Frontend Architecture Design: Evolution and Solutions

This article discusses frontend architecture design, using Baidu's mobile search scenario as an example to illustrate the evolution and challenges of frontend architecture. It begins by defining frontend architecture as the abstraction and organization of web page components, then analyzes the problems faced by Baidu's search results page, including unclear responsibilities, severe code coupling, and outdated technology stacks.

The article proposes a three-tier approach to address these issues: infrastructure layer (embracing community and open source), independent module layer (solving unclear responsibilities and low delivery efficiency), and componentization layer (accelerating business iteration). It details the implementation strategy, including server-side and client-side designs, and introduces the Molecule interface and dependency injection container.

The article also covers cross-platform solutions and performance optimization, particularly Server-Side Rendering (SSR) and its improvements. It concludes by emphasizing the importance of frontend architecture in meeting business needs and enabling flexible framework and tool upgrades.
