On mac/linux I had to extract all the generated files by hand to use with a self hosted webserver. I notice the CLI is WIP so not sure if you are aware of this issue. Felt like posting this so anyone who run across this can run the command bellow to fix it with out re rending an entire world (since mine toke over 3 hours to complete)

The command was:

find data/ --name "*.gz" | xargs gunzip

Oh god no! This is intended! :D
The files are saved as .gz to save space (a lot!!) and are sent by the webserver directly using the Content-Encoding: gzip header, so the browser extracts them on the fly..

You can setup your webserver so it does that:
with nginx there is the setting gzip_static always; you can use for the .gz files
and apache can do that as well im sure.

Please don't extract them, they will be up to 20x as big xD

At least there should be an option to generate the non gz versions of the files

I will add that to the config

I think you should notice those who use self hosted webservers to turn the gzip_static option on 😄!

I 'm new to Apache, and I couldn't have my map hosted correctly until I found this issue. Maybe more guys will run into this problem.

Thanks! Anyway it's a great mapping tool!

Update: I still don't know how to configure the Apache to host the map correctly. Of course it's not your fault, but I'll appreciate it if there's any help.

@Sciroccogti Since i am not an apache expert myself, all i can offer you currently is this:
https://coderwall.com/p/sx-8xa/serving-pre-compressed-assets-through-apache

the difference would be that its .json.gz files in our case..

maybe you can adapt from that

@TBlueF It's very kind of you to offer the tutorial, but it's still not working.

I have now switched to Nginx, however it turns out that my website is not working yet.

I'm sorry to bother you, but could you PLZ have a look at my conf in nginx/sites-enabled/?

server {
        listen 80;
        listen [::]:80;

        server_name map.sciroccogti.top;

        root /path/to/BlueMap/web/;
        index index.html;

    gzip on;
    gzip_static on;
    gzip_http_version 1.1;
    gzip_disable "MSIE [1-6]\.";
    gzip_vary on;
    gzip_proxied expired no-cache no-store private auth;
    #gzip_types text/plain text/json  application/x-javascript text/xml application/xml application/xml+rss text/javascript application/json;

    #return 301 https://$server_name$request_uri;

        location / {
                try_files $uri $uri/ =404;
        }
}

BTW, I noticed that gzip over ssl is not safe, is that true?

@Sciroccogti Sorry, i can and will not help you here with bluemap unrelated issues.
Also, the "gzip over ssl is not safe" link you posted links to an issue with nginx from 2014 that has been resolved.

@TBlueF That's OK. Thanks anyway.

I figured it out. The lines about location make the server no working. The successful conf is list below:

server {
        listen 80;
        listen [::]:80;

        server_name map.sciroccogti.top;

        root /path/to/BlueMap/web/;
        index index.html;

        gzip off;
        gzip_static on;
        gzip_proxied expired no-cache no-store private auth;
}

Just in case anyone else wants to know how to get this working on their Apache webserver, I figured it out.
Tweak the following to suit your setup.

DocumentRoot /var/www/
<Directory /var/www/>
allow from all
Options FollowSymLinks
Require all granted
SetEnv no-gzip

        RewriteEngine on

        # Make sure the browser supports gzip encoding before we send it
        # without it, Content-Type will be "application/x-gzip"

        RewriteCond %{HTTP:Accept-Encoding} \b(x-)?gzip\b
        RewriteCond %{REQUEST_FILENAME}.gz -s
        RewriteRule ^(.+) $1.gz [L]

    # Also add a content-encoding header to tell the browser to decompress

    <FilesMatch .gz$>
        ForceType application/json
        Header set Content-Encoding gzip
    </FilesMatch>
    
</Directory>

Edit - I forgot to note that this needs the HEADERS and REWRITE mods for Apache enabled.
