About the problem of Nginx reverse proxy?

my site is hosted on the "Code Cloud Gitee" platform. When doing another demo, the request for the site Json file failed due to a cross-domain problem. Du Niang said that the need to rent a server through the "Nginx reverse proxy" solution, but deno can not be developed in the server environment.
is there any good cross-domain approach suitable for my situation? Ask for recommendation! Thank you.
