Chapter 11

Prerequisites

The following software is required to run the sample:

• Git
• Node.js
• NPM

Running

Clone the repository:

git clone https://github.com/ArtOfMicrofrontends/11-app-shell.git

Go to the repository's directory and run NPM install:

npm install

Now start the application:

npm start

Steps

Follow these steps to implement the same from scratch.

1. Initialize a new Node.js project and install the dependencies

npm init -y
npm install bootstrap bootstrap-icons regenerator-runtime --save
npm install parcel-bundler cssnano --save-dev

2. Reuse the HTML template from the example written in chapter 10 (SPA composition), no changes needed

3. Most of the app.js from the previous example is still valid, but you'll need to modify the fetching of the MFs:

fetch(feedUrl)
  .then((res) => res.json())
  .then((modules) =>
    modules.forEach((moduleData) => {
      const script = document.createElement("script");
      script.src = moduleData.link;
      script.onload = () => {
        const nsName = moduleData.name;
        const { setup } = window[nsName] || {};

        if (typeof setup === "function") {
          const api = createApi(nsName);
          setup(api);
        }
      };
      document.body.appendChild(script);
    })
  );

4. Add a createApi function for creating an API for each MF
