This can speed up things like First -Contentful Paint, Tie to Interactive, and Speed Index. - -## Enable Nginx Compression with gzip - -In order to enable text compression on Nginx, we need to enable it -within the configuration file: - -```sh -nano /etc/nginx/nginx.conf -``` - -Within the `http` block, find the section that shows -something like the block below. This is the default gzip configuration I -found in my `nginx.conf` file on Alpine Linux 3.17. Yours may -look slightly different, just make sure that you're not creating any -duplicate gzip options. - -```conf -# Enable gzipping of responses. -#gzip on; - -# Set the Vary HTTP header as defined in the RFC 2616.

Here are the full explanations: - -- `gzip` -- Enables or disables gzipping of responses. -- `gzip_vary` -- Enables or disables inserting the "Vary: - Accept-Encoding" response header field if the directives gzip, - gzip~static~, or gunzip are active. -- `gzip_min_length` -- Sets the minimum length of a - response that will be gzipped. The length is determined only from - the "Content-Length" response header field. -- `gzip_proxied` -- Enables or disables gzipping of - responses for proxied requests depending on the request and - response. The fact that the request is proxied is determined by the - presence of the "Via" request header field. -- `gzip_types` -- Enables gzipping of responses for the - specified MIME types in addition to "text/html". The special value - "*" matches any MIME type (0.8.29). Responses with the - "text/html" type are always compressed. -- `gzip_disable` -- Disables gzipping of responses for - requests with "User-Agent" header fields matching any of the - specified regular expressions. - - The special mask "msie6" (0.7.12) corresponds to the regular - expression "MSIE [4-6].", but works faster. Starting from - version 0.8.11, "MSIE 6.0; ... SV1" is excluded from this - mask. - -More information on these directives and their options can be found on -the [Module -ngx~httpgzipmodule~](https://nginx.org/en/docs/http/ngx_http_gzip_module.html) -page in Nginx's documentation. |
