Hire Module Federation experts for your next project

Module Federation lets internal and external teams develop features in isolation, each with its own release cadence. We help you turn this architecture into a secure, scalable platform—so you can move fast without losing control.

At Scale

Why you should use Module Federation

Module Federation allows teams to build scalable, decoupled frontends—shipped independently across platforms and business domains.

Independent releases

Update parts of your app without waiting for the whole monolith to rebuild or redeploy.

Decoupled teams

Teams can own, ship, and maintain isolated features—without stepping on each other’s toes.

Framework and platform agnostic

Modules can use different technologies or frameworks, and still compose into a single app at runtime—no rewrites or coupling required.

PARtner CASE STUDY

Southern Glazers is using Module Federation on both web and mobile to ship faster

Southern Glazer's Wine & Spirits (SGWS) leveraged Module Federation with Re.Pack and Zephyr Cloud to transform their deployment processes. By splitting their applications into independently deployable modules, SGWS achieved sub-second deployments and rollbacks, which allowed for almost instantaneous updates to compliance fixes and new features.

COMMON CHALLENGES

What should you look out for when adopting Module Federation?

Module Federation can unlock serious scale—but it’s not plug-and-play. From version conflicts to bundle bloat and mobile-specific issues, you’ll want to plan ahead to avoid common integration problems.

Version conflicts

Different remotes can bring different versions of shared packages—leading to inconsistent runtime behavior.

Dependency duplication

Lack of clear sharing strategy can increase bundle size and runtime bugs.

Runtime failures

Remotes can fail to load or behave unexpectedly without proper fallbacks and observability.

Performance overhead

Dynamic loading and fallback logic adds cost—especially without good caching or chunking.

Shared state

Isolating features is easy. Sharing context or state between them isn’t.

Cross-platform integration

Federating between web and mobile brings additional build, runtime, and API challenges.

Hire engineers who pioneered Module Federation in React Native

Use Module Federation with React Native

Build mobile apps that download features dynamically at runtime—without needing an app store release. It’s a perfect solution for splitting large apps or decoupling teams.

Build cross-platform federated modules

Design modules once and run them anywhere: mobile, web, or desktop. We will help you create truly platform-agnostic packages ready to be composed into any host.

Build SDKs and infrastructure for third-party developers

Expose your modules to external teams through a lightweight SDK layer. Design interfaces and dev workflows that make it easy for others to build in isolation and ship safely.

FAQs

Implementing Module Federation across platforms can raise questions about tooling, performance, and integration boundaries. Here are some of the most common technical topics we cover with clients building federated frontends.

What platforms does Module Federation support?

We can implement federation across web, mobile (including React Native), and desktop apps using compatible tooling and custom adapters.

Can you use Module Federation with React Native?

Yes. We’ve developed and open-sourced tooling that makes federation work in React Native by handling bundling, loading, and native bridges where needed.

Can I load modules from different platforms (e.g., web into native)?

Yes, with careful packaging and platform-specific wrappers, we can support federation across platform boundaries.

How do we ensure security when loading remote code?

We implement domain whitelisting, checksum validation, and CI pipelines that validate remote packages before production use.

Can third-party developers build features independently?

Absolutely. We can provide a lightweight SDK and development environment to allow external teams to build, test, and deploy in isolation.
