1. Introduction

In headless and composable architecture, integrating content from multiple sources is essential for creating a seamless user experience. This lesson covers how to effectively gather and unify content from disparate systems.

3.1 Step 1: Identify Content Sources

Determine where your content is coming from. Common sources include:

• APIs (e.g., third-party services)
• Content Management Systems (CMS)
• Databases

3.2 Step 2: Integrate API Data

Use API calls to fetch data. Here’s an example using fetch in JavaScript:

async function fetchData(apiUrl) {
    const response = await fetch(apiUrl);
    const data = await response.json();
    return data;
}
            

3.3 Step 3: Fetch from CMS

Use the CMS's SDK or REST API to retrieve content. Example:

const cmsContent = await cmsApi.getContent('blog-posts');
            

3.4 Step 4: Query Database

Use SQL or NoSQL queries to retrieve data from your database:

SELECT title, body FROM posts WHERE status='published';
            

3.5 Step 5: Transform Data

Standardize the data format across different sources to ensure consistency.

3.6 Step 6: Aggregate Content

Combine the data into a unified structure, ready for rendering in the frontend.

3.7 Step 7: Display in Frontend

Render the aggregated content using your frontend framework.

4. Best Practices

• Ensure API endpoints are secured with authentication.
• Cache responses to improve performance.
• Use a content delivery network (CDN) for static assets.
• Implement error handling for API calls.
• Regularly update and maintain integrations as sources change.
