#36105 — Server side JS programming

Hi,
I think I've asked this question before over here, but it seems to have slipped my mind what was said - I'd like to know: is there any way to do server side programming in JS to generate a webpage, with the code bits "inserted" into the HTML bits, like <?php does for PHP? Otherwise, how would you say, print stuff from a MySQL database (assuming you're using node.js) on a webpage? You'd need some way to separately print the MySQL data, and *then* (if it comes afterwards) print the rest of the HTML. Ugh! This is Horrifying! Surely there must be a better solution?

Thanks.

Using Classic ASP as a platform, you can use Jscript,
which is an nowadays antiquated form of Javascript by Microsoft.

Of course, there is no serverside DOM, so there are other commands to 
interact with that environment. 

<%@ LANGUAGE="jscript" %>
<h3>
<%
var num = 8 / 17;
var yes = true;
if (yes) Response.write( num + ' is not an integer.' );
%>
</h3>

There has been Server-side JavaScript on Netscape Enterprise Server and its
successors.

Nowadays only ASP (.NET) with JScript (.NET), and Node.js with Google V8
JavaScript come to mind.

This is not “otherwise”, so I do not follow.

No, you can wait for the data to arrive.  Also, you can only query and
display chunks of the data, and cache them server-side and client-side.

> Ugh! This is Horrifying! Surely there must be a better solution?

Usually chunking and/or AJAX/XHR/Fetch is the proper solution nowadays.
The programming language used server-side is secondary.

Er no - I NEVER post under my own name on the net. Been bitten before, second time shy.
Oh - I've had quite a few "conversations" with my old pal Evertjan on over here :) (which mainly consisted of him being the usual sarcy bastard that he is *consistently*!)

Ignore Pointed 'RealName' Ears, he has imaginary netiquette rules
that he insults almost everyone for breaking. There is no need to
pay any attention to his nonsense.

In now 19 years of posting in Usenet under my real name I have never had any
problems with people in real life, despite a host of statements on my part
that were perceived by some to be controversial.  On the contrary, I have
made real-life acquaintances and friends, and the demonstration of my
expertise online helped me to find good, well-paid positions in the software
industry several times.

Assuming your story to be true, probably your problems had to do with *how*
and *what* you posted, as it has to do whether you have the courage to stand
by your own words with your own, real name.  For it is too easy to throw
insults while hiding behind *seeming* anonymity.

/Argumentum ad hominem./

Jon Ribbens is fully aware that “PointedEars” is my nickname and that it is
customary to include it *in addition to* the real name (not least to avoid
confusion with other people), which in my case is Thomas Lahn.  As it says
in the From header field of each of my postings, in my Twitter account, and
so on.

Showing the simple courtesy to introduce oneself to strangers before
asking for their free help is not a fantasy, let alone mine.  And showing
courtesy when interacting with one another is indeed the core of what is
called “etiquette”; on the Net, “network etiquette” or “netiquette” for short.

As a result, when that courtesy is not shown, one must expect one’s audience
to be greatly reduced to those who do not put much value, if any, in
courtesy.  So it is illogical to expect it from them then.

See also, among other sources:

<http://www.albion.com/netiquette/corerules.html>

To perceive or portray a request for that courtesy as an insult indicates
a twisted sense of reality at best.

Hard time keeping a position?

Now that is some of the best twisted logic I have ever read.

In your universe.

No, no, no. You cannot tell others about courtesy when you so
frequently, and I posit, intentionally, are discourteous.

> To perceive or portray a request for that courtesy as an insult
> indicates a twisted sense of reality at best.

<shaking head> Dude, you are constantly discourteous. So, you have a
"twisted sense of reality". Thanks for confirming.

OK, TLDR; but - well, good for you, however it was not the case with me. I just... dont' *want* a lot of folks to know what I'm up to, online - is there anything wrong with that??

And I'm not "hiding" under anything, unless you suggest that I travel all the way  to the Netherlands, half a world away, so that I can "chat" with Evertjan :)

Rarely.

Did you not follow the "Getting started" guide?

I *did* take a cursory look at those pages (and others on that site), but nowhere did I see HTML *interspersed with* server-side Javascript...?

That's because it doesn't do that.

You don't seem to have looked into my suggestion of 'jsdom'.

If you are learning something unfamiliar, then a cursory glance would hardly do you any good. If you spent enough time to actually click the demo on the hello-word page you would see that it responds with a content-type of text/html. That would be enough of a hint to derive that the following is possible:

    app.get('/', (req, res) => res.send('<h1>Hello World!</h1>'))

and therefore more complicated forms or responses

Of course.  Why take the time to read what others have taken time to write?
You only care about yourself.

Certainly:  Usenet is the thing with *people*.

You appear to have acquired the misconception that this is a matter for
debate, and that this would be the place to debate it.  This would be wrong.
 I have given you advice on how you can increase your chances of getting an
answer to your question, a solution to your problem; not least, from me.
Take it or leave it.

I think that's what ASP does with <script runat=server>.
Also you could achieve something very similar with node.js and jsdom.

Thanks muchly for that Michael, this looks very interesting indeed! But there's quite a bit of stuff to wade through on that site - would it be asking too much for you to post just a snip of code showing me how to use ExpressJS to intersperse HTML with Javascript code?? :) (my head is kind of spinning reading all that stuff about "template engines" and whatnot on that site - I'm still not *that* adept at JS yet... :) (what's a "template engine", exactly?))
Thanks again for your help.
