How to Build Fast, Maintainable Front‑End Products Across Business Scenarios

Business Scenario

We usually evaluate frameworks from four dimensions: business scenario, user experience, development speed, and maintenance cost. The core question is how to quickly launch and maintain a product that meets business needs.

This part explains business needs from the framework perspective.

Integrate with backend frameworks.

Integrate output layers, including Alipay containers, PC and mobile browsers, and component development.

Integrate third‑party services such as analytics and authentication.

Future three years:

More business will require mobile office; mini‑programs will continue to grow.

Complex scenarios like heavy applications, application clusters, WebAssembly, micro‑frontend, and Module Federation will become important.

NoCode/LowCode will occupy a larger share, with developers increasingly adopting platforms such as Cloud‑Fengdie, vertical NoCode tools, and imgcook.

The framework layer will need to make trade‑offs, convergence, and timely reductions as business scenarios proliferate.

User Experience

What is "default usability" and how can we achieve it?

To achieve better UX, front‑end developers and designers must be responsible.

Keep front‑end bundle size small for faster page loads.

Apply proper code splitting, bundle splitting, and on‑demand loading so critical content loads quickly.

Deliver attractive UI with smooth, intuitive interactions.

Implement effective caching and pre‑loading strategies for faster page transitions.

Although 5G promises higher bandwidth, large JavaScript bundles (e.g., 60 MB) still cause multi‑second load times in internal networks, and many UI libraries ignore bundle size.

Future three years for UX:

UI and graphics libraries must be slimmed, support on‑demand loading, proper tree‑shaking, and reasonable on‑demand compilation.

More built‑in performance optimizations at the framework level.

The framework should take over the request layer, providing routing‑based caching and pre‑loading.

If mixed development becomes mainstream, sandbox challenges must be solved, e.g., using module federation or awaiting standardized browser sandbox implementations.

Development Speed

This part explains how to quickly complete development and deliver.

Collaboration across teams is essential, not just the framework.

Accelerate tools, slim frameworks, and provide TypeScript definitions.

Component libraries such as antd, antv, and tech‑ui.

Data preparation, including oneapi.

Smooth delivery via demo centers, mock platforms, and best‑practice integration.

Auxiliary tools.

Future three years for development speed:

Compilation speed will improve dramatically; multiple compilation paths may emerge, with heavy CPU parts implemented in Rust/Go, while the overall solution may combine npm pre‑built CDN and bundless approaches.

Higher‑level vertical domain packaging will integrate framework, UI, data, and data‑flow, enabling rapid mid‑platform application creation (platform or ProCode). Higher abstraction speeds development but reduces customizability, requiring trade‑offs.

Command‑line tools will be insufficient for many scenarios; auxiliary tools such as editor plugins, Chrome extensions, and in‑context editing will further boost efficiency.

Maintenance Cost

Products need both development and ongoing maintenance, especially as frameworks and dependencies evolve.

Cost issues include:

Onboarding cost for new developers.

Handover cost during iteration.

Technology‑stack upgrade cost.

Future three years for frameworks:

Reduce technology‑stack upgrade cost through better top‑level design and abstraction, minimizing migration effort after 3‑5 years of stack changes; balance integration of first‑, second‑, and third‑party solutions with moderate integration, composition, and ejection.

Standardize code practices and best‑practice guides so that the same code can be reused across scenarios; support multi‑platform adaptation (PC + mini‑program) and gradually unify implementations.
