digitalmars.D - minifying the website

reply Andrei Alexandrescu <SeeWebsiteForEmail erdani.org> writes:
Hello,


I've been looking through the logs and it looks like the top files in 
bytes transferred yesterday (even with the deluge of downloads) were a 
number of Javascript, HTML, and CSS files.

There are programs to reduce the size of such files called "minifiers". 
Should we use some? If so, what would the experts recommend? We'd need 
ideally some command line utility that we can deploy easily and 
integrate with the build process. Alternatively, an online service could 
fit the bill, too.


Thanks for your insights,

Andrei

I recommend YUI Compressor. http://yui.github.io/yuicompressor/ I 
use it for compressing JavaScript and CSS at my job, and it works 
very well. (It's also part of a Maven build script at my job, 
which is also cool.) If you use it, I recommend --nomunge 
--preserve-semi --disable-optimizations so it doesn't do any 
JavaScript fiddling beyond just minification.

Thanks. I'm a bit weary of adding Java as a requirement for building. Is 
that a legitimate concern?

I would add it as a separate make target, which is not needed for

Well, some requirement must be added as I'm unaware of good 
minifiers that do not require a runtime. But I would always go 
with Node.js instead of Java.

IMHO these days to be serious web developer you must have Node.js 
installed, as NPM modules have become de facto standard for 
distributing libraries and utilities for web development.

For Node.js minifiers I recommend uglify.js 
(https://github.com/mishoo/UglifyJS2) for JavaScript and 
clean-css (https://github.com/GoalSmashers/clean-css) for CSS.

And for server configuration take a look at

Are these files gzipped? gzipping them will almost certainly give

Browsers send Accept-Encoding headers to let the webserver know 
if gzip is viable, and webservers send gzip if they can, 
supposing they are configured to use gzip. All modern browsers 
should send the right headers, old ones will have fallbacks.

I'd just upload a file.html.gz (gzip file.html on your own 
computer) and then try to go to dlang.org/file.html

It might just work. If that doesn't, rename file.html.gz to 
file.html and again try it, if it just works, add gzip to your 
build process then upload.

If it doesn't just work, and .htaccess is enabled, try adding 
this to your .htaccess file and then try again:


<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{HTTP:Accept-encoding} gzip
    RewriteCond %{HTTP_USER_AGENT} !Safari
    RewriteCond %{REQUEST_FILENAME}.gz -f
    RewriteRule ^(*.html)$ $1.gz [QSA,L]
<FilesMatch \.html\.gz$>
    ForceType text/html
    Header append Vary Accept-Encoding
</FilesMatch>
</IfModule>
<IfModule mod_mime.c>
    AddEncoding gzip .gz
</IfModule>


that just does html, the regexs will need matching for js and css 
too, but that should work. I use this on one of my computers to 
serve up file.html.gz as file.html transparently.

BTW I suck at apache config and hate doing it (this is why my 
cgi.d has a gzip flag among others - easier to do in D than 
httpd.conf!) so if someone has a better way please overrule me.

Yeah, and if not the server will most likely unzip it for you as 
needed.

This displays the same garbled compressed content straight in the browser.

Which hosting company do you guys use? Disabling .htaccess seems 
too unprofessional..

Anyway, I was under impression that dlang.org is hosted from some

 about it is that its configuration is so much easier to deal 
 with. It
 still isn't trivial, and I still have to think about what I'm 
 doing,
 but it's not nearly as painful (for me, anyway) as Apache 
 configuration.

 Couldn't agree more. I've switched to nginx few years back and 
 haven't regretted it a bit.


Yea. The only downside I've heard people say about Nginx was that it
was supposedly much lighter on features than Apache, but honestly, I
don't see that at all. It seems to have all the bells & whistles I can
think of ever needing.

Got similar results. Quite dramatic. So what should I tell our admin?

He would need to install mod_pagespeed: 
https://developers.google.com/speed/pagespeed/module/download

Do some typical Apache configuration (enabling the module for the 
Virtual Host and whatnot): 
https://developers.google.com/speed/pagespeed/module/configuration

Just using the default CoreFilters is probably fine.

Also, unless I'm mistaken, the dlang.org files don't appear to be 
gzipped. (Content-Encoding: gzip) Using gzip should massively 
reduce network IO. gzip works very well on HTML, JavaScript, 
JSON, and CSS, as there are a lot of redundant words used.

It would be also great if you could remove that flashing after 
the page is loaded.
I believe it's caused by the bodyLoad() function. Why is it even 
needed?

I may be in the minority in this, but I would prefer if some of 
that were just removed entirely.

In particular, the code-running doohickey that doesn't even work 
needs to die for the pathological behaviour it gives on Firefox.  
For example http://dlang.org/phobos/std_algorithm.html hung my 
browser for almost twenty seconds with a blank coloured 
background.  This is on an i5 at work and my i7 at home, with or 
without extensions.  I can't even imagine how my old laptop would 
cope.  To add insult to injury, it displayed the page without the 
JS for almost a second before disappearing.

I'm fine with some light JS that makes the documentation more 
usable or useful; this makes it practically unusable unless I 
have access to NoScript.

I actually second this. I block those scripts because they slow 
the pages down massively, and often break. I'm using Firefox on 
Windows with a beefy i7.

+1.

I browse dlang.org with JS turned off because it's much more usable that
way. I've no idea what the JS does (the only visible effect I can see is
the ugly blob of unreadable links in the Phobos docs which are useless
anyway -- the links, I mean, not the docs), but it makes page contents
vanish for a good number of seconds, causes my browser to soak up memory
like a sponge, and results in poor performance in general.

We should either fix whatever is causing the performance hit, or just
get rid of it altogether.


[...]

Due to several sites that recently insisted on adding heavy-duty JS that
doesn't add any significant functionality, I've turned off JS by default
and only enable it on a site-by-site need-to basis (I use Opera that has
per-site preferences built-in). The web is surprisingly faster and
easier to use that way.

(Most people will probably think I'm nuts, though. And they're probably
right. :-P *shrug*)

The site currently isn't configured to serve gzip / deflate 
compressed content. Fixing this will lower bandwidth usage in a 
much more significant way than serving minified files would. I 
think mod_deflate is used for this in Apache.
