Hey @AndSonder! I'm here to help you with bug fixes, answer questions, and even become a contributor. Let's squash those bugs together! 🤖

The issue you're encountering is related to CORS (Cross-Origin Resource Sharing) when using a custom domain with Vercel for the Pglite database. The error message indicates that the request to fetch the Pglite database bundle is being blocked because the server does not include the Access-Control-Allow-Origin header, which is necessary for CORS.

To resolve this issue, you can try the following steps:

1. CORS Configuration: Ensure that the server hosting the Pglite database bundle is configured to allow requests from your custom domain. This involves setting the Access-Control-Allow-Origin header to your custom domain in the server's CORS settings.

2. Static Hosting: As suggested, you can host the Pglite database bundle on a server where you have control over the CORS settings. This way, you can ensure that the necessary headers are included in the response.

3. Proxy Server: Set up a proxy server that fetches the resource and adds the appropriate CORS headers before forwarding the response to your application.

These steps should help you address the CORS issue and allow the Pglite database to initialize correctly on your custom domain.

top 顶级域名被 npmmirror CDN 拉黑了，临时处理方法是修改下面的资源地址，找一个其他 CDN 的资源吧。

lobe-chat/src/database/client/db.ts

Lines 27 to 35 in ef02986

	// CDN 配置
	private static WASM_CDN_URL =
	'https://registry.npmmirror.com/@electric-sql/pglite/0.2.13/files/dist/postgres.wasm';
	private static FSBUNDLER_CDN_URL =
	'https://registry.npmmirror.com/@electric-sql/pglite/0.2.13/files/dist/postgres.data';
	private static VECTOR_CDN_URL =
	'https://registry.npmmirror.com/@electric-sql/pglite/0.2.13/files/dist/vector.tar.gz';

The top top-level domain name has been blocked by npmmirror CDN. The temporary solution is to modify the resource address below and find a resource for other CDNs.

lobe-chat/src/database/client/db.ts

	private static WASM_CDN_URL =

这个资源就是静态托管享受全球 CDN 加速的。只是 .top 域名黑产过多被拉黑了

Can you directly host this resource statically?
https://registry.npmmirror.com/@electric-sql/pglite/0.2.13/files/dist/postgres.data

This resource is static hosting to enjoy global CDN acceleration. It's just that too many black products of domain names have been blocked

好的了解了，我再试试看其他的 cdn，感谢各位大佬的解惑
