Setting up Gatsby with Strapi is straight forward, but while I was setting it up in M1 Mac, I encountered errors maybe due to software support issues as M1 is relatively new in the market right now. It took some time for me to figure out solutions and I want to save your day. Let's setup the Gatsby blog with Strapi now!
Apart from error and solutions, every step I mention in this blog is from the tutorial in the official strapi website.
Step 1: Install node v14
During the time I wrote this blog, v15 was the latest node version but not supported by strapi.
In command line type the following:
nvm install 14.16.0
Step 2: Install yarn
npm install --global yarn
Step 3: Create strapi-blog folder
Create a folder to store the backend (strapi) and frontend (gatsby) part of the blog. Following command will create a folder and move inside it.
take strapi-blog
# above command is short for
mkdir strapi-blog
cd strapi-blog
Step 4: Setup strapi with template
yarn create strapi-app backend --quickstart --template https://github.com/strapi/strapi-template-blog
There you go, we encounter our first error:
Error
ERR! sharp Prebuilt libvips 8.10.5 binaries are not yet available for darwin-arm64v8
Solution
Ref: Fix from github repo of sharp library
Install vips with brew
brew install vips
It took me around 14 minutes for it to install in my machine.
Install sharp
npm i sharp
Remove backend folder
When you run command to setup strapi with template, it creates backend folder to add all related files and folder for strapi to it. When you run the command again, you will strapi will complain that backend folder should be empty so let's empty it before strapi can even complain.
rm -rf backend
Run the command to setup strapi project again
yarn create strapi-app backend --quickstart --template https://github.com/strapi/strapi-template-blog
Command should run without any issue now.
Step 5: Setup admin user for strapi dashboard
As soon as the strapi setup is complete, dashboard will open in the browser and you will see the sign up page to setup the admin user.
Add necessary details and we won't need to deal with strapi anymore, apart from running the server for now.
Step 6: Setup Gatsby
Install gatsby cli
yarn global add gatsby-cli
Move out of backend folder
We need to setup gatsby project in separate folder so if you are inside backend folder, first you will have to move out from there
cd ..
Create gatsby project
Now you should be inside strapi-blog, run the following command to setup new gatsby project
gatsby new frontend
Error
wasm code commit Allocation failed - process out of memory
Solution
Switch to node v15
This issue is specifically in node v14 so switch to v15. If you haven't installed it in your machine yet, you can do so with following commands
# install node v15
nvm install 15.0.0
# use v15 locally
nvm use 15.0.0
Installation took around 10 minutes in my machine and I could hear the fan from Mac loudly (lol).
Run the command to setup gatsby project again
gatsby new frontend
Now the project should setup without any issue.
Step 7: Create .env file inside your gatsby project root
# move to gatsby project
cd frontend
# create .env file inside the project root
nano .env
Add following to the file:
GATSBY_ROOT_URL=http://localhost:8000
API_URL=http://localhost:1337
Step 8: Setup strapi for gatsby
Install gatsby-source-strapi
yarn add gatsby-source-strapi
Replace the content of gatsby-config.js with the following
require("dotenv").config({
path: `.env`,
});
module.exports = {
plugins: [
"gatsby-plugin-react-helmet",
{
resolve: `gatsby-source-filesystem`,
options: {
name: `images`,
path: `${__dirname}/src/images`,
},
},
{
resolve: "gatsby-source-strapi",
options: {
apiURL: process.env.API_URL || "http://localhost:1337",
contentTypes: ["article", "category", "writer"],
singleTypes: [`homepage`, `global`],
queryLimit: 1000,
},
},
"gatsby-transformer-sharp",
"gatsby-plugin-sharp",
{
resolve: `gatsby-plugin-manifest`,
options: {
name: "gatsby-starter-default",
short_name: "starter",
start_url: "/",
background_color: "#663399",
theme_color: "#663399",
display: "minimal-ui",
icon: `src/images/gatsby-icon.png`
},
},
"gatsby-plugin-offline",
],
};
Step 9: Replace the content of src/components/seo.js with the following:
import React from "react";
import PropTypes from "prop-types";
import { Helmet } from "react-helmet";
import { useStaticQuery, graphql } from "gatsby";
const SEO = ({ seo = {} }) => {
const { strapiGlobal } = useStaticQuery(query);
const { defaultSeo, siteName, favicon } = strapiGlobal;
// Merge default and page-specific SEO values
const fullSeo = { ...defaultSeo, ...seo };
const getMetaTags = () => {
const tags = [];
if (fullSeo.metaTitle) {
tags.push(
{
property: "og:title",
content: fullSeo.metaTitle,
},
{
name: "twitter:title",
content: fullSeo.metaTitle,
}
);
}
if (fullSeo.metaDescription) {
tags.push(
{
name: "description",
content: fullSeo.metaDescription,
},
{
property: "og:description",
content: fullSeo.metaDescription,
},
{
name: "twitter:description",
content: fullSeo.metaDescription,
}
);
}
if (fullSeo.shareImage) {
const imageUrl =
(process.env.GATSBY_ROOT_URL || "http://localhost:8000") +
fullSeo.shareImage.publicURL;
tags.push(
{
name: "image",
content: imageUrl,
},
{
property: "og:image",
content: imageUrl,
},
{
name: "twitter:image",
content: imageUrl,
}
);
}
if (fullSeo.article) {
tags.push({
property: "og:type",
content: "article",
});
}
tags.push({ name: "twitter:card", content: "summary_large_image" });
return tags;
};
const metaTags = getMetaTags();
return (
<Helmet
title={fullSeo.metaTitle}
titleTemplate={`%s | ${siteName}`}
link={[
{
rel: "icon",
href: favicon.publicURL,
},
{
rel: "stylesheet",
href: "https://fonts.googleapis.com/css?family=Staatliches",
},
{
rel: "stylesheet",
href:
"https://cdn.jsdelivr.net/npm/uikit@3.2.3/dist/css/uikit.min.css",
},
]}
script={[
{
src:
"https://cdnjs.cloudflare.com/ajax/libs/uikit/3.2.0/js/uikit.min.js",
},
{
src:
"https://cdn.jsdelivr.net/npm/uikit@3.2.3/dist/js/uikit-icons.min.js",
},
{
src: "https://cdnjs.cloudflare.com/ajax/libs/uikit/3.2.0/js/uikit.js",
},
]}
meta={metaTags}
/>
);
};
export default SEO;
SEO.propTypes = {
title: PropTypes.string,
description: PropTypes.string,
image: PropTypes.string,
article: PropTypes.bool,
};
SEO.defaultProps = {
title: null,
description: null,
image: null,
article: false,
};
const query = graphql`
query {
strapiGlobal {
siteName
favicon {
publicURL
}
defaultSeo {
metaTitle
metaDescription
shareImage {
publicURL
}
}
}
}
`;
Step 10: Style the blog
Create src/assets/css/main.css file and add the following:
a {
text-decoration: none !important;
}
h1 {
font-family: Staatliches !important;
font-size: 120px !important;
}
#category {
font-family: Staatliches !important;
font-weight: 500 !important;
}
#title {
letter-spacing: 0.4px !important;
font-size: 22px !important;
font-size: 1.375rem !important;
line-height: 1.13636 !important;
}
#banner {
margin: 20px !important;
height: 800px !important;
}
#editor {
font-size: 16px !important;
font-size: 1rem !important;
line-height: 1.75 !important;
}
.uk-navbar-container {
background: #fff !important;
font-family: Staatliches !important;
}
img:hover {
opacity: 1 !important;
transition: opacity 0.25s cubic-bezier(0.39, 0.575, 0.565, 1) !important;
}
Step 11: Remove useless components/pages
In command line, type the following:
rm src/components/header.js src/components/layout.css src/pages/page-2.js src/pages/using-typescript.tsx
Step 12: Replace the content of pages/index.js with the following code
import React from "react";
import { graphql, useStaticQuery } from "gatsby";
import Layout from "../components/layout";
import "../assets/css/main.css";
const IndexPage = () => {
const data = useStaticQuery(query);
return (
<Layout seo={data.strapiHomepage.seo}>
<div className="uk-section">
<div className="uk-container uk-container-large">
<h1>{data.strapiHomepage.hero.title}</h1>
</div>
</div>
</Layout>
);
};
const query = graphql`
query {
strapiHomepage {
hero {
title
}
seo {
metaTitle
metaDescription
shareImage {
publicURL
}
}
}
}
`;
export default IndexPage;
Step 13: Replace the content of components/layout.js with the following code
import React from "react";
import PropTypes from "prop-types";
import { StaticQuery, graphql } from "gatsby";
import Seo from "./seo";
const Layout = ({ children, seo }) => (
<StaticQuery
query={graphql`
query {
strapiHomepage {
seo {
metaTitle
metaDescription
shareImage {
publicURL
}
}
}
}
`}
render={(data) => (
<>
<Seo seo={seo} />
<main>{children}</main>
</>
)}
/>
);
Layout.propTypes = {
children: PropTypes.node.isRequired,
};
export default Layout;
Step 14: Create a ./src/components/nav.js with the following code
From code editor, create a new file and add the following:
import React from "react";
import { Link, StaticQuery, graphql } from "gatsby";
const Nav = () => (
<StaticQuery
query={graphql`
query {
strapiGlobal {
siteName
}
allStrapiCategory {
edges {
node {
slug
name
}
}
}
}
`}
render={(data) => (
<div>
<div>
<nav className="uk-navbar-container" data-uk-navbar>
<div className="uk-navbar-left">
<ul className="uk-navbar-nav">
<li>
<Link to="/">{data.strapiGlobal.siteName}</Link>
</li>
</ul>
</div>
<div className="uk-navbar-right">
<button
className="uk-button uk-button-default uk-margin-right"
type="button"
>
Categories
</button>
<div uk-dropdown="animation: uk-animation-slide-top-small; duration: 1000">
<ul className="uk-nav uk-dropdown-nav">
{data.allStrapiCategory.edges.map((category, i) => (
<li key={`category__${category.node.slug}`}>
<Link to={`/category/${category.node.slug}`}>
{category.node.name}
</Link>
</li>
))}
</ul>
</div>
</div>
</nav>
</div>
</div>
)}
/>
);
export default Nav;
Step 15: Import and use Nav component inside components/layout.js
Replace the code inside components/layout.js with the following:
import React from "react";
import PropTypes from "prop-types";
import { StaticQuery, graphql } from "gatsby";
import Nav from "./nav";
import Seo from "./seo";
const Layout = ({ children, seo }) => (
<StaticQuery
query={graphql`
query {
strapiHomepage {
seo {
metaTitle
metaDescription
shareImage {
publicURL
}
}
}
}
`}
render={(data) => (
<>
<Seo seo={seo} />
<Nav />
<main>{children}</main>
</>
)}
/>
);
Layout.propTypes = {
children: PropTypes.node.isRequired,
};
export default Layout;
Step 16: Blog listing UI
Install gatsby-image
npm install gatsby-image
NOTE
Tutorial in official strapi site is using gatsby-image which has already been deprecated but we will not update in this blog.
Create a new file components/card.js and add following code
import React from "react";
import { Link } from "gatsby";
import Img from "gatsby-image";
const Card = ({ article }) => {
return (
<Link to={`/article/${article.node.slug}`} className="uk-link-reset">
<div className="uk-card uk-card-muted">
<div className="uk-card-media-top">
<Img
fixed={article.node.image.childImageSharp.fixed}
imgStyle={{ position: "static" }}
/>
</div>
<div className="uk-card-body">
<p id="category" className="uk-text-uppercase">
{article.node.category.name}
</p>
<p id="title" className="uk-text-large">
{article.node.title}
</p>
<div>
<hr className="uk-divider-small" />
<div className="uk-grid-small uk-flex-left" data-uk-grid="true">
<div>
{article.node.author.picture && (
<Img
fixed={article.node.author.picture.childImageSharp.fixed}
imgStyle={{ position: "static", borderRadius: "50%" }}
/>
)}
</div>
<div className="uk-width-expand">
<p className="uk-margin-remove-bottom">
{article.node.author.name}
</p>
</div>
</div>
</div>
</div>
</div>
</Link>
);
};
export default Card;
Create a new file components/articles.js and add following code
import React from "react";
import Card from "./card";
const Articles = ({ articles }) => {
const leftArticlesCount = Math.ceil(articles.length / 5);
const leftArticles = articles.slice(0, leftArticlesCount);
const rightArticles = articles.slice(leftArticlesCount, articles.length);
return (
<div>
<div className="uk-child-width-1-2@s" data-uk-grid="true">
<div>
{leftArticles.map((article, i) => {
return (
<Card
article={article}
key={`article__left__${article.node.slug}`}
/>
);
})}
</div>
<div>
<div className="uk-child-width-1-2@m uk-grid-match" data-uk-grid>
{rightArticles.map((article, i) => {
return (
<Card
article={article}
key={`article__right__${article.node.slug}`}
/>
);
})}
</div>
</div>
</div>
</div>
);
};
export default Articles;
Replace the code inside pages/index.js with the following
import React from "react";
import { graphql, useStaticQuery } from "gatsby";
import Layout from "../components/layout";
import ArticlesComponent from "../components/articles";
import "../assets/css/main.css";
const IndexPage = () => {
const data = useStaticQuery(query);
return (
<Layout seo={data.strapiHomepage.seo}>
<div className="uk-section">
<div className="uk-container uk-container-large">
<h1>{data.strapiHomepage.hero.title}</h1>
<ArticlesComponent articles={data.allStrapiArticle.edges} />
</div>
</div>
</Layout>
);
};
const query = graphql`
query {
strapiHomepage {
hero {
title
}
seo {
metaTitle
metaDescription
shareImage {
publicURL
}
}
}
allStrapiArticle(filter: { status: { eq: "published" } }) {
edges {
node {
strapiId
slug
title
category {
name
}
image {
childImageSharp {
fixed(width: 800, height: 500) {
src
}
}
}
author {
name
picture {
childImageSharp {
fixed(width: 30, height: 30) {
src
}
}
}
}
}
}
}
}
`;
export default IndexPage;
Start gatsby app
To see what we have been building up till now, start the gatsby app and view the blog:
gatsby develop
Step 17: Article Page
Install react-markdown and react-moment
yarn add react-markdown react-moment moment
Replace the content inside gatsby.node.js with following code
exports.createPages = async ({ graphql, actions }) => {
const { createPage } = actions;
const result = await graphql(
`
{
articles: allStrapiArticle {
edges {
node {
strapiId
slug
}
}
}
}
`
);
if (result.errors) {
throw result.errors;
}
// Create blog articles pages.
const articles = result.data.articles.edges;
const ArticleTemplate = require.resolve("./src/templates/article.js");
articles.forEach((article, index) => {
createPage({
path: `/article/${article.node.slug}`,
component: ArticleTemplate,
context: {
slug: article.node.slug,
},
});
});
};
module.exports.onCreateNode = async ({ node, actions, createNodeId }) => {
const crypto = require(`crypto`);
if (node.internal.type === "StrapiArticle") {
const newNode = {
id: createNodeId(`StrapiArticleContent-${node.id}`),
parent: node.id,
children: [],
internal: {
content: node.content || " ",
type: "StrapiArticleContent",
mediaType: "text/markdown",
contentDigest: crypto
.createHash("md5")
.update(node.content || " ")
.digest("hex"),
},
};
actions.createNode(newNode);
actions.createParentChildLink({
parent: node,
child: newNode,
});
}
};
Create a file src/templates/article.js with the following code
import React from "react";
import { graphql } from "gatsby";
import Img from "gatsby-image";
import Moment from "react-moment";
import Layout from "../components/layout";
import Markdown from "react-markdown";
export const query = graphql`
query ArticleQuery($slug: String!) {
strapiArticle(slug: { eq: $slug }, status: { eq: "published" }) {
strapiId

publicURL
childImageSharp {
fixed {

}
}
}
author {
name
picture {
childImageSharp {
fixed(width: 30, height: 30) {
src
}
}
}
}
}
}
`;
const Article = ({ data }) => {
const article = data.strapiArticle;
const seo = {
metaTitle: article.title,
metaDescription: article.description,
shareImage: article.image,
article: true,
};
return (
<Layout seo={seo}>
<div>
<div
id="banner"
className="uk-height-medium uk-flex uk-flex-center uk-flex-middle uk-background-cover uk-light uk-padding uk-margin"
data-src={article.image.publicURL}
data-srcset={article.image.publicURL}
data-uk-img
>
<h1>{article.title}</h1>
</div>
<div className="uk-section">
<div className="uk-container uk-container-small">
<Markdown source={article.content} escapeHtml={false} />
<hr className="uk-divider-small" />
<div className="uk-grid-small uk-flex-left" data-uk-grid="true">
<div>
{article.author.picture && (
<Img
fixed={article.author.picture.childImageSharp.fixed}
imgStyle={{ position: "static", borderRadius: "50%" }}
/>
)}
</div>
<div className="uk-width-expand">
<p className="uk-margin-remove-bottom">

</p>
<p className="uk-text-meta uk-margin-remove-top">
<Moment format="MMM Do YYYY">{article.published_at}</Moment>
</p>
</div>
</div>
</div>
</div>
</div>
</Layout>
);
};
export default Article;
Since we edited gatsby-node.js, we will need to restart the gatsby server to view the new changes. You should be able to view the blog detail page now.
In command line where gatsby server is running, do the following:
# stop the server
control + c
# run the gatsby server again
gatsby develop
Step 18: Blog Category Page
Create a file src/templates/category.js with the following code
import React from "react";
import { graphql } from "gatsby";
import ArticlesComponent from "../components/articles";
import Layout from "../components/layout";
export const query = graphql`
query Category($slug: String!) {
articles: allStrapiArticle(
filter: { status: { eq: "published" }, category: { slug: { eq: $slug } } }
) {
edges {
node {
slug
title
category {
name
}
image {
childImageSharp {
fixed(width: 660) {
src
}
}
}
author {
name
picture {
childImageSharp {
fixed(width: 30, height: 30) {
...GatsbyImageSharpFixed
}
}
}
}
}
}
}
category: strapiCategory(slug: { eq: $slug }) {
name
}
}
`;
const Category = ({ data }) => {
const articles = data.articles.edges;
const category = data.category.name;
const seo = {
metaTitle: category,
metaDescription: `All ${category} articles`,
};
return (
<Layout seo={seo}>
<div className="uk-section">
<div className="uk-container uk-container-large">
<h1>{category}</h1>
<ArticlesComponent articles={articles} />
</div>
</div>
</Layout>
);
};
export default Category;
Replace the content inside gatsby.node.js with the following code
exports.createPages = async ({ graphql, actions }) => {
const { createPage } = actions;
const result = await graphql(
`
{
articles: allStrapiArticle {
edges {
node {
strapiId
slug
}
}
}
categories: allStrapiCategory {
edges {
node {
strapiId
slug
}
}
}
}
`
);
if (result.errors) {
throw result.errors;
}
// Create blog articles pages.
const articles = result.data.articles.edges;
const categories = result.data.categories.edges;
const ArticleTemplate = require.resolve("./src/templates/article.js");
articles.forEach((article, index) => {
createPage({
path: `/article/${article.node.slug}`,
component: ArticleTemplate,
context: {
slug: article.node.slug,
},
});
});
const CategoryTemplate = require.resolve("./src/templates/category.js");
categories.forEach((category, index) => {
createPage({
path: `/category/${category.node.slug}`,
component: CategoryTemplate,
context: {
slug: category.node.slug,
},
});
});
};
module.exports.onCreateNode = async ({ node, actions, createNodeId }) => {
const crypto = require(`crypto`);
if (node.internal.type === "StrapiArticle") {
const newNode = {
id: createNodeId(`StrapiArticleContent-${node.id}`),
parent: node.id,
children: [],
internal: {
content: node.content || " ",
type: "StrapiArticleContent",
mediaType: "text/markdown",
contentDigest: crypto
.createHash("md5")
.update(node.content || " ")
.digest("hex"),
},
};
actions.createNode(newNode);
actions.createParentChildLink({
parent: node,
child: newNode,
});
}
};
Restart the gatsby server to view new changes
In command line where gatsby server is running, do the following:
# stop the server
control + c
# run the gatsby server again
gatsby develop
You should now be able to view blogs listed by specific category.
Conclusion
Congratulations, you have successfully setup a gatsby blog with strapi. There was a small issue that I encountered after setting up the blog; in blog listing page, featured images of blog were not loading properly while they were loading correctly in the page where blogs are listed by category. Let me know how it goes for you!
Thanks for reading, if you have any confusion or suggestion, please comment below. See you soon in next blog!
