AstroJS: Integrate Dev.to content easily

Start a new project with the blog template

npm create astro@latest -- --template blog

We launch the app

cd [project_name] && npm run dev

Starting with Astro 5, the Content Layer API has been introduced, a tool that allows you to load data from any source during the construction of your site and access it through a simple, securely typed API.

This API offers flexibility to handle content from various sources, such as local Markdown files, remote APIs, or content management systems (CMS). By defining “collections” of content with specific schemas, you can structure and validate your data efficiently. Additionally, the Content Layer API improves performance on content-heavy sites, speeding up build times and reducing memory usage.

Astro's Content Layer API to integrate dev.to posts into your site

You can use Astro's Content Layer API to integrate dev.to posts into your site. Although there is no specific loader for dev.to, you can create a custom one that consumes its API and stores posts in a content collection in Astro.

To achieve this, follow these steps:

1. Configure access to the dev.to API

Create the .env file in the root of the project
.env

DEV_TO_API_URL=https://dev.to/api/
DEV_API_KEY=tu_clave_de_api

2. Define a collection in Astro

In src/content.config.ts, define a collection for dev.to posts using the Content Layer API:

When creating the project with the Astro template, it automatically generates the collection for the Blog

srccontent.config.ts

import { glob } from 'astro/loaders';
import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
    // Load Markdown and MDX files in the `src/content/blog/` directory.
    loader: glob({ base: './src/content/blog', pattern: '**/*.{md,mdx}' }),
    // Type-check frontmatter using a schema
    schema: z.object({
        title: z.string(),
        description: z.string(),
        // Transform string to Date object
        pubDate: z.coerce.date(),
        updatedDate: z.coerce.date().optional(),
        heroImage: z.string().optional(),
    }),
});

export const collections = { blog };

Now we create the collection for the Dev.to articles

const devTo = defineCollection({
    loader: async () => {
        const headers = new Headers({
            "api-key": DEV_API_KEY,
        });
        const posts = await fetch(`${DEV_TO_API_URL}articles?username=jmr85`, {
            headers: headers
        }).then(res => res.json());

        return posts.map((post: any) => ({
        id: post.slug,
            title: post.title,
            description: post.description,
            pubDate: new Date(post.published_at),
            updatedDate: post.edited_at ? new Date(post.edited_at) : null,
            heroImage: post.cover_image || post.social_image,
        url: post.url,
        }));
    },
    schema: z.object({
        title: z.string(),
        description: z.string(),
        pubDate: z.coerce.date(),
        updatedDate: z.coerce.date().optional(),
        heroImage: z.string().nullable(),
    url: z.string(),
    }),
  });

export const collections = { blog, devTo };

This is the complete code for
srccontent.config.ts

DEV_TO_API_URL=https://dev.to/api/
DEV_API_KEY=tu_clave_de_api

Look at the detail in the definition of the fields in schema, the fields have to match the blog collection of the Astro template and then add those that are particular to the collection of Dev.to posts. They have to have the same name as the data type, this is so that we can "merge" the markdown posts from the Astro template with those from Dev.to in the Blog section.

3. Use posts on your pages:

You can now access dev.to posts in your Astro components or pages using getCollection:

Originally:

srcpagesblogindex.astro

import { glob } from 'astro/loaders';
import { defineCollection, z } from 'astro:content';

const blog = defineCollection({
    // Load Markdown and MDX files in the `src/content/blog/` directory.
    loader: glob({ base: './src/content/blog', pattern: '**/*.{md,mdx}' }),
    // Type-check frontmatter using a schema
    schema: z.object({
        title: z.string(),
        description: z.string(),
        // Transform string to Date object
        pubDate: z.coerce.date(),
        updatedDate: z.coerce.date().optional(),
        heroImage: z.string().optional(),
    }),
});

export const collections = { blog };

Now we will do the iteration of the posts with an inline conditional that, if it is devto, will redirect to the url of the article on the site https://dev.to/{username}/{slug-article}

 {
                        posts.map((post) => (
                            <li>
                                <a href={post.collection === "devTo" ? post.data.url : `/blog/${post.id}/`}>
                                    <img width={720} height={360} src={post.data.heroImage} alt="" />
                                    <h4>
