Browsersync use-case

• API
• Gulp
• Grunt
• Nginx

for all other use-cases, (gulp, grunt etc), please show us exactly how you’re using Browsersync

• my plan for the development environment

  firefox <------> nginx (rewrite path, proxy to api) <---(proxy)---> browser-sync (gulp auto build website files)

• browser-sync

browserSync.init({
    socket: {
        path: '/browser-sync/socket.io',
        clientPath: '/browser-sync',
        namespace: '/browser-sync',
        domain: 'testbs.org'
    },
    server: 'public',
    open: true
});

• nginx

server {

    listen 80;
    server_name testbs.org;

    ......

    # BrowserSync
    location / {
        proxy_pass http://localhost:3000/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

    # BrowserSync websocket
    location /browser-sync/socket.io/ {
        proxy_pass http://localhost:3001/browser-sync/socket.io/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

    ......

}

@adambuczek my issue has been resolved by myself😀 let me show you about my configuration:

• nginx

server_name                         test.local.dev
location / {
    # BrowserSync
    proxy_pass                      http://localhost:3010;
    proxy_set_header                Upgrade $http_upgrade;
    proxy_set_header                Connection "Upgrade";
}

• gulp

browserSync.init({
    server: 'public',
    port: 3010,
    ui: {
        port: 3011,
        weinre: {
            port: 3012
        }
    },
    open: false
});

and now, i can do refresh by the test.local.dev, didn’t use the localhost😃

@realmx yes that describes how BrowserSync works.

However, it does not explain why when I run it without nginx it is about 5x faster then if Nginx is implemented. I would expect it to be negligibly slower with nginx, but not 5x slower. It’s IMHO, it’s unusable due to this length of delay.
