Nginx gzip_static_module配置不起作用

Question

我在Heroku中使用nginx，我想启用http_gzip_static_module 提供压缩文件。我手动压缩我的文件，所以我有例如

bundle.js
bunsle.js.gz

我无法完成这项工作。如果我启用 gzip 动态压缩工作。我对ngnix并不熟悉，我正在使用我在互联网上找到的用于Heroku的配置，或者我应该说我使用的是Heroku buildpack，表示它是受支持的。

现在只有压缩对我很重要。如果我知道什么不重要，我会消除额外的噪音。有什么我应该改变的吗？这是我的配置文件。

daemon off;
#Heroku dynos have at least 4 cores.
worker_processes <%= ENV['NGINX_WORKERS'] || 4 %>;

events {
    use epoll;
    accept_mutex on;
    multi_accept    on;
    worker_connections 1024;
}
