I don't really understand what is the name of the web server from meteor.js.
Because in PHP for example, by default, we are using ngix (or apache).
In python, we are using werkzeug (it's not really a web server in this case, but a library but the objective is similar).
In rails, we are using by default Puma.
But impossible to know what we're using in Meteor. We don't have a specific web server ? we are only using Meteor ?
I know the fact that meteor is a client/server framework built on top of nodejs (on the server side), but i don't find more precise detail about the name or the type of web server.
Node can serve up HTML pages, so unless you have some other situation going, it's the web server.

I'm using the dev-server of Modern Web to build client side code.
Now I want to add a small backend with a REST API, but I can't find any information of how to add a backend with a REST API to this server.
Any hints on where to start?
You could write a plugin for it but I wouldn't recommend it.
It's a development server designed for testing client-side code.
It isn't designed to be a production server, and if you are going to write a REST API then you will, presumably, want it to be usable in a production environment.
Build your API with a tool designed for it (such as Express.js or Spring Boot) and use CORS to make it accessible to the server you use for client-side development.
I am trying to build a desktop app using electron that retrieves mail from a specific mailbox (microsoft exchange server), now, i have looked around and read that mailbox connection should be done server side (the question was made by a guy building a web based app that is a little bit similar to what i want to do), but, since i am not really deploying a node js server but rather using electron, which, as far as i understand is like a desktop app version of node, im not sure on which approach to take. Should i use an api? does microsoft has any interface for this? or should i use a third party integration for it?
It looks like the Exchange Web Services API is only provided as a CLR assembly, so if you wanted to use it you'd need to:
write a C# console app that you then spawn from your Electron app
(and communicate via stdin/stdout), or
use the EWS API in your Electron app via Edge.js
Alternatively, you could probably just directly communicate with the exchange server using SOAP messages, but that could be a bit tedious to implement.
I am building a HTML/JavaScript application using AngularJS. It doesn't have a backend except some Perl scripts that spit JSON through a URL through which I display the data. One of the pages on this dashboard needs privileged access for which I had to add LDAP authorization.
The application is deployed on a WAMP server. Active directory is being used in the organization; but I am not quite sure how to establish the authentication in a pure html application without a backend. What is the usual process followed to handle such authorizations and how to achieve it?
You should write a web service (REST) in any language you want (JAVA C# PHP Node.js ...) who autenticate against your Open LDAP server and you'll consume it in AngularJS.
It's quite a classic problem.
Appears to be a perfect candidate for OpenID Connect. Use one of the many available libraries available.
I have a website built with HTML and JavaScript, served by Tomcat.
I need to add a no-SQL database to it, and I'm trying Couch DB. I'm in trouble, 'cause I understand how the DB works, but I have no idea how to connect it with my website.
I'm used to SQL, where I just have to make a connection and then send SQL queries. How can I instantiate a connection object to CouchDB, and use couchdb.js? Currently, Tomcat answers me with a cross domain issue, 'cause Tomcat and couchdb are on different ports.
Can anybody help me with the very basics?
Cross-origin resource sharing (CORS) will be implemented only in the next release of CouchDB (v.1.3).
It could be surprising but one should realize that it is not the "very basics" of CouchDB:
Most of CouchApp web apps developers serve their Ajax applications from CouchDB itself (using HTML shows, lists, and attached static pages).
Some developers use CouchDB as a simple database within a 3-tier architecture.
Others send requests to CouchDB from desktop or signed applications (Java, Flash, etc.).
So, sending Ajax queries from code retrieved from external sites was relatively rare.
My recommended advice would be to adopt one of the most common settings.
If it is definitely not suited to your case, then you can either test CouchDB's development version, or use a proxy so that CouchDB appears to be on the same server as your HTML code (until the next release).
First, you need to get familiar with curl, then you start to test your couchdb through command line.
Trying on the same machine that you installed couchdb.
$ curl localhost:5984
After that, try to access from a different machine using curl:
$ curl http://<your_couchdb_server_name_or_ip>:5984/
If you can't, you need to check if your server has a firewall that are blocking outside requests to your server on 5984 port.
Now, to access your couchdb from a ajax request you must configure the local.ini file:
[httpd]
enable_cors:true;
[cors]
credentials:true;
mehods:PUT,GET,POST,DELETE,OPTIONS;
origins:*;
Restart your couchdb and try again, this must fix you problem.
I have an application on my server that is called leaf.exe, that haves two arguments needed to run, they are: inputfile and outputfile, that will be like this example:
pnote.exe input.pnt output.txt
They are all on the same directory as my home page file(the executable and the input file). But I need that a JavaScript could run the application like that, then I want to know how could I do this.
I'm using just Apache, I don't have any language for web installed on it. My goal is to do a site using just JavaScript, without the help of anyother language than it, HTML and CSS.
You would need to make an Ajax request to the server - the server would then have a handler that would then invoke the executable with the appropriate parameters.
Without know which web server technology you are using, it's harder to give a more concrete answer (ex: ASP.NET, PHP, Ruby, etc).
EDIT: If you're talking about doing this without any kind of server side resources, then this is impossible, and for good reason. Think of the security exploits!
Any other way to this without using other languages that need to be installed on the server?
No, but you almost certainly already have languages on the server. If it's a Linux, BSD or OSX server you've got shell script; if it's a Windows server you've got JScript and VBScript via Windows Scripting Host (using a cscript.exe hashbang).
JavaScript is for Client Side of a web application, so you won't be able to directly use javaScript to access server side files. As mentioned by Tejs, you should use Ajax to make a call to server side and then use appropriate server side routine to do the task.
Even at client side, most browsers don't allow accessing of any resource( e.g files) by javaScript code.
For server side javascript in Apache you could use Sun ONE Active Server Pages, formerly known as Chili!Soft ASP. For an IIS server, javascript is plainly available as asp-language.
Look into Rhino and node.js. I dont know a lot about this, but thats a route you can use for serverside javascript.
