to update the layout/index.tsx file. Replace its content with the following code:

1import * as React from 'react'
2import { StaticQuery, graphql } from 'gatsby'
3
4import 'modern-normalize'
5import '../styles/normalize'
6
7import LayoutRoot from '../components/LayoutRoot'
8
9import ArticlesComponent from '../components/Articles'
10
11interface StaticQueryProps {
12  site: {
13    siteMetadata: {
14      title: string
15      description: string
16      keywords: string
17    }
18  }
19  allStrapiArticle: {
20    edges: Article[]
21  }
22}
23
24interface Props {
25  readonly title?: string
26  readonly children: React.ReactNode
27}
28
29const IndexLayout: React.FC<Props> = ({ children }) => (
30  <StaticQuery
31    query={graphql`
32      query IndexLayoutQuery {
33        site {
34          siteMetadata {
35            title
36            description
37          }
38        }
39        allStrapiArticle {
40          edges {
41            node {
42              strapiId
43              title
44              category {
45                name
46              }
47              image {
48                childImageSharp {
49                    fluid(maxWidth: 595, quality: 100) {
50                      ...GatsbyImageSharpFluid
51                      ...GatsbyImageSharpFluidLimitPresentationSize
52                    }
53                  }
54              }
55            }
56          }
57        }
58      }
59    `}
60    render={(data: StaticQueryProps) => (
61      <LayoutRoot>
62        <div className="uk-section">
63          <div className="uk-container uk-container-large">
64            <h1>Strapi blog</h1>
65            <ArticlesComponent articles={data.allStrapiArticle.edges} />
66          </div>
67        </div>
68      </LayoutRoot>
69    )}
70  />
71)
72
73export default IndexLayout

What is going on here ? Let me explain

Gatsby v2 introduces StaticQuery, a new API that allows components to retrieve data via a GraphQL query

1allStrapiArticle {
2  edges {
3    node {
4      strapiId
5      title
6      category {
7        name
8      }
9      image {
10        childImageSharp {
11            fluid(maxWidth: 595, quality: 100) {
12              ...GatsbyImageSharpFluid
13              ...GatsbyImageSharpFluidLimitPresentationSize
14            }
15          }
16      }
17    }
18  }
19}

This one will fetch all your articles from Strapi. Here, for each article we are querying: the id, title, category and image. The image object, as you can see, it's a little complex. This is because we are using gatsby-image here. This is one of the most popular plugins in Gatsby, mainly because it fixes these common problems virtually for free (taken from their docs):

• Resize large images to the size needed by your design.
• Generate multiple smaller images so smartphones and tablets don't download desktop-sized images.
• Strip all unnecessary metadata and optimize JPEG and PNG compression.
• Efficiently lazy load images to speed initial page load and save bandwidth.
• Use the "blur-up" technique or a "traced placeholder" SVG to show a preview of the image while it loads.
• Hold the image position so your page doesn't jump while images load.

I use it in every Gatsby project, I just think it helps in our endeavour of making the web a better place. You can read more about it and its API on the offical docs.

Then StaticQuery render your html with the fetched data:

1render={(data: StaticQueryProps) => (
2  <LayoutRoot>
3    <div className="uk-section">
4      <div className="uk-container uk-container-large">
5        <h1>Strapi blog</h1>
6        <ArticlesComponent articles={data.allStrapiArticle.edges} />
7      </div>
8    </div>
9  </LayoutRoot>
10)}

Now we need to update the components/Header.tsx file. Replace its content with the following code:

1import * as React from 'react'
2import { Link, StaticQuery, graphql } from 'gatsby'
3
4interface categoryInterface {
5  node: {
6    strapiId: number
7    name: string
8  }
9}
10
11interface HeaderProps {
12  title?: string
13}
14
15const Header: React.FC<HeaderProps> = ({ title }) => (
16  <div>
17    <div>
18      <nav className="uk-navbar-container" data-uk-navbar>
19        <div className="uk-navbar-left">
20          <ul className="uk-navbar-nav">
21            <li>
22              <Link to="/">Strapi Blog</Link>
23            </li>
24          </ul>
25        </div>
26
27        <div className="uk-navbar-right">
28          <ul className="uk-navbar-nav">
29            <StaticQuery
30              query={graphql`
31                query {
32                  allStrapiCategory {
33                    edges {
34                      node {
35                        strapiId
36                        name
37                      }
38                    }
39                  }
40                }
41              `}
42              render={data =>
43                data.allStrapiCategory.edges.map((category: categoryInterface, i: number) => {
44                  return (
45                    <li key={category.node.strapiId}>
46                      <Link to={`/category/${category.node.strapiId}`}>{category.node.name}</Link>
47                    </li>
48                  )
49                })
50              }
51            />
52          </ul>
53        </div>
54      </nav>
55    </div>
56  </div>
57)
58
59export default Header

There's not so much to explain here, but basically we add the two new Interfaces we need: categoryInterface and HeaderProps.

Then StaticQuery gets all the categories we defined in our backend.

1allStrapiCategory {
2  edges {
3    node {
4      strapiId
5      name
6    }
7  }
8}

And loops through them to create the Catergory navegation.

1render={data =>
2  data.allStrapiCategory.edges.map((category: categoryInterface, i: number) => {
3    return (
4      <li key={category.node.strapiId}>
5        <Link to={`/category/${category.node.strapiId}`}>{category.node.name}</Link>
6      </li>
7    )
8  })
9}

Now we need to use this component in your Layout component.

• Import and use your new Header component by pasting the following code inside your components/LayoutRoot.tsx file:

1import * as React from 'react'
2import Seo from './Seo'
3import Header from './Header'
4import { Global, css } from '@emotion/core'
5import normalize from '../styles/normalize'
6import main from '../styles/main'
7
8interface LayoutRootProps {
9  className?: string
10}
11
12const LayoutRoot: React.FC<LayoutRootProps> = ({ children, className }) => (
13  <>
14    <Seo />
15    <Global styles={() => css(normalize, main)} />
16    <Header />
17    <main>{children}</main>
18  </>
19)
20
21export default LayoutRoot

Also, we need to update the content of our index page, editing the content of ./pages.index.tsx. Replace its content with this:

1import * as React from 'react'
2
3import Page from '../components/Page'
4import IndexLayout from '../layouts'
5
6const IndexPage = () => (
7  <IndexLayout>
8    <Page></Page>
9  </IndexLayout>
10)
11
12export default IndexPage

At this point we can show the navigation header and the empty landing page, but wait... not so fast, if we try to compile the project now, it will fail because our gatsby-node file is outdated. We'll add the correct code there soon.

Note: The current code is not designed to display a lot of categories as one would encounter in a typical blog.

Great! But we still need to create some extra components we added in our main layout file.

Articles component

• Create a components/articles.tsx containing the following code:

1import React from 'react'
2import Card from './Card'
3
4interface ArticlesProps {
5  articles: Article[]
6}
7
8const Articles: React.FC<ArticlesProps> = ({ articles }) => {
9  const leftArticlesCount = Math.ceil(articles.length / 5)
10  const leftArticles = articles.slice(0, leftArticlesCount)
11  const rightArticles = articles.slice(leftArticlesCount, articles.length)
12
13  return (
14    <div>
15      <div className="uk-child-width-1-2" data-uk-grid>
16        <div>
17          {leftArticles.map(article => {
18            return <Card article={article} key={`article__${article.node.id}`} />
19          })}
20        </div>
21        <div>
22          <div className="uk-child-width-1-2@m uk-grid-match" data-uk-grid>
23            {rightArticles.map(article => {
24              return <Card article={article} key={`article__${article.node.id}`} />
25            })}
26          </div>
27        </div>
28      </div>
29    </div>
30  )
31}
32
33export default Articles

Here we are splitting our articles because we want to display some of them on the left side of the blog making them bigger and some on the right making them smaller. It's just a design thing.

Again, we are using another component: Card. Since Components are the building blocks of any React application, this is why you will find so many of them.

The benefit to this approach is that you end up doing less duplicate work by managing the components rather than managing duplicate content across different pages. This concept has become a real success and you are going to use it too!

• Create a components/card.js file containing the following code:

1import React from 'react'
2import { Link } from 'gatsby'
3import Img, { FixedObject } from 'gatsby-image'
4
5interface ArticleProps {
6  article: Article
7}
8
9const Card: React.FC<ArticleProps> = ({ article }) => {
10  return (
11    <Link to={`/article/${article.node.strapiId}`} className="uk-link-reset">
12      <div className="uk-card uk-card-muted">
13        <div className="uk-card-media-top">
14          <Img fluid={article.node.image.childImageSharp.fluid} />
15        </div>
16        <div className="uk-card-body">
17          <p id="category" className="uk-text-uppercase">
18            {article.node.category.name}
19          </p>
20          <p id="title" className="uk-text-large">
21            {article.node.title}
22          </p>
23        </div>
24      </div>
25    </Link>
26  )
27}
28
29export default Card

Awesome! Now let's updade the gatsby.node.js file to create the article and category pages and finish the tutorial :)

Article page

How can we create a page for each one of your article now? We'll need to use the createPages API. It will be called once the data layer is bootstrapped to let plugins create pages from data.

• Add the following code to your gatsby.node.js file:

1'use strict'
2
3const path = require('path')
4
5exports.createPages = async ({ graphql, actions }) => {
6  const { createPage } = actions
7  const result = await graphql(
8    `
9      {
10        articles: allStrapiArticle {
11          edges {
12            node {
13              strapiId
14            }
15          }
16        }
17        categories: allStrapiCategory {
18          edges {
19            node {
20              strapiId
21            }
22          }
23        }
24      }
25    `
26  )
27
28  if (result.errors) {
29    throw result.errors
30  }
31
32  // Create blog articles pages.
33  const articles = result.data.articles.edges
34  const categories = result.data.categories.edges
35
36  articles.forEach((article, index) => {
37    createPage({
38      path: `/article/${article.node.strapiId}`,
39      component: require.resolve('./src/templates/article.tsx'),
40      context: {
41        id: article.node.strapiId
42      }
43    })
44  })
45
46  categories.forEach((category, index) => {
47    createPage({
48      path: `/category/${category.node.strapiId}`,
49      component: require.resolve('./src/templates/category.tsx'),
50      context: {
51        id: category.node.strapiId
52      }
53    })
54  })
55}

We are fetching all your article and category ids in order to generate pages for each one of them It means that if you have 4 articles it will create 4 pages depending on the path you give, here it's path: /article/${article.node.strapiId}:

1/article/1
2/article/2
3/article/3
4/article/4

Just to keep it short, in that same step we added the node loop to create the category page. We'll work on that template soon.

Before going further you'll need to install two packages: one to display your content as Markdown and Moment

• Install react-markdown and react-moment by running the following command:

yarn add react-markdown react-moment moment

Now we need to create the page that will display each one of your article, you can see inside gatsby.node.js that here it's component: require.resolve("./src/templates/article.tsx")

• Create a src/templates/article.tsx file containing the following:

1import React from 'react'
2import { graphql } from 'gatsby'
3import Img, { FixedObject } from 'gatsby-image'
4
5import ReactMarkdown from 'react-markdown'
6
7import LayoutRoot from '../components/LayoutRoot'
8
9interface ArticleProps {
10  data: {
11    strapiArticle: {
12      image: {
13        childImageSharp: {
14            fixed: FixedObject
15          }
16      }
17      title: string
18      content: string
19    }
20  }
21}
22
23export const query = graphql`
24  query ArticleQuery($id: Int!) {
25    strapiArticle(strapiId: { eq: $id }) {
26      strapiId
27      title
28      content
29      published_at
30      image {
31        childImageSharp {
32            fixed(width: 660) {
33              ...GatsbyImageSharpFixed
34            }
35          }
36      }
37    }
38  }
39`
40
41const Article: React.FC<ArticleProps> = ({ data }) => {
42  const article = data.strapiArticle
43  return (
44    <LayoutRoot>
45      <div>
46        <div
47          id="banner"
48          className="uk-height-medium uk-flex uk-flex-center uk-flex-middle uk-background-cover uk-light uk-padding uk-margin"
49        >
50          <Img className="banner-bg" fixed={article.image.childImageSharp.fixed} />
51          <h1 className="uk-position-z-index">{article.title}</h1>
52        </div>
53
54        <div className="uk-section">
55          <div className="uk-container uk-container-small">
56            <ReactMarkdown source={article.content} />
57          </div>
58        </div>
59      </div>
60    </LayoutRoot>
61  )
62}
63
64export default Article

Category page

Remember we already added the category code in our gatsby.node.js file already? Okay, now we are going to use that.

We need to create the category template, as required here component: require.resolve("./src/templates/category.tsx")

• Create a src/templates/category.tsx file containing the following code:

1import React from 'react'
2import { graphql } from 'gatsby'
3
4import LayoutRoot from '../components/LayoutRoot'
5import ArticlesComponent from '../components/articles'
6
7interface CategoryProps {
8  data: {
9    articles: {
10      edges: Article[]
11    }
12    category: {
13      name: string
14    }
15  }
16}
17
18export const query = graphql`
19  query Category($id: Int!) {
20    articles: allStrapiArticle(filter: { category: { id: { eq: $id } } }) {
21      edges {
22        node {
23          strapiId
24          title
25          category {
26            name
27          }
28          image {
29            childImageSharp {
30                fluid(maxWidth: 595, quality: 100) {
31                  ...GatsbyImageSharpFluid
32                  ...GatsbyImageSharpFluidLimitPresentationSize
33                }
34              }
35          }
36        }
37      }
38    }
39    category: strapiCategory(strapiId: { eq: $id }) {
40      name
41    }
42  }
43`
44
45const Category: React.FC<CategoryProps> = ({ data }) => {
46  const articles = data.articles.edges
47  const category = data.category.name
48
49  return (
50    <LayoutRoot>
51      <div className="uk-section">
52        <div className="uk-container uk-container-large">
53          <h1>{category}</h1>
54          <ArticlesComponent articles={articles} />
55        </div>
56      </div>
57    </LayoutRoot>
58  )
59}
60
61export default Category

You can see that we are using the ArticlesComponent again! In fact we are displaying articles the same we as in the index, this is why we created a component, in order to not duplicate code ;)
