# 5. createRouterMatcher()

```typescript
// 文件 matcher/index.ts
export function createRouterMatcher(
  routes: Readonly<RouteRecordRaw[]>,
  globalOptions: PathParserOptions
): RouterMatcher {
  // 标准化有序数组 matchers
  const matchers: RouteRecordMatcher[] = []
  const matcherMap = new Map<RouteRecordName, RouteRecordMatcher>()
  globalOptions = mergeOptions(
    { strict: false, end: true, sensitive: false } as PathParserOptions,
    globalOptions
  )
  
  // ...
  
  // 添加初始 routes，将路由配置转化为 matcher
  routes.forEach(route => addRoute(route))

  return { addRoute, resolve, removeRoute, getRoutes, getRecordMatcher }
}
```
