We'll be building a blog site with the Angular framework, Scully for static site generation(SSG) and then deploying the project on Netlify so that it can be accessible to the public.

What this article covers

• Using Angular to build the blog architecture
• Installing Scully library to handle static site Generation
• Netlify deployment
• Demo of this project
• Repository for the demo

Setup requirements

We'll be using the following tools for this project

• Angular v13
• Tailwind
• Scully
• Node v14.15 (or higher)

Angular is an application design framework and development platform for creating efficient and sophisticated single-page apps. It's an opensource frontend framework built by Google.

Scully is a library used for generating static sites built with Angular and ushers you into the jamstack. SSGs generate static pages when you build your project so that what you publish/deploy is the already built pages which can be indexed by google(for some of that SEO good good) and served quickly to clients. Without scully, our angular project will go through client side rendering where each page of the application that is visited is rendered by the browser at runtime.

Tailwind is a CSS utility library that is used to speed up the styling of applications by offering flexibility and conciseness.

Now that we have some background on the project, we can start building

Generating the Angular project

Use the command below to generate a new angular project. You can name your project what you like. I have chosen angular-blog

ng new angular-blog

You'll see the following questions. We want routing and SCSS stylesheet format.

? Would you like to add Angular routing? Yes
? Which stylesheet format would you like to use? SCSS 

After the project has been generated, serve the application using the ng serve command

ng serve

You'll be greeted with the standard angular welcome template.

Navigate to app.component.html and delete the entire content (we don't want that welcome page showing up) and then place <router-outlet></router-outlet> tags since this is where all our modules and components will be displayed based on the route configuration in app.routing-module.ts

Installing Scully

Run the command below to install scully and automatically make all the necessary configurations to the project

ng add @scullyio/init

During the installation, you'll get the question below. As at the time of this writing, pupeteer is the most stable renderer so we'll choose that.

? Which route renderer would you like to use?
  Scully platform server
> Puppeteer
  Playwright (beta)

Here is what the terminal looks like after the installation process

The init schematic of the scully installation made a couple of changes which include;

• installing the pupeteer plugin
• updating the app.module.ts by importing the ScullyLibModule
• updating the package.json file with scully commands for building and serving the generated pages

    "scully": "npx scully --",
    "scully:serve": "npx scully serve --"

• created a scully.angular-blog.config.ts file which is the scully configuration file.

Adding blog support to our project

Scully has a schematic for creating the blog section for our project

ng generate @scullyio/init:blog

This adds a lazy-loaded blog module's routes to the Angular application(app.routing-module.ts) and creates a ./blog folder for the blog's markdown files(where our blog posts will live).
Below is the current route configuration in app.routing-module.ts updated by scully.

const routes: Routes = [{ path: 'blog', loadChildren: () => import('./blog/blog.module').then(m => m.BlogModule) }];

It also updates the scully.angular-blog.config.ts with the blog routes to prerender.

A few other configurations to do

Now we have a module for our blog feature. The next things we need to create are;

• a component for the list of blog posts using the command below

ng generate component blog/blog-list

• a component that will show the actual blog post content using the command below

ng generate component blog/blog-post

We also need to go to the blog.routing.module.ts and fix up our route configuration as below

const routes: Routes = [
  {
    path: '',
    component: BlogComponent,
    children: [
      {path: ':slug', component: BlogPostComponent},
      {path: '', component: BlogListComponent}
      ]
  }
];

Lastly, we add the <router-outlet></router-outlet> in the blog.component.html to handle routing in the module.This page will display the blog list and blog posts based on the route configuration in blog-routing.module.ts

Configuring the route entry point for scully

After sorting out the module for our blog feature, we need to create an entry point for scully (typically the home page of our app).

It is suitable to leverage the Angular lazy-loaded module feature for our app home page because this part of our app is separate from the blog part.
Create a home module with the following command:

ng generate module home --route=home --module=app-routing

This updates the route configuration in app-routing.module.ts with the path for the home module. Set its path to an empty string.

const routes: Routes = [{
        path: 'blog',
        loadChildren: () => import('./blog/blog.module').then(m => m.BlogModule)
    },
    {
        path: '',
        loadChildren: () => import('./home/home.module').then(m => m.HomeModule)
    },
    {path: '**', redirectTo: 'blog', pathMatch: 'full'},
];

You can always add a redirect below the route configuration for the blog module if you don't want the home page to be accessed yet.

{path:'',redirectTo:'blog',pathMatch:'full'},

Building the Angular-Scully app

After all those configurations, we need to build our project with Angular, build with Scully then serve the built project on the Scully server but first, let's restart the Angular server.

Build the project by running

ng build

Then we build with scully using

npx scully

We can also modify the build command in our package.json so that it will run the two previous commands.

"build": ng build && npm run scully -- --scanRoutes

Now we can use npm run build to achieve the same thing.
After those two commands, a dist folder is created in the root directory of our project. This folder contains the two built versions of our site, The folder named angular-blog is the one built by Angular while the one named static contains the static pages generated by scully.
Now, we can start the scully server using the command:

npx scully serve

After the server starts successfully, navigate to http://localhost:4200/blog to see the angular app running, then in a separate tab, open this link http://localhost:1668/blog to see the static site. You browser should show a white page with the text blog-list works!.

To check our actual blog post (created by the init:blog schematic) go to the markdown file in the blog folder and copy the value of the slugs property in the frontmatter.

---
title: "2022-04-29-blog"
description: 'blog description'
published: false
slugs:
    - ___UNPUBLISHED___l2kp8pyl_z4RfUZ7hSOMdOfldi8yqeZcOKuebIId2
---

That is the current path(generated by scully) to the blog post when published: false. It's a private route to your blog post when it's still in draft version so you can share with anyone to get an article review before publishing. When you are ready to publish the post, you can set published: true and remove the slugs property which will allow scully use the file name(without the extension) as its path when it generates the static pages.

Go to address bar of the tab serving the static site and paste the slug after http://localhost:1668/blog/ then press enter. You should see the content of the blog post.

Now, we have confirmed that our blog feature is fully functional so next up is to add more blog posts.

Creating blog posts

We can create a blog post with the command below. The name option takes the name of your post.

ng generate @scullyio/init:post --name="Post 1"

This creates a markdown file in the blog folder.
When we open the newly created markdown file, we see this

---
title: Post 1
description: blog description
published: false
---

# Post 1

As you now know, the content between the three dashes is the frontmatter and below the frontmatter is the blog content.

The frontmatter is where we can add information about the post such as metadata, SEO e.t.c.
Let's update this markdown file to look like this

---
title: Post 1
description: blog description
published: true
image: /assets/images/enigma.jpg
seo: {
metaDescription: First post for my angular scully blog,
metaTitle: First post
},
---

# Post 1

I have added an image in the corresponding directory which I'll render in post.
When we're satisfied with our markdown file, we can build with the npx scully command.

A tip on knowing which to build with

ng build is only needed when you modified something in your angular app. The scully config file, plugins, and eventual markdown files are not part of your Angular app. Although this may seem evident, if this is your first time using Scully it is easy to rebuild Angular even if it is not needed. When writing Scully plugins OR modifying your blog's markdown files, you DO NOT need to ng build the app each time you re-run Scully. Again, ng build Angular only if the Angular app changes

Showing all blog posts

Let's head over to blog-list.component.ts to work out the logic that handles data for the component.
In this component, we will inject the ScullyRoutesService as a dependency which will give us access to the blog posts routes.

import { Component, OnInit } from '@angular/core';
import {ScullyRoute, ScullyRoutesService} from "@scullyio/ng-lib";
import {Observable} from "rxjs";

@Component({
  selector: 'app-blog-list',
  templateUrl: './blog-list.component.html',
  styleUrls: ['./blog-list.component.scss']
})
export class BlogListComponent implements OnInit {
  links$: Observable<ScullyRoute[]> = this.scully.available$;

  constructor(private scully: ScullyRoutesService) { }

  ngOnInit(): void {
    this.getPublishedPosts();
  }

  getPublishedPosts() {
    this.links$ = this.links$.pipe(tap(val) => console.log(val))
  }
}

What we want to render are the published posts, that's why we get the published routes from the available$ property on the ScullyRoutesService.

In the blog-list.component.html we can build the template that shows all blog posts. We'll work with the code below for now.

<div>
  <ul>
    <li *ngFor="let post of links$ | async">
    <a [href]="post.route">{{post.title}}</a>
    </li>
  </ul>
</div>

After you save, you should see an array of two routes in the console. We can't see any blog posts route yet because we haven't built with scully after changing the published property to true.

Let's ensure that the published property in our markdown files are set to true then build with scully to update our published routes.
Now when we reload, we should see an array of 4 routes in the console. However, since we only want blog posts routes, we'll need to transform our data with some rxjs.
Let's update the getPublishedPosts function

getPublishedPosts() {
    this.links$ = this.links$.pipe(map((links) => links.filter((link) =>
      link.route.startsWith('/blog/'))),tap((val) => console.log(val)));
  }

To ensure the scully version of our site is updated, let's run the command:

npm run build

Now we should have our page like this.

You can click on the links to see that they show the corresponding posts.

Accessing the data in the blog post page

We can get the route data of a particular page we navigate to with the help of the ScullyRoutesService by subscribing to the observable returned by the getCurrent() method.
Add the code below to the blog-post.component.ts

import {Component, OnDestroy, OnInit} from '@angular/core';
import {ScullyRoute, ScullyRoutesService} from "@scullyio/ng-lib";
import {Subject, takeUntil} from "rxjs";
import {tap} from "rxjs/operators";

@Component({
  selector: 'app-blog-post',
  templateUrl: './blog-post.component.html',
  styleUrls: ['./blog-post.component.scss']
})
export class BlogPostComponent implements OnInit, OnDestroy {
  currentRoute: ScullyRoute = {} as ScullyRoute;
  onDestroy$ = new Subject<void>();

  constructor(private scully: ScullyRoutesService) {
  }

  ngOnInit(): void {
    this.getCurrentPost()
  }

  getCurrentPost() {
    this.scully.getCurrent()
      .pipe(takeUntil(this.onDestroy$))
      .subscribe((routeData: ScullyRoute) => {
        this.currentRoute = routeData;
      });
  }

  ngOnDestroy() {
    this.onDestroy$.next();
    this.onDestroy$.complete();
  }
}

Details of our current route is assigned to this.currentRoute property and this allows us use the route data for that particular post the way we want.

Styling our blog

Firstly, we need to create another component which will be our reusable component for the blog cards. Use the command:

ng generate component blog/blog-list/blog-card

Open the blog-card.component.html and place the code below inside it

<li *ngFor="let post of links$ | async">
    <a [href]="post.route">{{post.title}}</a>
</li>

Then we make use of this component in our blog-list.component.html via the app-blog-card selector in this way

<div>
  <ul>
    <app-blog-card [post]="post" *ngFor="let post of links$ | async"></app-blog-card>
  </ul>
</div>

We are also passing each route object in the array as post through the app-blog-card component therefore, we will need to receive this data from the parent component(blog list) in our child component (blog card) using the Input() decorator.
Let's do that by putting the code below in the blog-card.component.ts

import {Component, Input, OnInit} from '@angular/core';
import {ScullyRoute} from "@scullyio/ng-lib";

@Component({
  selector: 'app-blog-card',
  templateUrl: './blog-card.component.html',
  styleUrls: ['./blog-card.component.scss']
})
export class BlogCardComponent implements OnInit {
  @Input() post: Partial<ScullyRoute> = {};

  constructor() { }

  ngOnInit(): void {
  }
}

Finally, some styling

You can use any styling format you want. I'll be using tailwind.
Let's use the straightforward tailwind documentation to configure it in our project.
After the configuration is done, we'll need to restart the angular server.
Update the blog-card.component.html with the new template below

<li class="h-full">
  <a [href]="post.route" class="h-full w-full lg:max-w-full lg:flex hover:bg-gray-100">
    <div
      class="h-48 lg:h-auto lg:w-48 flex-none bg-cover rounded-t lg:rounded-t-none lg:rounded-l text-center overflow-hidden"
      [style.background-image]="'url(' + (post['image'] || 'https://images.unsplash.com/photo-1496494118863-9cf5d1e70cd6?ixlib=rb-1.2.1&ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&auto=format&fit=crop&w=870&q=80') + ')'"
      title="Mountain">
    </div>
    <div
      class="w-full border-r border-b border-l border-gray-400 lg:border-l-0 lg:border-t lg:border-gray-400  rounded-b lg:rounded-b-none lg:rounded-r p-4 flex flex-col justify-between leading-normal">
      <div class="mb-8">
        <div class="text-gray-900 font-bold text-xl mb-2">{{post.title}}</div>
        <p class="text-gray-700 text-base">{{post['seo']?.metaDescription || post['description']}}</p>
      </div>
    </div>
  </a>
</li>

Also update the blog-list.component.html

<div>
  <ul class="p-10 grid grid-cols-1 sm:grid-cols-1 md:grid-cols-1 lg:grid-cols-1 xl:grid-cols-3 gap-5">
    <app-blog-card [post]="post" *ngFor="let post of links$ | async"></app-blog-card>
  </ul>
</div>

The code below adds a header to our site. Add it in app.component.html

<nav class="flex flex-wrap items-center justify-between bg-gray-800 p-6 w-full">
  <div>
    <a class="text-white no-underline hover:text-white hover:no-underline" routerLink="/">
      <span class="text-2xl">Angular scully blog</span>
    </a>
  </div>
  <ul class="list-reset flex justify-end flex-1 items-center">
    <li class="mr-3">
      <a class="inline-block text-white no-underline hover:text-gray-200 hover:text-underline py-2 px-4"
         routerLinkActive="" routerLink="/blog">blog</a>
    </li>
  </ul>
</nav>
<router-outlet></router-outlet>

Now we have a nice user interface that shows all blog post

Let's add the code below for the blog post user interface(blog-post.component.html)

<main class="mx-auto max-w-screen-sm max-w-screen-lg">
  <img [src]="currentRoute['image'] || 'https://cdn.mos.cms.futurecdn.net/4uiRZ5nNAgpHSifSjaKwcC-970-80.jpg.webp'"
       alt="nft"/>
  <h3>ScullyIo content</h3>
  <hr>

  <!-- This is where Scully will inject the static HTML -->
  <scully-content></scully-content>
  <hr>
  <h4>End of content</h4>
</main>

Finally, use the npm run build command to build the project and checkout the scully static version in your browser.

Pushing to Github

Create a repository on Github and then copy the remote url (https://github.com/<github-username>/<repository-name>.git) so that we can add it for our project using the command below:

git remote add origin https://github.com/<github-username>/<repository-name>.git

Rename the branch to main with the command below:

git branch -M main

Push to github with the command below:

git push origin main

Here's a link to the repository for this article demo.

npm install

npm run build

ng serve

npx scully serve

Deploying to Netlify

After pushing our Angular Scully blog to github, we are ready to deploy on Netlify. If you do not have an account yet, you can signup here or go ahead and log in to your account if you have one.

Choose import from git

Select Github

Connect the repository you want to deploy. You may need to configure netlify for your github account if it has not been setup. This is needed for netlify to have access to the repository

Provide the path to the folder where the scully generated static pages are as well as the build command


Click the Deploy site button and watch as netlify builds your project.
Congratulations on making it to the end and have fun personalising your site as you like.

Here's a link to the deployed site
