DC ModuleFederation Demo

Promise Based Dynamic Remotes

Original docs: https://webpack.js.org/concepts/module-federation/#promise-based-dynamic-remotes

There are two examples of staic and dynamic urls. Each example has two projects:

• app1 is the HOST app
• app2 is the REMOTE app

app2 has dynamic remote url, due to build-tag. For example, it changes every minute.

Instalation

Install packages. Then run app2 and app1.

cd app2
npm ci
npm run start

cd ../
cd app1
npm ci 
npm run start

You will see a web-component from app2 inside app1.

Features

All features are in mf_remotes.js. The only thing you need is to pass an array with tag name and url of remote module. Array example you can find in webpack.config.js.

const remoteModules = [
  { 
    tag:'app2-tag-name', 
    url:'https://localhost:4002' 
  },
]

module.exports = {
  plugins: [
    new ModuleFederationPlugin({
      name: "app1",
      remotes: getRemoteModules(remoteModules)
    }),
    ...
  ]
}
