Enterprise Micro-Frontends in 2026: Module Federation 2.0 with Rspack and Turborepo

In hyperscale enterprise engineering organizations (Fortune 500 fintech, travel aggregators, multi-tenant SaaS platforms), monolithic frontend codebases collapse under team growth:

• The Monolithic Deployment Bottleneck: 60 frontend engineers work across 12 different product squads (Auth, Checkout, Billing, Analytics, Settings). A single typo in the Analytics squad’s code blocks the weekly production release for all 12 squads.
• The Webpack Build Time Stall: Monolithic Webpack codebases take 8 to 15 minutes to build in CI/CD, stalling developer feedback loops and slowing hot-module replacement (HMR) to 6 seconds per save.
• The Early Module Federation Flaws: Early Module Federation v1 suffered from brittle runtime type mismatches (any types across remotes), duplicate library bundling (downloading three separate versions of React), and tight coupling to Webpack 5.

In 2026, Module Federation 2.0 (MF 2.0), Rspack, and Turborepo have established the Definitive Enterprise Micro-Frontend Architecture.

By decoupling runtime micro-frontend composition from the underlying bundler and leveraging Rust-powered compilation (Rspack) and Turborepo monorepo orchestration, enterprise organizations achieve instant independent deployments, sub-second local HMR, and compile-time TypeScript type safety across remote boundaries:

• Module Federation 2.0 (Bundler-Agnostic): Running seamlessly across Rspack, Webpack, Vite, and Rolldown with dynamic manifest discovery.
• Automated Cross-Remote TypeScript Sharing (@module-federation/typescript): Automatically generating .d.ts declaration bundles so host apps get compile-time autocomplete and type checking on remote components.
• Multiple Share Scopes & Tree-Shaking: Ensuring singletons for React context providers while dynamically tree-shaking unused shared utility libraries.
• Rspack Rust Compilation: Slashing build and test times by 10x across multi-package monorepos.

In this deep architecture guide, we break down Module Federation 2.0 mechanics, evaluate shared scope dependency isolation, and implement a production Host Shell + Remote Billing Micro-Frontend Pipeline based on enterprise platforms engineered at MojoStudio.

3. Production Code: Rspack Configuration for Remote Micro-Frontend

Here is the production configuration using Rspack and Module Federation 2.0 for a remote Billing Micro-Frontend:

// apps/billing-remote/rsbuild.config.ts
import { defineConfig } from "@rsbuild/core";
import { pluginReact } from "@rsbuild/plugin-react";
import { pluginModuleFederation } from "@module-federation/rsbuild-plugin";

export default defineConfig({
  server: {
    port: 3001,
  },
  plugins: [
    pluginReact(),
    pluginModuleFederation({
      name: "billing_remote",
      filename: "remoteEntry.js",
      // 1. Expose Micro-Frontend Component to Host Shell
      exposes: {
        "./BillingDashboard": "./src/components/BillingDashboard.tsx",
        "./InvoiceTable": "./src/components/InvoiceTable.tsx",
      },
      // 2. Shared Dependencies with Singleton Enforcement
      shared: {
        react: {
          singleton: true,
          requiredVersion: "^19.0.0",
          eager: false,
        },
        "react-dom": {
          singleton: true,
          requiredVersion: "^19.0.0",
          eager: false,
        },
        "@tanstack/react-query": {
          singleton: true,
        },
      },
      // 3. Automated Compile-Time TypeScript Definition Generation!
      dts: {
        generateTypes: true,
      },
    }),
  ],
});

4. Production Code: Host Shell Consuming the Remote Component

// apps/shell-host/rsbuild.config.ts
import { defineConfig } from "@rsbuild/core";
import { pluginReact } from "@rsbuild/plugin-react";
import { pluginModuleFederation } from "@module-federation/rsbuild-plugin";

export default defineConfig({
  server: {
    port: 3000,
  },
  plugins: [
    pluginReact(),
    pluginModuleFederation({
      name: "shell_host",
      // Dynamic Remote Manifest Resolution
      remotes: {
        billing_remote: "billing_remote@http://localhost:3001/mf-manifest.json",
      },
      shared: {
        react: { singleton: true, requiredVersion: "^19.0.0" },
        "react-dom": { singleton: true, requiredVersion: "^19.0.0" },
      },
      dts: {
        consumeTypes: true, // Automatically fetches and types remote imports!
      },
    }),
  ],
});

// apps/shell-host/src/App.tsx
import React, { Suspense, lazy } from "react";

// 100% Strongly-Typed Remote Import via @module-federation/typescript!
const BillingDashboard = lazy(() => import("billing_remote/BillingDashboard"));

export function App() {
  return (
    <div className="min-h-screen bg-slate-950 text-white">
      <nav className="p-4 border-b border-slate-800 flex justify-between">
        <h1 className="font-extrabold text-xl">Enterprise Portal</h1>
        <span>User: Sachin Sharma</span>
      </nav>

      <main className="p-8">
        <Suspense fallback={<div className="p-8 text-center">Loading Billing Micro-Frontend...</div>}>
          <BillingDashboard organizationId="org_98420" />
        </Suspense>
      </main>
    </div>
  );
}

5. Turborepo Monorepo Orchestration (turbo.json)

Turborepo caches and orchestrates builds across all micro-frontends with parallel execution:

{
  "$schema": "https://turbo.build/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "outputs": ["dist/**"]
    },
    "dev": {
      "cache": false,
      "persistent": true
    },
    "lint": {
      "outputs": []
    }
  }
}

Frequently Asked Questions

1. What are Micro-Frontends?

Micro-frontends is an architectural pattern where an independently deliverable frontend application is decomposed into smaller, semi-independent micro-apps that are dynamically composed into a single unified user interface at runtime.

2. What is Module Federation 2.0?

Module Federation 2.0 is the modern, bundler-agnostic evolution of Webpack's module federation, supporting Rspack, Vite, Webpack, and Rolldown with dynamic manifest discovery, runtime plugins, and automated cross-remote TypeScript type sharing.

3. What is Rspack?

Rspack is a high-performance, Rust-based web bundler developed by ByteDance that is 100% compatible with the Webpack ecosystem, delivering 5x to 10x faster build times and instant Hot Module Replacement (HMR).

4. How does @module-federation/typescript ensure type safety across micro-frontends?

During the build process, the plugin extracts TypeScript interfaces from exposed components, bundles them into .d.ts declaration files, and automatically downloads and links them inside the host application, enabling full compile-time autocompletion and type checking.

5. What is a Singleton Dependency in Module Federation?

A singleton dependency (such as react or @tanstack/react-query) guarantees that only a single instance of the library is loaded in browser memory, preventing broken context providers and state collisions between the host shell and remote micro-frontends.

6. What is Turborepo?

Turborepo is an advanced, high-performance monorepo build system for JavaScript and TypeScript that uses intelligent task hashing, parallel execution, and remote caching to speed up local development and CI/CD pipelines.

7. How does Module Federation 2.0 handle remote discovery?

MF 2.0 uses a dynamic mf-manifest.json protocol, allowing host applications to query the remote endpoint at runtime to discover the latest chunk hashes and assets without redeploying the host application.

8. What are Multiple Share Scopes?

Multiple share scopes allow different micro-frontends to isolate incompatible dependencies (e.g. running an older React 18 remote alongside a React 19 host) without crashing the global application runtime.

9. When should an organization adopt Micro-Frontends?

Micro-frontends should be adopted when an engineering organization has multiple autonomous product squads (> 30+ engineers) whose deployment velocity is bottlenecked by a single monolithic frontend repository.

10. How does MojoStudio help companies implement Micro-Frontends?

MojoStudio designs enterprise Module Federation 2.0 architectures, migrates legacy Webpack monoliths to high-speed Rspack monorepos, configures Turborepo build caching, and implements automated cross-remote TypeScript pipelines. Explore our Backend & Web Services to learn more.
