Micro-Frontends with Headless CMS

Micro-Frontends is an architectural style where a single frontend application is composed of smaller, independently deployable frontend applications. A Headless CMS decouples the content management system from the presentation layer, offering flexible content delivery through APIs.

2.1 Micro-Frontends

This architecture allows teams to develop, test, and deploy features independently, leading to faster and more manageable releases.

2.2 Headless CMS

A Headless CMS provides a backend for managing content, which can be served to any frontend technology via APIs, allowing for greater flexibility and scalability.

3.1 Choose Your Tech Stack

• Frontend Framework (React, Vue, Angular)
• Headless CMS (Contentful, Strapi, Sanity)
• Micro-Frontend Framework (Single-SPA, Module Federation)

3.2 Setting up the Headless CMS

npm install -g strapi@latest
strapi new my-project --quickstart

3.3 Creating API Endpoints

Define your content types and create API endpoints in your Headless CMS. For example:

{
  "collections": [
    {
      "name": "articles",
      "attributes": {
        "title": {
          "type": "string"
        },
        "content": {
          "type": "text"
        }
      }
    }
  ]
}

3.4 Developing Micro-Frontend Applications

Use a micro-frontend framework to create your applications. For instance, with Single-SPA:

import { registerApplication, start } from "single-spa";

registerApplication(
  "app1",
  () => import("app1"),
  () => location.pathname.startsWith("/app1")
);

start();

3.5 Integrating Headless CMS with Micro-Frontend

Fetch content from your Headless CMS in your micro-frontend applications:

fetch('https://my-cms.com/api/articles')
  .then(response => response.json())
  .then(data => console.log(data));

• Use a consistent versioning strategy for micro-frontends.
• Implement caching strategies for API responses to enhance performance.
• Ensure proper authentication and authorization for API endpoints.
• Monitor application performance and errors across micro-frontends.
• Keep the UI/UX consistent across different micro-frontends.
