How to Create Scalable Architectures with Vue Micro Frontends

The article details a transformation in Kong's approach to frontend development by adopting a micro frontend architecture, using Vue.js to enhance scalability, maintainability, and developer experience. Initially, the monolithic structure of Kong Konnect's Vue Single-Page Application facilitated rapid feature deployment for a smaller team but eventually led to workflow bottlenecks as the application grew. By transitioning to a micro frontend architecture, Kong's teams achieved autonomous, team-based development, reduced bottlenecks, and enhanced scalability. The new setup includes a developer-optimized monorepo, shared core logic, and standardized testing patterns, which resulted in significantly faster build and release times and improved code quality. The article also highlights the trade-offs faced during this transition, such as maintaining two code versions temporarily and requiring a full page load when navigating between micro frontends. The use of GitHub Actions, S3, and CloudFront for build and deployment processes further streamlined workflows, contributing to a more efficient and scalable development environment at Kong.
