This starter is based on the official blog-starter-typescript from Next.js.

We changed it only enough to make it possible to fetch and publish blog posts from the Ghost CMS, while keeping the ability to write Markdown files in the git repo. It's a purely additive change.

There's also a GitHub Action to build and publish the static website to Fission. It works automatically on pushes to the git repo, and can be triggered manually after updating the content on Ghost. (The default Ghost webhook isn't customizable to trigger a GitHub Action, but that can be added as a plugin.)

The Markdown blog posts are stored in /_posts as files with frontmatter support. Adding a new Markdown file in there will create a new blog post.

The Ghost blog posts are fetched using Ghost's Content API library.

✨  Getting Started

Let's start by making this starter yours:

• Click Use this template at the starter page on GitHub

  That will make a copy of the starter into a new repo under your account with a fresh git history. You can pick a different name for it too; in that case replace nextjs-blog-starter-typescript-ghost with your chosen name below.

• Clone the repo (replace with your own URL):

  git clone git@github.com:fission-suite/nextjs-blog-starter-typescript-ghost.git
  

• cd into the repo:

  cd nextjs-blog-starter-typescript-ghost
  

• Install dependencies

  yarn
  

All command-line instructions and directory paths from now on assume the current directory is the root of the cloned repo.

👻  Setting Up Ghost

Cloud or Local Ghost?

Running a local Ghost instance is good for testing. But also, if you have no need for a Ghost instance running all the time out on the internet (for example, if you are the only author) you can do this for your production website, using Ghost locally for its nice interface if you prefer that to editing Markdown files. No servers to secure, no bills to pay.

Setting Up Local Ghost

If you have a Ghost instance running already somewhere, move on to the next step. If you don't, you can set one up on your own machine with Docker.

To create a local Ghost instance with Docker, run the following at the root of your repo:

yarn ghost-local-create

Ghost data will be stored at ./ghost, which is in .gitignore by default. In a private repo you can choose to commit that too and have your Ghost content versioned and available whenever you need it.

There are other scripts like ghost-local-start, ghost-local-stop, and ghost-local-remove which you might find handy to manage the Docker container.

After Docker downloads and sets up Ghost, it will be accessible on your browser at http://localhost:3001.

Next you need to create an admin account on your newly-created Ghost. To do that, visit the admin interface at http://localhost:3001/ghost and follow the wizard.

Setting Up Cloud Ghost

You can deploy a Ghost instance to Heroku using Fission's own starter (it's what we use for our blog) at https://github.com/fission-suite/heroku-ipfs-ghost.

Besides being a very low-friction and zero-cost way to get started with Ghost, our starter comes with built-in support for hosting media files on IPFS via Fission, no extra configuration required.

Exposing the Ghost Content API

I'll use http://localhost:3001 for the examples, but you can replace that with your Ghost URL if you have an instance already running somewhere else.

• Go to the admin interface at http://localhost:3001/ghost
• On the left-hand sidebar, click on "Integrations"
• On the Integrations screen, click on +Add custom integration
• Give it a name, like nextjs, and click "Create" then "Save"

Now the important part:

• On the same screen, you'll find two fields we need: Content API Key and API URL
• Copy those into a new .env.local file, like this:

# .env.local
# replace values with your own
GHOST_API_URL=http://localhost:3001
GHOST_API_KEY=2a9356e4a5214c883ba886e58e

⚠️ This file is ignored by git by default. Don't commit env.local to git unless you know what you're doing.

Alright! Ghost part's done.

💻  Running Next.js Locally

Next.js is the missing static website head to our headless Ghost. Let's stitch them together! This should be enough:

yarn dev

Your blog should be up and running at http://localhost:3000! (If anything unexpected happens, please post an issue.)

Now you can change the Next.js website code and the content on Ghost, and iterate quickly on them in the browser.

Note: live-reload works for Next.js code and Markdown files; to see changes to Ghost content you need to refresh the page.

🌐  Deploying to Fission

When you're ready to publish, the first step is exporting your website to a set of static files:

yarn build

That should create a directory at ./out with all your ready-to-publish files.

Next we use the Fission CLI to send that out onto the internets.

🔰  Fission CLI Install and Sign Up

To install the Fission command-line interface using brew, run:

brew tap fission-suite/fission
brew install fission-cli

For more ways of installing the Fission CLI, please check the documentation.

If you don't have a Fission account, you can create one without leaving the command-line by running:

fission setup

🌱  Register New Fission App

You can pick a subdomain or let Fission choose a random one for you.

To host the Next.js website at a random subdomain on .fission.app, run:

fission app register

To choose your own subdomain, use the --name option like this:

fission app register --name my-beautiful-subdomain

That will create a fission.yaml file. This one is safe to commit to git, and you should do that if you want to use the GitHub Action to build and deploy the website for you. Make sure there is a line saying build: ./out in it. That's the directory where Next.js puts the exported website files.

🚀   Aand... Launch!

One last step:

fission app publish

And you're done! Your website should be up at a random URL returned to you by the Fission CLI or at my-beautiful-subdomain.fission.app if you used the --name option. Yay!

🤖  (Semi-)Automatic Deployment with the GitHub Action

If you don't want to run the build locally and deploy to Fission every time you make a change to the Next.js code or Markdown files (who does?), this starter comes with a GitHub Action that automates that for you.

To get it working you need to set up 3 secrets for your repo. To do that, go to the "Settings" > "Secrets" screen on your GitHub repo, then create a "New repository secret" for each of these:

• GHOST_API_URL
• GHOST_API_KEY
• FISSION_KEY

The values for the GHOST_API_ fields are the same ones you used for the .env.local file above.

The FISSION_KEY was created and stored locally for you by the Fission CLI when you set it up. Here's how you get it:

cat ~/.config/fission/key/machine_id.ed25519 | base64

With all 3 secrets set up, you can trigger the deploy action manually by clicking on "Run workflow" > "Run workflow", or see it in action after your next git push.

---

Note:

⚠️  To fetch the content from Ghost, the GitHub Action must be able to access the URL entered in the GHOST_API_URL secret.

If you are running a local Ghost instance on your machine, http://localhost:3001 won't be visible to the outside.

A simple way of exposing your local Ghost instance to a publicly-reachable URL is by using one of the open source alternatives to ngrok or ngrok itself.

With ngrok you do something like this:

ngrok http 3001

⚠️  This is great for testing, but not secure. Look into using https if you're going to rely on this and don't want your Ghost API key and data to leak.

---

Why "(semi-)" automatic then? 🤔

Glad you asked. The GitHub Action can detect when you push to the GitHub repo because there's a built-in "on push" event that can be used to trigger it.

But when you create a new post on Ghost or update an existing one, GitHub needs a way of finding out about it so it can run the deploy action. There's no git push event happening, so the trigger is usually a webhook (i.e. a POST request you send to a GitHub API URL.)

🙂  Luckily, Ghost comes with the built-in ability to send webhooks when content changes happen.

🙃  Unluckily, though, Ghost doesn't let you customize the payload that goes in the webhook requests it sends, and GitHub requires a certain field to be present telling it which ref (usually a branch) you are referring to.

Bottom line: after changing things on Ghost, you need to trigger a build manually.

You can do that via the GitHub interface ("Actions" > "Continuous Deployment" > "Run workflow" > "Run workflow"), or by running the handy script we added to this starter:

GITHUB_USER=your-username GITHUB_REPO=your-repo GITHUB_AUTH_TOKEN=your-auth-token trigger-github-deploy-action.sh

Here's how you can get an auth token.

This situation is definitely not ideal, and can be solved with Ghost plugins, but we wanted to stick to the basic install.
