Compression

Next.js provides gzip compression to compress rendered content and static files. Compression only works with the server target. In general you will want to enable compression on a HTTP proxy like nginx, to offload load from the Node.js process.

To disable compression, open next.config.js and disable the compress config:

module.exports = {
  compress: false,
}
