Function corsHeaders

corsHeaders(
    options: {
        origin: string | string[];
        methods?: string[];
        allowHeaders?: string[];
        exposeHeaders?: string[];
        credentials?: boolean;
        maxAge?: number;
    },
): HttpHeaders
Build standard CORS headers.

This function sets headers unconditionally. If you need to merge with pre-existing CORS headers, use the returned HttpHeaders as a base and then apply additional headers after. Do not use Object.assign() or merge functions that may overwrite the Access-Control-Allow-Origin set here.
Parameters
- options: {
      origin: string | string[];
      methods?: string[];
      allowHeaders?: string[];
      exposeHeaders?: string[];
      credentials?: boolean;
      maxAge?: number;
  }
Returns HttpHeaders
Example
```
// As a base - caller adds the rest
const base = corsHeaders({ origin: "https://example.com" });
base.set("Access-Control-Allow-Methods", "GET, POST");
```
