change directory to the newly created angular application

cd buttercms-angular-nine

Install Angular Material and Angular Material related packages

npm install --save @angular/material @angular/cdk
npm install -S @angular/flex-layout

Install ButterCMS npm i -S buttercms The source code is available on Github

Quickstart

Open the project in your code editor of choice.

Under src/app create a directory called services

We create a file called butterCMS.service.ts. This allows us to have our API Token in one place and not accidentally alter it.

import Butter from 'buttercms';

export const butterService = Butter('your_api_token');

We'll import this file into any component we want to use ButterCMS.

For a Quickstart create a component in angular to load the sample headlines and posts from buttercms

from your buttercms-angular-nine directory type:

ng g c hello-you -s true -t true --skipTests

This will create a component called hello-you with inline-style and inline-template with no spec file. angular cli will also include this component in your app.module.ts

import {butterService} from '../services';

Inside HelloYouComponent create methods:

    private fetchPosts() {
        butterService.post.list({
                page: 1,
                page_size: 10
            })
            .then((res) => {
                console.log('Content from ButterCMS');
                console.log(res);
                this.posts = res.data;
            });
    }

Now call this method when the component is loaded by adding it to the OnInit lifecycle hook:

    ngOnInit() {
      this.fetchPosts();
    }

This API request fetches our blog posts. Your account comes with one example post which you'll see in the response.

Next, create another method to retrieve the Homepage Headline Content Field:

    private fetchHeadline() {
        butterService.content.retrieve(['homepage_headline'])
            .then((res) => {
                console.log('Headline from ButterCMS');
                console.log(res);
                this.headlines = res.data;
            });
    }

Add this method to the OnInit lifecycle hook.

    ngOnInit() {
        this.fetchPosts();
        this.fetchHeadline();
    }

This API request fetches homepage headline content. You can setup your own custom content fields to manage any content kind of content you need.

Hook this component up in Angular by adding ` to app.component.html and see it in action!

Pages

Integrate your app

With our page defined, the ButterCMS API will return it in JSON format like this:

{
    "data": {
        "slug": "acme-co",
        "fields": {
            "facebook_open_graph_title": "Acme Co loves ButterCMS",
            "seo_title": "Acme Co Customer Case Study",
            "headline": "Acme Co saved 200% on Anvil costs with ButterCMS",
            "testimonial": "<p>We've been able to make anvils faster than ever before! - <em>Chief Anvil Maker</em></p>\r\n<p><img src=\"https://cdn.buttercms.com/NiA3IIP3Ssurz5eNJ15a\" alt=\"\" caption=\"false\" width=\"249\" height=\"249\" /></p>",
            "customer_logo": "https://cdn.buttercms.com/c8oSTGcwQDC5I58km5WV",
        }
    }
}

Here's how the whole hello-you.component.ts will look like:

import {Component, OnInit} from '@angular/core';

import {butterService} from '../services';

@Component({
    selector: 'app-hello-you',
    template: `
        <h1>Hello-You</h1>
        <p>
            Headline:
            {{headlines?.data?.homepage_headline}}
        </p>
        <p>
            Sample Post:
            {{posts? posts.data[0]?.url : 'no posts'}}
        </p>
    `,
    styles: []
})
export class HelloYouComponent implements OnInit {

    posts;
    headlines;

    constructor() {
    }

    ngOnInit() {
        this.fetchPosts();
        this.fetchHeadline();
    }

    private fetchHeadline() {
        butterService.content.retrieve(['homepage_headline'])
            .then((res) => {
                console.log('Headline from ButterCMS');
                console.log(res);
                this.headlines = res.data;
            });
    }

    private fetchPosts() {
        butterService.post.list({
                page: 1,
                page_size: 10
            })
            .then((res) => {
                console.log('Content from ButterCMS');
                console.log(res);
                this.posts = res.data;
            });
    }
}

This guide uses the Angular framework and Angular cli to generate all our components and package our application. We are using Angular Material for our look and feel, but feel free to use any other.

Let's get to the code.

Now we will build on top of what we have created so far.

In a terminal run

ng serve

Your localhost:4200 should be ready to serve your Angular page.

Under src/app look at the file called app-routing.module.ts

Initially it looks like this :

 import { NgModule } from '@angular/core';
 import { Routes, RouterModule } from '@angular/router';
 
 const routes: Routes = [];
 
 @NgModule({
   imports: [RouterModule.forRoot(routes)],
   exports: [RouterModule]
 })
 export class AppRoutingModule { }

Update the routes in your app to route to the specified components.

These components are generated by angular cli using ng g c <my-new-component> Here are 8 components we will need to create:

ng g c blog-post-details --skipTests 
ng g c blog-post-listing --skipTests 
ng g c customer-details --skipTests 
ng g c customer-listing --skipTests 
ng g c faq --skipTests
ng g c feed --skipTests 
ng g c home --skipTests
ng g c topav --skipTests

You will also need a shared folder that contains a list of Angular Material modules and a model folder, that will contain our topNav models.

Since we are using Angular Material, you will need to provide a themes folder that contains what theme we want to use for Angular Material.

Here is how your app-routing.module.ts should look like:

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';
import {FaqComponent} from './faq/faq.component';
import {HomeComponent} from './home/home.component';
import {FeedComponent} from './feed/feed.component';
import {HelloYouComponent} from './hello-you/hello-you.component';
import {BlogPostListingComponent} from './blog-post-listing/blog-post-listing.component';
import {CustomerListingComponent} from './customer-listing/customer-listing.component';
import {CustomerDetailsComponent} from './customer-details/customer-details.component';
import {BlogPostDetailsComponent} from './blog-post-details/blog-post-details.component';

const appRoutes: Routes = [
    {path: 'customer', component: CustomerListingComponent},
    {path: 'customer/:slug', component: CustomerDetailsComponent},
    {path: 'faq', component: FaqComponent},
    {path: 'blog', component: BlogPostListingComponent},
    {path: 'blog/:slug', component: BlogPostDetailsComponent},
    {path: 'rss', component: FeedComponent},
    {path: 'hello-you', component: HelloYouComponent},
    {path: 'home', component: HomeComponent},
    {path: '**', redirectTo: 'home'}
];

@NgModule({
    imports: [RouterModule.forRoot(appRoutes)],
    exports: [RouterModule]
})
export class AppRoutingModule {
}

Setup the Customers Page to list all our customers.

We've already created all the components we need so far.

In Customer listing page, we should

Import butterService
In OnInit hook, use butterService to get the list of customers
Store results in pages variable and markup (html) will be updated with the data

import {Component, OnInit} from '@angular/core';
import {butterService} from '../services';

@Component({
    selector: 'app-customer',
    templateUrl: './customer-listing.component.html',
    styleUrls: ['./customer-listing.component.scss']
})
export class CustomerListingComponent implements OnInit {

    public pages: any[];

    constructor() {
    }

    ngOnInit() {
        butterService.page.list('customer_case_study')
            .then((res) => {
                this.pages = res.data.data;
            });
    }
}

Display the results in customer-listing.component.html

<mat-card>
    <mat-card-title class="page-title">Customers</mat-card-title>
    <mat-divider></mat-divider>
    <mat-card-content class="page-body">
        <mat-card *ngFor="let page of pages">
            <mat-card-title>
                <div class="container">
                    <a [routerLink]="[page.slug]">
                        <div fxLayout="row" fxLayout.xs="column"
                             fxFlex class="content">
                            <div class="blocks">
                                <img src="{{page.fields.customer_logo}}" alt="{{page.fields.seotitle}}" height="64"
                                     width="64"/>
                            </div>
                            <div class="blocks">
                                {{page.fields.headline}}
                            </div>
                        </div>
                    </a>
                </div>
            </mat-card-title>
        </mat-card>
    </mat-card-content>
    <mat-divider></mat-divider>
    <mat-card-footer>
        <div class="page-footer">
            <mat-icon>whatshot</mat-icon>
        </div>
    </mat-card-footer>
</mat-card>

Setup the Customer Page to view single page

In the customer details component

Create customer page

Import butterService
In OnInit hook, use butterService to get the customer page given the slug in the URL path
Store results in page variable and markup (html) will be updated with the customer data

import {Component, OnInit} from '@angular/core';
import {Observable} from 'rxjs';
import {ActivatedRoute} from '@angular/router';
import {butterService} from '../services';
import {map, take} from 'rxjs/operators';


@Component({
    selector: 'app-customer-details',
    templateUrl: './customer-details.component.html',
    styleUrls: ['./customer-details.component.scss']
})
export class CustomerDetailsComponent implements OnInit {

    public page: any;
    protected slug$: Observable<string>;

    constructor(protected route: ActivatedRoute) {
    }

    ngOnInit() {
        this.slug$ = this.route.paramMap
            .pipe(
                map(params => (params.get('slug')))
            );

        this.slug$.pipe(
            take(1))
            .subscribe(slug => {
                butterService.page.retrieve('customer_case_study', slug)
                    .then((res) => {
                        this.page = res.data.data;
                    }).catch((res) => {
                    console.log(res);
                });
            });
    }
}

Display the result in customer-details.component.html

<mat-card>
    <div class="container">
        <div fxLayout="column" class="details">
            <div class="blocks">
                <img src="{{page?.fields?.customer_logo}}" alt="" height="124" width="124"/>
            </div>

            <h1 class="blocks">
                {{page?.fields?.headline}}
            </h1>
            <h3 class="is-size-3">Testimonials</h3>
            <div [innerHTML]="page?.fields?.testimonial"></div>
            <div [innerHTML]="page?.fields?.body"></div>
        </div>
    </div>
</mat-card>

We can now navigate to the Customer Page via the list of all Customer Pages or directly via url.

Content Fields

Integrate with your app

Create FAQ Component

In the faq component we need to setup the onInit hook.

Setup onInit hook to load FAQ

import {Component, OnInit} from '@angular/core';
import {butterService} from '../services';

@Component({
    selector: 'app-faq',
    templateUrl: './faq.component.html',
    styleUrls: ['./faq.component.scss']
})
export class FaqComponent implements OnInit {

    constructor() {
    }

    public faq: any = {
        items: [],
        title: 'FAQ'
    };

    ngOnInit() {
        butterService.content.retrieve(['faq_headline', 'faq_items'])
            .then((res) => {
                console.log(res.data.data);
                this.faq.title = res.data.data.faq_headline;
                this.faq.items = res.data.data.faq_items;
            });
    }
}

Display the result

<mat-card>
    <mat-card-title class="page-title">{{faq.title}}</mat-card-title>
    <mat-divider></mat-divider>
    <mat-card-content class="page-body">
        <mat-card *ngFor="let item of faq.items">
            <mat-card-content>
                <h3>
                    {{item.question}}
                </h3>
                <div>
                    {{item.answer}}
                </div>
            </mat-card-content>
        </mat-card>
    </mat-card-content>
    <mat-divider></mat-divider>
    <mat-card-footer>
        <div class="page-footer">
            <mat-icon>whatshot</mat-icon>
        </div>
    </mat-card-footer>
</mat-card>

That's it! The values entered in the Butter dashboard will immediately update the content in our app.

Blog Engine

To display posts we create a simple /blog route in our app and fetch blog posts from the Butter API, as well as a /blog/:slug route to handle individual posts.

See our API reference for additional options such as filtering by category or author. The response also includes some metadata we'll use for pagination.

Setup the Blog page to list all our posts.

In the blog-post-listing component, import butterService and load all posts using the onInit hook.

Update component to get all posts

import butterService
Get all post onInit

import {Component, OnInit} from '@angular/core';
import {butterService} from '../services';

@Component({
    selector: 'app-blog-post-listing',
    templateUrl: './blog-post-listing.component.html',
    styleUrls: ['./blog-post-listing.component.scss']
})
export class BlogPostListingComponent implements OnInit {
    public posts: any[];

    constructor() {
    }

    ngOnInit() {
        butterService.post.list({
            page: 1,
            page_size: 10
        }).then((res) => {
            this.posts = res.data.data;
        });
    }
}

Display the result

Setup the Blog Post page to list a single post.

blog-post-details will show a single post.

apps/blog-post-details.component.ts

To show to the single post

Import butterService
In OnInit hook, use butterService to get the blog-post post given the slug in the URL path
Store results in post variable and markup (html) will be updated with the customer data

import {Component, OnInit, ViewEncapsulation} from '@angular/core';
import {Observable} from 'rxjs';
import {ActivatedRoute} from '@angular/router';
import {butterService} from '../services';
import {map, take} from 'rxjs/operators';

                        this.post = res.data;
                    }).catch((res) => {
                    console.log(res);
                });
            });
    }
}

Display the results

            </div>
        </div>
    </div>
</mat-card>

Now our app is pulling all blog posts and we can navigate to individual posts.

However, our next/previous post buttons are not working. You should try showing the next/previous posts after this tutorial.

Now our app has a working blog that can be updated easily in the ButterCMS dashboard.

Categories, Tags, and Authors

Use Butter's APIs for categories, tags, and authors to feature and filter content on your blog:

List all categories and get posts by category

Call these methods on the onInit() lifecycle hook

methods: {
  ...
  getCategories() {
    butter.category.list()
      .then((res) => {
        console.log('List of Categories:')
        console.log(res.data.data)
      })
  },
  getPostsByCategory() {
    butter.category.retrieve('example-category', {
        include: 'recent_posts'
      })
      .then((res) => {
        console.log('Posts with specific category:')
        console.log(res)
      })
  }
},
created() {
  ...
  this.getCategories()
  this.getPostsByCategory()
}

RSS, Atom, and Sitemap

Butter generates RSS, Atom, and sitemap XML markup. To use these on your blog, return the generated XML from the Butter API with the proper content type headers.

Create a file to see an example of what we get back from the API.

app/feed/feed.component.ts

import {Component, OnInit} from '@angular/core';
import {butterService} from '../services';

@Component({
    selector: 'app-misc',
    templateUrl: './feed.component.html',
    styleUrls: ['./feed.component.scss']
})
export class FeedComponent implements OnInit {
    protected rss;
    protected atom;
    protected sitemap;

    constructor() {
    }

    ngOnInit() {
        butterService.feed.retrieve('rss').then((res) => {
            console.log(res.data.data);
            this.rss = res.data.data;
        });

        butterService.feed.retrieve('atom').then((res) => {
            console.log(res.data.data);
            this.atom = res.data.data;
        });

        butterService.feed.retrieve('sitemap').then((res) => {
            console.log(res.data.data);
            this.sitemap = res.data.data;
        });
    }
}

to display the result we get from butterService

    <mat-card-title class="page-title">RSS, Atom & Sitemap</mat-card-title>
    <mat-divider></mat-divider>
    <div class="feeds">

        </div>
    </mat-card-footer>
</mat-card>

Navigate to localhost:4200/rss

We can see ButterCMS passes back the entire xml need to create a feed or sitemap. However, this demo page will not work for our subscribers. We need to create xml files they can link to in their RSS readers.

This can be a challenge for a static deployed site built using Angular that has dynamic content.

Fortunately ButterCMS has Webhooks that we can utilizing to POST change notifications.

Setup to create feeds and sitemap

Setup up a listener webhook on your hosting that will trigger a rebuild or redeploy of your static site when it receives a POST request.

Setup a POST Webhook in the ButterCMS dashboard with the Event "Blog Post Create, Update, or Delete" and paste the listener url into Target URL field.
