Question 1

How do I set up Module Federation with a React application?

Accepted Answer

Start by following the quick start guide on the official website, which includes configuring your bundler and integrating the runtime. You'll need to define federated modules and set up shared dependencies.

Question 2

What's the difference between Module Federation and webpack 5's built-in federation?

Accepted Answer

Module Federation 2.0 adds features like a manifest, runtime plugins, and dynamic type hints, making it more suited for complex micro-frontend architectures compared to webpack's basic implementation.

Question 3

Does Module Federation work with Vite or other bundlers besides webpack?

Accepted Answer

Yes, it's designed to be bundler-agnostic and can integrate with Vite, Rspack, and others through its runtime system, though setup may require additional plugins or configuration.

Question 4

How can I debug federated modules in production environments?

Accepted Answer

Use the Chrome Devtool extension provided by Module Federation, which allows inspecting module loading, dependencies, and runtime behavior directly in the browser.

Question 5

What are the performance trade-offs when using Module Federation?

Accepted Answer

While it optimizes dependency sharing, dynamic loading can introduce network latency. Implement caching strategies and code-splitting to minimize impact on load times.

Question 6

Is Module Federation better for micro-frontends or code sharing between apps?

Accepted Answer

It excels at both, but is particularly strong for micro-frontend architectures due to its runtime flexibility and tooling, though code sharing across standalone apps also benefits from its dependency optimization.
