React 开发

# 让 React 界面随着产品成长，依然容易理解和维护。

仪表盘看起来已经完成，加载状态、权限和未保存的修改却仍可能让用户困惑。我们从用户真正要完成的任务出发，开发和改进 React 前端，明确状态的归属，并留下团队能够继续维护的组件。

合作方式

## 明确范围、实现与验收。

1. **梳理交互** 追踪数据、权限和失败路径。
2. **实现完整状态** 为组件定义清楚的行为。
3. **验证用户流程** 执行约定流程并交接代码。

直接回答

React 开发面向已有或计划中的产品交互层，涵盖组件、状态、API 连接、无障碍交互以及真实使用条件下的行为。双方先确定要改进的用户流程，再约定验收方式。

适合

- 已有 React 产品越来越难修改的团队
- 需要在现有后端之上构建复杂且易用界面的产品

可考虑其他服务

- 尚未明确产品方向、仍需需求探索的想法
- 主要需求是内容编辑与发布的公共网站

## 从一个难以完成的用户任务开始

账户页面、运营仪表盘或多步骤编辑器都可以成为清晰的工作边界。修改组件树之前，我们先梳理相关数据和状态。如果产品本身尚未定义，应先进行 [软件需求探索](/zh/services/software-discovery/) 。完整 Web 产品的交付由 [Web 应用开发](/zh/services/web-apps/) 承接；本服务可以只处理其中的前端。

## 区分共享数据与临时界面状态

我们确定哪些值应放在 URL、服务端数据缓存、表单或组件本地状态中。加载中、无数据、数据过期、无权限和请求失败等状态，与成功响应一起设计。实现内容包括键盘操作、控件标签、有针对性的组件测试和 API 错误处理。先测量渲染问题，再决定是否引入缓存优化或新的状态库。

## 保存失败后仍能继续工作的审核队列

示例验收场景：操作员筛选队列、编辑记录，并在保存时断网。输入内容仍然可见，失败请求与已完成更新能够区分，重试不会重复执行操作，浏览器前后导航能够恢复约定的筛选条件。我们记录测试角色、浏览器条件和后端假设。这是用于讨论的验证方案，并非既有客户项目的成果。

## 把重构拆成可以审查的小步

第一项交付是受影响组件、接口约定和风险的梳理。随后决定扩展现有结构，还是替换一个边界明确的部分，并沿用当前发布流程交付可审查的改动。跨多个产品使用的组件库属于 [设计系统](/zh/services/design-systems/) 范围。涉及整个框架的迁移可由 [旧系统现代化](/zh/services/legacy-modernization/) 统筹。

## 让下一位开发者理解如何继续

您会收到源代码、相关测试、状态与 API 假设，以及新增页面的说明。我们参考 [React 关于组件和状态的官方指南](https://react.dev/learn/thinking-in-react) ，同时根据实际应用作出选择。启动工作需要代码仓库访问权限、可复现的环境、API 响应示例，以及能够确认预期行为的负责人。

## 开始之前的问题

### 可以在现有 React 应用中工作吗？

可以。我们先了解构建方式、组件约定和关键用户流程，再提出改动建议。一个独立的小范围改进，通常比直接替换架构更适合作为起点。

### 是否包括后端开发？

只有在范围中明确列出时才包括。我们会记录需要调整的 API，并可与前端一起估算和安排。现有后端的责任归属会保留在交付计划中。

### 这与 Next.js 开发有什么区别？

本页关注 React 交互与前端结构。如果路由、渲染、服务端边界或框架部署是主要问题，应选择 Next.js 服务。

### 所有组件都会被纳入设计系统吗？

不会。只有出现重复使用需求时，才提炼共享模式。具有版本管理、文档和跨团队推广要求的组件库，需要单独约定范围。

## 选择合适的下一步

- [Next.js 应用工程](/zh/services/nextjs-development/)
- [跨产品共享组件](/zh/services/design-systems/)
- [构建完整 Web 应用](/zh/services/web-apps/)
