Creating a multi-tenant architecture with JavaScript Module Federation and Webpack 5

In today’s era of cloud computing and SaaS applications, building software that can serve multiple tenants (customers) efficiently and securely is becoming more important than ever. One way to achieve this is by using a multi-tenant architecture, where a single instance of an application serves multiple tenants while keeping their data and functionality isolated.

In this blog post, we will explore how to create a multi-tenant architecture using JavaScript Module Federation with Webpack 5. We will leverage the power of Module Federation to dynamically load tenant-specific modules within a shared application shell.

What is JavaScript Module Federation?

JavaScript Module Federation is a feature introduced in Webpack 5 that allows you to share modules across different JavaScript applications. It enables you to create a federated architecture where multiple applications can dynamically consume and provide modules to each other at runtime. This can reduce duplication of code and improve the performance and scalability of your applications.

Designing a Multi-Tenant Architecture with Module Federation

To implement a multi-tenant architecture using Module Federation, we can follow these steps:

  1. Create a Shared Application Shell: Start by creating a shared application shell that will serve as a shared base for all the tenant-specific modules. This shell should include common functionality, such as header, footer, navigation, and authentication logic.

  2. Configure Webpack for Module Federation: Configure Webpack to enable Module Federation in both the shared application shell and the tenant-specific modules. Specify the shared modules that will be used across different applications.

  3. Dynamic Loading of Tenant-Specific Modules: Use the Module Federation API to dynamically load the tenant-specific modules into the shared application shell. Each tenant-specific module should contain only the specific functionality required by that tenant, while the shared application shell provides the common features.

  4. Implement Tenant Isolation: Ensure that the tenant-specific modules are isolated from each other, both at runtime and in terms of data storage. Use techniques like sandboxing or virtualization to prevent unauthorized data access between tenants.

Benefits of Using Module Federation for Multi-Tenant Architecture

Using JavaScript Module Federation with Webpack 5 for building a multi-tenant architecture brings several benefits, including:

Conclusion

Building a multi-tenant architecture is crucial for SaaS applications, and JavaScript Module Federation with Webpack 5 provides an excellent solution to achieve this. By leveraging Module Federation, we can create a modular and scalable architecture that enables code sharing, dynamic loading, and tenant isolation.

Now is the time to explore the power of Module Federation and take your multi-tenant applications to the next level of flexibility, performance, and security.
