Building a Blog Using Nuxt.js and Ghost

Building a Blog Using Nuxt.js and Ghost. In this tutorial, you’ll learn how to set up Ghost on your local machine and use its API to build a blog in Nuxt.js

Ghost is an open-source platform for building and running a modern online publication. It powers blogs, magazines, and journalists from Zappos to Sky News.

In this tutorial, you’ll learn how to set up Ghost on your local machine and use its API to build a blog in Nuxt.js.

Why Should You Use Ghost?

Now, the question remains: “Why should you use Ghost in the first place?” Here are some benefits it has over other content management systems.

Extensible and rich text editor

Ghost provides a familiar editing environment that enables a seamless authoring experience that allows writers to focus on creating content.

You can imagine it as a mix of Medium’s editor and Slack’s integration which makes it very easy to edit your articles while providing a lot of great functionality. The editor is also fully extensible thanks to MobileDoc.

Free and open source

Ghost is an entirely open-source application that can be used with nearly any modern technology stack.

It provides a local installation setup for both Windows and Linux, and even its own Docker image. You can also pay for it if you would like a Ghost Pro cloud solution.

Optimized distribution channels

Publish once, distribute everywhere.

This principle is a core building block of Ghost and enables the user to easily control SEO (Search Engine Optimization), define meta tags, and it even provides integration for tools like RSS readers, email, and Slack.

Complete JSON API

Ghost’s JSON API gives you full control over which data to get, set, and display.

It gives you the opportunity to build entire blogs or other publishing apps on top of it, and completely customize the reading experience. You will use the API in this tutorial to get the data into your custom Nuxt.js blog.

Ghost Setup

Now that you have an overview of why you should use Ghost and where it can be useful, let’s take a look at how you can install Ghost on your local machine.

The installation is split into two parts:

  1. Installing Ghost on your local machine (two different ways).
  2. Basic Ghost configuration so you can use the API.

Installation

Windows

The installation process on Windows is straightforward and can be done using the Ghost-CLI (Command Line Interface), which can be downloaded using the Node package manager (npm) or Yarn.

npm install [email protected] -g

Once installed, use the following command to verify your installation:

ghost -v

After successfully installing the CLI, you can continue by installing a local version of Ghost using the following command in an empty directory:

ghost install local

Your Ghost site should now be visible on [http://localhost:2368](http://localhost:2368.). You can also verify that it is running using the ghost ls command.

That is it for the Windows installation. Here are some useful commands to control your Ghost instances:

  • ghost stop: To stop Ghost.
  • ghost start: To start Ghost.
  • ghost log: Views logs.

Docker

Another way to install Ghost on your local machine is through the official Docker image.

If you have no previous experience with Docker, I would recommend using the installation guide above because it can be hard to understand at first.

Here is the command to run a basic Ghost installation:

docker run -d --name ghost -p 2368:2368 ghost

This command runs a Docker container with the official Ghost image and publishes the port 2368, so that you can use the container on your host system without having to type the IP address of the container before the port.

Your instance should now run on [http://localhost:2368](http://localhost:2368) and should be identical to that of the previous installation.

You need to keep one more thing in mind when you install Ghost using Docker. And that is how you can preserve the state of your application when your container lifecycle changes. This is done by defining volumes.

docker run -d --name ghost -p 2368:2368 -v local/path/data:/var/lib/ghost/content ghost

If you want more information on how to set up Ghost using Docker, I would recommend checking out the documentation for the official image.

Ubuntu

I have never personally installed Ghost on Ubuntu, which is why I will just link to the official documentation instead.

Basic Configuration

Now that the installation is complete and you have Ghost running on your local machine, let’s continue with the basic configuration of your Ghost project.

The first screen you see when you visit [http://localhost:2368](http://localhost:2368) should look something like this:

Here, you just need to click create an account and continue with the setup.

Next up, you need to create a user. Just fill in the form and then continue.

The next step is to add other writers, which we will skip for now. After clicking continue, you should see a window that looks similar to this one:

This is image title

The next step is to enable the API so you can start developing your front end in Nuxt.js. You can do so by navigating to integrations and click on Add custom integration.

Now you just need to give it a name, in my case, API.

This is image title

That is it, you should see your content and admin API keys, which you will use to get the data from the API into your front end.

Ghost API

Perfect, now that the set up is completed, let’s take a look at the Ghost Content API and all the possibilities and endpoints that are available.

The Ghost RESTful API delivers published content to users and can be accessed in a read-only manner by any client to render the website. Access control is managed via an API key and provides an SDK which makes it easy to filter and query your data.

Endpoints

All endpoints of the Content API use the GET keyword and return JSON data. Here is a list of the most important endpoints:

  • /posts — Get posts.
  • /authors — Get authors.
  • /tags — Get tags.
  • /pages — Get pages.
  • /settings — Get settings.

Responses of these endpoints are lists that contain objects. Here is a sample response of the /posts endpoint:

{
  "posts": [
    {
      "slug": "welcome-short",
      "id": "5c7ece47da174000c0c5c6d7",
      "uuid": "3a033ce7-9e2d-4b3b-a9ef-76887efacc7f",
      "title": "Welcome",
      "html": "<p>👋 Welcome, it's great to have you here.</p>",
      "comment_id": "5c7ece47da174000c0c5c6d7",
      "feature_image": "https://casper.ghost.org/v2.0.0/images/welcome-to-ghost.jpg",
      "featured": false,
      "meta_title": null,
      "meta_description": null,
      "created_at": "2019-03-05T19:30:15.000+00:00",
      "updated_at": "2019-03-26T19:45:31.000+00:00",
      "published_at": "2012-11-27T15:30:00.000+00:00",
      "custom_excerpt": "Welcome, it's great to have you here.",
      "codeinjection_head": null,
      "codeinjection_foot": null,
      "og_image": null,
      "og_title": null,
      "og_description": null,
      "twitter_image": null,
      "twitter_title": null,
      "twitter_description": null,
      "custom_template": null,
      "canonical_url": null,
      "page": false,
      "primary_author": null,
      "primary_tag": null,
      "url": "https://demo.ghost.io/welcome-short/",
      "excerpt": "Welcome, it's great to have you here."
    }
  ]
}

response.json

The SDK also lets you define the specific fields you want to query and other filter options.

If you want more information about the Ghost Content API, I would recommend the official documentation.

Creating the Nuxt Project

Now that you have Ghost set up property and know the basics about the API, let’s start diving into your Nuxt.js front end.

Setup

First, you need to create a new Nuxt.js project and install the needed dependencies using the following commands:

npx create-nuxt-app nuxt-ghost 
cd nuxt-ghost && npm install @tryghost/content-api --save

These commands will create a basic Nuxt project and install the needed dependency. Now, you only need to create the needed files and folders before you can start coding.

Here is a screenshot of my folder structure:

Implementing the Ghost API

Now that you have completed the set-up process, you can go ahead and start implementing the actual functionality. Let’s start by copying your API key into the constant.js file you created above.

export const API_KEY = "YOUR-KEY"

The next step is to implement some utilities that will make using the Ghost Content API library a lot easier. For that, you need to add some simple code to your ghost.js file.

import GhostContentAPI from '@tryghost/content-api'
import {
  API_KEY
} from "../config/constants";

const ghost = (url, key) => {
  return new GhostContentAPI({
    url: url,
    key: key,
    version: 'v2'
  })
}

const postIndexFields = [
  'id',
  'uuid',
  'title',
  'slug',
  'feature_image',
  'published_at',
  'html',
  'excerpt'
]

const postsPerPage = 8

const ghostAPI = () => {
  return ghost("http://localhost:2368", API_KEY)
}

export {
  ghostAPI,
  postsPerPage,
  postIndexFields
}

ghost.js

All right, let’s walk through it for a better understanding:

  • We import the GhostContentAPI and API key from our configuration file.
  • Then, we create a basic Ghost API instance using the URL your Ghost instance runs on, and the API key of your API.
  • The postIndexFields variable defines the fields we want to get from the API and will be used later.
  • Lastly, we export the three variables so we can use them in other files.

Now open the pages/index.vue file and import the utilities you just created in your config.

<script>
import { ghostAPI, postIndexFields } from "@/utils/ghost";
export default {
  async asyncData() {
    const posts = await ghostAPI().posts.browse({
      fields: postIndexFields
    });
    const post = posts[0];
    return {
      post
    };
  }
};
</script>

index.vue

Here, you get all post you have published in Ghost and save them in a variable by defining the endpoint you want to send the request to (in this case, posts) and define the fields that you want to get (if you don’t define the fields, you will get all by standard).

Then, you return the first article of the array which you will display in your layout.

All you need to do now is render the markup and add some style.

  <section>
    <section class="blog-post">
      <h1 class="title">{{ post.title }}</h1>
      <div v-html="post.html"></div>
    </section>
  </section>
</template>

<script>
import { ghostAPI, postIndexFields } from "@/utils/ghost";
export default {
  async asyncData() {
    const posts = await ghostAPI().posts.browse({
      fields: postIndexFields
    });
    const post = posts[0];
    return {
      post
    };
  }
};
</script>

<style scoped>
.blog-post {
  margin: 25px 0;
  align-content: center;
  width: 100%;
  display: flex;
  justify-content: center;
  flex-direction: column;
  align-items: center;
}
.title {
  margin: 50px 0;
}
p {
  color: #000;
  margin: 15px 0 5px;
  max-width: 450px;
  line-height: 1.44;
}
</style>

index.vue

There you go. You’ve successfully fetched a blog post from the Ghost API.

If you open your app, it will look something like this:

This is image title

Voilà! You have a modern server-side rendered blog, built with Ghost.

We’ve barely scratched the surface of what is possible with the Ghost API but got a great overview of how to use it. The other requests function very similarly and can be added with a very small time investment.

The whole code of this tutorial is also available on my GitHub.

Conclusion

You made it all the way to the end! I hope that this article helped you understand the basics of Ghost and how you can use the API to build custom applications.

What is ECMAScript and How is it Different From JavaScript?

Many times developers use JavaScript and ECMAScript synonymously for each other. Though they are very closely linked to each other, it does not mean they are the same thing.here is a complete story on the history of JavaScript and how it came into existence. To cut the long story short, ECMA in ECMAScript refers to Europen Computer Manufacturers Association to which JavaScript 1.1 was submitted for standardization back in the year 1997.

Data Types In JavaScript

JavaScript data types are kept easy. While JavaScript data types are mostly similar to other programming languages; some of its data types can be unique. Here, we’ll outline the data types of JavaScript.
