This skill helps you add PostHog analytics to Angular applications.

本技能可帮助你为Angular应用添加PostHog分析功能。

Workflow

工作流程

Follow these steps in order to complete the integration:

```

```
- PostHog Setup - Begin ← Start here
```
basic-integration-1.1-edit.md
```
- PostHog Setup - Edit
```
basic-integration-1.2-revise.md
```
- PostHog Setup - Revise
```
basic-integration-1.3-conclude.md
```
- PostHog Setup - Conclusion

按照以下步骤完成集成：

```
basic-integration-1.0-begin.md
```
- PostHog 设置 - 开始 ← 从此处开始
```
basic-integration-1.1-edit.md
```
- PostHog 设置 - 编辑
```
basic-integration-1.2-revise.md
```
- PostHog 设置 - 修改
```

Key principles

核心原则

Environment variables: Always use environment variables for PostHog keys. Never hardcode them.
Minimal changes: Add PostHog code alongside existing integrations. Don't replace or restructure existing code.
Match the example: Your implementation should follow the example project's patterns as closely as possible.

环境变量：始终使用环境变量存储PostHog密钥，绝不要硬编码。
最小改动：在现有集成代码旁添加PostHog代码，不要替换或重构现有代码。
匹配示例：你的实现应尽可能贴近示例项目的模式。

Framework guidelines

框架指南

Use inject() instead of constructor injection. PostHog service should be injected via inject() in components/services that need it.
Create a dedicated PosthogService as a singleton root service that wraps the PostHog SDK.
Always use standalone components over NgModules.
Configure PostHog credentials in src/environments/environment.ts files, as Angular reads environment variables from these configuration files

使用inject()而非构造函数注入。需要PostHog服务的组件/服务应通过inject()注入该服务。
创建专用的PosthogService作为单例根服务，用于封装PostHog SDK。
优先使用独立组件而非NgModules。
在src/environments/environment.ts文件中配置PostHog凭据，因为Angular会从这些配置文件读取环境变量

Identifying users

用户识别

Identify users during login and signup events. Refer to the example code and documentation for the correct identify pattern for this framework. If both frontend and backend code exist, pass the client-side session and distinct ID using

X-POSTHOG-DISTINCT-ID

and

X-POSTHOG-SESSION-ID

headers to maintain correlation.

在登录和注册事件中识别用户。请参考示例代码和文档，获取适用于该框架的正确识别模式。如果同时存在前端和后端代码，请使用

X-POSTHOG-DISTINCT-ID

和

X-POSTHOG-SESSION-ID

标头传递客户端会话和唯一ID，以保持关联。

Error tracking

错误追踪

Add PostHog error tracking to relevant files, particularly around critical user flows and API boundaries.

为相关文件添加PostHog错误追踪，尤其是关键用户流程和API边界附近的文件。
