If you had JavaScript running server-side...? - Page 2

Peter Michaux

I'm writing a server-side web application framework using Mozilla's
Rhino JavaScript engine. My two primary motivations are so I can write
code on server and client sides without needing to switch gears
mentally and so that the server and client can share code.

The types of code sharing I know I can use immediately are form
validations and html previews. For form validation, I'll be able to
specify the regexp for what is an email address in just one language
rather than in both Perl|Python|Rub y|Java|etc and in JavaScript. For
something like a blog comment form or a wiki editor, where the user
can use *bold* or _underline_ syntax, the algorithm to convert this
code to HTML will only need to be expressed in one language. This
makes live previews in the editor much easier to implement.

I'm curious what other bits of common (or uncommon) client-side
functionality that you would be able to share with the server if you
had server-side framework running JavaScript.

Thanks,
Peter

It works, but it makes little sense, if any. Despite what Google Groups and
other mirrors want you to believe, Usenet is not on the Web.
Nobody said Usenet is on the Web. The archives for Usenet are on the Web
though. And that is what Peter linked to was the archive of that post.

Several, but not all, Usenet archives are available via the Web.

Nobody said there weren't any available on the Web.

Those that are on the Web are neither complete, nor do they always present the original
article.

Can you show an instance where Google Groups didn't present the original
article?

Google Groups in its current form makes no exception.

Example? I am not referring to you trying to cancel a message and it
getting archived anyway. I am asking you for an instance where GG did
not present the original article. Meaning, Google Groups modified it in
some way.

There is one thing GG does, and that is adding trailing spaces.

Furthermore, Web archives are not required to access an article that was
posted only a few days ago; there is no public news server that has such a
short expiration setting.

We are not discussing "Web archives" and some that won't "show an
article a few days ago". We are discussing Google Groups and the ability
to use Google Groups as a reference to an older article.

And if my articles eventually expire, both will only be available in the
archives, be they public or private.

Nobody said any differently.

Nothing you have said is any more true/false about web archives than
Usenet servers.

In fact, my (Google) research showed that providers of public Usenet
archives have been going to great lengths to support `news:' URIs in
the way I posted as being rewritten to links to their archives.

Nobody said any differently. What I said was that your style of
referring to old posts is unreliable. Posting a URL to a Google copy of
it is.

[snip regarding linking to news archives]

So do you guys have any thoughts about sharing code on the client and
server sides? ;-)

I tried ASP once with JScript, gave me more headaches than I care to
remember. I kept getting confused about where I was, client or server.
Switched to PHP and haven't looked back.
