Connect.js static middleware and coffeescript - coffeescript

I am trying to learn to use the Connect.js static middleware, but all the examples I find use the static command as either a function, or a getter, some use a method called use(), while others don't. Frankly, I'm stumped.
I am doing this in CoffeeScript. Here is my code:
connect = require 'connect'
fs = require 'fs'
server = connect.createServer (req,res)->
console.log 'Incoming Request:' + req.url
connect.static(__dirname="/static");
fs.readFile 'index.html', (err,data)->
if not err
res.write data
res.end()
server.listen 7243
The index.html has a .jpg file that is in the /static directory. The index.html file is served, but the image always appears as a broken link. Can someone tell me what I am doing wrong? Any info will be appreciated. Thanks!

Maybe you should change
connect.static(__dirname="/static");
to the correct
connect.static(__dirname+"/static");
or the longer
connect.static("#{__dirname}/static");

Protractor Custom Locator: Not available in production, but working absolutely fine on localhost

I have added a custom locator in protractor, below is the code
const customLocaterFunc = function (locater: string, parentElement?: Element, rootSelector?: any) {
var using = parentElement || (rootSelector && document.querySelector(rootSelector)) || document;
return using.querySelector("[custom-locater='" + locater + "']");
}
by.addLocator('customLocater', customLocaterFunc);
And then, I have configured it inside protractor.conf.js file, in onPrepare method like this:
...
onPrepare() {
require('./path-to-above-file/');
...
}
...
When I run my tests on the localhost, using browser.get('http://localhost:4200/login'), the custom locator function works absolutely fine. But when I use browser.get('http://11.15.10.111/login'), the same code fails to locate the element.
Please note, that the test runs, the browser gets open, user input gets provided, the user gets logged-in successfully as well, but the element which is referred via this custom locator is not found.
FYI, 11.15.10.111 is the remote machine (a virtual machine) where the application is deployed. So, in short the custom locator works as expected on localhost, but fails on production.
Not an answer, but something you'll want to consider.
I remember adding this custom locator, and encounter some problems with it and realised it's just an attribute name... nothing fancy, so I thought it's actually much faster to write
let elem = $('[custom-locator="locator"]')
which is equivalent to
let elem = element(by.css('[custom-locator="locator"]'))
than
let elem = element(by.customLocator('locator'))
And I gave up on this idea. So maybe you'll want to go this way too
I was able to find a solution to this problem, I used data- prefix for the custom attribute in the HTML. Using which I can find that custom attribute on the production build as well.
This is an HTML5 principle to prepend data- for any custom attribute.
Apart from this, another mistake that I was doing, is with the selector's name. In my code, the selector name is in camelCase (loginBtn), but in the production build, it was replaced with loginbtn (all small case), that's why my custom locater was not able to find it on the production build.

Frontend headless browser testing using CasperJS and configuration-files?

I tried to use CasperJS for headless browser testing using PhantomJS and wanted to have a config file or something to change Website URL, Username passwords etc. So finally I found NuclearJS. Do you guys know any other perfect way to do this? If I wanted to write a one from the scratch would like to know about as well.
I got a solution (not perfect ;) ) that is using multiple configfiles (for selector, execution, desktop, mobile, etc).
I include a in the execution of my casperjs tests a file that offers me all configs i need (i include also global functions there).
Lets guess the test execution looks like that:
casperjs test --includes=loadGlobals.js test_1.js
In the that example loadGlobals.js contains functions like that:
var fs = require('fs');
var config = {},
configFile = fs.read('config.json');
config = JSON.parse(configFile);
Probalby the config.json is looking like that:
{
"url": "http://www.yourTestUrl.com",
"variable_1": "bla",
"variable_2": "blub",
"nextTier": {
"variable_1": "blablub"
}
}
Now you can call in the test_1.js the variables of the config.json:
casper.start(config.url, function() {
casper.then(function() {
casper.echo(config.variable_1);
casper.echo(config.variable_2);
casper.echo(config.nextTier.variable_1);
});
})
casper.run();
You can use like that different configurationfiles, even to override it during tests if nessacary.
The tests should be written in the page object pattern style so they are highly maintable, espacially with a outsourced configuration.
NuclearJS i didn't know, but i will take a look into it, too.

meteor: database is undefined

I'm having some troubles understanding, what i believe is trivial but i can't seem to get my head around it.
I have this publish function in server.js (server only)
Meteor.publish("tikiMainFind", function(){
return tikiDB.find()
})
In app.js (server + client) i'm declaring this mongo collection:
tikiDB = new Mongo.Collection("tiki")
Why is it that this doesn't work in client.js
console.log(tikiDB.find())
//ReferenceError: tikiDB is not defined
Without any idea how you have your app structured, I agree with David Weldon's answer. Check File Load Order to see what order your files are getting loaded.

neo4jphp: Cannot instantiate abstract class Everyman\Neo4j\Transport

maybe a simple question but for me as starter with Neo4j a hurdle. I installed the neo4jphp with composer in the same directory as my application. Vendor-Subfolder has been created and the everyman/neo4j folder below is available. For a first test I used this code snippet from the examples:
spl_autoload_register(function ($className) {
$libPath = 'vendor\\';
$classFile = $className.'.php';
$classPath = $libPath.$classFile;
if (file_exists($classPath)) {
require($classPath);
}
});
require('vendor/autoload.php');
use everyman\Neo4j\Client,
everyman\Neo4j\Transport;
$client = new Client(new Transport('localhost', 7474));
print_r($client->getServerInfo());
I always stumple upon the error
Fatal error: Cannot instantiate abstract class Everyman\Neo4j\Transport
Googling brought me to a comment from Josh Adell stating
You can't instantiate Everyman\Neo4j\Transport, since it is an abstract class. You must instantiate Everyman\Neo4j\Transport\Curl or Everyman\Neo4j\Transport\Stream depending on your needs
So I thought I just need to alter the use-statements to
use everyman\Neo4j\Client,
everyman\Neo4j\Transport\Curl;
but this doesnt work, debugging shows, that the autoloader only get "Transport.php" instead of "everyman\Neo4j\Transport\Curl.php". For "Client.php" its still working ("vendor\everyman\Neo4j\Client.php") so I am guessing that the use-statement is wrong or the code is not able to handle an additional subfolder-structure.
Using
require('phar://neo4jphp.phar');
works fine but I read that this is deprecated and should be replaced by composer / autoload.
Anyone has a hint what to change or had the same problem?
Thanks for your time,
Balael
Curl is the default transport. You only need to instantiate your own Transport object if you want to use Stream instead of Curl. If you really want to instantiate your own Curl Transport, the easiest change to your existing code is to modify the use statement to be:
use everyman\Neo4j\Client,
everyman\Neo4j\Transport\Curl as Transport;
Also, you don't need to register your own autoload function if you are using the Composer package. vendor/autoload.php does that for you.
Thanks Josh, I was trying but it seems I still stuck somewhere. I am fine with using the default CURL - so I shrinked the code down to
require('vendor/autoload.php');
use everyman\Neo4j\Client;
$client = new Everyman\Neo4j\Client('localhost', 7474);
print_r($client->getServerInfo());`
The folder structure is main (here are the files and the composer.json with the content
{
"require": {
"everyman/Neo4j": "dev-master"
}
}
and in the subfolder "vendor" we have the "autoload.php" and the subfolder everyman with the related content. When I run the file I come out with
Fatal error: Class 'Everyman\Neo4j\Client' not found
which does not happen when I have the autoloadfunction. I guess I made a mistake somewehere - can you give me a hint?
Thanks a lot, B
Hmmm... I was just trying around and it seems the Transport CLASS is not needed in the use-statement and the class instantiation. This seems to work:
require('vendor/autoload.php');
use everyman\Neo4j\Client;
$client = new Client();
print_r($client->getServerInfo());
also valid for having a dedicated server/port:
$client = new Everyman\Neo4j\Client('localhost', 7474);
If you have more input I would be happy to learn more - thanks, all input & thoughts are very appreciated.

Zend framework: how to migrate a site

I'm trying to copy a site built on ZF from production to a localhost environment. All files and db contents were copied but I just get a blank screen. No errors, nothing
Changes made in config.ini I added an entry for development:production
general.host = "localhost:8888"
db.adapter = PDO_MYSQL
db.params.host = localhost:8888
db.params.username = bla
db.params.password = bla
db.params.dbname = db_name
bootstrap.php
$frontController->registerPlugin(new Initializer('development'));
.htaccess contains a few basic directives but if I put some random stuff at the top I don't get Internal server errors so I don't think it even reaches the .htaccess stage.
Did I miss some kind of configuration somewhere?
EDIT:
I have code below in my bootstrap but still get a blank page. Very quickly, it barely loads at all
$frontController->registerPlugin(new Initializer('development'));
$frontController->throwExceptions(true);
// Dispatch the request using the front controller.
try {
$frontController->dispatch();
}
catch (Exception $exception)
{
exit($exception->getMessage());
}
Try adding this line before running dispatch() on front controller object.
$frontController->throwExceptions(true);
On production systems throwing exceptions is almost always disabled, enabling it on dev could tell you more about the nature of the problem.
Yes, you probably missed some configuration.
Try setting display_errors=On in php.ini. You should be able to see what is going on.
Also, like suggested - try putting $frontController->throwExceptions(true) before calling dispatch().
Regarding the .htaccess file - you need to put the AllowOverride All (or anything valid, other than None) in your apache.conf/vhosts config.
